  • Probably just got too happy with the shift key. We use lower case m for meters.

  • Keep in mind that 10 A is the stall current, which will always be higher than the run current. Testing for a stall condition shouldn’t be too hard (built-in reed switches). I used to have a link to the motors datasheet, but it quit working and I deleted it. The motor has three leads instead of four. I forget the configuration name, but it requires two leads to be used at a time: one tied to Vcc, one to Vdd, and one disconnected altogether. I would need six of these things to be able to run the motor and I was trying to determine what my best option is (mosfet switches or solid state relays or whatever else).

  • Because if you win you can afford to buy more ding and dents.

  • This is now my favorite story on the internet.

  • Would it be okay to send about 10 A at about 12 V through one of these? I’m looking to build a BLDC motor control circuit and 10 A is the stall current of the motor.

  • I did that with a neon (or some type of gas) light. Thankfully not many shards were produced from the bright, beautiful flash. Not too long later I learned about those types of bulbs. I also learned back a long time ago about putting 18 volts into an LED with no resistor.

  • I think I’ve only seen like one or two total. I’ve not actually tried it, but it shouldn’t be that hard (as a proximity sensor). Just set up the detector to drop voltage and use an ADC to test the voltages. You might even be able to get the voltage to fluctuate enough to use a digital input. As for beam breaking, you can at smaller distances with no filtering (two or three inches).

  • It finally arrived today. I made an imgur album.

  • I suggest making the videos longer and explain what data you actually get from the sensors: what do you expect from the altitude/pressure/temperature breakout? Analogue voltage? What are you supposed to do with the values you read? Do you just print the value and add a unit or is there math involved?
