Big thank you to all of you for your help and your time !! My bad for this stupid mistake.
Polymer elected as winner
If you comme in south of France I give you one of my own brewed beer or two !!

Congrats and good spotting that easy to over look issue.

Thank you Lord for sending Polymer to rescue us from eternal flyback pulse damnation.

Orange, orange, orange turned out to be a rotten apple! Haha.

All hail the rotten apple

I'm so relieved that the problem was found out.

I'm presently working on some mods to my Minipulse. Trying to add a new VCO circuit to give a nicer tone in the ear noodles.
If my experiments are good, I will upload the circuit mods.

impatient to see the result

No more than me I have just finished the work, your relief is near !!

Polymer I use this one [ATTACH]50227[/ATTACH]
Is a bit thick but they had not thinner wire at store.

You did quite a good job considering you used lead-free solder and a 30w iron.
I use 1mm solder myself for these projects and its ok for me.


Rothenburger is a well known brand, but more for copper fittings and such.
I dont trust solders that do not state what the alloy is or which fluxing agents they contain.


A few things you might want to consider if soldering some more through-hole boards:
- Do try solder with lead like Sn60Pb40 or similar. It will be easier and better results.
- Brands like Stannol, Felder, Balzer, Alpha, Kester, Edsyn etc. are fine.


Spending more on a great solder is well worth it.


It can be difficult to get leaded solder in Europe as an end consumer now.
Local shops sometimes still have good stuff and will sell it to you.
Online shops not so much - but auction sites will, from private offers.

Thank You!

I would feel honoured. Home brewed beer from a Frenchman - where they supposedly only drink wine. Cool.

I might take you up on that offer one day, being in and around Europe for the time being.

Are you on the Atlantic or Mediterrane side of southern France?

Cheers, Polymer

Yes,yes, yes, that is sweet music to my ears ... hope it works out.

That just reminds me of a song from the 70s. "Turning music into gold" by John Stewart.

Hi Polymer
I live in Toulouse right now, the pink city like we say in France. It is between sea and ocean and near pyrenees mountains.

I have already ordered a small wireless soldering iron and lead wire on aliexpress. I hope they will be good, they had very good customer reviews.

Hi Polymer

Just looked up why Toulouse is called the Pink City. Wow, would never have guessed this - pink bricks - with iron oxide.
Would be interesting to see if and how much your MPP PI reacts to them.

Do post your experience with the wireless soldering iron and if it meets your expectations. Why did you chose a wireless one if I may ask?

You might be lucky with the leaded solder from Alibaba. If it does not wet the solder pads very well or smells strange ... oh, well ...

It will be hard to take a brick from a monument incognito But if I found one i will try.

I will see with the leaded solder... By the way with my huge experience I probably will not see any difference.
I bought a wireless solder because I do not have many place to work in my flat and it's hard to find an electric plug and a the wire is anoying to me.

Yes, yes, everyone will notice the hole live on webcam " ... another brick in the wall ... not where it should be"

Fair enough about the soldering iron. Silly me, I thought of a WiFi powered soldering iron or something like that ... duh ... I realised I have a gas powered one myself ... I rarely use it.

Hi, I would like an explanation about the depth of exploration of mpp rev e, or a test video, thank you.

Hi,

If you are interested in building the MPP Rev E, I did a series of step by step videos that you might find to be helpful. You can find them here:
