I made an app-controlled alphabet board (inspired by Stranger Things) as a Christmas gift for my niece. Before I was done I decided I wanted one myself, so I went ahead and made an Instructable so anyone can build one. Enjoy 🙂 light up alphabet board
So it seems I, or rather Project R, won a CrazyFlie 2.0 in a Hackaday contest. (or rather, !) Pretty awesome, huh? I thought so. Thanks HaD! The sucky part? I received it in the mail the day I started my new job, so I had to wait until the evening to put it together and play with it. Pretty fun little doowhackey as it turns out. Which brings me to the other sucky part: Unfortunately my phone is too dumb to drive it, no BTLE, so I have to borrow either my son’s or my wife’s phone to play for now (no, I wasn’t smart enough to add the crazyradio to the order). ...
If the Project R idea was drawn in CAD (Crayola Aided Drafting) then this is Cardboard Aided Manufacturing. Anyway, here’s a prototype of the remote project. cardboard prototype
These have been done and sitting for a couple weeks. Now I’m finally getting around to playing again. Wheel encoder board Two QRD1114 and a 74LS14 to square up the signal. Motor controller Built on a leftover protoboard from Gadget Gangster with an ATMega328 at 16MHz (yes, running as an Arduino) and a Pololu TB6612FNG motor driver. The two wheel encoders go to the interrupt pins. The little surface mount chip still needs its connections soldered up, it’ll be the 3.3v-to-5v I2C translator between this and the BeagleBone Black. ...
Breadboarded wheel encoder. ATMega328 on the left, 74LS14 in the middle, QRD1114 on the right. QRD1114 on a radio shack proto board. So far it seems to work as expected. Guess it’s time to build the second one.
