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...
• Manchmal helfe ich bei der Labortage Orga

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

==== MOTORCTRL ATMEGA8 PIN CONFIGURATION ====

Names in () are or were planned.
Pins marked with [in] are inputs, whilst the ones marked with [out] are outputs.
All other pins make use of their respective special function(s).

==== 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
* Motor current:
** Blocked motor draws max. ~800mA
** Normal operation ~350mA
** 0.1 ohm current sense resistors
** Max ~80mV sense voltage
** ~35mV in normal operation
** 25 times amplification to use with adc @ 2.56V internal reference
** Use lm358 opamp
* What do the two diodes @ current sense / gnd do?
* atmega input with pullup -> encoder phototransistors -> 4,7k -> gnd

They used:
* L289 for motor control
* 14.4V motor power
* LM2565T switching power supply for logic
* IR-led + phototransistor for encoders
** 14.4V+1K for leds
** ~2.3V / 11mA for leds 
** Try 220ohm @ 5V (should be around 12-13mA)
** Phototransistors are pulled up by 10k or something (one has 10k, one has something else)

==== 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

Hansinator's MotorCTRL Board

• Both L6202 are correctly connected to motor and atmega
  • Need a solutin for current sensing

svn notizen

ask sören about broken symlinks in nerdgame gui -> delete, ask alex first
./microcontroller/src-atmel/nerdgames/host/nergames-gui/

someday this needs to be patched to use crc and stuff, as in trunk
./src-atmel/automatization2.0/cand/branch/usb_support/

ask sören about branch -> delete
./src-host/src/cand-ucspi_tcp/config.h:8:#define UART_HOST

ask peter which source is for moodbar (src-atmel/theke or src-atmel/moodbar)

ask madex if winamp plugins may be deleted

bash the sources

# grep for stuff
grep -Hirn UART_HOST . | grep config | grep -v svn > uarthost.txt

# print all files in uarthost.txt (grep output)
for i in $( gawk -F : '{ print $1 }' uarthost.txt ); do echo $i; done

# remove all occurences of uart host define in files
for i in $( gawk -F : '{ print $1 }' uarthost.txt ); do sed -e '/#define UART_HOST/d' < $i > $i.new; done
for i in $( gawk -F : '{ print $1 }' uarthost.txt ); do mv $i.new $i; done

# revert files...
for i in $( gawk -F : '{ print $1 }' uarthost.txt ); do svn revert $i; done
