Infrared Transmitter Arduino Home Automation

at 7:37 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

Upgrdman shows us how to make an Infrared Transmitter Arduino Home Automation system. This system uses a very high power wide range IR LED so that it would be great to be placed in the general area of the equipment you would like to control. If you are interested in making your own the example code is provided.

“In this video I show an easy and low-cost way to do some home automation. I setup an Arduino with an infrared receiver and transmitter, then use it to control my television and a tower fan. This setup can be used to control pretty much anything that has an infrared remote, even air conditioners.”

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.
