Below is the 95% complete shopping list to build a functioning Induction annealer. Some additional items like screws, wire, solder, material for a housing etc. are required.
Total parts cost is approximately $200 USD for a basic build
Arduino Uno
Uno board
*You don't need this if you buy the MGNZ Control board complete with Pre-programmed Arduino Uno
Qty
1
12V Power Supply
12V, 24W AC-DC power supply
** Use 12V, 36W AC-DC PSU if you are using the automatic case feeder feature
Qty
1
ZVS induction board, 1000W
These come with a coil, but a new smaller coil needs to be wound
Qty
1
DC solid state relay
Must be DC secondary - select 25A or 40A. AC versions won’t work.
Qty
1
Solid state relay heatsink
A heatsink is recommended for high duty cycle usage of the annealer
Qty
1
1/8”(3mm) copper tube for coil
I used the 3 x 0.5 size. Thinner wall section to get better water flow
Qty
1
12V cooling fan
Any PC case fan will work. 80mm fans will attach directly to the radiator. Order 12V, 2 wire fan - either ball bearing or sleeve.
Qty
1
Silicone tubing for plumbing
Water pump, tank and radiator have 8mm hose tails. Induction coil pipe ends are 5mm OD. Some reducers need to be made / figured out.
Qty
1
Pushbutton momentary switches
LED current limit resistor is already on the controller PCB. Order 12V option.
Qty
3
Temperature sensor - Optional
This should get glued against the ZVS board capacitors.
Qty
1
Jumper wires
Connecting OLED, current sensor, temp sensor and Servo to PCB. Either get Female-Female option or the mixed lot. 2 different length – 100 or 200mm
Qty
1
Closed loop stepper motor
Used for automatic case feeder function. Purchase the option that contains Motor, control board, OLED, cable and breakout header
Qty
1
NEMA 17 stepper motor - optional
Used for automatic case feeder function. Purchase this motor if you buy the Closed loop stepper control board and the stepper motor isn't included.
