ToyREP Heatbed PCB heatbed for ToyREP 3D Printer and other small machines.
This thing is published with courtesy of my friend Dan Kolar who designed this PCB heatbed and made the prototype board. It is just published under my account. Please refer to him as the author.
Working area is 100x100mm Mounting holes are 105x105mm apart. Total size of PCB is 120x120mm Copper layer 35um thick
CNC milled prototype depicted is probably a bit weaker due to fabrication process and final sanding. Originally it was supposed to be 36-40W. With etching you may get better results.
Parameters of the milled prototype are:
Resistance of heat bed c. 4.8 OHM Approximately 2.5A at 12V = 30W. Max. achieved temperature 116°C (at room temperature 24.5°C) in 15-20 minutes
Detected 2 layer board of 4.72x4.72 inches (120.02x120.02mm). $111.60 for three.

PCB to add Composite Video to Odyssey 2 console.
Please don’t make to sell on eBay, etc. This is for non-commercial use only.
Parts list:
CT6EP102 (1K pot)
BC558B
BC548C
680 ohm .25 watt resistor
220 ohm .25 watt resistor
100nf cap
You adjust 1K POT on this PCB and R4 (on the O2 system board) until you are happy with output. Default setting is 400ohms.
Video in = junction of C44 and R7 on system board GND = Ground +5v = easy enough to find with multimeter Audio in = junction of C45 and R49 on system board
Put RCA jacks on the lower left hand side of the bottom shell. This way they are out of way of system board and voice module.
