Fresh hacks every day
We find it interesting that PIC and AVR programming is very common in hobby electronics but ARM doesn’t have nearly the same foothold. This is partly because there’s a knowledge barrier involved with making the transition (the other part is probably the lack of DIP packaged chips). But if you’ve worked with 8-bit microcontrollers you can certainly make the jump … Read the rest
This hack came out so well that [Levent] wishes he had tried it years ago. When exercising he wears a Polar heart rate monitor which sends data from a chest strap to his wristwatch. But his exercise bike also has a heart rate readout that depends on your hands touching metal contacts on the handlebars. He set out to see … Read the rest

The price isn’t set for the device, but it’s … Read the rest
[Arshad Pathan] let us know about his latest project, a modular code lock that can be adapted to many different situations.
The user interface is made up of a character LCD screen and a 3×4 keypad. For this example [Arshad] is using a stepper motor as the locking mechanism. When the board is first powered up it runs the … Read the rest
Around this time last year, [Sprite_TM] took a 1980′s-era Macintosh SE and rebuilt it as a home file server. He used a Seagate Dockstar as the new motherboard, but over the past year he’s been annoyed with the fact that the Dockstar doesn’t have real SATA ports. Using USB to SATA converters on a server is a slow way of … Read the rest
In case you missed them the first time, here are our most popular posts from the past week:
In first place is a post about [Yves Rossy's] flight suit that he built that literally allows him to jump out of an airplane and really fly instead of falling with style.
Coming in at second place is one that brings our … Read the rest
