My DIY Bluetooth Headphones
I made this thing that converts ordinary headphones into Bluetooth headphones. My laptop and phone both have Bluetooth so this will work great with them.
Nehebkau, Laptop Controlled Keyboard and Mouse
I got my Raspberry Pi. I do not have an ethernet connection or Wifi dongle available, or an extra keyboard. I don’t have any Bluetooth either. I needed a substitute keyboard to use the Raspberry Pi.
For fun, I designed a little USB device, actually it has two USB devices on a small board in the shape of a stick. Two USB capable microcontrollers are on this circuit. One will connect to the Raspberry Pi, and behave like a keyboard and mouse. The other will connect to my laptop. My laptop will run software that captures keystrokes and mouse events. The laptop will tell the microcontroller what to do, so when I press a key on my laptop, the Raspberry Pi thinks the same key is pressed. (and the same with the mouse)
Our Fourth Year Design Project: ARUCI
We turned my phone into a universal remote that uses augmented reality. We can track the location of objects and identify them in real time, so we can overlay an icon representing the object on the video shown on the touchscreen. Simply click on the object to interact with it. It’s all wireless, no base station required.
Actual video is 1080p, I recommend you view it full screen.

Our group did circuit and PCB design, we did the soldering, we designed the phone casing, we designed all the IR and RF protocols, we wrote our own firmware and Android app.
Hack a Toaster Oven for Reflow Soldering
As I get more serious into my electronics hobby, I need to work with more SMD components. Some component packages are very difficult or impossible to solder with a traditional soldering iron. To solve this problem, I decided to hack a toaster oven to become a reflow soldering oven.
Other Old Small Projects
Here are some other old small projects. These are probably from my high school days. Some are from my university days. I’ve collected them all onto this one post when I moved my website.
