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.

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.”

DIY LED Display using WS2811 LED Strips

at 2:07 am. Filed under DIY Hacks

 

If you are looking to build a large low resolution screen stringing a bunch of WS2811 LED Strips together might be just the thing. ejunky66 shows us how you can make a cool flexible DIY LED Display using WS2811 LED Strips. The strips are stuck onto a plastic sheet, they are linked together in small grids that are then connected to the computer controlled interface. This panel won’t be cheap but can scale up much larger than your big screen TV and looks impressive from a distance. Nice thing is it can be rolled up or curved around surfaces.

3D Scanning Using an xBox Kinect

at 6:06 pm. Filed under DIY Hacks

 

Hoffman Engineering shows us how to do some DIY 3D Scanning Using an xBox Kinect. The output of the process can then be used to print on a 3D printer. He is using the first generation xBox Kinect which can be found quite cheap used since the new version is now out. He is using the free version of Skanect to get the data in. The software uses all of the Kinect sensors to grab all of the data to render the full image by just moving the device around the object.

PCB Case

PCB Case_3

 

When you design a PCB you have lots of ability to route the edges and internal shapes the way you want. Why not use the same material that is used for the circuit board for the actual case? FR4 PCBs are thin, strong, silk screened, have smooth edges, can have very precise holes drilled anywhere you like. These are all good qualities to have for case design. This is the reason ElectroDacus decided to make his Solar BMS (Solar Battery Management System) like this. If you are interested in the product there is a Kickstarter for it with lots of time left and good traction.
