Most "Radio Ham's " will be able to do the job. And they are "all over the world" and generally not di...

Future PSU designs

Hello Exxos, If I see it right, there's 3 primary windings needed. Or maybe it can be done with 2. 3 windings: 115V, 115V and 10V. All series = 240V, 2 x 115V series for 230V, 2 x 115V parallel, obvious. Or maybe you can get away with 2 windings of 120V. Now if you have those windings made such that...

Re: MegaST 4 will not boot, but looks fine with diagnostics

Finally, I found some courage and inpiration.
And solved the problem.
Jumper W2 had a bad contact.
But it was hidden below the body of the part.
So there was no or a bad connection from the decoding chip to the Eprom.
The board works fine again.

Re: My weekend sorted...

Have replaced the sockets, now two quality sockets with round contacts are in.
Still with these it doesn't work either. :( :shock:

However it was a very good idea. :)
