sounds like you induced an open circuit somewhere in the wiring harness during the assembly process. You'll need to trace the 12V from source through switches to loads to see where it can't get through. Are there any fusible links, they act like fuses but aren't always obvious. Check ground as well ...

Great opportunity for 3D printed case. Bigger learning curve and probably still more than $40 though

Do you mean like the pencil style enclosure, The exact enclosure style you are picturing in your head may indeed be unobtainable but if you broaden your search to the larger offshore enclosure manufacturers, you might find something useful. The "Style-case" line from OKW seems like it coul...

Do you mean like AR or VR type apps? Move the screen around and view the 3D model? Interesting but synching graphics to the accelerometer output is way over my head. r-Pi with good graphics on board already seems like the best platform to start with. Sounds like you need more than just a uController...

Need more clues about how the module failed that caused you to replace it. An easy check is to use the diode check or resistance range on a DMM and check each pin with respect to the ground and/or VDD pins to look for shorts or opens that are not on the good unit. If you find that, it indicates an E...

I haven't dug into the meat of your specific application but the crux of level shifting comes from analysis of the DC specifications part of the datasheet. In particular, you need to verify that the output logic levels from the first stage are compatible with the input logic levels of the second sta...

I suppose you are looking at the current path R6 thru D1 thru pin 7 to pin 1 of U2 to ground. Since this is used as a comparator, we can assume it is either fully on or off and not in any active region Since the CE configuration acts more like a switch it kind of acts like an Inverter. When the tran...

The MPU6050 chip and similar chips are available on a module with interface PCB for Arduino from Adafruit and sparkfun from various sellers so I would say integrating accelerometers like this one with most uControllers should be possible, especially if you can find a code library and use it out of t...

search engine on "BME280 forum" finds several different forums with active or recent discussions

I've only had to add load resistors to the turn signals because the flasher relay requires a minimum current to run. That resulted in variable flash rates under different load situations so I found a solid state flasher relay and replaced that in my fuse box and now it works with or without the ball...

Hi Bob, I saw your email, not sure how to reply back that way. I don't write firmware, My perspective is more from a general device testing perspective but that gets me looking at a wide range of datasheets along the way and experience with DC characterization on these parts. Are you using the TSSOP...

If you can attach to it with your programmer then you are probably addressing the device properly. I suppose if the programmer expects a certain size and if its not, it might report that as bad blocks but I'd think modern programmers are smarter than that. I'm not sure what the AAT suffix means but ...

Heat treating while a science, you need to know your starting material and have control over the process to make it predictable. https://materion.com/-/media/files/alloy/tech-briefs/at0015-0311---tech-briefs---heat-treating-copper-beryllium-parts.pdf According to this I would guess you are starting ...

the material of choice for electrical contacts is BeCu with gold plating. The Berrillium copper alloy is harder than pure copper and can be machined or stamped into shape and it will retain that shape and can be heat treated for other properties like spring tension. The gold plating passivates the s...

"from what I can see though, there is NOT enough time spent on theory, and that makes the hands-on activities simple rote behaviors with little understanding." That's not surprising, schools have to cater to the least common denominator (the barely average student) in many cases. The objec...
