Hi Julian Robert Murrey smith said he was making some supercap and he mentioned that you were interested in testing some, If you did can you let me know which video is covering this please. thanks
Did you say 600mm about a 60mm ic?
Why do they make them at 2.5-2.8 voltage? Why not higher?
Those caps are now 3X more. Ridiculous
I enjoy the way you explain all the items and why you bought them. thanks for all of your videos
I do like your Postbag videos. Time to celebrate the Julian's Postbag: #100 ! I'll be watching. Thanks.
if you were any kind of diabolical, you'd make a railgun! (gauss gun)
I had heat problems at 20Mhz clock with 4, linked 74161 counters. I solved problem with heat sinking. The carry pulse is only >50nS so it went to a F/F clock input to reload parallel counter inputs. My 1st big digital design of the 80's
5 of those Nippon in parallel looked indented when new then filled out hard and round after a week of charging and leakage when down to about 2mA! I found precharging in parallel is best in voltage steps to reduce power waste. See my other JI post for further details. I use a CV curent limmited supply to condition super caps. Always put new one in parallel when conditioning. I was frustrated by power wasted by the farad tolerance activating protection circuits in series cap batteries.
As it's probably already been mentioned, yes, those silicone plugs are pressure relief vents, so in the case of catastrophic failure, you don't end up with a huge explosion and aluminum shrapnel embedded in everything.
TLO84 found in almost every Hi-fi product made since 1976. Ubiquitous innit.
Thank Julian for subtitle!
Maybe you could spare one of the 10 bit bar graphs to use all 10 bits for one of the 8 bit computer ALUs – so that you can have a Carry, Owerflow, or similar flag on the 9th and 10th bar, +Julian Ilett ?
Much as I enjoy seeing you open stuff, I'd much rather watch you make the actual projects!
