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…

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.

It’s a common occurance that the microphone will go bad on a cell phone after being subjected to liquid damage. The Samsung Galaxy S3 is no exception so I try to keep some on hand for when they’re needed. I’ve been buying them on ebay usually in lots of 5. Recently, I purchased a 10 lot at a good price but upon arrival I noticed the hole for audio input was different. The mic on the left in the picture above is an OEM Galaxy S3 and the right is the replacement I received.

Time’s are a changin’. Life has been so busy lately it’s surprising I’ve had time to redo the site. It’s amazing what you can’t find time for when you’re self-employed. Last September I was laid off from my regular job and decided to go on my own. Electronics are everywhere and everyone breaks them, someone needs to fix them. That’s what I’ve been doing for other companies for years, now I am my own company.

It’s that time of year again for an upgraded flash script. This latest version is the easiest yet and again will flash from stock to u-boot and back. As usual, the goods are at the bottom of this post. I’ve added some fancy new features like progress bars.
