Am I the only one who is wondering why someone doesn’t come out with a watch band (would like one for my Pebble!) with a snap connector for ESD? Or the only one with a tan line in the summer from...

Grody on COM-09689 - Optical Dust Sensor - GP2Y1010AU0F

How practical would it be to use this to detect smoke (like, as part of a fire protection system)? The datasheet recommends that I don’t use it for this, but do they mean that in a “this device is...

Tomotron on PRT-10161 - USB LiPoly Charger - Single Cell

It’s a bit expensive for what it is but mine worked… for a while. First the LED burnt out fairly quickly. Then the MCP73831T brain smoked and blew itself right off the board. Bummer.

Customer #284290 on LCD-00256 - Basic 20x4 Character LCD - Black on Green 5V

The “solution” I came up with was simply to use the cursor positioning feature to write to the lines I wanted. Since you’re writing strings anyway, it’s not terribly difficult to do. If you’re making a...

DanielTT on COM-11647 - OpenSegment Serial Display - Tall (Blue)

Perfect timing! I’ve been using the smaller version of these, loaded with some custom firmware, as airsoft spawn timers. They work great, but the displays needed to be a little bigger. I’ve just been...

jti_ on LCD-11075 - Serial TFT LCD 4.3" with Touchscreen - uLCD43

c-scott on BOB-09598 - MIDI Breakout

Hm, looks right to me. Maybe your Arduino is slightly off? (Then again, I’m using Sparkfun’s arduino breakout footprints on all my stuff, so it’s not surprising that it matches this board. But I find...

shardbearer on COM-11644 - OpenSegment Serial Display - Tall (Red)
