This is an IBM PS/2 to FlashFloppy (Gotek) media sense supporting adapter useful in more modern IBM PS/2s from model 70+ machines.

Power Supply Load management PCB

IceTube Clock sidepcb from Xmas icetube Rev D. Modified board vertical size for proper trace routing. Improved signal trace spacing and width, increased AC1 and AC2 trace width to support 85 mA current with less voltage drop. Removed unused mounting hole. Part of IceTube Clock main voard Rev. 2.2. Sidepcb Revision 2.2

IceTube Clock sidepcb Ver. 2.2

IceTube Clock mainpcb from Xmas icetube Rev D. Modified component placement, trace width, and routing. Removed GPS battery connection pad. Added component values to top silkscreen. Improved ground-plane coverage. Added C12 bypass on IC5 (LM317), changed R4 from 5.6K to 10K, improved component value silkscreen. Improved ground and power trace width, increased Awake trace width, improved ground plane cutout for battery holder. Increased trace width for segments 1 and 9, increased DQ trace with for IC4 temp sensor. Changed IC3 footprint to TO-220 vertical which supports both footprints (78L05). Changed R4 footprint to a smaller 0204V vertical footprint Increased AC1 and AC2 trace width to support 85 mA current with less voltage drop. Revision 2.2

Cybel - simple voltage controlled current driver

This constant current module will take 10-18VAC (eg. model train track power) and output DC to drive 12V LED strips. Flicker-free operation and DCS signal protection. Brightness is controlled by R1 (recommend 27-47 Ohms, minimum 22). Circuit design by John Will, board layout by Rod Stewart.

For Reading Voltage 0 - 25V to an Arduino Analog Pin

A normally closed reed switch indicating when the glider’s landing gear is retracted. This PCB and associated magnet is positioned such that the magnet is in close proximity to the reed switch when the landing gear is in the retracted position. This gear warning PCB works in conjunction with the spoiler warning PCB.

A normally opened reed switch indicating when the glider’s spoiler is deployed. This PCB and associated magnet is positioned such that the magnet is in close proximity to the reed switch when the spoilers are in the locked (i.e. not deployed) position. This spoiler warning PCB works in conjunction with the gear warning PCB.

This board houses the mod on the ds lite that allows for screen switching on the bottom screen. only parts needed are 6x6 tactile switches.

Idea thanks to makho’s videos/pictures covering the mod -
