Insane Fast Food

These videos are cool, too bad is isn’t real food being made. Reminds me of how the Chrome browser really works. I would like to see the setup of the equipment before the take.

Robot Cake Decorating

at 7:49 pm. Filed under Cool Gadgets


Next time you see a nice cake at the bakery that looks to be custom made you might be fooled. Many of the new Cake Decorating Robots perform such a good job you would never know they were mass produced. The interface is nice since they user can simply free hand draw the design to be replicated, the robots then go to town and start pushing them off the end of the conveyor belt.

Homemade Electronic Drum Kit

Homemade Electronic Drum Kit


If you are musically inclined a cool project would be to build some of your instruments. This Homemade Electronic Drum Kit by  is a great example of what can be developed with a bit of work. It looks great and is functional. 

“This first iteration is roughly modeled after the Roland V-drum. The main features I extracted were:

1. Piezoelectric pressure sensors for velocity-sensitive note triggering.

2. Mesh drum heads for quiet, responsive hits.

3. Dual-zone pads in which two sensors are connected to each jack. This allows for triggering two separate notes over a single cable. Usually the hits are divided as snare & rim, or cymbal & bells. This kit also features double kick pedals that transmit over a single TRS cable.

4. A drum brain that converts analog signals from the piezos into MIDI messages that a computer can recognize. Software then interprets the messages to generate musical output. In this case, I am using an Alesis Trigger I/O, which feeds into my laptop via USB.

5. Typical drum kit form-factor. Based on the number of inputs on the Trigger I/O, my kit features three dual-zone cymbals, two kick pedals, one hi-hat pedal & five dual-zone drum pads. A total of nineteen independent notes.”

PCB Bad Solder Joint

Product testing is very important, you can run a battery of electrical testing on your PCB but a visual inspection is also very important to spot failures that are waiting to happen in the future. Our friend Bob Davis has been busy repairing all sorts of random electronic items. The Bad solder joints seen above are from a Crown XTi 1000 power amplifier which is an amp that retails at over $1,000. You would think there would have been enough profit in there to allow for a quick visual inspection.

Whiteboard Erasing Robot


When you have a whiteboard all is good until you need to erase it.  This Whiteboard Erasing Robot will make quick work of it.

“The goal of this project was to create a robot which could erase written text on a whiteboard completely autonomously, i.e. no human interface. The processes involved in this project included devising a method for the robot to search a whiteboard for text, designing a way to physically move a robot to the text, and enabling a robot to erase the text.”

Sega Cartridges Resurrected using some old Computer Chips

Sega Cartridges Resurrected using some old Computer Chips


Dragao has a Sonic Cartridge that had some invalid instructions that would cause the game to crash at a certain point. The solution wasn’t to find a replacement game at the local flea market, he Resurrected the Sega Cartridges using some old Computer Chips. The game was originally loaded on 16 bit memory chips, not having any of these handy from the donor computer motherboards he piggy backed 2  8 bit memory chips to make it work. An Arduino was then used to blast the code onto the new chips.
