“Although we have been having fun making things on our desks or work benches, it is time to slowly enter the real world and hack something up. The other day I was in a variety store to buy some glue, and happened across a very cheap remote-control car. After noticing it had full directional control (left, right, forwards and backwards) it occured to me that we could control it with an arduino.”

“Here is the first version of a Braitenberg vehicle, powered with two RC-Servos and an Arduino as its brain. Best of all, it needs no soldering, drilling or hot glue. And if you’ve played already with Arduinos, there is a good chance, that you have already most of the needed parts at home..”

“For my next project, I will need to know the relative position of a moving (<10cm/s) object above (+/- 10 cm ) a surface (flat, but of any quality). After playing with accelerometers, I realized it won’t work (damn you, gravity) so I took the other option I thought of: an optical mouse.”

“Building a self-balancing robot is one of those things that every hobbyist and engineer want to do. But there are a few hurdles for a lot of people. There is the theory on the one hand and then there is the mechanics on the other. In this and the next few posts, I will show you a self-balancing robot I recently built and will explain in details on some of the most important aspects.”

“Using an FPGA to replicate no longer available components on the Sound and CPU Boards in a WPC-DCS Pinball Machine.
These include the two ASICs and PAL.”

“I was curious about PS/2 interfacing to an FPGA, a quick look about the web and I found the VHDL Keyboard Input tutorial. I used the guts of the interface handling from the example design with a few minor mods to display the last 16 scancodes on the VGA monitor, along with HEX and binary representation of those codes.”

“As USB keyboards were an area untouched, I decided to make a small USB HID keyboard device that types a password stored in EEPROM every time it’s attached. A new password can be generated just by tabbing CAPS LOCK a few times.”
