Inside the EDSAC Computer

  A look Inside the EDSAC Computer shows us how much we take for granted these days. Funny how when there are no concepts to work with the methods of storing and executing information you get things like mercury delay systems.

A look inside a 10GHz Microwave Link

  Mike takes apart a 10GHz Microwave Link. You can see that this is a really precision piece of equipment, the wave guide piece is very interesting. Not sure what the cost of this is but I can guarantee it would not be cheap. There is quite a lot of electronics on the transmitter which as you would expect is very nicely laid out, there is obviously a lot of things

Name the Thing Contest – 285

  The prize this week is a HMC5883L Triple Axis Compass Magnetometer Sensor so you can add some directionality to your next project. This contest will run for one week (July 18 – July 24, 2015). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please do not give the answer in the comments. Send an email to

Old Computer Hardware Instrument Ochestra

  There are lots of mechanical computer parts that you can bring to life to make some music. Computer are full of parts that can get this done. This Old Computer Hardware Instrument Ochestra shows us what is possible with some effort. “This project uses old floppy drives, hard drives, and my 3D printer and uses them to do something they were never designed to do: play in one of

Opening Garage Doors in Seconds using the De Bruijn Sequence

  Many garage door openers are not very secure but there are still thousands of codes that need to be transmitted. If these codes were being entered manually it would take a long time to go through all the possibilities but of course we could just use a small processor to run through the combinations. Samy used a kids toy that had all the required hardware to do the task,

PIC24 Dev Board Design

  Dev boards are great when trying to get a high pin count (non DIP package) microcontroller prototyped for your next project. There are some SMD breakout boards (you can see one of those in the picture connected to his dev board). But working with just a breakout board can be a bit of a pain since the connections to the board can be hard to maintain since the package

Laser Cut Tortilla Record

  Don’t play with your food. Ok, lets make an exception if you can make your food playable on a record player it is ok.  Check out this interesting Laser Cut Tortilla Record by UpgradeTech. A laser machine actually cuts playable audio tracks into this tortilla. Via: Adafruit
