    It looks like you should NOT have JP1 and JP2 BOTH with a solder glob on them, else you’ll short out one of your source Jacks. If you have JP1 shorted, the barrel jack already populated is good to go, but the other connection doesn’t go anywhere. If you have JP2 shorted, you are essentially using the two inputs in SERIES. Is this correct based on the schematic?

    A WORD OF WARNING: 3M made something like this many many years ago that worked very well for elevating and positioning boards that needed to be isolated from vibration. This is a lot thinner so it doesn’t do that very well BUT that material and others like it seem to break down into a…. gooo is the only way to describe it… that will coat and make sticky EVERYTHING it touches and transfer instantly to any surface. Requires a lot of contact cleaner or Goof-Off to get rid of. This “goo” process takes a long time (decades in some cases), so remember that when Future You has to do something with the PCB Today You is building into an enclosure.

    In an attempt to recreate the Electric Slide, he merely demonstrated the effectiveness of the Actobotics A,B,C,D,E,F, AND G linear slide frames… simultaneously… and at speed. The conference table was impressed… and scratched… and gouged… The cleanup crew, however, was not moved.

    Are there tags on the products that are/work with them? Even if you couldn’t do a straight up title search for them, if there was a “Works with” metadata tag of some sort, searching would still be possible and could lead to a catalog-like page for these. This would also apply for Pi-specific stuff, ‘Duino specific stuff, GPS-module-specific stuff, etc. I know you guys maintain a “related products” tag in your DB’s, I’ve seen them mentioned in comments before, but are those tags visible to the users? (I work in SharePoint, Search is one of my many job requirements :P )

    Or separate heat zones like many cars have. Butt / Butt + Back / Back / Off

    removing the connectors to the seats can sometimes trip the SRS computers and require you to do a reset procedure through the ODBII connection, it depends on the model and where the pre-tensionors are. That’s ESP true with a car that has airbags in the seats. In most cases, if the connector goes to an airbag, there’s a little shorting wire in the connector that drops in on the airbag side to prevent static discharge and erroneous signals when they are unplugged.

    When I saw the thumbnail for the video, I saw the reflection on the insulation for the heating pad and it looked like little flames, or at least that’s what my brain immediately went to :D

    The charging voltages people have mentioned in foreign cars, my Honda also spikes up to 15.5 when I rev the engine. It went to 18 when the regulator opened up and the alternator nearly fried itself. It tripped my SRS computer, and I had to do a reset procedure through the OBDII connector.

    Thermostat, YES! Or thermal fuse! Running them in series (in two parallel groups), good idea, that makes for safe failure if one shorts (but not if two short in the same string).

    Also, cement those pads to a fabric or rubber (neoprene?) that can handle the heat, AND keep them from distorting from getting in and out of your car! Your movements could, over time, grind up the heat tape or the connections to the wires and then you’ll get a short for sure.

    Otherwise… you’ve got me thinking… ;)

No public wish lists :(
