Very compact the way you sandwich the boards together! I take it the low profile female headers used on the USB HS402 pcb will not provide enough clearance.

Hi Denis, Great project Denis. Will build one myself using your instructions. Confused as to what is the difference between version 2 or 3 of the PCB. Which should I order to follow your build (I know you used V2) but perhaps V3 is an improvement ??
I invite you to join us on TELEGRAM HScope LOUNGE: t.me/hscope much better place to discuss the v2.0 and v3.0 differences and lots of tips and advice before starting to order components...I will greet you there George:)
@@theGADGETSplaylist Thanks Denis, Had trouble getting into Telegram before (didn't like my Australian mobile number) but just got it to work using your link.
Hello Denis and Martin, my bits have just arrived and i am assembling my version of the board etc. Just measured the current consumption of the board at 16 mA @ 5 volts and at 3.3 volts it is also 16 mA as supplied from the 3.3 volt pin on the 4 pin header socket at one end of the stm32411 board. It seems that that the voltage regulator on the board can be "backfed" from the 3.3 volt header pin connection without consuming any more current. The blue led/pushbutton on the board is happy with the 3.3 volt supply as well indicating the test software is running ok. Can i propose to supply the board for option 2 and 3 with the respective external regulators for that option and leave the little choke near the micro in place? This would make it easier to complete the project for some of the builders. Or is there a special reason to remove the choke?
Technical questions such as these are best answered in the TELEGRAM HScope Group... I invite you to join us where Martin or others can discuss this with you Max: t.me/hscope
I've been trying to piece this together on digi key but their are to many options for the components. is there a shared cart somewhere i can get these from or more specific component list. for example what voltage should the capacitors be.
there is a BOM on Martin's GitHib...link is in video description box...I sourced everything on Aliexpress... if you're going to build this Walter. I highly recommend you look us up on the Telegram platform...here is a link: t.me/hscope Denis

you are describing a Faraday Cage which was implemented on HS102 (GADGETS#62 @ 3 minute mark) that scope is USB like your PICO and lent itself to this but the HS402 featured here is WiFi and the built-in antenna of the ESP32 chip would likely be impaired by a metal shielding
@@theGADGETSplaylist yes its all true but you can shield and use external antenna I have a pico 2205 old one And saw that the new Versions came with metal shield around the board Só i wrapped the plastic inside and now im in microvolts range maybe because was next to tv but now im happy Thx for answering
@@alexluz7023 the 30pin ESP32 boards that this build uses does not come with external antenna option nor does it need it others have tried the ESP32E and found external antenna orientation relative to the circuit to be very temperamental causing more issues rather than solving them all of this stuff gets experimented and discussed at length in our HScope Telegram Group, Alex:)
I see that the MQ sensor values are influenced by humidity and to a lesser extent temperature. This might explain your "false positive" readings at steamy hot engine temps. Do you have any idea of the response times of these sensors?
you are absolutely right about the moisture...it's a consideration... I don't have the electronic response times at my fingertips...nor would they matter...the real response time is determined by how long it take for sample to reach chamber...I've modified the water separator since the video...check out images in download folder...and that has sped things up...
@@theGADGETSplaylist I saw a temperature correction formula in the datasheet but nothing for moisture otherwise one could add a humidity and temp sensor to the sampling chamber and correct in software if one really wanted exact measurements! Actually, I wonder if a humidity sensor would be useful for detecting water vapor in the crankcase or exhaust in cases of headgasket leaks of coolant? The alcohol in gasoline might throw exhaust measurements for a loop though. My interest in response times is motivated by a curiosity of whether the system could be used to detect leaks in the intake or exhaust systems? One could use smoke or some hydrocarbon spray as a tracer and sniff around with a air sampling hose.
@@TheDerekeder those MQ-x sensors and analog and digital outputs... Most ARDUINO projects you see are using the digital output combined with elaborate "sketches" and targeted at air quality measurements. I've used the analog output which is oscilloscope friendly and needs no code/sketches...it is for detecting the presence of hydrocarbons or CO2...no corrections/compensations...
