I have passed links and info to wkp80 via the facebook page. Have explained the situation. re country restrictions.
Hopefully Kephra will pick up and provide up to date position on accessibility.

(I just posted in experts as well regarding this but as it's now picked up here, please ignore that post.)

Hi all can anyone point me in the right direction where i can find the diagram for making a constant current regulator that is on this site. I have made one of these before and used it for several years with success. I now want to make one for my friend. Also i can't get onto the store site it is saying forbidden. I have also purchased a silvertron  last year and want another one for a family member.Any help will be appreciated.

I'm preparing for producing the kephra's method.

1- I bought corn syrup yesterday, color is transparent, it has no yellow color, is that mean its light syrup that kephra using and is this the best form of syrup?

2- i need assistant about my silver wire shape and calculating surface area. The submerged area is about 13cm, width is 2,95mm on top and 2,65mm on the bottom (i've used it before for my ex formula) avarage diameter is 2,8mm, i thought i need do the calculation based on the average 2,8mm diameter, is that ok? It's also weighs 11,54 grams.

3- My silver wire has rectangle shaped not rounded, Do i have to multiply the surface area by four? For ex. 13cmx0,28cm=3,64cm² this is surface area for the one side of the wire, it has 4 sides, do i have to multiply by four?

4- I can set the electrode spacing minimum 43mm because of my electrode fixture. Based on my electrode sizes, what is the best electrode voltage for this? I know from article nr. 3, for wider electrode spacing, you need higher voltage. I know 10-12 volts good for 37mm spacing.

5- @cfnisbet says on blog "1 ma per square centimetre of submerged anode area for the suggested current when processing DW hot.
10 ma per square inch of submerged anode area when processing DW hot.
2 or 3 ma per sq inch of anode area when processing cold."

I will do the process cold, after it finished will heat it to the 60°c than will add the RA. In this case what is the current i need with my square wire?

I would suggest 3-5 mA for all wires or similar-sized anodes.

Don't bother trying to calculate a current.  Here is the only thing that matters.
If you see brown smoke like clouds coming off the positive electrode, your current is too high, reduce it until you don't notice the smoke.  Use as large of an anode as possible unless you have a magnetic stirrer.

Karo comes in three varieties, "Light", "Dark", and "Lite".  Do not use "Lite".

Electrode voltage should be 3.5 + .175*mm where mm = electrode spacing in millimeters.
So for 43mm spacing, minimum voltage should be 11 volts.

@kephra to learn and clarify the exact amounts instead of aprroximate drop amounts of electrolyte solution, I measure the weight of the electrolyte drops for full of tea spoon as you say. I count 35 drops from my dropper bottle to fill the tea spoon. Divided this by five = 7 drops for 1 liter. Also total amount of 35 drops, weighs 1.33 grams.

I buy washing soda from grocery store, measure the weight of the soda 12.40grams in 100ml beker and i added require amount of DW to fill it to the 100ml level.   

You all can see drop count weight in this video: https://www.youtube.com/watch?v=PwProqwnu6E

Well there is something wrong with your measurement.  For a 1 liter batch, you should use 1 ml of 1 molar sodium carbonate.  1 ml weighs about 1 gram.  Your teaspoon showed a weight of 1.3 grams when full.

A standard teaspoon holds 5 ml, so should weigh 5 grams of water.

@kephra, yes you're right. I think my teaspoon is smaller one. I'm not living in the us. I measured it again. 1ml of DW weighs exactly 1.00 grams, and 1ml of Electrolyte weighs exact 1.10 grams. And with my dropper bottle 25 drops weighs 1.10 grams. So if i put 25 drops electrolyte from my dropper bottle to the 1 liter batch, i am putting 1ml of electrolyte.

Does the Sodium Chloride has to be chemically pure and food grade? Or just any washing soda without extra detergent additives would be fine?

I think you are cnfusing sodium carbonate with sodium chloride.
Sodium chloride has no place in making colloidal silver.
Sodium carbonate should have no extra ingredients.
You can make sodium carbonate from baking soda (sodium bicarbonate) by baking it, but only use 1.6 10.6 grams of the powder to make 100ml of electroyte.

Sorry, i mean sodium carbonate. I did misspelling.

OOPS,  I said 1.6 grams which should have been 10.6 grams.
