  • Since I didn't see it stated: to set the charge current, you connect the resistor between the two PROG holes. (I think there's no need to remove the existing 1K resistor if you're putting a smaller one on, since electricity uses the path of least resistance.) You don't have to try to solder on another SMD resistor by hand, phew!

  • Thanks, but I wasn't really looking for help, just remarking that it doesn't quite function how I expected.

    I've also found that it consumes ~20mA, rather than the 9mA the datasheet describes...

  • I was having a lot of trouble getting this to work at first. I could send text through it from phone to PC (connected by UART) but not receive anything back; not from the PC or the AT command responses.

    Eventually I realized this was just because the bluetooth terminal app I was using buffers until it receives a line break, but the module doesn't send them after AT commands. So I can issue an AT command from the phone, but have to then send the \r\n from the PC so that the app will actually show the AT response it received.

    What's curious though is that the datasheet seems to imply that AT commands are only accepted from UART, not from wireless, but in my case, it seems to be the other way around; no response to AT commands over UART, only from my phone. Also, sending just "AT" doesn't terminate the connection, but returns OK as if not connected. I wonder if these modules somehow have mixed up which end is which?

  • So, I'm still seeing a warning on the battery pages. Are you able to ship batteries to Canada?

  • Does this come with the supercapacitor on board? I can't see the photos.

  • We could harness the waste heat to power the miner itself AND keep it cool!

    Although I think Bernoulli, Joule, et al might have something to say about that idea. ;-)

    Still, I always thought using a computer's waste heat to generate some electricity (while also cooling the computer) seemed like a better idea than just using a heat sink and fans to heat the room, even if the efficiency is limited...

  • Yeah, this isn't very helpful. From the photos I can't even tell if this wire is coated with plastic or something else or if it's bare wire which happens to be red. How flexible is it? The description doesn't tell me anything either except that it's flexible and 25'.

No public wish lists :(
