Fresh hacks every day
This hexapod was made almost entirely via 3d printing (translated). The parts that you need to supply include a few fasteners to make connections, twelve servo motors, and a method of driving them. As you can see in the video after the break, all those parts come together into a little robot that functions quite well. The only thing that we think is missing are some grippy feet to help prevent … [Read more...]
Learning about how infrared remote controls work is a great way to expand your electronics knowledge. That's because this technology is invisible to our eye, and happening faster than we can comprehend without help from test equipment. This tutorial over at Pyroelectro talks about the theory behind how the data is transferred and shows you how to build a couple of circuits to experiment with and … [Read more...]
Ever wonder how to calculate revolutions per minute using a microcontroller? This project shows you how by purposing an IR emitter and detector and a computer fan. As the fan blades spin they disrupt the beam of infrared light between the emitter and the receiver. This results in a waveform on the receiver's circuit which can be easily used to trigger interrupts in any microcontroller. In this … [Read more...]
This hack lets you use a TV in place of a graphic LCD screen. But we like to think of this less as a replacement for a GLCD and more of a simple way to get your information onto a television. A PIC 18F452 acts as a translator between the GLCD parallel inputs and a composite video output. There are some malformed image links on the page which we've fixed and linked to after to the break so that you … [Read more...]
