"Computron" AM Radio to Bluetooth Speaker

I bought this little AM radio a few years ago intending to turn it into a Bluetooth speaker. I think they are from the 1970's or 80's.

I used a super simple circuit, just a DW-CT14+ Bluetooth amp and a now discontinued SparkFun Power Cell. The batter can also be driven using this Icstation TP4056. I also 3D printed a little mount in there to keep the USB port steady.

3D Printed iPad Mini Suction Mount

I made this because my other airplane has a 1" ball built in to the dash, so I could share parts of my RAM suction mount between airplanes. This brings the iPad quite close to you in portrait orientation so it's good for IFR.

I'm studying for my instrument rating. I made this tool to help me study which entries to use into holding patterns.

Battery-powered Wii sensor bar for projector screen

Just a couple of infrared LEDs, a red LED to show it's on, a battery pack and a 3d printed mount. Used a 10 ohm resistor on the infrared LEDs, so it should hold a charge for about 15 hours.

Election Reminders Alexa Skill

If the link doesn’t work, just search for “Election Reminders” in the Skill Store in the Alexa app.

The project is open source on Github:
