I don't actually own a solo so I can't verify this myself, but from what I am reading, the solo needs either around 7-9v or 12v depending on whether you're charging or just using it for pass-through heating. The VK can definitely provide the 7-9v or 12v, the real question is how much current it...

Sucks to hear that other knob didn't work either. I'm still awaiting another batch of verniers that are a slightly different style, just to try them out and see if they're any better than my current ones. I still have a handful in stock so we're good to go either way for any new orders. I've...

Glad you're enjoying it! That unit came out nicely and looks great next to your HI's! I'm still wrapping up the next batch of units, I should hopefully have some more updates soon. I've also bought myself an organizer for all the parts it takes to make a VK - little things like this save me...

Yes, with the stock VK you need a DC source. Although, I could build you a unit with an AC rectifier in it if you wanted. An AC rectified unit would still probably work on DC power too, but it would be slightly more wasteful as it would be drawing extra power. Not what you'd want if you were...

I'd like to keep the idea open that it could be used for many lower powered DC devices, there's really nothing stopping you from doing so. When people ask me what I'm making, I usually tell them power supplies for any DC devices with those barrel jacks on em, and/or temperature controller...

Thanks for the kind words, and shh, you're not supposed to tell anyone about those feet! Hahaha, just kidding. I'm working on templates to make creating these mini VK's a lot easier, and I'm hoping I might be able to mass-produce them at some point soon, since they can't have any extra options...

The standard model goes from around 9v to around 15v. For the 7.5v range, I can certainly tune a unit to do something like 6.5 - 12.5v or something like that. However, another, and possibly better option, is to go with the 10-turn pot. With those, you'll get a full 1-15v range, without...

That certainly wouldn't be all that hard to do assuming I could find such a part. I could probably put real big feet on the back too if you wanted it angled like that. The viewing angle is very good on these LED screens though, so it's definitely not required to have it at an angle to use it or...

And here's the first top-mounted pot unit! With a 10-turn pot and a blue screen, next to vk#1 for comparison.

So, I've got the first "small and tall" the works unit done. This is something I've wanted to make for a while so I'm glad to see it come out so well. I decided to mount the screens in such a way that they're positioned over the multi-turn dial. It all works out quite well, due to the extra...

Ah, there's VK prototype #1! That was the first one I made that's functionally-identical to the current model and uses the same case, just had a very different layout of all the parts! It's recently gotten an overhaul now with the 10-turn pot! I used a spare knob from my 5u moog-inspired modular...

Yeah, even the standard unit isn't really that big, maybe a half inch wider and taller at most. Your unit is just tiny though! You're right though, the current design won't really allow for anything much smaller, and going smaller will likely mean a new board with a lower power rating, but still...

Awesome! I wish I'd had a chance to post a picture of it next to a standard-size VK, and some things for size reference (like that lighter!) I'd been debating a name for these, but miniVK is what I'm calling them now too, but I'm still trying to keep the idea open to get an even smaller unit...

The last image I posted, I showed the incomplete super-small VK. Here it is completed, the smallest VK to date. This will only fit a standard model, it won't take any upgrades at all, it's literally packed to the brim in that tiny case!

Hah, wow, you guys managed to find some really cool battery packs! That $17 4500mah is exactly the kind of thing I was looking for. Something where you don't have to charge the individual cells, you just charge the whole pack, and it's cheap! Very cool. I might try to see if I can find a...

I sadly won't be able to make the cup this year, but Alan will be there representing the VK for me. I would be down for some kind of meetup at some point though!

All the clear blue units shipped, including the first "the works" unit, which is exciting. With that, I've also got a few more clear blue cases in stock now, get em while they last! Still have to wrap up the real small clear one, it's mostly done, it just needs the wiring finished. I'll be sure...

Yep, that "the works" unit is packed to the brim, for sure! In fact, it required so much accuracy with the drilling that I'm really tempted to come up with some kind of CAD drawing that I can print out and use as a template, as doing them one off as I did on the unit above definitely takes some...

OK, you asked for photos, here's the first "the works" unit! I've also got 2 other clear blue units I've got on their way out. I've also got a new smaller clear case that's just barely big enough to fit a standard unit. One of those is still up for grabs, the one pictured is currently claimed...

Coming very soon! I have a few orders I need to really get done this weekend. I will take pics of those once they are done. I'm also thinking of maybe just making one of the smaller-case units for show/sale as-is, since there's really only so many options they can fit anyway, and I think a lot...
