z2uFlasher rootfs for 2.6.29 / OpenZipit

For those zipits stuck on the 2.6.29 kernel with the OpenZipit logo, your way to u-boot just got easier. It’s been too long without this but better late than never, right? This rootfs is just like z2uFlashstock but will boot on the 2.6.29 kernel zipit and isn’t huge like z2sid.

Getting root Access from Android Stock Recovery

This week a customer brought me a Verizon Samsung Galaxy Stellar (SCH-I200) that was freezing at the boot logo. They didn’t care about the phone itself working as they planned to turn it in under insurance. What they did want was their photos recovered from the internal storage. There are a few ways to tackle this and I managed to find a way I haven’t seen documented elsewhere.

VoCore Time-Lapse Photography

I’ve had my VoCore for around a month now and have been fiddling with them a bit. So far I’ve compiled my own rootfs (source now available in OpenWrt trunk), installed mjpeg-streamer, soldered some resistor legs to the VoCore for easier breadboarding, put a heatsink on the RT5350, setup a breadboard circuit with USB port and Logitech C250 webcam, and connected a SparkFun Power Cell for system load and charging a 12.6Wh LiPo cell pulled from an iPad 1st gen.

VoCore Arrival

The VoCore Alpha boards arrived last Saturday. I’ve been really busy this week so this is a short post with not much to report. The package contained 2 VoCore Alpha boards, 1 USB to TTL adapter and two sets of resistors. As I mentioned before there is a hardware bug in this version that causes the board to be unstable. Originally, Vonger thought it was because of incorrect resistor values (hence the resistors in the kit) but turns out the fix is to move a capacitor from one spot to another on the board. I did have time to fix one board, attach a USB cable for power and connect the provided USB to TTL adapter. The board has been up and running since Sunday with no problems. Check out some more photos…

VoCore: An OpenWrt Based Coin Sized Computer

Back in May I found out about an Indiegogo crowdfunding campaign for the Vocore computer. It’s a tiny computer (less than 1 inch square) with 10/100M Ethernet, USB, UART, I2C, I2S, PCM, JTAG and over 20 GPIOs running OpenWrt Linux. The heart of the board is a MediaTek 360MHz RT5350 paired with 32MB SDRAM and 8MB of onboard flash.
