I’m a pico 4425 user and have every accessory for it but I’m also in the process of emailing them to order their pressure pulse sensor and a few of their ignition coil pickups.

The only downfall is you can’t just order off of the site and have to go back and forth over email to get it done. Very slow process so don’t be in a hurry
I am aware and agree with all the points you raised, John. ROTKEE threw in a PDS pulse transducer in the box when they shipped me the PS16. I'll try to find the time and the right application to showcase it.

HScope supports a number of commercial oscilloscopes...but if you mean building HS402, yes you should give it a shot if you've done a bit of SMD work in the past. If not, start with easier project and then the HS402. We build these because they're fun to do:)

Those DIY pressure sensors have their range spread over 4 volts. Typical of many 5v reference sensors. This ROTKEE takes that up a notch and spreads it over a full 5v The FLUKE PV350 spreads its 350 PSI over 350mV...useless...and expensive!

In the middle of hs402 build, having trouble flashing stm32f411 black pill. Samsung tab A tablet won't flash apparently neither will my Samsung phone. So tried emulating android on laptop but stm utils wouldn't recognize the connection. So now I'm trying to install the needed components on my raspberry pi. Is there any way to just flash with laptop? Low budget scope isn't so low budget if I need to buy a new phone or something lol so exploring all my existing options before upgrading any devices. Was thinking of just buying the pico 2400 series scope but really like the Hscope app and layout plus already purchased the automotive version lol
If you like the HScope APP, Jedi and are considering purchasing an oscilloscope then look at the LOTO OSC482, OSCA02 (same as OSC2002) that I've reviewed on the channel.

remember , this rotkee is a ukranian company and can be owned by russians cause the population is mixed and the current situation tears families apart. All the massive EU investments by citizens are at stake and the EU countries have asked their citizens to leave the Ukraine instantly. They can be tomorrow on an american embargo list once they are recogniced as russian, cause now the Ukraine population will seek their compensation and put pressure on the russians among them, well russian roots, but ukraine citizens with ukrains passports like in the baltic states. They were cheap due to cheap labor there but things will evolve as the supply issues have grown in the past few weeks cause the ukraine companies benefitted in the past from strong relations to the russian suppliers and all that is at stake cause they had not moved away from the cheap russian supply chain since the 2014 occupation of the chrimean peninsulla. pretty difficult to get stuff cause I guess the embargo have started which means they have to proof that their products are made in ukraine and do not rely on russian supplies. Ukraine to EU is a stronger border than Mexiko to USA, cause that is the outside border of the EU.

Hi, I've discovered your videos recently and, although I find everything I've seen so far very interesting, this one is a game changer for me. I've been a dealership tech for about 18 years and am fed up. I'm looking to move to being a self employed mobile diagnostician and well, let's face it, with all the scantools I need to buy, the $6000+ pico or escope kits are kind of prohibitive. When I saw the price of the Rotkee, I started laughing and almost cried. So, I wanted to thank you sincerely for having me made discover this product. Now here's a question. How do you think it compare to the pico? Is it as capable?
comparing the PS16 to PICO WPS500 ...WPS500 has fastest response time but PS16 is adequate and so much affordable...no battery to charge and easy to use... comparing MT PRO to PICO is difficult... ROTKEE MT PRO is not an ordinary USB scope...it connects to laptop through ethernet port...and has other differences... but for $220 and 8 channels it is hard to beat...just make sure you understand those differences before you buy and you'll be ok... they have been experiencing stock issues, so there might be a wait...and their ordering process and communication is not the best...but I think these are honest people and I know members of our HScope group have been ordering successfully from them
if you think you're ok with 2 channels then LOTO OSC482 is only $65...pair that with HScope app on phone/tablet...and 4x attenuator DIY...and you'll have a powerful, portable scope solution...VERY good...but, yes 2 channels
@@theGADGETSplaylist thank you for your fast reply and additional info. Very helpful. I'll be ordering an Rotkee for sure, I'm mean, like you said, at that price, it's hard to go wrong.

Although the math is simple, PICO and HScope take different approaches to PROBE configuration. And, it's the simple things that can be the most dangerous:) With that in mind, I'll provide PICO settings for ROTKEE PS16 For BAR: Y = 3.4 Offset = -1 For PSIG: Y = 49.3 Offset = -14.5 I think these are ok. Let me know if there are issues George... Denis
I think the PSIG numbers are ok but I'm having second thoughts about the BAR numbers. For BAR, please make Offset = 0 (instead of -1 as I originally submitted) And let me know, George:)
@@theGADGETSplaylist Mr denis I already try both formula y x types and the correct is y 3.4 and offset -1 .before try i take a measurement for compression with gauge and it's almost the same values very small difference and I also check with vacuum gauge the same time with ps16 engine running to test the vacuum values.the only difference i see is that the ps16 characteristics 294mv equal 1 atm or bar and if I have the ps16 connected but not plug in in cylinder but on my tool box the value of atm is 325mv and because is small difference i let it as it is I'm not trying to adjust in picoscope probe setup because I don't know if the weather is changing a little the values or the place I am !but for this price and tool I am very happy and satisfied!I hope after few uses still work fine!!thank you very much for your help !!!I wish you every day be happy with a big smile in your face!thank you again!
That is a very nice clean pattern,with the hose temperature affects pattern as the hose is gets hotter you can see pattern change
transducers also get hotter (compressed air, after all)...why tests should be done quickly
Awesome information! Can't wait for my scope to arrive. Engine diagnostics are gonna be a lot quicker!

great time to be alive:)
Nice waveform, it looks a great transducer, I will show this to someone that was asking me about pressure transducers. Cheers

Great video (as usual)!
Good point about the dead space in the hose line. This "capacitance" contributes to the distortion and phase shifts in apparent timing you talked about in a previous video.

ROTKEE threw in a PDS pulse transducer in the box when they shipped me the PS16. I'll try to find the time and the right application to showcase it.

my advice is know what you want...including the accessories...add to cart, even if says available in 3-4 days...proceed to their checkout...pay with 1 of the 4 available options...
really good stuff at really good prices...small business this run by honest, hard working people, in my opinion...
good luck with your purchase:)
How do I buy them hear in the states.
You can only buy directly from the ROTKEE website. Link in the description box.
Check the items on the order form and you'll be contacted by e-mail confirming pricing and shipping options.
They do not accept PayPal
Hope this helps, Daniel
I'll be releasing a video shortly on the ROTKEE PDS Pressure Transducer. You may also be very interested in that...
wow nice
Thanks, Dan:)
Hello sir!I buy a ps16 and I have the picoscope and I want to add this probe and I can't find anything on the web about the scaling for this probe.is this correct ?0 mv equal to 30 inHg
294 mv equal to atmosphere (1 bar)
588 mv equal to 2 bar
882 mv equal to 3 bar
1.176 mv equal to 4 bar
1.470 mv equal to 5 bar
1.764 mv equal to 6 bar
2.058 mv equal to 7 bar
2.352 mv equal to 8 bar
2.646 mv equal to 9 bar
2.940 mv equal to 10 bar
3.234 mv equal to 11 bar
3.528 mv equal to 12 bar
3.822 mv equal to 13 bar
4.116 mv equal to 14 bar
4.410 mv equal to 15 bar
4.704 mv equal to 16 bar
4.998 mv equal to 17 bar or i have to step-down the bar like this to take correct values at the waveform as a pressure gauge
0 mv equal to 30 inHg
294 mv equal to atmosphere
588 mv equal to 1 bar
882 mv equal to 2 bar
1.176 mv equal to 3 bar

4.704 mv equal to 15 bar
4.998 mv equal to 16 bar
Thank you very much.keep make your gadgets you help us very much!Best regards!
Although the math is simple, PICO and HScope take different approaches to PROBE configuration. And, it's the simple things that can be the most dangerous:)
With that in mind, I'll provide PICO settings for ROTKEE PS16
For BAR:
Y = 3.4
Offset = -1
For PSIG:
Y = 49.3
Offset = -14.5
I think these are ok. Let me know if there are issues George...

@@theGADGETSplaylist i will try soon this settings and I will inform you!thank you very much for your fast response Mr denis!
I think the PSIG numbers are ok but I'm having second thoughts about the BAR numbers.
For BAR, please make Offset = 0 (instead of -1 as I originally submitted)
And let me know, George:)
@@theGADGETSplaylist yes Mr denis i set 0 the offset and I will try soon. Thank you very much for your help!
@@theGADGETSplaylist Mr denis I already try both formula y x types and the correct is y 3.4 and offset -1 .before try i take a measurement for compression with gauge and it's almost the same values very small difference and I also check with vacuum gauge the same time with ps16 engine running to test the vacuum values.the only difference i see is that the ps16 characteristics 294mv equal 1 atm or bar and if I have the ps16 connected but not plug in in cylinder but on my tool box the value of atm is 325mv and because is small difference i let it as it is I'm not trying to adjust in picoscope probe setup because I don't know if the weather is changing a little the values or the place I am !but for this price and tool I am very happy and satisfied!I hope after few uses still work fine!!thank you very much for your help !!!I wish you every day be happy with a big smile in your face!thank you again!
