Fresh hacks every day
We're a long way from the Aquanet-powered plastic pipe spud guns of our youth. [smirpab] over on the SpudFiles forum posted a work in progress of an amazing replica AS50 sniper rifle he's building. This pneumatic cannon goes above and beyond any air-powered rifle we've seen with an Arduino that is able to switch between automatic, semi-automatic, and burst modes with an LCD display and a rate of … [Read more...]
Atmel's XMEGA series of microcontrollers are neat little pieces of hardware; with a very fast clock, a ton of IO, USB, and up to 8 UART ports, these neat little chips serve as a nice bridge between AVRs and PICs and the very powerful ARM chips coming out on the market. Unfortunately, the XMEGAs don't use the extremely common ISP programming header found on just about every AVR dev board making … [Read more...]
Let's say you need a way to make a project wireless, but don't have the scratch for a ZigBee or its ilk. You could use IR, but that has a limited range and can only work within a line of sight of the receiver. [Camilo] sent in a project (Spanish, translation) to connect two devices via a wireless serial connection. As a small bonus, his wireless setup is cheap enough to create a wireless network … [Read more...]
In case the Realtek RTL2832u-based USB TV tuner dongle isn't useful enough, the folks behind a project to get a software defined GPS receiver off the ground successfully plotted GPS data in real-time with this very inexpensive radio. Previously, we've seen these dongles grab data from GPS satellites - useful if you're building a GPS-based clock - but this build required hours of data … [Read more...]
