  • Arduino Pro Mini 3.3V x 25: $9 ESP8266 x 25: $6.50 Not sure what the Photon development ecosystem gains me over this setup that I’d pay SF 2X for? Look, I’m not trying to be a downer, I’m just not really seeing the value here, but obviously SF has because they are going all-in with Photon add-on boards, so maybe you can better explain what is so good about it?

  • I just keep thinking that $30-40 a board isn’t going to get very many people into IoT. It’s the same issue Xbee/Zigbee has always had; even the cheapest radios are still too expensive for people to really go nuts with them. For the price of this Photon Redboard I could buy a RaspPi 2B and a wifi dongle! If you want to drive the IoT to a new level, people need $3 radios.

  • “Black Angus Rocket Storm” is the best name I’ve ever seen.

  • What gauge wire can this thing take? Had a problem recently where I ordered a barrel jack connector like this and the stretchy thing on the end was way too small for the wire.

  • What’s the logic (ahem) behind the 1.8V logic level?

  • Are you sure you don’t have the RA and LA electrodes backwards on your chest?

  • :)

  • Sweet! Thanks!

  • Did you add the AD8232 and 3.5mm stereo jack to the SF eagle library?

  • I built the basic picobuck circuit into a device and made it past 60601-1 3rd edition emission and interference testing with zero problems. I mean it was silent. Beautifully silent. If you do your own circuit board, make sure you follow the layout recommendation in the AL8805 data sheet, and put your inductor in the right place.

No public wish lists :(
