  • NC - Normally Closed: The signal on the output will be held high (5 V) until it starts a “strobe*” cycle. The output will be brought low (0 V) and back high again for the amount you programmed for a particular coin (ie, five times for a nickle, ten for a dime, twenty-five for a quarter).

    NO - Normally Open: The same as above, but it will be held low. The transition will go from low-high-low.

    *for lack of a better phrase

  • About a year late, but who cares. Product Video

  • “And that’s when the game of Duck Hunt took a turn for the worst.”

  • I found it–hiding in plain sight, of course. I also didn’t notice it was a TLC555. I was thinking of the NE555, which its datasheet implies that 100kHz is the maximum. I won’t be able to test it for a bit because, apparently, I didn’t plug in my o-scope before piling a bunch of stuff where I can’t get to the power strip :P

  • About a year late, but whatever. I read somewhere that these can only put out a hand-full of kHz. I can’t find anything in the datasheet. I’ve been wanting to test one with an o-scope to see what I can get out of it. I’ll edit this post when I finally get off my lazy butt and do it.

  • 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.
