Pushing FPGA config files via serial using ‘cat’

[Andrew] is trying to buckle down and hammer out his PhD project but was surprised by the sorry state of the configuration options for his FPGA/ARM dev board. Using JTAG was painfully slow, so he studied the datasheet to see if there was another way. It turns out the Xilinx FPGA he’s using does have a slave serial mode so … Read the rest

Nuclear Taco helmet measures reaction to spicy food

Apparently there was a Nuclear Taco eating contest at the 2010 Codebits Conference. The team from altLab, a Hackerspace in Lisbon, didn’t partake but the discomfort of those that did was burned into their memory. This year, the altLab members decided to build a spciy taco monitoring helmet as part of the conference’s 48 hour hacking competition.

The helmet was … Read the rest

If you’ve seen videos of industrial robots on automobile assembly lines and the like, you know how fast and strong these machines are. But this isn’t headed for the factory floor, it’s a new flight simulator built do train Australian fighter pilots.

Researchers at Deakin University … Read the rest

Python powered sprinkler system wastes no water
