Laser shutter controller board

A cheap, open source, RC Switch made with an ATtiny45/85. Based on the project located here.

Rotated the position of the IC’s on the CoCoEPROMpak 4k-64k EPROM-based Cartridge for Tandy/TRS-80 Color Computer.

Dumb tool board for Jubilee Baby Bullet.

Tested with Baby Bullet + Orbiter 1.5 + E3D V6 Groovemount Heatsink

Uses Molex Micro-Fit 3.0:

• 1x 430451200 12p right angle for input from controller
• 1x 430251200 12p Housings to plug into this board
• 12x 430300007 Crimps for above housing, order extra just incase
• 2x 436500200 2p right angle for Temp and Fan
• 1x 436500227 2p straight for Heater

Molex KK or compatible 2.5mm, also need matching housing and crimps:

• 1x 4pin right angle for stepper
• 2x 2pin right angle for PFan and PFan2 (2 Part Fans)

Dumb tool board for Jubilee Baby Bullet, Revo Micro.

Tested with Baby Bullet + Orbiter 1.5 + Revo using files for E3D Threaded Heatsink, before there was a version created specifically for Revo Micro.

Uses Molex Micro-Fit 3.0:

• 1x 430451200 12p right angle for input from controller, also need matching housing and crimps:
• 1x 430251200 12p Housings to plug into this board
• 12x 430300007 Crimps for above housing, order extra just incase
• 1x 436500200 2p right angle for Temp
• 1x 430450200 2p right angle for Fan
• 1x 436500227 2p straight for Heater

Molex KK or compatible 2.5mm, also need matching housing and crimps:

• 1x 4pin right angle for stepper
• 2x 2pin right angle for PFan and PFan2 (2 Part Fans)

v_0_3

• Made lower section narrower for threaded heatsinks version

  v_0_4

• Fan switched to 430450200, for Revo micro, use v_0_3, or v_0_2 for v6

AI BC2 Solid-State Switch

ORDER .8MM FOR BEST FIT. A simple pcb to add s video fuctionality to a model 1 genesis without turning the console shell to swiss cheese. It has an optional subcarrier circuit reroute to reduce jailbars for all video outputs. The connector goes ON TOP of the motherboard, it is a kmdgx 10s bs 10 pin connector so you will need to use a sega saturn s video cable for this. Untested so let me know if it works right but it should be great. the resistor on the luma line (pin 16 pad) is 27 ohms, the transistor on that line is a 2sc4617tlq npn. The resistor on the chroma line(pin 15 pad) is a 75 ohm. The cap on that line is a 3528 tantalum but could probably put a can electro if wanted, positive side facing the pad. For the subcarrier line, first component is a resistor 10k ohms, second component is a capacitor .1uf, third component is a resistor 1k ohms, last component is a 100pf capacitor, all components(including the 2 resistors on the luma chroma lines are 0603 size). to install: first place the connector on top, then solder the pins and flushcut them, then tape the bottom to avoid shorts. then remove the rf box on the console, then add caplegs to the top ground holes on each side, then add a capleg to the rightmost hole for 5v there are 3 round holes it will be the right one but check continuity to a 5v spot to make sure you got the right hole. Then place the board over the rf area and solder down. Pull chroma from pin 15 of the cxa1145 encoder, luma from pin 16 from the encoder, and audio left and right from either the headphone preamp or the headphone jack. For the optional subcarrier restore (recommended) lift pin 50 of the vdp(video processor) and run a wire from it to the pin 50 pad on the pcb. Then run a wire from the pin 6 pad (pin 6 pad next to audio left and right pad for va2-3, pin 6 pad next to vdp pin 50 pad for va6 ( next to it to pin 6 on the cxa1145 encoder. Recommended to remove at least the .1uf cap on the bottom of the board leading to pin 6 on the encoder or all 4 components on the subcarrier line for best working.
