The following instructions detail how to build a Solar Power Smart Head version 3. The Head will seek light and when it finds the brightest source it will go into a low current standby mode. This version also comes with an low power FLED circuit to indicate when the head is active.
The Turbot is a member of the Scophthalmidae family of flatfish and is almost completely circular. Turbot is often found partially buried in the seabed in sand, gravel, rocks and sediment. Its fat content varies, but it usually contains roughly 1 gram of omega-3 fatty acids per 100g fillet. Barring advances in genetic engineering, we will not be building that kind of Turbot. However, this kind of Turbot can be built with a soldering iron.
The following instructions detail how to build a simple pummer using a BC2 (Bicore) BEP (Bicore Experimenter PCB). A pummer is a solar powered self activating LED flasher. The difference between a pummer and a BLFNAR (blinky light for no apparent reason) is that a pummer has a soft turn off, which means that it turns on fast, but slowly fades away.
