When you are making some prototype PCBs it is quite simple until you go double sided, now you need to potentially solder through hole components on both sides, stick small wires in each via and solder both sides or insert small rivets in the holes. DIYyouwhere is playing around with a method where they attach a brush to the drill so that they can electrically detect when the metal

If you are running out of room in your house most people would build an addition, build a room in the basement, re-purpose the garage or move. Colin Furze is not following the normal thinking here. He dug up the backyard of the house tossed in a ton of concrete and steel to make an underground bunker which is hidden from view from pesky neighbors. Watch the video above

I really like the hidden USB storage drive which is mounted with a secret keyboard sequence. If the keyboard was just regular looking that would be very secure since who would think there was some secrets lurking
You can see the case above that Tony Flynn built the Internet Radio project around. The outside may look old but the internals are sporting a powerful Raspberry Pi. It uses your local wifi to tune in internet tunes. “The radio is configurable by anyone and no programming skills are required. Â All the stations and settings are stored in a text based configuration file which is stored on
This is an inexpensive component tester called the FISH 8840 which you can find from many online eBay retailers for around $30. The interface is very simple, attach a device to be tested and press the test button. It turns off after about 20 seconds, pressing the off button puts it into sleep mode immediately. There is a ZIF socket that allows you to insert leaded devices and pads
Peter Oakes goes over a Arduino based Industrial PLC system called Industrial Shields. If you are an Arduino programmer and are looking to incorporate your design into something that is a bit more robust this might be for you. I was thinking the system would just use some of the standard Atmel chips that are common in Arduino systems and just use the IDE for programming but it actually incorporates the real
