Boards 08

Photos I have of the random things I put together this year, since we're nearing the end of it.

First up:

This is some level shifter and 3.3v regulator combo, It's intended purpose I don't really remember. Uses Maxim components. I ended up using just the 3.3v reg part of it. PCB was made with PnP Blue, and perma-marker

This is a board for 4 TIL311 displays ics(shown left), it's still sitting in my drawer, with TILs soldered in. Same PCB making method, this is going to be the same for everything else as well.

---

This is a single cell LiIon charger. Uses a Linear tech. charger ic (on the left) It was left over from the samples I ordered for repairing the Zipit1s

---

This is a lead acid smart charger board, that I never finished from here.

---

This is a lead acid battery desulfator from here.

Now this is a SPI (bios) flash programmer. It's based on this one made by Sergey Kiselev It uses a 74HC04 instead of the CD4049. I've only multimeter-tested it sofar. Built it for a mis-flashed motherboard I bought on the cheap. Still waiting for C2D prices to fall, so I've shelved this along with the mobo. (I'm a cheap bastard)

Okay this is.. modern art! Functionalitywise it's a low power step-up transformer. (really)
