Simple ammeter/amp-hour meter

I've just made an ammeter/amp-hour meter if anyone's interested. It uses a Tamura current sensor, a 16 x 2 LCD and a small pcb with a PIC micro on board.
The display shows Amps flowing through whatever cable you stick the sensor on and Amp-Hours accumulated since the last rest. The range is 0 - 511 amps and it measures about 82 x 41 mm. It needs 12 V power and is completely isolated from whatever you are measuring.
Parts cost is around $40 if you want to build your own or I can sell you a completed one - without case - for $99.
Send a PM if interested.

Sometimes I sits and thinks and sometimes I just sits.
