Electronic DIY Projects from Dago
"Here’s a quick project I made in couple days or so. It is a push-pull step-down laser diode driver based on LT1683 SMPS controller chip from Linear Technology."
Switchmode laser diode driver based on LT1683
"I’ve been thinking about making a temperature logger for my room and my computer, I set on using DS18S20 sensors from Maxim because they’re common, cheap and overally pretty ideal. My computer is so new that it does not have a serial port "
"I also built a humidity sensor to my 1-wire network from a DS2438 chip and a HIH4000 humidity sensor."

Among others they also have Amplifier Design, Antenna and Filter Designer AF and RF and Basic Electronics Tutors.
Homebrew Projects - Laboratory of Changpuak
A Geiger–Müller tube consists of a tube filled with a low-pressure (~0.1 Atm) inert gas. (Helium, Neon, Argon,...). The GM-Tube has a coaxial shape, where the inner conductor (Anode) is biased with a high voltage (~500V) relative to the outer conductor (Cathode). The Tube has a window (left side) made of mica.
This GM-Counter is build on 2 PCB's. One is a standard high Voltage generating circuit, whilst the second is a Counter based on an ATMega16™ which also handles serial Communication with a host (Environmental Control).

This website conserves all those nifty little mini-projects (gadgets) which were developed to enhance the doctoral hats of our "fresh" doctors.
Doctoral hat electronics - After seeing this section i am convinced that the next innovation will be "SmartHat". There is ample space in a cap for an Advanced Android Multimedia Gadget with a Hepta Core ARM chip and all the works. Rush to the patent office !

Amateurfunkbasteln - Amateur Radio Crafts and Electronics
But amateur radio also means tinker devices themselves, solder, apply electronics and learn something. In this sense, it can be a preparation for a technical career or even an engineering degree.
Use Google Translate, the pages are in German.
A Data Logger that records Slowly varying parameters, such as the temperature or decreasing the voltage of a battery. This copy records up to four measurements on parallel and saves it on a EEPROM.
Four Channel Data Logger
It measures self-sufficient - without a PC - analog voltages (0-5V), it digitizes and stores the numerical value obtained in a separate memory. Later, after the measuring and recording phase, passes the data logger its information to the PC.

Electro Tech has been around for nearly a decade; has a membership of practical and seasoned enthusiasts, engineers and students. Here you may find many interesting ideas for projects and repair/fixing tips.
Repairing Electronics – If you’re trying to fix an electronics device like a TV, Stereo, etc you can discuss it here.
Robotics & Mechatronics – Specific to discussions about robots and the making of bots

Professor Mark Csele - Projects and Hobbies
Nixie Thermostat - A heating and cooling thermostat employing technologies spanning fourty years from the unique Nixie tube display, circa 1960's, to a PIC 18F microcontroller, circa 2006.
A High-Powered Power Backup Inverter - The working prototype of the 2 KVA inverter is complete. Fed from an array of lead-acid cells totalling 600 Ah (at 12 Volts), it easily drives real-world loads such as single-phase motors. The inverter has been tested and found to operate at an efficiency of between 71% and 82% driving a variety of both inductive and resistive loads

"Many physical processes evolve on timescales shorter than the human eye can resolve. Effectively, this means the details of how the process changes with time are lost in a blur. High speed photography, or HSP, is simply photography with extremely short exposure times,...."

Electronic Projects of Ronald
I Colored The Sketch at Ronald's site and mailed it to him. Ronald used it in his website!!
NIXIE II A Talking NIXIE Alarm Clock! This Nixie Alarm clock will wake you up with a personal wake-up message or sound. A "wav" file stored in EPROM is played using only a few counters and a DA converter.
The µSCOPE - A poormans OscilloScope
"These days this obviously can be done much simpler. The present generation of micro controllers is so powerful that such a videoscope concept can be realized almost completely in software. Recently I obtained a sample of the 12f675. On examination of the datasheet of this small 8 pins micro controller from Microchip, it appeared that the small package contained all the components of a miniature videoscope. In short the µSCOPE project was born, with as main objective the challenge of implementing such a relatively complex task in this small micro controller. The result summarized on this web page is a fully functional (memory)scope that samples the analogue input signal and subsequently displays it on a normal TV"

I've constructed many projects over the years, from kits, built from published circuits, or designed and built from scratch. Projects from MartyBugs. digital speedo, keyboard status LEDs, temperature sensors.
