Powered by a CR2032 and using the WT51822-S4AT bluetooth module, this board turns the bluetooth module on when motion is detected via the AM312 PIR sensor. When not active the circuit draws about 10uA and 1.4mA when active. This allows for a beacon to operate for weeks off a single button cell battery.

Test jig designed to test an assembled Ruthsarian Blade Controller. The board is designed to test the assembled board upside down with the BB image on the controller facing up, away from the test jig.

• 3x 1.3mm diameter, 16mm long pogo pin
• 7x 0.68mm diameter, 16mm long pogo pin
• 1x 10 position, 2.54mm pitch header
• 4x 1 position, 2.54mm pitch male header

Suggestion for assembly is to add 1 male header pin to each corner. Then place a second board over the first, aligning it over the pins. Insert pogo pins through both boards to keep them aligned. Solder pogo pins to top board and then solder corner pins to top board. This process takes up two boards, which is not necessary, but assembly and stability will be greatly improved.

An 1606-based replacement blade controller for a Galaxy’s Edge lightsaber blade. The firmware and further documentation for this project may be found at github.com/ruthsarian/RuthsarianBladeController.

NOTE: this is version 4.1 H and is different from version 4.1 L. The two versions are similar except they use different LDOs for the LEDs (U2).
