My first prototypes actually had the knob on the side, and the input/output were on either end! I can pretty much put the knob wherever you'd like as long as nothing else is in the way. Shipping will actually cost more if I do the knob on the top, as it won't fit into a USPS small flat rate box...

ask and you shall receive! So here's one of my personal prototypes, using a screen that shows both volts and amps. I've since modified this unit and added a switch on the back, so it's pretty much identical to a VK other than the smaller case and the different screen. However, cutting out the...

Glad to hear it arrived okay and is working well with your dog! I'm really excited to be getting some of the first units out to customers! I just got in more screens, I still have to go through them, but it looks like I've got plenty of blue back in stock now, so you can now request blue again...

Hi everyone, to those who paid their invoices, your orders shipped today! Generally, Wednesday & Saturday are my shipping days. I've still got 2 units from the first batch left! I only have one red screen, so if you want red, claim it soon! I have plenty of green screens still available. Blue...

It's certainly possible. I can do 1-15v units pretty easily as it uses a standard value part, and I have some of those laying around if you wanted something like that. For a 8-9v range unit like you're requesting, I'd have to do some experimenting, but it's definitely possible, at the cost of...

Good question! I've decided I’m going to initially offer a 120-day no questions asked repair/replacement policy, but you pay the shipping costs. Due to the fact that these units can be easily abused by driving something too powerful and overheating them, and I have no easy way to determine...

Just in time for the new years, I've got a website for this up now: http://www.voltagekeeper.com/

Hey Alan, Thanks for the video and the review! It was a pleasure testing out the VK with all the various HI cores the other day! So people know what's going on in that video: When the unit is first switched on, it's in the "input display" mode, you can see the input from the AC/DC wall adapter...

Certainly do-able, would probably save me tons cost/labor on wiring the switches. However, I personally get a ton of value out of the screen being there, so that model wouldn't be for me! If there's enough interest in that, it's certainly something to consider. I think the $45 price tag is...

Hi all, After much research, testing, and back and forth with some various insiders, I'm pleased to finally announce the initial version of the Voltage Keeper (VK for short.) What is the voltage keeper? It's a voltage regulating device which can take nearly any input from 3-15v and output...
