Fresh hacks every day
Push-wheel switches are somewhat older technology, but [John Boxall] from the Little Bird Electronics blog shows us that they are still quite useful today.
In a quick but thorough demonstration, he discusses how this input technology works, showing off both single digit and multi digit inputs. The former is pretty straightforward, with each of the counter’s outputs tied to an … Read the rest
The robot dog you see above is a mystery. [Daneil Dennet], a professor of philosophy at Tufts University found this in an antique shop in Paris. Apparently it has no identification and no one has been able to tell him anything about it. It was made in the 50s, and that seems to be all he knows. He’s offering a … Read the rest
If you have had it with persistent weeds that seem to come back no matter what you do, here is an ‘environmentally friendly’ way to kill them off permanently. By using a probe charged with 2400 Volts, [Jack] shows how you can conduct the electricity through the plant and all the way down into its roots while scorching the living … Read the rest

Short of developing telekenesis on the spot, there’s little you can do other than get up and fetch the book yourself – that is, unless you have an army of Swarmanoids to do your … Read the rest
[Shawn McCombs] is up to no good with his first Teensy project. The board you see above takes the input from a PS2 keyboard and converts it to a USB connection. Oh, and did we mention that it also keeps track of everything you type as well?
From the beginning the project was intended to be a keylogger. It’s … Read the rest
[Matt Richardson] came up with a doozy of an idea: using an Arduino to monitor the closed caption on TV and mute it when news about ridiculous celebrities is on-screen.
He’s using the video experimenter shield to monitor the captions. This shield connects via composite video, and can be used to decode the binary code that carries the captions in … Read the rest
[Alexis] sent in a single board computer he’s been working on. The project goal of his build was making it easily reproducible. From looking at the schematics, it’s one of the simplest fully-functional computers we’ve seen. The build runs CP/M 2.2 off of two 3.5 inch floppies. This opens up a lot of options as to what software is already … Read the rest
