  • Most of the pharmacies near me have them (I guess some hearing aids use AAAA?). Horrendously expensive, though. Had to look for some because my “active” tablet stylus uses them (it’s a Dell). The Surface Pro 4 stylus uses them too.

  • Please please please make a version of this with integrated battery management! This would be the “Teensy Fio” I’ve been looking for. The poor 8MHz ATmega on the Fio just can’t keep up with what I’m trying to do.

    Very happy to see mxgxw’s design. Will have to order one and brush up on my SMT soldering…

  • If the surprise is “The (Shadowy) return of the RedBot”, Shadow’s assembly guide gave the game away :)

  • The Teensy LC doesn’t have the spots on the underside of the board to attach the 32kHz crystal - only the Teensy 3 does.

  • That’s 3. Lets compare against… Sparkfun, Adafruit, Jameco, Maker Shed, Pi Hut, Arrow, multiple sellers on Amazon, my local computer store… Most vendors sell above $35, just like most did with the original Pi. See the post above from M-Short as to why it’s basically impossible for anybody but a bulk distributor to sell for $35.

  • Where is ‘everywhere else’? The only place I’ve found them at $35 is MCM. Most places are charging even more than this. Newark/Element14 doesn’t count, since they just send you to MCM.

  • I see these servos have a 4th wire which, from reading the code, is hooked to an analog pin. These must be “analog feedback” servos. In this case, the 4th wire is connected to the internal feedback pot, allowing you to read the servo’s position with analogRead.

  • I love these! I have seriously bought about a dozen of the Adafruit ones. They come in handy everywhere, especially in tight project spaces. Lots of household and travel uses for them too. If you have one of those mega multiport USB chargers (like the popular Anker ones), short cables are great for reducing the clutter around them. Faster charging too - less cable, less volt drop.

  • But, but… where is BLE Mate 1? What have you done with her!?!

  • That only covers the regular (non-Pro) Trinket, unfortunately… The Pro Trinket guide really doesn’t have a good pinout summary. I guess they expect you to know Arduino pin functions by the numbers, so to speak :)

No public wish lists :(
