Big thanks to Patreon supporters who make Postbag videos possible - Patrons got to see this video 2 days before anybody else.
This is a mini Postbag followed by some modifications to my 6x 120F supercapacitor module.
UPDATE: So it's 48 hours later and there's still 6 volts on the meter 🙂

Great project! I would like to do the same with my DIY.
SMDs suck! Youre not alone.
I have been watching your videos for over a year now. I need to order my first set of super caps. Any recommendations?
Julain, I was cringing while you attempted to solder that LED. Why not use flux? Watch Louis Rossmann , or Jessa while they repair Apple boards.
I'm going to seriously disagree with your comment about how the seller can't be held responsible for the damaged meter. The hell they can't! That was simply not packed properly, and if you were talking about a situation where a carrier had a claim filed that's exactly what they'd say…
I love analog meters.
Yes, SMD's suck compared to through hole. I now use a good pair of reading glasses while doing it. they help a lot! until the wife is talking to you and you look up at a big blur. lol
Don't feel bad about soldering surface mount they like to skid all about the board like hover craft. Trick is tin one pad (no matter the package type) and tack the part in place. Solder all the rest and re-flow the tacked solder point with fresh solder. Liquid flux or better yet flux paste is your friend as well.
Yes, surface mount is a pain. Looks like it's going to be harder to get tinker-friendly components, so I guess we'd better get used to them. (53 yo, +2.0 reading specs)
Thanks for the many videos. Do you have a diode to suggest that would drop about half a volt and could take 5 – 10A? It might be useful for a lead acid battery undervolt protection. Instead of dropping down to 10 volts (and ruining the battery), it would only drop to 10.5 volts.
For SMD led's (and many other SMD components) there's a really easy trick to soldering them. Flow a blob of solder onto ONE pad. add a bit of flux, re-melt it and touch the led to it. The liquid solder will suck the LED in and position it. Let the solder set, then flow the other side. Simple and easy.
SMT= Surface Mount Technology
Failing eye sight, twitchy hand……. I despise SMD's. If I were younger and healthier, I probably have fewer issues with using them.
Wait until you get to 70, then worry about your soldering!!!!
links for that 140F supercapacitor bank , thanks 😀
Sender IS responsible. They should pack things better. Bubblewrap is not expensive.
On a couple of occasions you said half an amp was going in but the display showed 0.2 amp. Good vid. Going to buy some super caps for a play soon, and it will be your fault. LOLZ!
