Colloidal silver heated magnetic spinner
you need to print this in abs because of heat bed. print at 100% infill or it will tear itself apart warping i put felt pads on the bottom in the four corners
Spinner
40mm cpu fan 12v
10x2mm magnets x2
M3x60 and aquarium tubing for spacer
heat bed ( http://dirtypcbs.com/store/designer/details/peter.plaaswerf%40gmail.com/168/100x100mm-3d-printer-heated-bed )
a proto pack is 12 of them if i remember right
the heat bed helps speed up Electroless in the distilled water
555 pwm x3 ( scamatic is in pics )
allows you to control temp and spinner speed also pulse on electrodes helps control particle size
There are some holes that need drilled IE to hold top on to mount fan inside and for heal bed
for 12v power supply i used xbox 360 power brick
You will need to modify the 555 pwm schematic for this project but if you cant see what needs changed you probably cant build the timer yourself anyway LOL.. It is the same timer you would use in a PWM box mod
the glass came from the Dollar tree and the coated magnetic spinner came from ebay
silver rods came from ebay only use 9999 silver
