Fresh hacks every day
If you’re into all-grain brewing a little automation goes a long way. [Tom Hargrave] had his eye on a Recirculating Infusion Mash System (RIMS) but the price tag kept him from pulling the trigger. Recently he bit the bullet and built his own small and inexpensive RIMS for use with the 10 gallon cooler he uses as a mash tun.… Read the rest
[Berto] wrote in to tell us about the visual effects synthesizer he built.

ST Microelectronics keeps kicking out development boards to show off their new ARM processor line. Yesterday they issued a press release announcing the STM32 F3 Discovery Board. As their naming scheme implies, this carries an ARM Cortex-M3 processor, but compared to the F0 Discovery board (which we loved) it’s got several extra goodies built into it.
