Since my mower decided to die, I built a little battery charger since I had a free battery....sort of.

I've got it turned way down as those leads aren't going to take a lot of current, but it works. That little board under the DMM is a charge regulator I picked up at Tayda (though these are sold nearly everywhere)..thus the charger-on-the-breadboard. Unfortunately, the goop used to attach the heatsink was leftover PlayDoh from 1966, and the heatsink was loose in the package....also, it doesn't work so the heatsink isn't really an issue. I ran an audio probe through it, and it hissed at me :ROFLMAO:. The only thing worth a hoot on that board is the relay, which is likely what is FUBAR.🤷‍♂️

How can one learn such a power? The power of making a charger that is.

Well, for lead acid or gel, it's pretty straight-forward. Now, this is assuming you have a 15-18v power supply with enough current on tap. Call me lazy, but I didn’t build that bit.

Pretty cool site;


For lithium-ion and the ilk, it's a bit more complicated and I haven't done any reading in that direction beyond the realization that it would require more study time than I wanted to invest ;)

That said, solar charging and micro-efficiencies are of an extreme interest to me and I hope to have time to explore the tiniest of economies because that's where I'll discover the niche. (y)

I also got some extremely hard to find frequency splitters. Chuck knows all about them…high tech stuff really…:rolleyes:

…and of course there are games and puzzles for the kids…and drinking contests for the adults…all here at Fig Labs..oh wait, that’s the wrong promo text…crap! quiet…they are still readin…

I drilled an enclosure for it, assuming I’ll want to play it regularly, rather than on the FrankenRig™. I was out of A25 pots (of all things) so I was waiting to that so I can at least test it…I think it’s starting to believe it belongs on the bench. That guarded yellow eye with a smug & judgmental gaze…

Just checked…the A25s should arrive today so zippity do dah! :love:

Also on that order from Ross is a set of those nifty joysticks for joysticking things, and a bunch of 9mm for the set of SynchroTrems that came the other day. Yeah..I ordered two by accident instead of a Wah but I decided to use one for experimentation and the other to build stock. I’ll definitely pick up the wah on my next order though (y)

How do you test a pedal without soldering the pots? I have a few builds to test but I can't put the pots in as I don't have the drilled enclosures yet.

I tried using breadboard jumpers attached to the pots with alligator clips but the connection isn't stable.

Oh I don’t. Sorry if my post was garbled. :ROFLMAO: That said, I suppose I might be able find a suitable connector :unsure:

Unless it’s some weird layout, I sometimes solder the pots before the enclosure arrives or is drilled. Switches can be a bit of a pain..but I’ve had great success.

The Whipped Cream Drive I’m also building has all three pots and the switch soldered…I haven’t even thought about an enclosure yet..LOL

I just don't want to desolder anything. Even with the Engineer SS02 solder sucker, flux and wick, I still make a mess of the board.

My iron just doesn't cut it. I've just ordered the new Pinecil but it'll probably be months before I get it.

Time to design those enclosures and place an order with Tayda since painted 125Bs are unavailable in Europe ATM

Thank you! I‘ve got an upcoming countdown clock project with some Otis Elevator AN displays…it’s more of an actual project so I’m hopeful to have some fun with it.
I have a friend who works on Otis maintenance. I think more on the mechanical side. But let me know if you have questions, I can hook you up.

I forwent…hang on is that even a word? Apparently…anyway, I skipped testing and boxed the Phase II up, as I had a spare enclosure. I haven’t putzed with the trimmers or even put the cover on but with random pot settings it fired up and sound just like the opening of Bad Sneakers. :love:

I’ll clean it up and post a report. (y)

It sounded like an electric sitar? Make sure to take note of those settings because I want em 😍

I’m picking up a slight tick around 1Hz. I swapped the charge pump for another date series but same ting. At this point a reflow might be good, but it’s a slight tick (unless you probe IC6-1, then it thumps..LOL), so I’ll try an ICL7660 and maybe a MAX1044 just to compare before disrobing (y)
