Dangerous Prototypes Open Source Hardware

My Unisolder is almost ready and i would like to show you. Design is inspired and adapted from this post.
The area where the acrylic glass (also have it in lighter shade) sits on need to be painted or anodizing black. Because of cost i prefer to paint it by myself.

Let me explain what is happening when I connect no iron it work as it should, I can change temp to any value.
I can enter in menu with no issue. When I connect the iron it remain COLD, on screen it will appear 511C and rapid switch to sensor open and goes back to 511 C at fast rate (200MS) in a LOOP. I still believe the issue is on the front pcb but honestly we did nothing for this to occur in the first place and we also have no clue what to buy and remove next without replace everything. The iron is set to 340c but it get override with 511c not sure if that is the MAX set in code. It can read my Iron when connected using T12.

Thanks.

may I ask what cleaner you use please?  Which Mosfet shall I try ?

Anyone who wishes to have this printed, please find files attached to make it easy.

Thanks for sharing.
As I thought that is very narrow my toroidal transformer won't even fit in 101.50 mm x 101.50 mm.
With €9.70 I have enough Aluminum to make 8 Front and 8 Back.

WOW, the price Total: $136.30 + $42.75 for 1, hard to justify that but as I already said the end result looks nice.

1. Program it with latest bootloader.
2. Press the button of the encoder.
3. Switch on the power.
4. Within 1 second release the button.

Entering bootloader mode with both left and right buttons pressed while powering up does not work anymore, because of the encoder support.

Keep the encoder button pressed down and power on.

Some people here have had good success with a 50 cent mechanical encoder, while the ones I received were decidedly "meh". I also purchased a 30 dollar Bourns optical encoder and I actually do not like it very much either, as it's push button has no clear click, and it has an annoying rattle when turning it. I also have a CUI devices optical encoder en-route, as well as a couple of ALPS mechanical encoders. I'll share my impressions of those when I have used them for a while

I think your best bet is to order a couple of cheap mechanical encoders and see if you get along with them. As time passes, more and more users will be sharing their experiences with different encoders I'm sure, and you will be able to make an informed decision then.

Its a good and cheap solution as you say   But the problem is that i already have WXDP120  .
In first coarse wxdp 120 iron heating test (witch lighter and two multimeters) i reached Resistance and Temperature values equal to PT1000 probe table values in range 30 to 300 degrees of celsius (ofc with little deviation).
Which profile will be best to remake to WXDP120? Also rest of aboved profile will need to be changed :c How to beat that?    

Very nice idea,
When do you say cheap what value since I am interested?
Weller is far from cheap a simple tweezer will cost your bank 

I did research from my supplier:
1> €128 for the Heater.
2> €146  complete (Just with handle iron).

Hello Unisolder friends 
Im very happy user of Unisolder station since last week I solder 10 pcs of it with Weller WD1 and WSP80 (horrible but not impossible).
Recently i tested it with Pace TD100, Weller WSP80 and JBC245 irons.
I would like to connect it to Weller WXDP 120 (same like ppsati in post #359, directly to iron and sensor of course) and make desoldering station. Could You help me with my problem?
I want to ask also great sparkybg, maybe would You write some FAQ for begginers (like me) how to create own iron profile, wchich will describe where in code (iron.c?) and how use PIC software to change  iron.c parameters, how found parameters to paste (for example touch to another iron/i mean soldering station like weller/ witch set temperature for a while and read value on unisolder?), compile it all and send it via usb to Unisolder 5.2?
I try to understand iron.c, but i see only a equation with constans (parameters) that i dont understand.

PS. Sorry for my English and for my stuppid questions wchich may be very easy for many of you.

1. Upload the latest version
2. if PS is 24V, subtract 1 diode drop (0.5 - 0.6V for Schottky at this power), then multiply by 0.95.

(24-0.6)*0.95 = 22.23V. 22.23/7.2(the heater's resistance) = 3.0875A. 3.0875A * 22.23V = 68.6W.
