Automatic Pet Water Bowl Project

at 9:41 am. Filed under Cool Gadgets

Automatic Pet Water Bowl Project


Using a Raspberry Pi Acmecorporation made this Automatic Pet Water Bowl Project. This project is designed to keep your pet bowl filled with fresh water and also gives you the ability to keep an eye on your furry friend. The designer is a native french speaker so there are a few spelling mistakes but his English is much better than my French. :)

“During the summer, when i leave at home my dog for several hours, i have the problem that water inside its bowl become warm in few time. Then i’ve create this system that can empty and re-fill the bowl with fresh water each preselected time, maintain constant water level and finally spies my pet.”

Flamethrower Ukulele

Flamethrower Ukulele


Have a look at the Flamethrower Ukulele that  from Make built. Might not be the project that you want to use indoors or around anything flammable that you care about. But if you have a fire extinguisher by your side this sure would be fun to build, if you are an outdoor performer this would double as good crowd control. The system uses a modified calking gun to squeeze a small butane cylinder allowing the gas to flow down a hose to the end of the ukulele neck. A spark ignites the gas and starts the flaming fun.

Pixel Pacman

Pixel Pacman


Mike Szczys from Hack a Day built this great low res 1 Pixel Pacman game. If you had fun playing video games from the 90s you would love this. It is a classic game of pac man built around a 32X32 RGB Pixel display and is powered by a Teensy 3.1.

 “The hardware and software running the Smartmatrix made the display portions of the project really simple. First off, the Teensy 3.1 is fast, running at 96MHz in this case. Second, it has Direct Memory Access (DMA) which [Louis] used in the Smartmatrix library. This means that driving the display takes almost no CPU time at all, leaving the rest for your own use. This example of a game is under-utilizing this power… it’s totally capable of full-motion video and calculating amazing visualizations on the fly.”

Origami Robot unfolds with Heat and gets to Work

at 9:41 am. Filed under Cool Gadgets, What Were They Thinking

Origami Robot unfolds with Heat and gets to Work


This origami robot starts as a flat sheet, once heated the origami magic starts. Within a minute the robot folds itself to life. Once the structure is done it is ready to get to work. Thanks to a small built in magnet some external electrical fields allow the robot to vibrate around and get to work. It is very insect like in its movements and can actually get some productive work accomplished.

“The unfolded robot, which is made of a magnet and PVC sandwiched between laser-cut structural layers (polystyrene or paper), weighs just 0.31 g and measures 1.7 cm on a side. Once placed on a heating element, the PVC contracts, and where the structural layers have been cut, it creates folds. In under a minute, the robot is finished, and is ready to go, zipping around at speeds of between 3 and 4 cm/s.”

Sensorian – Sensor Shield for the Raspberry Pi

at 9:09 pm. Filed under Cool Gadgets

Sensorian - Sensor Shield for the Raspberry Pi


The Sensorian is a  Sensor Shield for the Raspberry Pi. There is a Kickstarter that still has 24 days to go and is less then 2K from tipping. So if you like developing with the Raspberry Pi and need something to monitor possible input I can think of this might be the shield for you. The device can detect ambient light, temperature, pressure, altitude, motion, magnetic fields, capacitive touch, and time with a real time clock

Google’s Project Wing Delivery Drone Prototype

at 11:29 am. Filed under Complex Hacks, Cool Gadgets, Insane Equipment


Can’t wait till this style of delivery method is available. Tested had a first hand look at the Google Project Wing Delivery Drone Prototype. Not that it will have a direct replacement for things such as pizza delivery since the payload needs to currently be quite small but the flight and delivery method is great. Scaling these up to handle larger packages would make it great for package delivery directly into your secure back yard in minutes. I guess the only concern people will have is what happens when something goes wrong and it falls from the sky and knocks someone in the head.

Nokia Phone Arduino Shield

Nokia Phone Arduino Shield


If you have one of these classic Nokia phones in your desk you might want to put it to use.

Via: EEVBlog Forum

“I am making an Arduino shield to interface with old Nokia phones. I’d like to keep the price around $20 for the shield, cables, and phone. If I can get some software help from the community, this will be great for interfacing projects with the internet.

For photos, code, and a detailed writeup please check out my post at http://paxinstruments.com/nokia-phone-arduino-shield/

  • Should the shield be for a specific Arduino board or be configurable? The AltSoftwareSerial library uses specific pins for different Arduino boards.
  • Is it fine to have the phone and serial-to-USB chip both connected to the Arduino RX/TX lines?
  • Do we need the level shifters?
  • Is there a better Nokia cable that also provides power?
  • The Nokia 3100 needs a battery to run even with the power cable inserted. Is there a way around this?
  • Is there a better target phone?
