Mp3 Flash Recovery

November 16, 2006 by 10 Comments


[Bart] sent in his efforts to recover the flash data on a mysterious mp3 player he found laying about. He successfully built an interface using a AVR/ATmega setup to get access to the data. This could be a viable way to recover data from broken thumbdrives – but it’s probably easier to swap the flash chip onto another drive. The Chipquik stuff sounds interesting – cold SMD chip desoldering. Given the cost, I’m not sure just how cost effective it is compared to buying a rework station.

Design Challenge Mini-extra

Check out our new contest – design a business card PC board.

[Windell] sent in his tv-b-gone retro mod. [I want one that changes all the TVs to the SciFi channel.] He points out the ultra tv-b-gone as well.

[pillowcase] sent in his iTunes shower button – skip songs mid shampoo.

We heard about making a portable high power laser from a DVD burner laser yesterday, but the bandwidth was exceeded before we got there. It’s back up, for now.

[Mitch] let us know that a few days ago+ we appeared on TV in a lock bumping ad on Channel 6 WOWT News in Nebraska. Anyone else seen this?

Don’t forget that this site is driven by tips, so keep us in mind when you whip out the soldering iron.

Make A Badass CNC Mill

November 12, 2006 by 13 Comments


Ben Heck and I got into converting a mill to be a CNC machine during our podcast interview. Today I found a pair of great write ups at balbots on modding the Harbor Freight mini mill that I mentioned. Part 1 get into all the details of converting the mill to use stepper motors, and adding a cooling system. Part 2 covers upgrading to DC servo motors and replacing the gears with a belt drive system.

Bad Boy Charger

This is one of those hacks that scares me a little bit. The ‘Bad Boy’ charger was created by Tom Martin to charge EV battery packs. [Pictured is one built by Mike Chancy] You can find the schematic under austinev’s tech files. This thing is a bare minimum power supply – it’ll deliver loads of essentially unregulated power into a set of batteries. If you check out the circuit, you’ll see just how scary this thing really is, but according to its users, it works.

Ben Heck Interview Part 2

November 10, 2006 by 9 Comments

Here’s part 2 of my interview with Ben. (Or just grab it via the feed) We answer some more questions and go off on a few tangents about cnc machines, the PS3 and part sources. It cuts directly to the interview – I don’t want to wait 6 hours to record it. I should have a regular podcast up in the next day or two.
