Printable Self Assembling Lamp

 Printable Self Assembling Lamp

 

 This Printable Self Assembling Lamp is an interesting concept. It starts out as a flat sheet and folds up into a box with an overhead light. The light turns on using a touch sensitive area. This is what Ikea needs to implement. :)

“The thing that comes out of the printer (it’s a rather special sort of printer) is a flat multi-layer sandwich of shape-memory polymers (they take care of the actual folding, triggered by heat), thin layers of copper, layers of paper and foam for structure, and double-sided tape to keep it all stuck together.”

Submersible Thruster

Submersible Thruster

 

If you are looking to design some underwater propulsion Dane from Transistor Man has completed a well documented Submersible Thruster build to get some pointers from.

The goal here is to design a submersible motor assembly that is able to accomplish the following:

  • Able to operate, submersed, up to 1 meter underwater while not transfering more than 10ml of coolant into the surrounding water per hour (not leaky)
  • Capable of delivering >5kw of motive thrust, when driven at 40v from a sensorless 3 phase motor drive.
  • Utilize a clear housing assembly to allow for easy-to-observe internal failures or leaks
  • Actively aid in cooling the motor assembly, using condutive heat transfer
  • Maintain a rotating shaft seal while operating up to 2k RPM. 
  • Design using easy to assemble, easy to reproduce components (ex: off the shelf bearing & shaft seal assemblies, waterjet aluminum)
  • Utilize a propeller designed to operate at 2k RPM without significant cavitation effects at speed*

Bruce in a Box Augmented Reality Project - Cornell University ECE 5760

 

Julie Wang developed the Bruce in a Box Augmented Reality Project for her ECE 5760 final project. This looks like a fun project, to see where the name comes from watch the video at 3:00.

“My system makes use of a variety of digital signal processing and computer vision techniques, resulting in a robust and reliable system. The hardware I utilized was the DE2-115 board by Altera, a Video Camera, and a VGA monitor. All of the functionality of my project is achieved through custom hardware written in Verilog. There are an extensive number of modules, and each one is designed to be as modular and parameterizable as possible.”

Wall Mounted Computer Chess Board Project

 

 

If you like playing chess this Wall Mounted Computer Chess Board Project might be something that would be a good project to add to the list. It has a vintage chess game hacked into this hand made wall hung chess board.

Thanks to Artless Dodger for sending this in.

“Parts Needed

Working Fidelity Chess challenger 8 or 9
Power adapter 8v
Coin cell battry 3v
MDF 6mm board 410 by 710
Brown or black leather half square meter
White or cream leather half square meter
Cable straps (Thin)
Acrylic glass 10 * 400L *30mm Deep * 6MM thick (2 spare)
Leds , 3Vm blue and red,
30 cms fibre optic wire ,(you only need about 10 inches.) side glow or end glow is fine.
Kynar single core 30awg transfer wire,or equivalent 30awg stranded wire. various colours
Momentary push buttons (8mm pole)
Function Buttons (built in 3v Led blue)
KIT circuit
All purpose adhesive
Sheet plastic , thinner than credit card, thicker than paper, (think phone screen protector)
Wooden frame with interior opening 400 *700 and with a 5mm underlap. If you can only get 8mm underlap you’ll need to adjust size of the board”

eBay Photoswitch Teardown

Photoswitch_Teardown_7809

 

I spotted this photoswitch on eBay and had to take a look at the guts (search photoswitch if the link doesn’t work since eBay links go stale after a short time). I now see that the same unit is sold in multiple variations which are 24V and 220V. Not sure I would feel safe with 220 on this thing though. I am curious if the 10 ohm resistor is the only difference between the versions. If someone has one of the other versions leave a comment to let us know what the difference is. These are selling for $3.39 which included free shipping from China to Canada! Hard to believe how tilted the scales are here, I wouldn’t be able to ship this within my city for $3.39. The unit is powered from 12 volts AC or DC, it also switches the same power to the third output wire when activated. The circuit is using a 555 for operation. When the photocell goes from light to complete darkness the relay activates in 3 or 4 seconds. You can view full resolution images here.

DIY Boombox

at 11:39 pm. Filed under DIY Hacks, Electronic Hacks

 

David Watts has made a DIY Boombox which is made with mostly off the shelf pieces that have been hacked together. Some of the features the boombox has is line in, bluetooth input, radio, spectrum analizer and a partially working pong game. An Arduino is built into the box to do some of the control. The box is powered from a 6 AA cell battery pack, a step down converter is used to create a nice 5 volt output.

License Plate Electric Guitar

at 6:09 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks

 

Mike Senese from Make shows us how to make a License Plate Electric Guitar. Some basic tools are used to create a totally custom electric guitar, the video shows you how to wind the pickup coil using some screws, plywood and magnet wire. When this project is done you will have a guitar to jam on. In the example video a pre built guitar neck was used but depending on how elaborate you want this could also be hand made.
