Dangerous Soldering Iron driver V1.5(based on Arhi's gen3)

T1 should be NPN that can handle current for your backlight BC337 should fit the footprint and the use case perfectly
T2 should be PNP, since 1mA is going trough it really any one should do. BC327 should fit footprint

I wonder if it is possible to buy one of these boards fully assembled, or i have to source all parts?
Where can I buy the board and parts?
Thanks.

[neslekkim]

I'm buying piece by piece from ebay, almost finised now, just a couple of strangers missing.
have no clue at all if it will work or not..

@arhi
can i use any these for the triac BTA12-600BRG or BTA12-800BRG

and diodes 1N4003 with (1N4001) / 1N5819 with (1N5817)

is this the correct inductor for L2: 400361378383

thanks

I found the triacs here: http://www.ebay.com/itm/400360728432

@arhi

yes, they look ok

and diodes 1N4003 with (1N4001) / 1N5819 with (1N5817)

1n4001 is ok, 1n5817 is only 20V and you have 30V on the input so it will not work, you have to go with 1n5819

is this the correct inductor for L2: 400361378383

if your electronics is not going to draw more then 500mA then yes it is correct (it's all about what lcd you use, normal lcd with backlight will get you around 400mA, some good ones without backlight will go below 100mA but I have some lcd's that take more then 1A - you need inductor that's going to handle more then double of what you use). It's not expensive so you can try it out :D if it starts to get hot then you have to get one with more current. I use one just like this (1A)

[arhi]

with regards to triacs, I never seen triac that can handle less then 100V and since you are running 24V here, that parameter is not important... also, I never seen triac that can handle less then 2A and you need 2A for this so again it's not a big deal, gate sensitivity is also not too relevant as you are using external driver to drive triac (moc) ... so almost any triac you find will work, you really need to look hard to find one that will not :)

I have newer programmed an pic, what do I need to program it?, can I just use an ftdi cable, or do I need some special programmers?, if I need that, does it exists any cheaper ones that can program various pic chips?

you need a programmer (no, ftdi will not do), one of the best and cheapest is called pickit2, you can find pickit2 clone on ebay for under 20$ and it can program many pic chips (almost all of them, it just don't support the latest ones, if you want those too find pickit3 clone but that one is bit more expensive)

[neslekkim]

so the pickit3 can program the older ones also?, if so, it's only $30

If this one will work then?

there are also these:

[arhi]

yes pickit3 can program old ones, new ones .. it is also hardware debugger...

the deal with pickit3 is that clones are not that good (for e.g. that one from sure is known to now work in some cases) while pickit2 as way simpler device have no issues with it.

I can vouch for the Olimex pickit3 clone https://www.olimex.com/Products/PIC/Pro ... D2-POCKET/ but the price is not that far from the MCP original..

[neslekkim]

ouch, I ordered this:
http://www.ebay.com/itm/350637699036
and:
http://www.ebay.com/itm/251140525286
so, if that is know not to work, then are there any that are know to work?
checked mouser now, and the orginal seems to cost only €36 for this http://eu.mouser.com/ProductDetail/Micr ... NAcWahhP9A

that aint so bad if the clones are dodgy..i guess?

[arhi]

that zif board is perfect and very good build, as for the pk3 clone, I hope sure fixed the problem they had, if you encounter problem you can always ping them and get it sorted out ( http://www.sureelectronics.net/ )

Hi;
I have that ZIF board.
I had to remove the top cover to use it, you cannot get to the levers.
Also watch out for the pin 1 placement, it is diagonally opposite from the lever.
I marked mine in red.

It works well and is pre-wired for PICS, do not use with AVR's.
