Microchip ENC28J60 Project

at 7:35 pm. Filed under Electronic Hacks


Kenneth Finnegan is working on a project to allow his microcontroller projects talk to the magical world of Ethernet. Without special systems like an ioBridge module a typical project would only dream of speaking to other systems unless a computer was introduced in the mix. Kenneth is using the Microchip ENC28J60 to do the heavy lifting in this case and by using a proto board from ElectroBoards the final result is quite small. We have featured this Ethernet Weather Station in the past if you need more Ethernet project ideas!

Microchip’s ENC28J60 is a 28-pin, 10BASE-T stand alone Ethernet Controller with on board MAC & PHY, 8 Kbytes of Buffer RAM and an SPI serial interface.

Geek Flip Flops

at 2:32 pm. Filed under Funny Hacks


Skechers Shape Up Shoes sent in a cool Geek Inspired Flip Flops list they made. I think the metal detector flip flops are my favorite. I am hoping that the picture below is just a prank picture! These guys have an electric grill in the middle of a small pool and there is a pairs of flip flops holding the power bar just barely out of the water. Maybe they are hoping that the GFI will save them!

“Made of chunky black plastic, these foot-bound money-makers are durable and comfortable as well as a potential ticket to a goldmine. The actual control box stays on your calf thanks to an elasticated band, and the box itself is no more obtrusive than, say, a walkie talkie (though you’d be mad to strap a walkie talkie to your leg unless you were a contortionist). Anyway, the point is that the Treasure Seekers are a great deal easier to use than the traditional metal detectors and, if you want them to be, they’ll be very discreet. Now you can combine your country walks and strolls in the surf with discovering treasure!

  • Metal-detecting sandals.
  • More user-friendly than traditional metal detectors.
  • Find buried treasure just by walking about.
  • Detector pack straps to ankle via elasticated band.
  • Pack will vibrate or beep when metal is detected underfoot.”

Lenz’s Law – Magnet falling slowly in Copper Pipe Demonstration

at 5:07 am. Filed under Complex Hacks, Educational

If I learnt about Lenz’s Law in high school I must have forgot about it. Watch the cool demonstration above where a stack of neodymium ring magnets are dropped into a copper pipe. Of course copper is a non magnetic metal so the magnets will not stick to it. You would probably guess that the magnets would simply fall at the same rate as if they were just dropped. Well if that is what you thought you would be mistaken. Due to Lenz’s Law the magnet falls very slowly through the pipe. Watch the video below for a good explanation of what is going on here.

“Lenz’s Law applies the principles of energy conservation to situations that involve forces in electromagnetism. To see an example, move a magnet towards the face of a closed loop of wire (e.g. a coil or solenoid). An electric current is induced in the wire, because the electrons within it are subjected to an increasing magnetic field as the magnet approaches. This produces an EMF (electro-motive force) that acts upon them.”

Nerf Gun Hack – Secure Area and Fire on Intruders – Part 3

at 6:00 am. Filed under DIY Hacks, Electronic Hacks, Toy Hacks


UPDATE: The project is complete have a look at everything here. Nerf Gun Hack part 1, part 2, part 3

This is the final part of the Nerf Gun Hack. Check out part 1 which goes over the how the chosen gun works and part 2 which goes over the electronics used in the project. This time a completed perfboard version of the project is built and the system is installed into the final setting. As you can see the gun is mounted into my daughters music room and the gun is hidden amongst some of her dolls. The IR Transistor and IR LED is mounted to one end of the wall unit and a table leg. The IR beam that is created is just past the entrance of the room, far in enough for the door to miss it. When you walk into the room and break the beam the gun will fire directly at you. My daughter hits the floor in the video but don’t worry, she is a good actor… These foam darts don’t hurt. πŸ™‚ There is a quick schematic in the picture gallery below, it is hand drawn so hopefully everything is legible.

If you want to make your own you can get the source code from here for free.

Perfboard Prototyping

at 4:51 am. Filed under DIY Hacks, Educational, Electronic Hacks

Collin Cunningham made a great video about the benefits of using perfboard for prototyping circuits.

Via: Adafruit

“When you think “DIY electronics,” one of the first images that likely comes to mind is of parts and wire soldered to a standard piece of perforated circuit board — and that makes sense. Perfboard is widely used because it’s so versatile. Essentially, it’s just a grid of potential solder-point connections.”

DIY Sidecar Superbike

at 4:26 pm. Filed under Complex Hacks, What Were They Thinking


FranΓ§ois Knorreck works as a technician in a hospital in France, but when he isn’t working he tinkers with motorcycles. He spent 10,000 hours over 10 years and spent 15000 Euros on this DIY Sidecar Superbike. After all is said and done the bike looks a bit different than it did when the build began! FranΓ§ois has documented some of the build details here.

“While this is a very special vehicle, the Laverda touch is obvious. This is not only the triple engine which does that but probably a smart and hard work on the global design. The rear part recalls the RGS side panels. The glorious triple 1000cc seems magnified in this red dress.”
