Tweet direct to a Thermal Printer

at 8:03 pm. Filed under Complex Hacks, DIY Hacks, Electronic Hacks


If you like Twitter you need to have a look at this permanent Twitter Feed machine which allows your Tweet to go direct to a Thermal Printer.

“Thermal Tweeter is hacked together from a SparkFun thermal printer and the web platform internet development board. No computers are used to query twitter or run the printer, this is a 100% stand-alone Twitter appliance.”

Android controlled Labyrinth

at 10:56 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks, Game Hacks, Insane Equipment, Toy Hacks

We have featured Labyrinth game hacks in the past but this Android Labyrinth Game is the biggest one I have ever seen. The game is controlled by a person tilting an Android tablet which directly controls the movement of the huge game board. The ball appears to be a bowling ball and by the looks of it the game is actually quite hard to master. I wonder where this game will live after the event, it isn’t like one of the developers could put it to use in their basement. Instructables user pcdevltd was at the Google event where this game was unveiled and was inspired to make his own. The scale isn’t the same but the concept is identical. You can see a video of his DIY Android Ball Maze below, if you are interested in building one he has done a great job of documenting all of the steps.

PIC 16F1937 Capacitance Touch Switch Keypad Example

at 10:43 pm. Filed under DIY Hacks, Electronic Hacks


Many PIC microcontrollers have built in touch pad capability. The PIC 16F1937 for example has 16 inputs for the capacitance module. These allow for a simple and inexpensive way to add buttons to your project without adding physical switches. Nice thing about these switches is that they will not fail after a certain number of uses like a physical switch will. Our friend Giorgos Lazaridis from PCB Heaven has designed a circuit which uses the PIC 16F1937 Capacitance inputs to make a keypad which outputs BCD.

“The fundamental rule when designing a touch-pad is this: Keep the wires as close as possible. When i designed my keycode doorlock project, i had only one PIC to handle everything including the touchpad. But the PIC was hidden inside the door, so i had long wires (about 10-15cm) to connect the pads with the PIC. That was a bad idea. So, i came to the conclusion that the touchpad must have a dedicated PIC on-board to minimize the wire length.”

DIY Vehicle Mounted Remote Control Camera System

at 8:31 pm. Filed under Electronic Hacks

Ben Heck has a pretty cool job hacking things together on his Ben Heck Show which is sponsored by Element 14. I just heard is that a full second year of episodes has been green lighted so stay tuned for a bunch of new episodes! I hope that Ben is enjoying the builds as much as it looks, I hope that time line pressure doesn’t burn him out… In this episode Ben hacks some gear for Phil Golden’s “Expedition Awareness” Jeep with custom-mounted remote cameras and an internal LCD monitoring system to get it ready for a 5,000+ mile cross-country journey dedicated to raising awareness for ALD.

“From writing the code for the stepper drivers to programming the micro controllers for the virtual tripod pan control to routing and finalizing the components for the video display system –  four, four-inch LED backlit LCD screens – the project was a modding labor of love for Heck. Phil and his team will use the cameras to capture each phase of the expedition, beginning with the Continental Divide spanning New Mexico to Canada to a second leg of the journey looking at America’s heartland from the East Coast to West Coast, and culminating in an urban area and off-road exploration of Canada. Designed to instill hope to those touched by ALD, the documentary aims to entertain and educate by combining adventure with information and real-life stories.”

Hand Soldering an LGA Surface Mount Chip

at 8:56 pm. Filed under DIY Hacks, Electronic Hacks

With electronic parts getting less and less hobby friendly there will come a time when you can’t get a part in a through hole DIP format. Our friend Dave from the EEVBlog has a new 3 axis accelerometer that he is playing with. The issue is that it is a LGA surface mount chip these chips only have pads on the underside which makes it a pain to work with unless you are using solder paste and reflowing. Dave demonstrates how the part can be stuck upside down onto a project board using some super glue and then using some wire wrap wire the part is able to have its pads soldered to the project board. The soldering looks simple when it is magnified this much but after soldering these wires onto a thumb drive for the VHS Tape Storage Drive Project I know first hand how hard it is.
