This 4 page worklog goes through the process of building a DIY soldering station. Complete with variable temperature and LCD output of current temperature. A cheap soldering iron is used which made me queasy, but it seems to have worked out just fine.

Every once in a while someone with wayyy too much spare time does something cool with lego’s mindstorms. Bringing you back to all those stuffed animals you won but didn’t need, this is the lego crane. The building instructions are even available for this, but most important is the must see video of the crane in action.

Using off the shelf parts and a standard PIC microcontroller here’s a weather station that you can access remotely. The PIC takes care of all the data acquisition and serial transmission. Hardware schematics & software are included in the project write-up. Take a look!

Here’s another great analog project: A DIY Geiger Counter. The parts are all, for the most part, off the shelf and easily assembled together. The project write-up is extremely detailed with everything you’d need.

For people who are ‘musically’ inclined here’s a great project. The Laser Harp is exactly what you think, no strings, just lasers! The project write-up includes a lot of info on how to make it and an awesome video of the Laser Harp 2010 in action.

Since we’ve become to accustom to using PWM to make LEDs fade in and out, we forget about our roots in the analog world. This project & write-up gives a straight forward circuit and a good explanation of it’s operation to those of us whose analog skills are a little rusty. Fading LEDs…they are just somehow simply amazing.

Found Electronics’ Project 3 pieces is probably one of the more artistically inclined projects that I’ve seen. They combine the art of electronics, music and plants all into one piece. There’s a lot of pictures and a good write-up that illustrate the purpose and goal of their project.

This is a cool little project that uses a PIC microcontroller to build a voltage output display for a variable power supply. The circuit schematic and software for the pic are included in the project write-up. The pure simplicity of this project is very refreshing, take a look!

It’s not even close to an analog computer, yet it reminds me so much of them. This computer is built purely from TTL counters. The instructions are stored in two EEPROMs and the old school style is definitely worth a look. The write-up gives you a great idea of why we love microcontrollers so much.

Anyone who has been around circuits long enough has at one time or another stumbled upon the simple 2 transistor FM transmitter. For nostalgic purposes I’ve put it up today. The quick post explains how to build it and also goes over some of the less obvious factors about FM.
