Building stuff for ya?

Hey there!

I'm not only a starting noob laser hobbyist, but I'm also an electronics hobbyist. (a pretty experienced one, but I still have a lot to learn )

I'm somewhat curious, anyway;



Would anyone be interested in stuff I can build for you?

Like, say, Plasma speakers, amplifiers, power supplies, things of that nature, basically, any electronic circuit/projects that you could think of.

Each thing would be built on a personal basis, so I'm sort of contemplating the price point since each would be put together + tested and whatnot at least for power supplies anyway... or, alternatively, trades, too would be nice.


If you need something built, write down a description of what it is and I'll see what I can do.

Stuff I can build:

ZVS drivers; $30 without a flyback transformer - With flyback, $40


Plasma Speakers; $50 (sorry about the price increase guys, flyback transformers are kind of expensive!)


Power Supplies; Varies, anywhere from $30 to $60 depending on specifications... some are harder than others!

Shipping costs are *USUALLY* around $11 shipped, so keep that in mind! (I use medium flat rate boxes for most projects, though some may fit in smaller ones!) Also, remember, I'm up for trades still!



Please Remember, you're buying from a HOBBYIST. I try to work on them as much as I can, but I can get a little busy at times...


I also try to include videos of the projects when they're finished so you can view my work.

Regrettably, I cannot provide wall plug in power supplies for anything I build. If I did, the costs for them would certainly skyrocket (+$30!), and I usually rely on whatever you have to provide power. 18650 batteries work great for plasma speakers, and you'll get a good 1 - 2 hour(s) of music time with them. You'll need around 5 in series though to get decent output! I can also help you build one (provide parts for free), if you have a suitable transformer for one. (you HAVE to be buying something from me though)


If you're buying something HV from me, I'm going to require a simple test from me to make sure you know what you're fooling around with... I'm not responsible in any way for any injuries as a result of using my work! HV electricity is extremely dangerous!

Work I've done before;

Plasma Speaker to Tech_Junkie : Plasma Speaker - YouTube
ZVS Driver to Tech_Junkie : ZVS flyback driver - YouTube

HV X-ray Supply to Sigurthr : Flyback Driver... - YouTube

Constant Current Supply to Mendnwngs : Constant Current Switch Mode Power Supply - YouTube


Hope you like my work!

I'm currently looking for a HVDC power supply in the neighborhood of 30KV @ 1mA. Only source I can find is from Amazing1 (Information Unlimited) @ $80 shipped. If you can beat that you'll have my business. I know full well how to make one but I can't find suppliers for parts at all. A simple MOT step up to multi-stage CW multiplier would suffice rather well as long as a doorknob cap at the ouput can filter the ripple/pulsation.

I tried pricing parts alone for the multiplier from mouser and ran over the price offered by Amazing1.

30 kv at 1 mA? I could build that pretty easily.

Would you like to take this to PM's?

Sure thing, just keep in mind it may be up to a month before I can commit monetarily to this project (it probably won't take that long though) as there are a few important things coming up over the horizon. Basically what I'm saying is don't go out and tie up any of your funds on this just yet, hehe.

I've already built a power supply for mendnwngs, and have yet to send it away to him. It's a constant current SMPS capable of 70 mA to 3.1 amps. http://www.youtube.com/watch?v=pKZJ0A47TDU

Whatcha guys think?

It always amuses me when someone labels themselves as an
XXXXXX Master....

I used to know a Laser Master (DAoO) that could build anything
for anyone...

In your Video your DMM is hooked up backwards...

BTW you never did respond to my post on your Super-Low-Voltage
-Drop-Linear-Reg Thread...:thinking:

I have a small RF driven CO2 laser tube that I can not power. From my understanding it requires 200 Watts of RF power @27mHz. The seller said he used a 200W linear CB amp. Also with the tube came..."balance coil/RF transistor assembly" for building the PSU.

Unlike yourself I know little to nothing of building such a PSU. Also I have run into a bit of trouble finding linear CB amps at 27mHz because it is a banned frequency in the US. The tube has a BNC connector, and if you think that building a PSU/controller for this is possible i'll put up some photo's of the tube and assembly.

1. I wasn't actually serious about calling myself an Electronics Master. I know full well that I'm not, and it was just a joke.

2. When you're taking measurements with a DMM it doesn't matter which way it's hooked up. The point is you're getting a number, and the only thing that it adds on when it's hooked up backwards is a negative sign in front of it.

3. As for the linear regulator, I built it, and reported what I found. I never did too many measurements with it, but I did use several different sources of voltage (4.5 volts, 9 volts) and the laser diode I had hooked up lit up the same exact brightness.

Just saying. ^_^

Are you a Degreed BSEE, MSEE, PHD?

If so, from what accredited institution?

If I may ask what work have you professionally done?

What technology companies have you worked for?

What commercial projects have you headed and completed?

Let me put it this way.

I am an Electronics hobbyist, and wish to become an Electrical Engineer.

I know quite a lot about electronics, and circuits, and building things, but as far as any credible experience from say, a company, or a professional corporation, I have none.

I am, however, in the second year of a technical class at a place called Erie County BOCES.

I didn't mean "electronics master" in the fullest term. Like I just said, it was a JOKE, and I didn't mean it seriously.

If it bugs you that much, then you don't have to get anything from me. I was just wondering if anyone was interested, since I do have some experience with building power supplies and various things of that nature.

Also, to 532 with Envy, I don't know if I could build that. There's a reason why CO2 power supplies are so expensive...

It would be extremely hard to get the 27 mhz drive needed to get the tube going. Even 2.7 mhz would be a bit difficult.

You're looking at big bucks there really. CB Linears are outlawed as there is a 4Watt maximum on that band. Your best bet would be to find a 10Meter (28-30Mhz) amplifier AND CW Transmitter (you need a transmitter to drive the amplifier). With the transmitter and amp tuned to the lowest part of the 10M band place a 50Ohm 300+ Watt Dummy load in series between the output and ground/shield (you'll probably have to open up the dummy load, so look for a "dry" dummy load). Short the "key" socket on the transmitter to get the transmitter to output RF and you should be good to go. Do remember you need a power supply for this equipment as well, something around >50AMPS @ 13.8V.

Off the top of my head I can't spit out prices for linears but a 10meter CW rig will be around >$150 used, a used 10M 200W linear would be at least >$300, a >300W Dry Dummy load would be ~$100 used, and an apropriate power supply to power both the linear and the transmitter/transceiver would be >$200. So you're looking at >$750 to power the CO2 tube. If I were you I would sell it on eBay for $100 and buy a nice chinese combo unit (tube and PSU) for $400.

...for HV, commercial, military grade and other electronic supplies that you normally are not able to grab. Nice limited selection of laser related material that you cannot find anywhere else. Located here in the U.S. I do not know if they ship internationally. I've Been dealing with them for decades.

Have fun and be safe!

I'm free to start building stuff again, just let me know!

I'm currently doing several projects...so I can't accept any more orders at the moment.

Can you fix blown subwoofers? I have two yamahas that I LOvED but a power surge killed them both. They power on, but no noise.

I could remove the component boards for cheap shipping...

My gut feeling is that there is probably some specific transistor or other component that is fried and the board I'd probably completely fine otherwise.

How big are the boards? Pictures do pretty decent justice.

I've been keeping Le Quack pretty busy lately and he's just finished one of my orders. I figure I'd treat yall to the video showing it off:
