Arbra Dynamite Exploder taken apart

at 8:54 pm. Filed under Insane Equipment

 

 

Bigclive shows us what is inside a Arbra Dynamite Exploder.  The unit is completely powered by the turn handle. It is actually quite nice since it will indicate that the circuit resistance is when the handle is spun. The max firing voltage is around 1000 volts. To fire you simply press the fire button as turning the handle while pressing the fire button. When the fire voltage is reached the unit dumps the built voltage onto the output to allow any pyro devises to be fired.

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.

Tiny Circuits have made a playable Tiny Arcade Cabinet kit. The environment is a tiny custom Arduino system. It is stackable and of course very small.

The Tiny Arcade lets you relive the golden age of video games with an arcade cabinet that fits in the palm of your hand.  Originally launched on Kickstarter!

  • Beautiful, vibrant full color OLED screen  
  • Games are free and open source – play community made games or write your own
  • SD card expansion slot – download new games and insert card (or get a preloaded microSD card here)
  • High quality joystick and two push buttons
  • Built-in speaker with volume control knob and rechargeable lithium battery
  • USB port for charging and game development
  • Clear and Black Acrylic
  • Arcade stickers to decorate your cabinet
  • Electronics based around the same 32-bit ARM processor as the Arduino Zero “

Cost to Manufacturing Your Hardware Product

at 7:45 pm. Filed under Educational

 

 

Make has a great article that goes over what things to consider when wanting to manufacturer your hardware product. They bring up that the case often one of the largest costs of the product due to needing to make molds. There is the area between low and high volume manufacturing where using an off the shelf case would be cheapest but at some point getting a custom case manufactured for your product would make more sense.

“When bringing your product to market, scaling costs will likely be one of your biggest obstacles. Failing to plan for these costs will make it impossible for your product to succeed. For most products, the cost to transition from making a few prototypes to manufacturing thousands or millions of units is the most expensive obstacle.”

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.

Antenna filled with Acorns

at 9:08 pm. Filed under Funny Hacks

 

 

This Antenna filled with Acorns certainly would not be operating properly. Looks like a squirrel had found the best hiding spot ever. I wonder how long it took for 300 pounds of acorns to be jammed into the antenna? I bet if you had a look at the efficiency of the antenna it was taking a gradual nose dive as more and more nuts were stored inside.
