This one is a very simple but cool project, something that I would recommend to anyone who is interested into DIY electronics, gadgets and learning new stuff in general. It is definitely one of those projects that don’t require too much time but you can learn a lot by making it and also earn a lot of credit by sharing it with your friends and family.
Below you can see a final product. It’s a heart shaped, touch sensitive, keychain for your loved ones. On the front side there is a smiley face drawing that has eyes and mouth. Eyes have two red LEDs that will start to pulse once you touch the keychain or place you finger on the smiley face (see it in action below) Continue reading “Make your own Heart Keychain”

Recently I was in need for a simple device that will draw reasonably precise amount of current from my power supply unit under test and read the voltage and current draw. There are a lot of schematics and products that do just that, or you can do this just with two digital multimeters, op-amp, mosfet and potentiometer and that will probably work just fine, but I wanted to create my own version and try to improve it. 🙂 Continue reading “Power Supply Active Load Tester – Open Source Open Hardware project”
