Dangerous Prototypes Open Source Hardware

Hello All,

I have been following this forum for the past 3 years since it contains one of my favourite topic "soldering".
I am very happy to see a new version in 4 layers well done Sparky!!

I notice something crazy lately going on with ppl doing assemble for a crazy little amount of money like €72.

If parts are genuine there is no way to offer that price no matter what, there is no such discount on the market for new parts.

Just a little warning for anyone that is interested in buying assembled ready pcb since the only way someone can offer such price is by using FAKE or Worst second-hand components if that ever will be the case never blame this fantastic project but blame your budget.

I have enough parts left to assemble 20 Unisolder 5.2, doing it by hand is the best I found.

Keep up this project alive, I wish to offer my help in testing if needed, I have free time now.

Regards
Tronix

Q1 was dead as a dodo once replaced everything went alive.

thx xystwr as advised I focused on REF3030 and "bingo" one of the solder joints was not giving correct contact. Now it is showing ACF.  Calibration went smooth no issues.

I wired up my C245 handle and inserted my test tip and I am getting message that heater is open. I checked continuity between V1- and V1+ on my connector and this is correct. Any hint where to look for fault? I will be very grateful.

My enclosure has a hole for this, so I cannot move it.

This won't happen any time soon. I already wrote about my reasons. If someone wants to make a major changes/redesigns - the schematics are public, it is a day work to rewrite them in any PCB CAD and a week or so to make completely new PCB out of them. In fact a guy back in the thread did this, as far as I remember.

Сan you so kind to share gerber PCB file.

I don‘t understand why you need to keep down the cost of it, unless you just want to commercialize it.
The vertical Type-C connector is commen used, your point is irrespective of tech.
They are pretty cheap(0.1$-1$) and durable and have much types to supply, why not consider about them？
On the contrary, I deem that the biggest problem is that there are too many types to choose, even they can’t be found in other countries and places

A little question here, why not to replace mini-USB into Type-C in new version?
Thanks so much to sparkbg ; )

love diy, will you have any problems if I make the new revision 4-layer?
