POV Globe

at 10:50 am. Filed under Cool Gadgets, DIY Hacks

 POV Globe

 

Antonin Martin-Schouler had created a nice POV Globe. IR is used for position detection, a slip ring gets power over to the globe, it is packing some serious processing power with the ARM processor running the show.

“For building the device using this tutorial, you’ll need the following material:

  • The Zybo board from Digilent
  • The Neopixel LED strip from Adafruit
  • A 12 wires slip ring like this one from Adafruit
  • The GP1A57HRJ00F Sparkfun photo interrupter breakout board and the GP1A57HR photo interrupter that you can find here and here
  • A 12V DC motor
  • A micro SD card
  • A cross-compiler for ARM processors”

RC Car GPS Follower

at 8:55 pm. Filed under DIY Hacks, Electronic Hacks

 

If you have some RC gear and a few bits of GPS electronics this project that iforce2d built might be worth a look.  Have a look at it in action at 2:40.  The user has a GPS module and the car has a GPS module, the module with the person sends its position to the car and the car goes to that location, issue with GPS is that it isn’t very precise so following tight corners is quite challenging. This would perform great in a field though, I would like to see this connected to some farm equipment in the field. There is some code here that will help you build your own.

GPS Guided RC Boat

 GPS guided boat

 

This GPS Guided RC Boat project is a great way to capture some interesting pre-determined navigation scenes. The boat does a great job of navigating until it hits something or gets swamped. Joseph Fortune has a page that provides build details and code so you can make your own.

 “Here is a rough layout of the parts. The 9V battery hooked to the engine was actually one of those 7V rechargeable RC battery packs. The other 9V battery was to give the Arduino its own noise-free power source (Noise from the engines kept resetting the Arduino). Here I used the Adafruit GPS breakout board, when the project actually used the GPS shield, but they didn’t have the graphic. Other than that, this should be pretty faithful to the actual design.”

Box that can be Unlocked with a Flame

at 3:24 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

Alex Glover created a locked box project, some project boxes need a secret knock code to unlock, GPS positions to unlock and dice roll combinations to unlock. I think this is the first time I have seen a box that is unlocked by a flame. Nice thing is that it is not obvious that the box is opened in this way. I think it would be nice to have a certain flash pattern needed to make it hard for observers to see how to unlock it.

GSM Power Monitor and Control

GSM Power Monitor and Control

 

If you would like to keep better track of your energy usage this GSM Power Monitor and Control by Idris Zainal Abidin might be just what you need. There isn’t much details so you would not be able to build it from the article but it should be enough for some inspiration to build your own creation.  The modular build looks great even though it would not be best suited for a compact instillation.

Cliff Test – Constant Current Variable Load

at 10:18 pm. Filed under DIY Hacks, Electronic Hacks

Cliff Test - Constant Current Variable Load 

 

Check out the Cliff Test, it is a Constant Current Variable Load by TimNJ. It is based on the popular inexpensive load tester circuit that Dave Jones built a while ago. 

“Here’s some information about it:

-External AC/DC power suppply
-Fan cooled (no temperature control at the moment)
-Load switch (with LED indicator)
-10-turn pot
-Internal trimmer to set max current (currently set at 1A, but can most likely do 2-3A)
-Yellow and black banana jacks for current measurement (1A/1V)
-10x 10ohm Vishay CPF3 (3W) resistors”

Raspberry Pi Minecraft Blocks with NFC

at 4:47 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Game Hacks

 

If you are into minecraft you will soon be able to use some technology to interact with the game using physical objects. Adafruit is making this possible with an NFC reader that they will be releasing soon.

 

“Coming soon to the Adafruit Learning System, a project to make paper Minecraft blocks that interact with the game on a Raspberry Pi using NFC (near field communication)! Swiping a block on the Adafruit PN532 NFC reader causes it to be created in a Minecraft world running on a Raspberry Pi.”
