10:11 The location permission is required by modern Android versions in order to be able to detect BLE devices (it's not required for regular Bluetooth devices). It's Google's decision to require this permission. Nothing wrong with the app itself.
Yea, I believe it's because with the BLE permission itself, it's pretty easy for an app to start profiling devices and correlate location anyway. There's a lot of BLE advertising beacons out there in places that can be used to trigger stuff and log who is where so it's effectively location without GPS or wifi scanning so some companies were using it to clandestinely track people without their knowledge.
@@EEVblogother way to do it is to request draw over other app permission, that way you trick android into the app is always in foreground and don't need location in background permission, but the app will launch the window to allow permission automaticly anyways so it's easy to just do it

We use them in ISM laser scanning microscopy in form of SPAD arrays or line arrays..
@@ZomB1986 It only detects photons, so gamma or X-ray. Beta radiation can be indirectly detected via Bremsstrhalung radiation. There are two main advantages to scintillation detectors. The first is they are very sensitive, you will get a much higher reading from one compared to a geiger counter. They can also be used to detect weaker sources of radiation that wouldn't show up with a geiger counter. The second advantage is the ability to discriminate between the energies of detected photons. You can think of it like a nuclear fingerprint. The scintillator and electronics can work together to not just tell you that radiation is present, but to tell you exactly what isotope is causing the radiation.
The spectrum data needs to be cleared before attempting to take a new reading. There was no change in the spectrum with the smoke detector because you were averaging a few seconds of exposure to it against over 4 hours of background data. If you clear the data beforehand it will give you a very clear reading and correctly identify it as Americium-241 after a minute or two. As for the banana, the radiation is too low to detect with a live reading. If you take a day long spectrum with the detector placed against it you should see a photopeak for K-40 appear.
The Radiacode is a scintillator based w/o a gieger tube. There is a crystal that emits light which is detected by a solid state photomultiplier. With regard to the smoke detecter, the radiation is Alpha which a scintillator does not detect. The Alpha does result in secondary radiation products which are from Alpha particle decay. These decay products are weak Gamma which the Radiacode is detecting. Alpha can be blocked by a piece of paper, but the secondary breakdown can contain Alpha and Beta particles.
Not sure if that's what you meant, but the gamma peak at ~60keV comes directly from the americium daughter product after the alpha decay, not some of the other nuclides in the decay chain. You won't detect any of the other decay products in the smoke detector.
Yep, mentioned in the manual. I would have thought they'd make a 48V - > 12V daughter board that bridges the two pin headers but seems they leave that up to the customer.
Not a GM counter but a scintillation one, it uses a photomultiplier and a crystal that emits photons when hit by gamma radiation (not sure if alpha or beta do it too). Still saving my bottlecaps... Get a discarded ethernet switch and use it for an enclosure for the LattePanda, making the new front and rear I/O shields.

@@EEVblog I meant it literal. You would have to build a lead castle. Bricks of lead, to shield the experiment from the backround radiation.

For the start, it would be easier to make a spectrum from the americium source from the smoke detector (Don't forget to reset the spectrum before the measurement)
@@EEVblog The efficiency of the small scintillator is very low at the K-40 peak and the concentration of K-40 in a single banana is also very low. You'd have to collect a couple bananas, char the banana peels, collect the ash (to concentrate the K-40) and put that into a lead castle (to decrease the background raditiation) with the detector for like a day or two to see the peak. It's not that easy unfortunately.

a long time ago, I found an image on the webs that says it's Cesium isotopes in bananas. It also has a warning! You should not eat more than _6600_ bananas per _second_ in order to avoid a _lethal_ dose of radiation :D
@@SystemX1983 It's the Potassium. You just need a fair bit of it in one place for it to be detectable. You can take just about any geiger counter and place it on a one pound bag of potassium chloride and get an above background reading. K-40 is the specific isotope responsible.
Dave, you missed the most impressive part on the Radiacode, the gamma spectrometer... Regarding the Latte Panda, in their first version they had an ATMEL Arduino Leonardo "co-processor". It does not look like this new one has?
I wondered when you'd get your hands on the Radiacode as it's a really cool product and extremely popular in that field already. Nice to see you also taking it apart ;)
Radiacode is a nice product. I have one (older model). The strength is not just being a sensitive radiation detector but being able to analyze energy. Mobile app works well and included a reasonable database for peak identification too. Battery life is pretty good too (runs days on single charge). Bananas like other foods containt K-40. I can measure which part of the bed I sleep in with radiacode in reasonable time. When you have K-40 in food, you output is in sweat that concentrates on where you spend long time in similar position. The black blob is a PIN-diode with a scintillation chrystal (thallium doped CsI)
i had an experimental radiation treatment for my brain tumour which was injecting actinium-225 into my head. My Soeks geiger counter was reading 6 microsieverts next to my head. Fun times.
see this is why i'd be hesitant to have a "mailbag" if i was a popular youtuber in this general category, some genius would think it would be a neat gift to send in one of the old cobalt 60 sources or something.. "oh yeah i have this one thing on the shelf someone sent, never got to looking at it but i do notice i feel sick whenever i'm spending time in this room"
To what type of radiation is the dosimeter sensitive? And how accurately? I would like to have some more info on that. Btw: a smoke alarm emits alpha radiation, so it definately picks that up.
The Americium-241 also emits a small amount of gamma radiation. That's what it was picking up. You need a Geiger tube with a thin mica window to detect alpha radiation.
That is a really cool little monitoring device! My question is, is there any concern that a normal STM32 would encounter bit errors from radiation? Shouldn't the processor be shielded or something? (At the levels where you might want a "get out now" alarm, I mean.)
These scintillator devices are very sensitive, the sensor will saturate long before the radiation level gets high enough to interfere with the microprocessor. It's simply not designed to operate under 'get out now' kind of situation. For that you need GM tubes or ionization chambers.
There is a very small risk, but the probability is extremely low, for it to be a major concern you'd have to expose it to a very high dose rate at which point you would risk damaging the detector anyway (eg. placing it in a high energy X-ray beam). Proper industrial "Electronic Personal Dosimeters" (EPDs) used in like nuclear power plants and hospitals where they're considered safety critical do consider this, but mitigate it mostly in software checks and watchdogs. It's only in spacecraft design where the energy levels and dose rates are like 1,000x what would be fatal to humans (5 kGy) that you need shielding and radiation hardened ICs.
I have a MightyOhm geiger tube based on ATiny85 and has no problems (other than saturating measures) reading the Iiodine 131 emissions from a person that has received a dosis for hipothiroidism an hour ago. That's a huge count per second pulses.... I mounted also an esp e12 to add wifi access point capabilty and has no problems also.
When I was a kid, wrist watches and alarm clocks used Radium or Tritium for the photo luminescent green dots for visibility at night. (1960s onwards) Both apparently radioactive. I believe today safer materials are used. Digital LED watches were only introduced in the 1970s
Tritium is still used today. It's a gas that is sealed in a glass capsule with a phosphor that glows. It's safe as long as you don't ingest it. Radium paint is dangerous. It's still very radioactive long after it stops glowing. The paint will flake off easily and spread radioactive contamination.
For some reason I like to collect smoke alarm radiation sources in a metal box. It would be interesting to put the radiation monitor in the box to see how high it can go.
My LattePanda Mu come with windows 11 pre-installed I was really impressed with performance so far, I used a 12v usb 3A and now I have a cheap 19v 4.75A power supply so it has more power, but both worked pretty good. Im still trying to find some library files for development for the UART and SPI, I did find some windows serial drivers for them. but I would like some includes and lib or some SDK.
The Lattepanda doesn't convince me. I don't see any advantage with this large ITX motherboard over normal ITX motherboards with a soldered Intel or AMD CPU. The comparison with the Raspberry Pi is also flawed. The Raspberry Pi is much smaller and doesn't need an extra board and also has GPIO pins. And before I connect several LattePandas to form a node, I'd rather use a high-end multi-core processor. So what exactly was the LattePanda developed for?
Observers have noted that the Cesium Iodide scintillator, used in these device models, can distinguish gamma ray energy proffering identity of radioactive sources. Technically this can be done, but since there are about 1000 gamma and X rays in the "everyday" world there is only contrived hope of identifying anything. Typically contrived, the industry model is to construct a test that is best described as " if you know the answer then you can make the machine tell you that answer. The fundamental problem with identification is gross ambiguity due to small detector size, low quantum efficiency, resolution killing noise, temperature variations, fingerprint overlap, and more. What utility is remaining is a dose estimate which is sold as at least somehow useful. Yes dose rates are useful but you will find the utility is that government users will note alarms on radioactive medical patients and not nuclear threats thereby quickly retraining the users to ignore the results. Owning one thereafter is a status symbol purporting to divine secrets that by far most operators are not privy to.
You’d be surprised how many times you are exposed to radiation through out your day to day life. Depending on how often you are near medical offices like dental offices, urgent care, imaging centers and hospitals. Even vet clinics. You might be getting a solid dose at various points throughout a given day. Which this thing will detect and alert on. Street level, north east corner of the intersection at 23rd and Broadway in NYC had an 18 second event that alarmed. A fairly significant dose rate for walking around on the sidewalk at, 5.68 uSv/h, with 980 cps. Medical offices just a half block east are my suspected sources. Basically a CT scan worth, as we waited on a crosswalk to clear. I do worry about the folks in the condos/apartments though. It’s one thing to get zapped passing by somewhere you may never get to visit again. Whereas living next to it is another thing. For comparison, TSA at LGA scanned my bag with what turned out to be an americium source, at 50.0k cps, 1.0k uSv/h, and again at 38.9k cps, and 1.0k uSv/h. I detected the source with a wicket spike in the spectrum. My flight with a window seat was on average 16 cps, 0.94 uSv/h. It’s an amazing little tool, and even though it’s pricey, it does a lot of stuff that historically, involved benchtop equipment to do, and it’d still cost a lot more. The battery lasts for days, even with it running in my pocket or on my desk all day and evening. The only complaint I have is that the Apple app can crash when your phone looses cell signal. It can also get stuck in a crash loop, if the Radiacode 102 is on, and you then try to relaunch the app, to resume a track session. You have to power off the device. Start up the app. Turn on the device, and end the track session. Then it’s stable again. At least that drop of cell signal is what I suspect is causing it. Because that street where it always happens is a know cell phone call dropping location.
I think the GPS is paired with radiation readings. AFAIK, Clive was able to walk around town and track readings. But yeah, being able to turn the GPS off would be a good idea.
That RadiaCode app, wanting the location all of the time, would be of special interest if onder the logs you could find back where through your trip peaks appeared with their location.
It might do that, but the reason it needs location is because constantly requesting location is the only reliable way to keep an app alive in the background (vs suspended with occasional wakeups) on Android or iOS.
Looks like it does energy channels for isotope identification. Looks a useful tool, not sure how accurate it would be. Probably best used as a dose rate meter rather than a contamination. Software probably too heavy for the novice...Radio labs love it though
The spectrum function is quite easy to use, and it has an overlay that marks photopeaks to identify common decay chains for easier identification. It's accurate enough to detect various photopeaks from Europium in trinitite if you calibrate it before hand.
I honestly think your only option for a case for that Latte Panda is gonna be a 3D Printed case :/ ... not unless the Latte Panda company already makes one for it.... BUT I really don't think it's meant to be IN a case anyway... it would be so much of a pain opening the case every time you has to hook up a wire to the GPIO, or pull out an SD Card..... yea I don't think they intended for it to be in a case .... Oh I know, you could get it onto a test bench "case" ..... not sure if you're familiar with computer test-bench "case" but it's usually just an elevated platform (so you can keep the ATX PSU underneath it and the wires can easily come up into the motherboard) that you screw the motherboard onto with traditional screws but where your PCIe cards would normally attach to the case they typically have a simple system that ill hold the PCI card (like your GPU or a NIC or Video Capture, etc) in a solid position and keep it from any movement, but instead of a screw holding it down there might be some kind of latch system to EASILY unlatch and remove the GPU and swap in a new one ... these types of test benches are meant for people that need to swap pieces of the computer in and out a lot, quickly and easily, for example a youtuber that reviews GPUs or CPUs ..... - I think this might actually be your best bet for your Latte Panda.... I don't think there are gonna be ANY Cases (ITX or otherwise) that can accommodate the I/O being on the back AND the front, PLUS some n the side like the SD Card.... you SHOULD be able to find one on amazon, but I think your best place to search would be newegg ... GOOD LUCK!
The plant fertilizer Miracle Gro will give a radiation reading a bit above background. The one I was testing was labeled Miracle Gro All Purpose Soluble Plant Food.
250 is very cheap for all the features it provides. You have to compare it to other similar products in that field. You can easily pay thousands of dollars for a gamma spectrometer.
Yep. I was just about to comment this. It's a weird quirk of how Android deals with Bluetooth discovery permissions. They were supposed to break this out in Android 13 to be its own permission setting, but I don't think they ever did.
Yes I know that, the 121GW works the same way. but in this case it's not only needs location permission, but permission all the time when the app it's on. it's actually two levels of permission, and that's usually not needed.
The bfact that radiation detectors app requires your location all the time for some reason is a put off to me.Your location is not necessary to detect radiation.
That may be an android requirement, you need the location permission because an app could use Bluetooth to determine your location. Not sure about the all the time part though, I thought it was only for scanning. Probably worth further investigation.
@@RandyDarkshade2 how many communicate with devices via Bluetooth? Mine shows 5 apps with all the time permission, 14 with while in use, and 32 denied. You really only get asked once for apps you use regularly.
At the very least they enable them. It's the only reason I can think of why the company that developed reCAPTCHA refuses to implement it on their most popular platform.
the gm tube is way too small to be very sensitive. but if your going to die, it would let you know. Dang I take that back. it picks up that smoke alarm very well.
It isn't a GM-tube. The radiacode uses a scintillation crystal, they are extreemly sensitive. That smal 1x1x1 cm crystal is likely 10 to 20 times more sensitive than a 2" pancake probe geiger counter.
DUDE, terrible radiacode review...... You get given a device like that, at least do them the favor of a real review. That was shit. No, I don't work for them, or get their shit for free.
Dave, you do a disservice to the people who sent you this by not reading the instructions and not understanding how the device works and should be used. All you've produced here is half an hour of waffling incorrectly about something you don't have a clue how to use, let alone review. You can do better than this!

It also has a warning! You should not eat more than _6600_ bananas per _second_ in order to avoid a _lethal_ dose of radiation :D
@@SystemX1983 It's the Potassium. You just need a fair bit of it in one place for it to be detectable. You can take just about any geiger counter and place it on a one pound bag of potassium chloride and get an above background reading. K-40 is the specific isotope responsible.
Dave, you missed the most impressive part on the Radiacode, the gamma spectrometer...
Regarding the Latte Panda, in their first version they had an ATMEL Arduino Leonardo "co-processor". It does not look like this new one has?
Nope, just the N100.
I wondered when you'd get your hands on the Radiacode as it's a really cool product and extremely popular in that field already. Nice to see you also taking it apart ;)
Radiacode is a nice product. I have one (older model). The strength is not just being a sensitive radiation detector but being able to analyze energy. Mobile app works well and included a reasonable database for peak identification too. Battery life is pretty good too (runs days on single charge).
Bananas like other foods containt K-40. I can measure which part of the bed I sleep in with radiacode in reasonable time. When you have K-40 in food, you output is in sweat that concentrates on where you spend long time in similar position.
The black blob is a PIN-diode with a scintillation chrystal (thallium doped CsI)
The pads on the back side are an eSPI interface according to the I/O plan.
Those radiocodes are super neet. I just graduated with a nuclear engineering degree and I'm thinking of getting one to play with.
Yeah, definitely a cool toy to play around with :D
I think the position permissions are due to the bluetooth, since bluetooth can be used to get your position 🙄
Looks like the board files are available for the Lite version of the carrier board in the GIthub repository. Can you do a video on it? 🙂
i had an experimental radiation treatment for my brain tumour which was injecting actinium-225 into my head.
My Soeks geiger counter was reading 6 microsieverts next to my head. Fun times.
That's not too bad, that was probably some time after the procedure, right? I'd expect more than that close to your head.
It's not a Geiger detector. It's actually a scintillation detector, which is why it can plot an energy spectrum and identify sources.
Worked in a university nuclear reactor lab twenty odd years ago. Didn't have fancy gadgets like that. Would have been handy.
see this is why i'd be hesitant to have a "mailbag" if i was a popular youtuber in this general category, some genius would think it would be a neat gift to send in one of the old cobalt 60 sources or something.. "oh yeah i have this one thing on the shelf someone sent, never got to looking at it but i do notice i feel sick whenever i'm spending time in this room"
At my location the Radiacode 102 shows 0.03uS/h background.
What's it good for apart from finding radon leaks in your basement?
panda would make a great firewall
Are you going to review the Siglent SDS800X HD?
wow 2 boxes .. does it protect the Giger module from external sources while in transit?
Radioactive Drew uses one of these. It has the ability to identify the isotope by energy levels when used with the app.
Interesting that the reading went from 0.09 to 0.10 when in the case.
To what type of radiation is the dosimeter sensitive? And how accurately? I would like to have some more info on that. Btw: a smoke alarm emits alpha radiation, so it definately picks that up.
The Americium-241 also emits a small amount of gamma radiation. That's what it was picking up. You need a Geiger tube with a thin mica window to detect alpha radiation.
It's sensitive to gamma radiation. Maybe some beta due to undesired secondary processes. But definitely targeted at gamma.
That is a really cool little monitoring device! My question is, is there any concern that a normal STM32 would encounter bit errors from radiation? Shouldn't the processor be shielded or something? (At the levels where you might want a "get out now" alarm, I mean.)
These scintillator devices are very sensitive, the sensor will saturate long before the radiation level gets high enough to interfere with the microprocessor. It's simply not designed to operate under 'get out now' kind of situation. For that you need GM tubes or ionization chambers.
There is a very small risk, but the probability is extremely low, for it to be a major concern you'd have to expose it to a very high dose rate at which point you would risk damaging the detector anyway (eg. placing it in a high energy X-ray beam). Proper industrial "Electronic Personal Dosimeters" (EPDs) used in like nuclear power plants and hospitals where they're considered safety critical do consider this, but mitigate it mostly in software checks and watchdogs. It's only in spacecraft design where the energy levels and dose rates are like 1,000x what would be fatal to humans (5 kGy) that you need shielding and radiation hardened ICs.
I have a MightyOhm geiger tube based on ATiny85 and has no problems (other than saturating measures) reading the Iiodine 131 emissions from a person that has received a dosis for hipothiroidism an hour ago. That's a huge count per second pulses.... I mounted also an esp e12 to add wifi access point capabilty and has no problems also.
When I was a kid, wrist watches and alarm clocks used Radium or Tritium for the photo luminescent green dots for visibility at night. (1960s onwards) Both apparently radioactive. I believe today safer materials are used. Digital LED watches were only introduced in the 1970s
Tritium is still used today. It's a gas that is sealed in a glass capsule with a phosphor that glows. It's safe as long as you don't ingest it.
Radium paint is dangerous. It's still very radioactive long after it stops glowing. The paint will flake off easily and spread radioactive contamination.
For some reason I like to collect smoke alarm radiation sources in a metal box. It would be interesting to put the radiation monitor in the box to see how high it can go.
Recently built a new pc and my first win11 machine. It’s different, but almost exactly the same as win10 :)
My LattePanda Mu come with windows 11 pre-installed I was really impressed with performance so far, I used a 12v usb 3A and now I have a cheap 19v 4.75A power supply so it has more power, but both worked pretty good. Im still trying to find some library files for development for the UART and SPI, I did find some windows serial drivers for them. but I would like some includes and lib or some SDK.
The Lattepanda doesn't convince me. I don't see any advantage with this large ITX motherboard over normal ITX motherboards with a soldered Intel or AMD CPU. The comparison with the Raspberry Pi is also flawed. The Raspberry Pi is much smaller and doesn't need an extra board and also has GPIO pins.
And before I connect several LattePandas to form a node, I'd rather use a high-end multi-core processor.
So what exactly was the LattePanda developed for?
How do you feel about the new Australian "solar tax", Dave?
Observers have noted that the Cesium Iodide scintillator, used in these device models, can distinguish gamma ray energy proffering identity of radioactive sources. Technically this can be done, but since there are about 1000 gamma and X rays in the "everyday" world there is only contrived hope of identifying anything. Typically contrived, the industry model is to construct a test that is best described as " if you know the answer then you can make the machine tell you that answer. The fundamental problem with identification is gross ambiguity due to small detector size, low quantum efficiency, resolution killing noise, temperature variations, fingerprint overlap, and more. What utility is remaining is a dose estimate which is sold as at least somehow useful. Yes dose rates are useful but you will find the utility is that government users will note alarms on radioactive medical patients and not nuclear threats thereby quickly retraining the users to ignore the results. Owning one thereafter is a status symbol purporting to divine secrets that by far most operators are not privy to.
You’d be surprised how many times you are exposed to radiation through out your day to day life.
Depending on how often you are near medical offices like dental offices, urgent care, imaging centers and hospitals. Even vet clinics. You might be getting a solid dose at various points throughout a given day. Which this thing will detect and alert on.
Street level, north east corner of the intersection at 23rd and Broadway in NYC had an 18 second event that alarmed. A fairly significant dose rate for walking around on the sidewalk at, 5.68 uSv/h, with 980 cps. Medical offices just a half block east are my suspected sources.
Basically a CT scan worth, as we waited on a crosswalk to clear. I do worry about the folks in the condos/apartments though. It’s one thing to get zapped passing by somewhere you may never get to visit again. Whereas living next to it is another thing.
For comparison, TSA at LGA scanned my bag with what turned out to be an americium source, at 50.0k cps, 1.0k uSv/h, and again at 38.9k cps, and 1.0k uSv/h. I detected the source with a wicket spike in the spectrum.
My flight with a window seat was on average 16 cps, 0.94 uSv/h.
It’s an amazing little tool, and even though it’s pricey, it does a lot of stuff that historically, involved benchtop equipment to do, and it’d still cost a lot more.
The battery lasts for days, even with it running in my pocket or on my desk all day and evening.
The only complaint I have is that the Apple app can crash when your phone looses cell signal. It can also get stuck in a crash loop, if the Radiacode 102 is on, and you then try to relaunch the app, to resume a track session. You have to power off the device. Start up the app. Turn on the device, and end the track session. Then it’s stable again. At least that drop of cell signal is what I suspect is causing it. Because that street where it always happens is a know cell phone call dropping location.
I think the GPS is paired with radiation readings. AFAIK, Clive was able to walk around town and track readings. But yeah, being able to turn the GPS off would be a good idea.
Yes, I didn't show the mapping mode.
It doesn't actually use GPS, location services permissions are needed for Bluetooth connectivity.
Ame-ri-cium :D
Not great, not terrible.
Thanks, I was shooting for average.
There is no graphite to see here.
That RadiaCode app, wanting the location all of the time, would be of special interest if onder the logs you could find back where through your trip peaks appeared with their location.
It might do that, but the reason it needs location is because constantly requesting location is the only reliable way to keep an app alive in the background (vs suspended with occasional wakeups) on Android or iOS.
The app has a radiation mapping function that does exactly what you described.
@@coyote_den Yes, but annoying that you have the enable this just to use it once.
@@RMX7777 🤗 Progress...

Dave please review a RooBadge, it's some VW snake oil made with corporation with Melbourne university
It's not about the radiation sources you have to measure it's about the radiation sources you don't know you have till you measure them.
Looks like it does energy channels for isotope identification. Looks a useful tool, not sure how accurate it would be. Probably best used as a dose rate meter rather than a contamination. Software probably too heavy for the novice...Radio labs love it though
The spectrum function is quite easy to use, and it has an overlay that marks photopeaks to identify common decay chains for easier identification. It's accurate enough to detect various photopeaks from Europium in trinitite if you calibrate it before hand.
I'm waiting for a P.K.E. Meter or Aurascope in the next Mailbag
I honestly think your only option for a case for that Latte Panda is gonna be a 3D Printed case :/ ... not unless the Latte Panda company already makes one for it.... BUT I really don't think it's meant to be IN a case anyway... it would be so much of a pain opening the case every time you has to hook up a wire to the GPIO, or pull out an SD Card..... yea I don't think they intended for it to be in a case ....
Oh I know, you could get it onto a test bench "case" ..... not sure if you're familiar with computer test-bench "case" but it's usually just an elevated platform (so you can keep the ATX PSU underneath it and the wires can easily come up into the motherboard) that you screw the motherboard onto with traditional screws but where your PCIe cards would normally attach to the case they typically have a simple system that ill hold the PCI card (like your GPU or a NIC or Video Capture, etc) in a solid position and keep it from any movement, but instead of a screw holding it down there might be some kind of latch system to EASILY unlatch and remove the GPU and swap in a new one ... these types of test benches are meant for people that need to swap pieces of the computer in and out a lot, quickly and easily, for example a youtuber that reviews GPUs or CPUs .....
- I think this might actually be your best bet for your Latte Panda.... I don't think there are gonna be ANY Cases (ITX or otherwise) that can accommodate the I/O being on the back AND the front, PLUS some n the side like the SD Card.... you SHOULD be able to find one on amazon, but I think your best place to search would be newegg ... GOOD LUCK!
The plant fertilizer Miracle Gro will give a radiation reading a bit above background. The one I was testing was labeled Miracle Gro All Purpose Soluble Plant Food.
W11 is not horribly different from W10, but the differences are not particularly useful either.

yes it is cool but £250.- is not cheap, higher model £555.-....
250 is very cheap for all the features it provides. You have to compare it to other similar products in that field. You can easily pay thousands of dollars for a gamma spectrometer.
Dave get the app going it will blow your mind ... or it did mine
Word of the day: Groovy ;-)
Dave iirc from my dev days , the app needs location premmision for the BT to work...
Yep. I was just about to comment this. It's a weird quirk of how Android deals with Bluetooth discovery permissions. They were supposed to break this out in Android 13 to be its own permission setting, but I don't think they ever did.
Yes I know that, the 121GW works the same way. but in this case it's not only needs location permission, but permission all the time when the app it's on. it's actually two levels of permission, and that's usually not needed.
@@EEVblog might report that to the devs. They selected the wrong object when setting up perms declaration

The bfact that radiation detectors app requires your location all the time for some reason is a put off to me.Your location is not necessary to detect radiation.
Someone needs to reverse engineer it and write an open source program that doesn't require a phone or GPS location.
That may be an android requirement, you need the location permission because an app could use Bluetooth to determine your location. Not sure about the all the time part though, I thought it was only for scanning. Probably worth further investigation.
@@Noxonomus As an Android user, I have barely been asked by apps to use my location.
@@RandyDarkshade2 how many communicate with devices via Bluetooth?
Mine shows 5 apps with all the time permission, 14 with while in use, and 32 denied. You really only get asked once for apps you use regularly.

the gm tube is way too small to be very sensitive. but if your going to die, it would let you know. Dang I take that back. it picks up that smoke alarm very well.
It isn't a GM-tube. The radiacode uses a scintillation crystal, they are extreemly sensitive. That smal 1x1x1 cm crystal is likely 10 to 20 times more sensitive than a 2" pancake probe geiger counter.
So , you have Downgraded to Windows 11
