Joe Ballantyne Store - For Sale Listings (2024)

[JoeBallantyne]

I am going to be offering a number of kits for folks who want to build one or more of the subsystems of the low cost fusor I posted about here: viewtopic.php?t=15444

The purpose of these kits is to help folks build subsystems as cheaply as possible, since they don't have to buy more than what they need, or pay for shipping for multiple different items. Everything needed to build a particular item/subsystem is included. Except of course the labor and tools required for assembly.

The first one which is available now is for building the low cost HV meter.

Here is the BOM and included parts list. At this moment I have 5 available. I will sell only 1 of each kit to any particular individual. All of these kits are sold at cost or current replacement cost. International shipping will be extra, and I will not ship to any countries for which the USA has export controls in place.

40kV HV Meter Kit

Micronta 50uA meter $12 ($142 / 12)
Project box $8 ($41 / 5)
1 gigaohm 50kV 5% 10W resistor $11 ($54 / 5)
1 meter 40kV cable $2 ($20 / 10)
1 gounding cable w/alligator clips $1 ($18 / 50)
HV silicone putty $5 ($20 / 4)
1 GDT 600V $2 ($23 / 10)
9" electrical solder $1

Total $42

Shipping up to $8 to USA addresses included

Price $50

If you are going to be using the 40kV precipitator power supply, and want to get the plastic storage container I used for immersing it in mineral oil, I will include it with the HV Meter Kit for an additional $5. I have 4 of the oil containers available.


D20 - Deuterium Oxide/Heavy Water - 10 grams. $20
This is from a NOS 1000g bottle of 99% D20 from Cambridge Isotope Labs that was first opened/unsealed about July 20, 2024.
I do not know when the D20 was manufactured and first packaged.
This is the same D2O I am using to make D2 for the low cost fusor.
I will consider selling larger quantities up to 100g for $2 per gram. I will not sell more than 100g to any single individual.


Please use the contact details in my profile to get in touch with me to arrange payment and shipping. I would prefer that you send email instead of a PM on this site. Calls made between 11AM and 9PM Pacific Time are OK as well. This does mean that buyers have to be registered members of this forum so they can see my profile.

Good Morning,

I am interested in purchasing the Deuterium Gas Supply Kit and 15ma meter kit, as I am making my first Farnsworth Fusor. What would be the next steps in purchasing the kits?

[JoeBallantyne]

Um, read the first post in this thread, and follow the instructions at the end of that post... that would be the next steps. If you are logged in, you can get to my profile, by just clicking on my name...

The second batch of MKS901p controllers designed by Phillipe David based on Finn Hammer's original board and code, was delivered last week and a few are now available.

Here are a couple of shots of the latest board.

For those who already have an MKS901p gauge, the board by itself is $15 plus $5 shipping for a total of $20.

I also have 2 of the original prototype boards that required a two wire modification available for $12 each shipped.

You can also buy the latest board with a tested, guaranteed working, zeroed MKS901p. This is an ideal, ready to go out of the box fusor vacuum gauge. It measures from ATM down to 1e-5 torr. (0.01 microns) I personally verified that these gauges work, and pumped each one down to its minimum pressure (1e-5 torr) and then zeroed it.

MKS901p w/Display

(1) MKS901p $100
(1) power/display board $15
(1) USB wall charger $2
(1) USB c cable $2

Total $119

Price: $125

Shipping up to $6 to USA addresses included.
