Hardware


Hey, where is all the old stuff?

I finally deleted that all.
As far as I can guess, no one will program a PIC via a parallel port in 2017 :-)

HP-41 Bat

An HP-41, USB chargeable battery replacement with old mobile phone- or NiMH-batteries. Contains completely 3D printable mechanics.


QaDchips

Quick and dirty chips. Another prototype solution.


6mmm/s

A kinetic energy meter (sometimes referred to as "chrono") for pea, foam dart or airsoft toys.
(Although this is not a toy... (*1*)) *WHAMM!*


Paramike

A printable, parabolic microphone for kids and geeks.
((*1*) THIS is a toy =)


chipKIT-Max32-Shield

Just a bare shield for Digilent's chipKIT-Max32.


MetalEars

Headphone amplifier #19, with the right, brutal punch towards the low end.
A real metal edition \m/


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 Parallax Propeller 1 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, maybe. 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 "never finished" 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. Created for operation with 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 (aka. 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!


LiPoPlu

Lithium Polymere Plus. A step up regulator to power DLG/SAL-type model-planes from a single lipo cell. Futaba 2.4GHz don't like voltages below 3.6V...


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...


FoTim (PhoTim)

A simple, 2ch digital light timer, built for darkroom photo development.
