This DIY sous vide cooker was made by my friend Markus. He built it for about 1/10 of the price of the commercial cookers. And it made some really good chicken =) [youtube http://www.youtube.com/watch?v=dYwPwD8Ptqw?rel=0&w=640&h=360] A sous vide cooker is a machine for cooking food using a temperature controlled bath. You can take whatever you want […]
This digital stopwatch circuit is a circuit I built for testing some 7-segment displays. It consists of four displays that I control using a microcontroller. The microcontroller counts and makes sure the correct LED segments on each display is lit up. Check out the video below to see how I built it.
This LDR circuit diagram shows how you can make a light detector. An LDR or “Light Dependent Resistor” is a resistor where the resistance decreases with the strength of the light. Here is the schematic for the circuit:
This is a timer project I recently made. I am really into productivity techniques and I think using the Pomodoro technique is a nice way of working when you need to be productive. You work hard for 25 minutes, then take a 5 minute break. Also, I have found that the sound of a gong […]
This is an electronics project of mine. It’s a 1937 Philips radio modified into a docking station. The reason I did it was because I had this old Philips radio laying around. And I couldn’t use it because it only had an AM receiver. So, I thought it would be cool to make it into […]
I have been looking for a good stereo amplifier circuit diagram for a long time. I am not a HiFi geek, I just wanted to build a simple stereo amplifier that could drive some speakers for my desktop computer. All the schematic diagrams that I could find seemed to involve lots of hard-to-find components or […]
Here is a really cool and huuuge recycling machine we built for a music festival in 2010. It is an interactive recycling station. The idea was to make recycling fun. When you put garbage in it, the machine detects it and moves the ball on the left side one step up. When the ball has […]
There are so many cool things you can make with mini radar circuits. I thought I’d share some examples from my time in the radar business. Then end with a few examples of where you can get a hold of a radar circuit. Just to be clear: A radar is a sensor that uses electromagnetic […]
The story of how I made a prototype circuit board of a circuit that would notify me of plants that need water.
The story about how I discovered the flashing light circuit.
