Thread: DIY Induction Annealer

haha, i doubt i can afford to reload enough to wear out my 40mm cases ( thats all 50 of them!)
but ill give it a honest attempt....

Video links are broken - put them on Youtube instead.

FAAA that's a few zombies and zombie trucks!!! I was looking at some 40mm empties at Wills Outfitters, quite a big pill really! 1/2 a can of 2218 each to fill?

Well that is snazzy and a half...... I am.... really impressed. Appreciate your posting the links to everything - I barely understand electronics but can usually copy it pretty well

i think its gonna be 1/2 a kg of b.p. each shot......$$$$$$$$$

I tried to get a revolving one going and the arduino electronics worked great but the mechanical feed and heating, just not. I have been thinking of trying something like this....

Hi @MGNZ, do you have an approximate parts cost for this? How is it going. no issues yet?

copper tube $5.95
coolant tank $11.26
radiator $10.80
48V supply $49.87
hose $4.34
pump $5.92
12V supply $3.58
LCD $3.21
ZVS $39.07
arduino controller $4.50
misc bits (jaycar) $50.00
Total $188.50 + a few other bit I had lying around.

see the Aliexpress links on my earlier post.

No issues with it so far. The capacitors get warm on the induction board after annealing about 50 cases in free run mode - 1 case annealed every 8ish seconds, so I just run 25pc batches then give it 5 mins to cool down before running more. The next addition might be to add a temperature sensor on the capacitors so that it automatically goes into a cool down mode when needed- like the AMP machines do.

I've been getting quite a few questions from members wanting to build an annealer like this one and most people seem very capable of building everything, but the electronic controller is the hurdle.

Now that we are all in coronavirus lockdown - I am going to have some free time and was thinking of designing a circuit board to sell to members at cost. The board will accept an arduino and will run the software I wrote for my annealer.

looking to see who would be interested in this to see if it's worth doing.

Couple of options:
- blank circuit board + shopping list of parts from Digikey that people can solder themselves (like a Jaycar kitset)
- Get the whole unit assembled in china

If you're interested, let me know what option you would go for.


* the controller is the circuitboard in the yellow box below.
It connects to the OLED display, 48V power supply, ZVS board, 12V power supply, servo or drop solenoid, 3 x buttons, pump, fan, (optional temperature and current sensors)

Well you've had a visit about 2!

I'd be interested in either option, probably leaning towards #2. Cheers

I'd be keen for either.

Well done for putting the time in.

I'd be keen on either, but #2 sound the simplest,

Rich

I would go either option

I would go with option 2 , thanks
