"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.

Holding Pattern Entry Quiz

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

I created an Alexa skill to remind users when to register and vote in elections. The skill will create reminders that are specific to the user’s state. The skill is available here:

https://alexa.amazon.com/spa/index.html#skills/dp/B083QJTML8/?ref=skill_dsk_skb_sr_0&qid=1578685256

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:

Data was collected from the official EAC website: https://www.eac.gov/voters/register-and-vote-in-your-state#tabs-2

Hi, Mom! A low-res photo frame

I made this for my mom's birthday. It displays low-res pictures that I can update over the internet.

I figured out that you can melt PLA with a soldering iron on low heat, which I used to affix the circuitry to the base.
