This project shows you how to build a continuity tester using less than 20 parts. The schematic and build is very straight forward and the result is a test tool that goes ‘beeeep’ when two test points are connected with a wire.

Taking another quick break from projects, here’s an awesome guide I found for soldering. It lists out the best way to solder each different type of component in existence. This is very valuable info for people just beginning to solder. Burning out parts after soldering them into place is never fun! Learn to solder correctly.

Using a small FPGA board you can build a decent quality oscilloscope! The hardware schematic and software is already there for you to download and most of the parts are pulled straight off the shelf. Don’t miss this DIY pocket oscilloscope, it’s cheap and very mobile.

Sure you can buy one of those battery-free flashlights in the store, but why bother when you can easily make your own! This project goes through how commercial manufacturers build their flashlights and how you can make your own, but with better quality.

No that isn’t the hand of god inside of your oscilloscope. It’s actual video. I’m not exactly sure why you would want to, but here it is, a project that shows you how to put video signals into your scope. View yourself in black and green like never before!

Taking a break from looking at projects. Here’s a quick list of must have tools and test equipment for any pyroelectro. The “helping hands” seen in the picture are a great investment, but you really need to superglue them to a heavier base. Take a look at the rest, you will definitely see something new and useful.

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.

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!

Today’s project is another method for PCB fabrication: printing directly onto the pcb. The project write-up details how he did it and gives links to how others have as well. Some pretty good quality came out of this method, so it’s likely catch your interest as it has mine.

This tutorial guides you through the toner transfer process of making a 1-layer PCB board. The board made in this example is a simple 1.2v – 2.5v – 3.3v – 5v power supply board. There are many pictures and videos to help guide you through the process.
