Well so far the retirement has gone well, ha ha, not a chance I have been more busy doing more designs than ever before. This include new cable idea and construction, so I decide to retire at 99yrs 364 day, just to keep busy.
I love walking and the last year that was not possible, that is due to my health state and has not been a good idea so into my pit I go now 7 day a week .
I have had few interest bangs I managed to blow up a 1600V 300A IGBT, the beast was 4 x 3 x1.5 inches approx and the smoke escaped blowing it lid off and the 5mm connector bolts.
Thank good I have few more, I was building a 400V 100A charger. Clocking at 50KHz I only had to find lots of mobile phone bats to make it work. I need 80 of 5V 2500mA per Cell block and I need 50 blocks. So has any body got 4000 mobile phone batteries?

It did make a very loud bang I hade ringing in my ears for hours. And the smoke was blue, funny that, the same colour as my swearing.
