Fresh hacks every day
We get a ton of tips about weather balloon launches taking hobby electronics into space. But every once in a while one of them stands out from the rest. This project does send an electronic payload into space, but it also lets [David] fly his hardware back from near-space using an RC airplane. The return vehicle is unpowered, but that shouldn't be a problem as launching from a weather balloon … [Read more...]
We've said our piece over Makerbot and their interpretation of what Open Source means, but the fact remains if you're sourcing a 3D printer for a high school shop class or a hackerspace, you really can't do much better than a Makerbot Replicator. Apparently Makerbot is looking to expand their 3D design and fabrication portfolio; they just announced an upcoming 3D scanner at SXSW. It's called the … [Read more...]
Ah, PIC vs. AVR, the never-ending battle of electronic design supremacy. Some people swear by Atmel's AVR microcontrollers, while others are wrong. [majenko] is firmly planted in Microchip's PIC camp, so he wrote up a nice comparison of Atmel's AVR versus Microchip's PIC family of microcontrollers. The results aren't that surprising; PIC microcontrollers come out as a better product that no … [Read more...]
With daylight savings time starting up, you might not have quite as much need for lighting, but this pair of hacks should keep everything well lit whether outside or indoors. Check out the videos of both in action after the break. The first lighting solution comes to us from [Ben]'s Youtube channel. It's a simple solution, press-fitting a clamp light into a 1 inch PVC Tee to attach the light to … [Read more...]
This is [Paul Mandel's] Ground-truth velocity sensor. That's a fancy name for a device which tracks the movement of a vehicle by actually monitoring the ground its travelling over. This differs from simply measuring wheel rotation (which is how traditional odometers work) in that those systems are an indirect measurement of motion. For us the interesting part is the use of an ADNS-3080 single-chip … [Read more...]
