Simple circuit using LCM555 timer for clock to operate SN54LV163A binary 1 - 7 counter which drives FFB3904 dual mosfets that control two rgb LEDs which, lastly, cause the owl’s eyes to glow with continuously varying color. Intended as a wearable pendant for little girls and daring men. Runs off of a 40 mAH LiPo. Added SMD switch for power on/off. Corrected package error.

$50.70 for 3 / untested, will update
Motor driver for big robotics; a slightly-improved clone of a Chinese design. Main difference: added option for 20/26 pin header for easier connection. ~40A, 36V max. recommended.
Probably insufficient heatsinking, but that’s what fits the dimensions I have to work with.
Due to large un-tented vias under each IC, this board may prove to be fully hand-solderable (and even hand-reworkable using only a soldering pencil of sufficient wattage, a solder-sucker, and a dental pick/needle.)
More revisions and improvements likely to come. Common system ground; does not use the +5v line input (yet).
