Hey, where is all the old stuff?
Due to a complete redesign, as of 6-X/2009, I had to remove most of it.
Just a few, randomly selected projects, so far...
ASkr 6/2009 - 11/2011
 |
chipKIT-Max32-Shield | Just a bare shield for Digilents chipKIT-Max32. |
|---|---|---|
 |
MetalEars | Headphone amplifier #19, with the right, brutal punch towards the low end. A real metal edition ;) |
 |
nMeas(1/f) | A modular kit of hard- and software for noise measurements. We'll start off with the "1/f noise edition". |
 |
UniTHAmp |
It was time for a new, universal lab-fun-amp. Standard design - incredible diversity... |
 |
xPIClog | A simple, but quite versatile and highly configurable 8 channel SD-card data logger. Powered by a PIC18 and SourceBoost. |
 |
MicroPropUnit | MicroPropUnit, just a tiny, standard component Propeller board. |
 |
LTCsourcerer | LTCsourcerer, the Little Tiny Current source for automated uA measurements. |
 |
GrabschKamView | GrabschKamView(Debugger); An analog black and white camera (PAL) capture and variable display helper. |
 |
ExcoLight Color | The exceptionally complicated (and colored) light. A four channel, bus capable LED buck regulator. Color version. |
 |
ExcoLight Basic | The exceptionally complicated light. A bus capable LED buck regulator. Basic version. |
 |
IThreeC | Another updated variant of a galvanic isolation for an I2C bus. Also known as a "Inter-Integrated-Isolated Circuit" (I3C ;-) |
 |
Promp3ller | Oh no! Yet another VS1011e based MP3 and WAV player... Yes, may be. But this one has a Propeller ;) (and soon an ethernet, a Zigbee, a remote control with display and, and, and...) Guess why these pages are called "unfinished" 8) |
 |
FX2LPMini | Just a Cypress USB CY7C68013A MCU (aka "FX2LP") mini breakout board. Reconstruction of the 2005 V1.0 design. |
 |
MiniFTDI (a bad week) |
Just a quickie. FTDI USB<->CMOS-RS232 converter with Propeller reset. Nothing special, except for all the other stuff that happened... |
 |
MiniMess | A tiny, serial, bus-compatible and cascadable measurement interface featuring a 10-bit A/D (autoranging) and an additional D/A converter. Targeted for operation by pocket calculators (HP-48/50) or old Sharp pocket computers. |
 |
H-Bridges | Some H-bridges for DC, stepping and servo motors (and more). |
 |
photo frame "hacks" | DFPs, digital photo frames, provide a cheap LCD/TFT source for your own hardware. Batteries included ;-) |
 |
STM32Mini | A minimal, ready to run ARM Cortex-M3 STM32 board. |
 |
JTAG Scanner (UniPort) |
An update of an older circuit: An universal port interface. Can be used as an universal, bidirectional (bus) interface. Modularized version, up to 48 pins. Also useful for digging deeper into others people hardware ;-) |
 |
LPC0k9PROG (NXT2NXP) |
A Lego NXT based programming tool for LPC900 ICP. pbLua featured! |
 |
Encoder | A Minimal, cheap and reliable quadrature encoder. |
 |
LiPoPlu | Lithium Polymere Plus. A step up regulator to power DLG/SAL-type model-planes from a single lipo cell. Futaba 2.4GHz does not like voltages below 3.6V... |
 |
(Fast) Current Sink | A quick and dirty but still precise current sink up to 6A (150W limit) that operates down to ~0.5V, so it is suitable for discharging NiMH/NiCd cells, too. |
 |
ServoBus | 2 wire powered servo bus. This brings the "drivers" to where they belong: The servos themselves. Minimizes cabling complexity. |
 |
I2C Servo | A minimal, 6 channel, I2C controlled servo controller. |
 |
AUAA2 | Akki's Universal Analog Adaptor V2. Connect your PS2 analog controller to your PC. Full featured, and even more... |
 |
Wii IR sensor | How to interface the Wii IR sensor (I2C). |
 |
MonoAmp | A little, single supply powered audio power amplifier. |
 |
StepBlaster | A tiny 20A stepper motor driver stage (if cabled right ;) |
 |
FoTim (PhoTim) | A simple, 2ch, digital light timer built for darkroom photo development. |
 |
PICprom | A minimal parallel port PIC programmer. |
 |
TransAmp | A case study on DC offset mechanisms for a transimpedance headphone amplifier. |
