Fresh hacks every day
This OWI robot arm has been hacked to add position sensors and Arduino control. [Chris Anderson] took one look at the Launchpad controlled OWI from earlier today and said “wait a minute, I’ve already posted my own version of that project”. Well, that will teach him not to tip us off about his hacks!
The position control is a … Read the rest
Check out this setup that [Ruenahcmohr] is using in his air muscle experiments. The orange mesh contains an air bladder that is connected to a hose on the right side. The bladder can be filled, or emptied with two solenoid valves not seen here (but you can get a good look in the video after the break). The muscle attached … Read the rest
Needing to test the display interface for a multitude of different sensors [Fileark] built himself this analog and digital input/output simulator. Along the bottom is a double row of trimpots that adjust analog voltages. Each voltage is measured by the Arduino inside and its value is displayed on the graphic LCD screen to confirm that the hardware you’re testing … Read the rest
This analog computer can multiply, divide, square numbers, and find square roots. It has a maximum result of ten billion with an average precision of 2-3%. [Miroslav's] build recreates something he saw in a Popular Electronics magazine. It uses a resistor network made up of three potentiometers with a digital multimeter is an integral part of the machine. To multiply … Read the rest
Here’s a watering can and water vortex that are controlled with a webkit browser interface. The interface displays a drawing of the watering can on your browser. If you grab one of the handles on the circle around the image and move it, the can will rotate as well.
Okay, so this isn’t going to change the world and … Read the rest
Props go to [Michael Nash] for establishing an interface between National Instrument’s labVIEW and an Arduino (an example video using a potentiometer is above). Personally, from the one time we were forced to use labVIEW, we hated every second of it.
One reason it’s so terrible, is the Data Acquisition Modules cost well into the hundreds of dollars, yet the … Read the rest
[Gijs] cracked open his Game Boy and added some parts to give him more sound synthesis control. He uses Little Sound Dj (LSDj), a popular Game Boy program used to pump out those classic 8-bit sounds. The unit seen above and heard in the clip after the break has an added potentiometer and circuit board. He’s got a few … Read the rest
