Taking Infrared Aerochrome images with an iPhone!
Переглядів 486Рік тому
Using just an iPhone and an infrared 720nm filter you can take infrared images similar to the Kodak Aerochrome film. This creates the iconic pink foliage that Aerochrome is know for on a shoe string budget. To perform this you will also need access to a photoshop like image processing software. I use Affinity Photo on the iPad Pro for this process. teaandtechtime.com/cheapest-infrared-aerochrom...

Hey I met you at opensauce love this project I'm thinking on working on something similar using a focal reducer is a great idea is this just one from a telescope or is a custom made one?
The focal reducer lens is from Amazon but I rehoused it in a 3d printed adapter to save space. Links for both should be on my website project article. Great meeting you as well, OpenSauce was super hectic so I don’t quite remember what we talked about, but feel free to email or reach out on my socials for more help or just to share progress :)
@@teaandtechtime Brilliant thank you, yeah it was a bit hectic was good to talk to you. yeah would love to keep in contact I'll check out your site thanks :)
How is the battery life?
A couple hours usually, but has a physical power button so the standby time is basically as long as the batteries natural discharge rate. Check out the my attiny voltage monitor blog post for more info on power supply
Works for me, yay! Thank you so much!
That dial in focus mechanism would be great on any of my HQ camera projects! I hate having to screw and unscrew C-mount extension tubes all the time!
Ya I think it wouldn’t be too difficult to extract that part of the model out into a single box with a tripod mount. Might be a bit before that happens though haha
Amazing stuff man. What kind of focal reducer did you use on the v1? Just a random hobby-telescope reducer? And where did you get the 1-inch sensor for the v2?
Ah, probably the IMX 283 right? Maybe for v3 you can consider the m43 sized IMX294. I saw someone get it to work on a pi forum but unfortunately YT won't let me provide the link without deleting the comment. It was noted that a "V4L2 subdevice driver" and a "4-lane MIPI CSI" were required.
Ya the focal reducer is linked in my original pieca camera build documentation on teaandtechtime.com the 1in sensor is the imx283 called the “one inch eye”
A m43 would be cool, no available modules for purchase yet (or maybe ever) I want to keep the build fairly accessible by using things people can buy off the shelf. The pi5 version will be able to swap out different sensors for budget and availability (more modular)
@@teaandtechtimedid you mean you couldn't buy the IMX294 as an individual part? If so that's a shame bc m43 is about the most accessible, adaptable, open-source, and affordable mirrorless mount there is. Bit of a stretch, but maybe there's a way to control the focusing motors on a cheaper modern-ish lenses (for manual focus only). It's focus ring is probably just some potentiometer and another 2 of the metal contacts control the focus-motors' power. But that's just me being optimistic. Your next Peica version sounds super cool. If people can build modular cameras on a budget that would be a game changer. Lens and sensor customization? awesome.
You can get imx294 sensors and there is an open source pcb carrier called fourthirdseye but you need to assemble it yourself which I could probably do but those small parts are a pain to do manually. github.com/will127534/FourThirdsEye
absolutely incredible.
Thanks!
This is legit,..thanks... you've just earned yourself a sub. 👍👌
Love the project, was thinking bout making wireless volume knob for phone/desktop. What battery are you using and how long does it last when fully charged. Also did you manage to fix the issue with not being able to power the device on when it's not connected to usb. thanks!
Have not been able to dive into the boot issue, might need a boot loader update. For the battery I am just using a AA style Lithium battery and I seem to get like months of run time.
What thread size did you use for the r72 filter for the v2 holder? Definitely trying to give this a go but want to make sure I get the right filter size for the mount.
It’s a 37mm for the second version
Nice job. I had exactly the same problems and questions you had while building mine.
Great job, but DAMN do I regret sticking down the antennae. They should TOTALLY be spaced off from the metal with something.
On version two of the filter holder, what is the 720nm infrared filter size that you use? I can’t seem to see or find that size on the actual page. I accidentally ordered the 52 mm and it doesn’t fit.
I was wondering the same thing. Want to make sure I order the right thread size the first time haha
37mm for the updated 3d printed filter mount
this whole time I thought my two options for infrared were expensive digital setup, or go with film and have it be a whole long process and also I'd have to basically shoot infrared for a whole roll and nothing else. so you're telling me I could have just used my iPhone and a $19 filter off of amazon‽
It’s pretty amazing how well it works, you just need to take 2 images of the same I just fairly quickly. You then just need to combine in post
Any useful life update or any problem with this battery hack? How many rolls have you shot with the point and shoot? :)
I’ve done like 4 to 5 rolls on the point and shoot with one battery and minimal flash
how long did you waited since payment?
It was like 10months from the first day it came out :/
hell slow, might need to wait when pi 8 or 12 is released
Hi, thanks for sharing the video. Which pins on the XIAO did you connect the switch to?
D4 and GND
I wonder after some months of utilisation , does this affect the body itself causing damages to it ? Technical question but is it the same amount of energy that is sent ? Is it running good ? Asking it in a very good way Willing to turn my usage into something more ecoresponsible ❤️✊
hey i also tried this but the camera wont turn on and the battries gets hot when i put them in camera
Interesting, make sure to check the polarity and for any shorts with a multimeter.
This is really cool! I see you layered a green and yellow bingo chip. If the green chips I have lean more bright, apple green, rather than the cool blue-green of yours, would it still be necessary to layer the yellow with it?
I dont think you need the yellow. On my second version I just used a green filter
so how many shots can you get from 36 exposures. 12?
Holy shit people, clock radios are like, cheaper then dirt, why are you using your phone?
I like having 10,000 alarms :)
Loved the video and thank you for the detailed blog post. 😊 Let me see if I can build this to "inspire" kids to take a serious look at learning 3D/electronics/programming. Do continue to post projects that involve all the three... 👍 -- From a person who failed miserably in making a tea coaster that senses the tea temperature (an Arduino project)
Is that a kailh box jade 💀
I want one to replace my tablet, wonder how long does the battery last with 4G module fitted. Suppose I use 2 batteries, running Thunderbird to check mail every 15min., turn off the screen and keyboard backlight, will the thing last 5hrs. or so ?
good work, i ordered uconsol, still waiting to get it.
I had the 3d piece printed from a website online and it came out tiny hahahahaha.. will have to try ordering again. Might've chosen the wrong dimensions.
Oops! Hopefully it comes out correct the next time
double check you are selecting the right units for dimension. A lot of times if someone designs something in US standard (inch) and you import it to 3d printing software to slice it, the software only can use Metric units so it results in the size of the model being reduced by 2.54 times.
I'm trying to follow your v2 guide to recreating this aerochrome IR Filter camera, but I'm not sure how you were able to pop the Aliexpress plastic color filters out of the frames they came in... Seems like the filters are plastic but the frame is metal so I'm worried about breaking the filter before getting it out of the frame... Any tips?
There should be 2 notches in the frame that is used to screw the plastic filter into it. I used a pair of calipers (very carefully) to remove mine but there are special tools you can get.
as mentioned unscrew it with the two notches I just used a small flat head screwdriver and unreasonable force. The IR cut filter I had came mounted without the notches so I made my own with a hacksaw. You can protect the filters with masking tape both if you need to hacksaw and if you are like me and unscrewing the retaining ring with a flathead.
Looks great, ordered mine! Can you do a follow up after some use time? And comment on WiFi, battery, etc.?
Ya I’m working on a few things with the uConsole and those were already on the list!
Way cool & the photos are nice.👍
Thanks! V2 should be coming out soon :)
Not working
Nice work! Just wonder if you may need any services, like PCBs or 3D printing, in the upcoming content, if so, we'd be glad to sponsor you.🙌 (PCBWay Daisy)
How long did you have to wait for it? Is it really 3 months delivery?
@@teaandtechtime oof, that's rough. I hope it was worth the wait for you. I'm not too bothered by a short wait, especially since I can do monthly payments on it, but 3 months is definitely pushing it for most people.
May I advise moving the tripod mount to be inline with the center of the lens? This is how most cameras do it as it ensures that moving a tripod will move the image the same way no matter what direction you're moving it in.
Already done in the new version, hopefully a new video coming soon
I just assembled mine a few days ago and also had that weird part of the keyboard overlay. I ended up using it instead of the translucent piece for the power switch, but there is a green power led right on the other side so I think I’ll switch it. BTW, these are popping up on eBay for those that don’t want to wait 3 months to get one.
thx for the video! does the official site give you the option to choose between the CM4 models?
hi wazzap, quick question. Whats the porpuse of this device for average user?
Does the fixed shutter speed and aperture on this camera enough to capture light through the 720nm filter ? Is there any compensation needed on processing the film ?
after u place order u need wait around 90 days to get your package😅😅😅
This is insane, thank you so much for sharing!!! I am trying to print the lens adapter but the 3D printing places, they all tell me tere are some parts that are too thin. How did you manage to print it? Thank you so much again!!!
How is battery life?
Haven’t done stress testing but standby/powered off has been minimal discharge. After a few weeks of light use just dropped below 80%
Nice thank you
Could you test Ubuntu on this? I'd be interested to see if the mouse and keyboard work out of the box or if there are hoops to jump through.
I tried installing dragonos (base is Ubuntu) but not even the screen came up automatically so there probably is some drivers to work out. maybe clockworkpi has some install instructions for setting up other os’s but I couldn’t find anything when I was testing.
Scratch that, actually was just looking at the schematics and it should just be connected over usb the keyboard has its own microcontroller and firmware you shouldn’t need to do anything for that so it was probably just the screen config
Looks really cool! How's the battery life? Are you willing to share the files? Would love to print my own
@@teaandtechtime Awesome thank you so much!
Hi man, Is there a way to access the RPI GPIO ports, even a few of them?! I can't find if that option exists, it's a big minus if that doesn't exist...
This should work with the 8gb boards too right? Just swap them out? I was reading abt different firmware they have for it but idk if it would just plug in play w a different board.
I paid for the device on October 28, 20-22 and to date I have not received it. I am very dissatisfied with the shop Order No. 19877
Incredible project, I would love to see an update video! Great picture examples as well.
Working on a v2, video may be a while out though haha
