ClearWalker – Polycarbonate Walking Robot

at 9:52 am. Filed under DIY Hacks, Electronic Hacks

 

Jeremy Cook built this walking robot  using a bunch of custom cut Polycarbonate for legs and gears. The brain is Arduino based and GoPro camera in the head. The motors are controlled via a few off the shelf H-Bridge modules. Controlling the robot is done via bluetooth.  Lots of time and thought went into this robot creation and it shows. It looks great walking around the beach .

Talking Multimeter Project

at 8:53 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks

 

 

Rachel Dipirro and Jonathan Lo made an interesting Talking Multimeter Project for their Cornell University ECE 4760 Final Project. The multimeter is built around a PIC32MX250F128B. This is not a robust product that will be replacing your desktop multimeter since the range is not that great. For example it can just read resistance between 0 and 50K and voltage up to 10 volts. This range is fine for lots of work and the measurement front end could easily be swapped out with a high resolution ADC to greatly enhance this.

The multicolor LCD display is a great way to display the output and the number pad is perfect to control the system but of course the heart of this project is the voice output. The speech synthesis is performed by transmitting data to an external Microchip MCP4822 SPI DAC, the samples that are played are 16kHz samples that were compressed and stored onto system flash.

3D POV Display

at 10:45 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks

 

 

There are lots of POV displays out there, lots have multi color LEDs that can display some impressive images. has built this  3D POV Display that has lots of tech going on. The addressable LEDs are setup in strips of varying heights. When spun this allows the display to create 3D images in color. A Parallax Propeller microcontroller powers the main display while an Arduino Pro Mini works with the ESC to keep things turning properly. To get power to the spinning portion of the board a wireless power module is used, this module can get about 10 watts of power through the air gap which is plenty for the LEDs.

Automated Outdoor Lighting

at 10:49 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

 

Steve Marriott wanted to have some automated outdoor lights. They will be controlled by an Arduino that will monitor some PIR sensors to see what is going on and turn lights on based on activity. A few tictac boxes were used to mount the outdoor electronics in. The project changed over time based on community help. The end result is a a completely automated lighting system that looks great and provides a ton of light.

Macbook Backlight Repair

Louis Rossmann shows how he walks through a Macbook Backlight Repair. As usual the scale of the repair is tiny and work under the microscope is needed. Some tiny jumpers and a steady soldering hand come to the rescue.

Pizza Box Robot That Shines a Laser in Your Eye

at 10:48 pm. Filed under Computer Hacks, DIY Hacks, Electronic Hacks

 
 

Michael Reeves is a software developer at Infibit that has made a face tracking robot that is housed in a pizza box, it tries its best to find your eyes and shine a laser in them. The software that runs on a PC was written in C# and uses Emgu CV which is the .NET version of Open CV for the facial recognition portion. A web cam is connected to the computer scans for a face to attack, when detected the coordinates are sent over a serial cable to a microcontroller.  The ATmega 328 microcontroller has a few servo motors connected to laser pointer. Since the servo motors can move the laser pointer in XY positions the coordinates are used to point where it needs to. The result will annoy you and your guests. I think this would be useful at popular store displays when you need people to move along after having a quick glance. If you are looking to build your own version you can find the code here.

DIY SOLAR TESLA POWERWALL

at 11:40 pm. Filed under Cool Gadgets, DIY Hacks

 

Instead of purchasing a Tesla Power Wall jehugarcia shows us how a DIY version can be put together. The EV West facility has a large flat roof which makes laying the panels nice and easy. The roof is crazy high so getting them up on the roof looks like it was not that simple. The video at the top shows a bit of the solar panel installation and the lower video is an update on the system showing how the system is wired. This system is basically used to charge EV vehicles but there are some regular outlets that can be used for regular plug in equipment if there is a power failure. The Tesla car batteries are mounted in a standard electrical off the shelf enclosure. There is no continuous battery monitoring on the battery packs but rather a header that a battery balance monitoring system can be plugged into whenever they would like to check the levels.
