valerionew / unisolder-notes Goto Github PK

I propose to start to work on an Wiring porting for Esp32 mcu, with Ota+wifi+bt future expansion.

Hi,
I'm planning to assemble a unisolder unit and I found your notes very useful, especially the BOM.

I just have a small question: I did not find Q10 and Q11 listed in the Excel file but there is instead line 112 specifying two IPD031N03LGATMA1 as IPD053N08 equivalents.

But looking in the IPD031N03 datasheet, Vds(max) > 75v requirement is not met... Has this line to be corrected with another mosfet?

Thank you,
Nicola

Was having a lot of problems getting a rotary encoder to work. Finally found this note, buried in the thread. Would be nice to put this into your notes so it's more easily found.

Information was found here in the main thread:
http://dangerousprototypes.com/forum/index.php?topic=7218.msg71747#msg71747

The control method is selected this way:

• go to menu
• press and hold center button ot encoder button for 5 seconds
• pres and release center button to select the control option
• leave it alone for 5 seconds and it will exit

The meaning of options:

• KEYS - the plain old 3 button control
• ENC-A-1PPD - encoder with channel A event, 1 pulse per detent
• ENC-AB-2PPD - encoder with channel A and channel B event, 2 pulses per detent (one for A and one for B)
• ENC-A-2PPD - encoder with channel A event, 2 pulses per detent
• ENC-AB-4PPD - encoder with channel A and channel B event, 4 pulses per detent (2 for A and 2 for B channel)

Just select what works best for you. The goal is to select an variant which leads to change of temperature/option with one up or one down per detent.

There is a connection picture here: http://dangerousprototypes.com/forum/index.php?topic=7218.msg74587#msg74587

For replacing U10 (original: MCP4651-503 (50k)) and U15 (original: MCP4561-503 (50k)) it's recommended using the same part MCP4561-503 (50k). But the original parts are different and it is even stressed in the description that you can't use the same parts for both.

Is there a typo in the replacement recommendation?

I was just looking into different irons and ease of the system to control the heat.
does anyone have data on which controls it's heating best?
i've seen a marco reps video on the jbc 245 it seems good but the heating and thermometer lines are double use
is there a smarter one to use?

I'd post this to the forum, but I'm not getting the verification emails when I sign up, and no one has responded.

I'm trying to calibrate my unisolder. When I go into the calibration menu, the R value is sitting at 35 with the 10 ohm resistor attached. I can turn the trimmer and have it go up to 40, or down and it goes to 30. If I disconnect the resistor, the value shoots up to 1100-ish. Reading the docs, it is supposed to be close to 1000 with the 10 ohm resistor? I tried searching through the forums, but I didn't find anything that solved my issue. I found some things that mentioned the current across Sense A and Vout1- should be around 380uA, mine measures 360uA (though I don't fully trust my multimeter). I double checked U11 was soldered on properly, as well as the PIC, but I haven't been able to figure it out. I even replaced Rc2 thinking it was a broken pot (original spun infinitely).

Hello, I was in the market for an upgraded station at home and stumbled across this project. I would like to do some design changes to make it easier to order mostly pick and placed. I am not looking to take the design as my own or profit off of it, in fact I am more than willing to share all files 100% every step of the way. I just finished the front board schematic into KI_CAD as it is my preferred software at work (only other option is PADS and I cant stand it anymore). if anyone would like to assist (and sparkybg approves) I would appreciate help finding new more available parts for the BOM. if there are software designers out there interested in implementing any new features but require edits in the schematic i am happy to incorporate those edits. I will be purchasing these from JLCPCB and just hand solder all the through hole components as required and will be more than happy to send off samples to anyone looking to add those software `integrations.

my first step is going to be just making replica schematics so if anyone wants to double check the connections. then I will begin to edit the schematic to relevant and more available parts either splitting diodes/op amps or joining them for example. I will be changing the regulator to newer IC something most likely with a higher switching frequency i prefer TI based IC's so I can use the webench designer for simplicity. please any input or requests i am excited about this project, and if nobody else chimes in I will at least be laying out my own board
Thank you

I've tried multiple things, but the board won't program. I've powered it via the power supply board and everything. The programmer always errors out, saying it cant detect the appropriate voltage level. Any ideas on troubleshooting? I can upload pics of both boards tomorrow, but I'm pretty sure all the components are oriented correctly.

Is the board supposed to have power when you're programming it? I have the PicKit3 plugged into the controller board and nothing else, and it's failing to program.

Hi,

I was considering adding some talk about possible enclosures and how to build them. I don't know if there is much information regarding this topic in the thread. I've seen some aluminium extrusion enclosures, some 3D printed ones (like yours) and a few others.

What do you think?

Hey, I just have 2 very simple questions.

1. When are you planning to release the case schematics?

2. Can you estimate the overall price of the pcb components?

Thank you for all the work!

I figured out which pins were which on the power supply board, but now I need to figure out where they plug into the control board. I can't find anything about how to hook this up, pin 1 isn't labelled in any way.

No trace of Q10, Q11 on https://github.com/valerionew/unisolder-notes/blob/master/BOMs/Unisolder%20BOM%20TME%20Farnell.xlsx

This is serious.

Hi everyone,
I see that some of you are continuing the work in some forks, doing a great job of expanding the documentation.
In particular:

• @lauer2356's fork
• @rsre's fork

What do you think about merging all this information in the main repo, adding a credits/contributors section?

How to make support other accessories like desoldering iron on brand Weller like DSX 80 or JBC
