Parts ordered from eBay.
Use the following lines to search for the components I used in the video:

"ZVS induction heater 1000w" - Induction heater with fan, 12-36VDC, 20A

"Switch power supply 24v" - Power supply, output 24VDC, 33A

"buck converter lm2596 adjustable" - Buck converter. Used to drop the voltage from 24v to 12v to drive the relay & LED

"12v 40A relay" - Basic automotive style 12v relay (recommend buying a 24v relay because it would eliminate the need for the buck converter. Note: if doing the aforementioned replace the

1kohm LED resistor with a 2.2kohm resistor)

"1/2watt metal film resistor" - (either 1kohm if using the 12v buck converter, OR 2.2kohm if running the LED directly from the 24v PSU)

"push on-off latching switch" - basic latching switch

"5mm LED mount bezel" - used to mount a 5mm led to the enclosure

"5mm led red" - The LED I used was rated for 3.2~3.8v and a max current of 20ma

"8GA wire" - Insulated 8gauge copper wire (I used about 3meters (or 10ft) total length)

"c14 socket" - look for a C14 socket with an integrated fuse holder.

"5mm fiberglass sleeving" - I bought sleeving with an internal diameter of 5mm. Buy about 2meters (6ft) worth (its cheap)

"Split Conduit" - Split cable sleeving to fit over the 8GA cables that go to the handle (20mm or bigger dia, 1.5m long)

"female spade terminal crimp yellow" - Used to connect the 8ga cable to the relay.

"3 core mains cable" - I used less than 0.5m (1.5ft) rated for 240vac, 10amps

"cable gland PG9" - quantity: 4

Optional:

"5mm copper tube" - 5mm dia, 500mm long (1.5ft) I used this to make the 2nd smaller coil in the video
