Hallo, Willkommen auf meiner Seite!

Was ich so mache:

• Ich bastele momentan an Robotern, siehe unten
• Ich programmiere manchmal Animationen für die Borgs
• Alle farbigen Borgs haben Plasmaeffekte von mir :-)
• Ich habe an der rfm12lib, dem rfm12usb und dem rfm12 Bootloader mitgebastelt.. ausserdem benutze ich rfm12s in meinen Projekten
• Ich bringe Design in das Wiki!
• Ich habe schon mal ein Kind gelötet...

Rechts sieht man mein aktuelles Roboterprojekt, den Shr0dBot.

Vielen Dank an Mati für das Foto!

Das habe ich mal gemalt, als ich die bunte Kreide fand.

==== MOTORCTRL MISC STUFF ====

* Encoder IR-Diodes 1k ?? (re-evaluate)
* How to connect phototransistors? I can remeber they had 1k resistors on em. (See on orig. board)
* Use 1/8th Voltage divider (14.4 / 8 = 1.6V -> 12 cells * 1.5V max = 18V -> 18/8 = 2,25V)
* Use logic level fets for vacuum and brush motor turnon/off
* Reverse engineer loader circuit, reuse relais if it could cut loader power
* Use L6202 motor driver ICs

==== MAINBOARD SPECS ====

* Use the fat 128k flash / 16k ram 40pin DIP Atmega
* Probably use a switched power supply -> ask peter for that chip
* Think of creative use for the big fat atmel
* Use rfm12
