MICROCONTROLLER-POWERED rocket introduce CONTROLLER

[Josef Jahn] has published a detailed guide on building a microcontroller-based introduce box. built from an Atmel ATMega168 as well as powered by a 12V rechargable lead gel battery, the introduce box is completely portable as well as includes a number of security features. Going the additional mile on what might essentially be a simple push button launcher, he added three security switches, a sixty second after-launch timer as well as a gorgeous (not to mention rare) PLED screen total with remarkable condition messages. inspect out a video of the launcher in action after the break.
