If you ever wanted to connect your microcontroller project to a VGA monitor this AVR Microcontroller VGA Output project by LucidScience will contain lots of great information. The bare bones part of the project is very interesting to see how little is needed to interface with VGA. A free port and a few resistors and diodes is all that was needed. To generate better quality images read further into the
YourITronics has a good article on making a Constant Current Source using a Texas Instruments TPS54232 chip.The TSP 54232 is a flexible little chip but you will need to get out the fine pitch soldering iron tip and cut down on the coffee since it is only available in a surface mount package. There is an interesting DIY thermal via system that is used on the board to allow the
Felipe La Rotta from Engallamientos de La Rotta has built a number of cool DIY projects, this DIY Bench Power Supply is one of my favorites. Everyone who is tinkers with electronics will eventually need to progress from a battery as a power supply to a plug in wall wart then eventually to variable supply. This DIY supply quite a good variable supply since it is based on a computer
Looking for a DIY solution to do Home Automation on a budget? Have a look at this Home Automation system that uses a cheap router to interface your in home items with the outside world using your network. Of course by outside world this includes you using your cell phone while sitting on the couch to turn on the porch light for your wife who is coming home with the
It is sometimes fun to think of a cool problem and come up with an electronic solution. Have a look at this project that Matt Meerian from Home Brew Electronics put together, it is a way to Shoot a Bullet through a Spinning Propeller Blade. This was a common problem years ago when planes needed to have a forward mounted gun shoot through a center propeller. Matt thought it would
Check out the latest Ben Heck Show where Ben makes converts a cheap laptop into an airplane friendly laptop. This is to prevent the guy sitting in front of you from tilting your screen when they lean their chair back. After the hack the screen is able to be tilted up and over the keyboard giving you tons of clearance between you and the objects in front of you. Only
Stanislav Ponomarev has been working hard with his NerdKit Microcontroller. He developed an impressive RGB LED Tetris Game. I think this version is probably more fun than the original version. 🙂 I could just imagine scaling this up and playing it on the side of an apartment building with each window acting as a pixel of the game. Stanislav will send in the code and schematics as soon as they
