My PCB from Arhi finally arrived today :D almost 4 months later (Serbia you silly place :D) I cannot wait to build this up. Already placed another digikey order.

thanks Arhi

Im wondering; what is the minimal configuration? Like can I skip the DCDC circuit if I power it direct from a DC 24v? I noticed on Arhi's pics there was alot of little segments of the schematic un-populated. I would like (for now atleast to get it working) to keep it as minimal as possible then build on that.

Any suggestions?

YAY! Read this (again) for starters
viewtopic.php?f=56&t=2457&start=360#p35137
and this one
viewtopic.php?f=56&t=2457&start=360#p35531
Probably this one too, and it's link also. firmware is 2 posts below this one.
viewtopic.php?f=56&t=2457&start=330#p34700
I'll call this one the "assembly photo", and quit linking the other thread now
viewtopic.php?f=56&t=2457&start=330#p34847

Good luck!

That first link said the DC wasnt tested; but on the 'assembly photo' it is populated. So I can skip that part using a 25v wall adapter right? Do i need to jumper anything or can I simply plug it into the power connectors? (the schematic noted which one for - and +). Or was he talking the DC FET area?

The populated DCDC is for the board, yup. And the drivers are FET and TRIAC areas, yep.
You'll need to plug 5v in also of course, 25v DC only gets you past the transformer requirement.

you need DCDC any way you go around it, as you need 5V for the pic and op-amp and lcd.
you do not need the usb part (connector, diode)
you need to populate only one output driver, either DC or AC (optocoupler+fet or optotriac+triac). The DC output driver was not tested by me, but many tests with driving regular irons (weller pes51, hakko 907, solomon hq30...) with DC destroyed the heater in under a month!!! so I really suggest you stay with AC

Why does 24V DC destroy the heater while 24V AC doesn't?

I have zero idea why, but it happens. Someone on blog posted a comment on dp wrt this mentioning some electron migration... All I can say, from experience of few ppl running these AC handles on DC, is that - they die (usually break towards the sensor or towards the ground, less frequently - the heater itself breaks)

Its not for sale... Atleast not at this point. Its still a prototype; you have to win a FREE PCB code and get a PCB free (if there in stock). I don't know if Ian will decide to start selling the Iron driver or not.

@Ian; can you chime in? I would like to know as well. And if you are; can you estimate the price? Or better yet; the when?

I'd like to ask another question, I sent bunch of the pcb's out (one came back :( ) ... Ian made the v1.5 and afaik also sent bunch of pcb's out .. did anyone assemble it? did anyone tested it? tried it out? or are me and arakis only one trying it out?

Hehe, I tested Arhi's g3 it works as advertised :), Didn't get the V1.5 boards yet, and never got around to test the V1. :)

As far as sales, the V1 and V1.5 will never be sold as assembled kits. We might sell PCBs in the future but that is still to be decided, and no-one that I know of has built 1.5s yet, so we don't even know if they work :), although they should seeing as they are compatible with arhis gen3 boards :)
best regards FIlip.

Arhi, i received your pcb and as you know is working, is actually my official soldering station. I received before yours the DP v1, but i assembled half of it, and i'm using it like a 18f2550 developing board.
