Edited to add: I am using pickit3 to power it with 3.375v. Error is deviceid (0000000) does not match expected deviceid. Obviously the target is not recognized. Do I need to increase the voltage?


I finally managed to flash the PIC12F615 by installing and using MPLAB X IDE 5.10 instead of MBPLAB IDE 8.92 which I used to flash the bootloader of the PIC32. Strange, but stuff happens I guess.

Thanks for the feedback!
This is not the final board, more a prof of 'everything working'.

I have thought about mounting holes but I wanted to hear from you guys where and how many.
As I have planned this board is not to be a front panel, rather solder wires to buttons and lcd, and the
board can be placed anywhere. The USB-connector is a 'standard' one.

Yea U11 and U15 is.. hmm gotta think about them..

It's alive! Still with some bodges and not all components :)

Maybe someone is interested in some of them...


I am interested!

I'm curious if Unisolder supports Hakko FM-2032 micro soldering iron with T30 tips.
This iron is intended to be used on FX-951, FM-203 or FM-206 stations.

I think the UniSolder project is really great but It's too time consuming to buy all the components individually. Is anybody selling all the components & PCB in a package or the final product?

How should HSEL signal look like in a oscilloscope? A square wave or something similar?

On my scope it appears more like random noise.

I ask because I managed to build my unit, calibrate it with a 10 Ohm resistor but now, after soldering the correct resistors (I checked) for C245 I get "NO INSTRUMENT" message. In the calibration menu it is shown "IRON ID 5 5" instead of "IRON ID 24 5".

I suspect something wrong with the HSEL signal.

Check please: U5/ pin30, R24-1k pullup, and its connection to ID pin
and if ok reprogram controller

I am currently assembling my station from the same group buy parts. Have to say that vulcan35 put impressive efforts in selecting parts for the kit (the quality I mean). I measured resistors (I installed caps and resistors, moving to diodes and small sot 23 parts), though they marked as 1% ones, my UNI-T UT181a shows close to 0.1 % tolerance. Also, he tested all parts from the kit before sending to group buy members.

Reading numerous posts concerning whereabouts of some rare parts, I decided to skip 'search and find' mission in this endeavor :) and looking at the number of parts, I am glad that I did it (or maybe because I am lazy :))).

There is 1k between U5/pin30 and pin 1 (ID) of connector J6 in the back board.

I also checked continuity between U5/pin 3 and U2/pin 2,4 of the back board (HSEL signal).

I reprogrammed U5 again (with bootloader + pc software method this time, previously I used the standalone one) but it didn't solve the issue.

Still "NO INSTRUMENT" message.

Should I try to change U5 (or U2)?

Just assembled back board (power supply).

I tried feeding DC and AC as well, on J3 I am getting 3.23V and -0.53 V (as on the photo well circulated on this thread). Current is about 7 mA on 24V, dropping down to 4 mA on 9V (using DC input). The second (negative) voltage on J3 is dropping at 9V to -0.3V (or something lower than -0.53V). If I used AC via a transformer (which feeds 26.6 V), I am getting the same voltages. They should be 3.3 and -0.6 V according to the scheme.

I also accidentally shorted 3.3V and ground pins (forgot to switch from current measurement on my multimeter) for short time and heard some chirping. Anything could be burned? After shorting I still get the same measurements as described.

I can suspect LM2675 (which could counterfeit one) for getting lower voltages than on the scheme.

Any ideas?

it should be, how to connect the front board it will 3.23V and -0.6V

I also checked continuity between U5/pin 3 and U2/pin 2,4 of the back board (HSEL signal).

R24 - 1k connected to U5/pin30 is pullup to 3.3V - one side 3.3V on the other U5/pin30 and ID pin/J6 together
HSEL is only 1 or 2 pulses at identification state, I guess, and after that controller decides to continue with low HSEL for 1 channel or pulses for 2 channels operating.
Just to be sure check resistance of ID line in respect to GND and to 3.3V for a short, of course without power.
