This video took WAY longer to make than i thought it would. I was hoping to release it on Saturday but so many tiny little problems delayed it until now. Hope you all like it.
Brilliant idea and solid build. A simple solution for a complex problem. One remark: I strongly recommend black and red wire for the DC input and output. As an electronics engineer, I often enough supplied the wrong polarity. Of course, my own stupidity, but colors help to prevent it. And other note: You can desolder the potentiometers from the DC/DC regulator and mount bigger, nicer ones lets say in a box, wire it up and put it on your table. off course, the pcb potentiometers have their safety feature of "not accidentally changing", but at the same time, readjusting them during an experiment can be hazard as the screw driver might short out the circuit or accidentally turning the wrong direction. (but short circuiting the circuit could also be prevented by simply using a plastic blade/trimmer instead of a metal screw driver),
sarowie Very true, and very good ideas. I'm planning on making an "advanced Electrolysis box" in a few months or so that also allows capturing of useful gases or even feeding in reactive gasses (which is awesome for fuel cell experiments). I'll see if i remember to incorporate your suggestions :)
NurdRage the potentiometers on the regulatory are 10 turn so if using external pots either use a bigger 10 turn one or two different values for fine and coarse adjustments.
+NurdRage Wait, can't the current one also capture useful gases? I mean, I could see myself generating say, hydrogen/oxygen in one and piping it over to a blowtorch or experiment. I guess you mean SEPARATE useful gases by electrode, which could indeed be very useful.
NurdRage is obviously Walter White, he has to hide his identity with a voice scrambler, and he (surprise surprise) makes an electrolysis box, just like the one Walter White made. Coincidence? I think not.
SUGGESTION: what you created is a perfect calm chamber where gases will stratify. Therefore your aspiration line should be put at the extreme top of the tank to vent idrogen (very common byproduct of every electrolysis) AND at the extreme bottom of the tank to vent clorine and similiar heavier alogens. You are a chemist, so I will not waste your time explaining the huge difference between what thermodynamics says about mixing gases and what in reality you will get. ciao
GiGaHarrySfotter The box is not perfectly calm. The lid leaks inward as much as the pump can pump it out. The turbulent entry of air mixes the gasses quite a bit. Nonetheless, as is said at the end of the video the box is returned to the fume hood and opened there to vent lingering gases before the experiment is observed.
Excellent video as usual. The simple way you convey your ideas illustrates a firm understanding of principles. I plan on creating one of these, but simply as a mini, self-contained fume hood.
Great idea, NurdRage! The PVC tubing could be led into a 'scrubber'. For example, if an electrolysis procedure produces bromine or chlorine, the tube could be led into sodium thiosulphate. For nitrogen dioxide, the scrubber would consist of sodium/potassium carbonate or hydroxide.
You could also add a digital tier module and alarm and a manual override to keep the pump running after electrolysis has finished. Also some tape on the cables so you dont get caught on them and accidentally pull them off etc. Cool idea, think i might make one!
Have you ever considered running a bead of say silicone around your tub? If you ran it in the mating surface and let it setup and cure, you could make a gasket of sorts to seal your box even better. It's a trick used in the automotive arena for making quick and cheap custom gaskets.
Do you really need MLA documentation? Do you at some point not do this so you feel you can point it out elsewhere? Do we know our proverbs? Dont worry abour the speck in their eye but rather the plank in thine own eye. Ok. You good?
Nicely done. I made a "fume hood" version of this a few months ago, using a larger storage tote and a 12v fan. Connected the fan to a surplus vacuum cleaner hose (likely vinyl) and then routed it into the venting from the clothes dryer where it exits the house. No blowback through the hose from the dryer, though the fan is perhaps a little anemic, so may switch to a cheap bathroom fan if my attempt at raising the voltage burns out the little guy. What is the cfm of the pump you are using?
You should check out the B3603 or the B3606 DC-DC converter for a digitally controlled converter. They are a bit more expensive than the potentiometer controlled converters but at around 12$ I find them to be a HUGE improvement if you plan to change the voltage or current limit a lot.
+NurdRage you could have soldered bigger pots in the converter.also,would love to see you do electronics videos.you seem smart enough to understand it and it's a nice hobby
KuaisArts Thanks for letting me know you use them! :) Whenever i make them i keep wondering if people even bother to use them. Knowing that some people do motivates me to keep subtitling :)
NurdRage Just recently stumbling into a interest in this kind of stuff, so some of the terms and concepts are new to me. Mostly been using subtitles when figuring out some of your terminology (with no past context to work with, sometimes it can be hard to figure out the right spelling or even the right word for things, yay learning). So thank you for those!
Thanks Dr. N. Butyl Lithium. I get a real kick out of your pseudonym. A lot of thought has gone into your set up. Appreciate the links for parts. Very helpful. Again many thanks for sharing your talent. Carl
I used electrolysis to make various chemicals for fun before, but the various fumes that can result are not something you want in air you're planning on breathing. If I do anything involving electrolysis in the future, I'm probably going to build a box like this, since I'm lacking anything resembling a lab.
i would like to know if there is a small scale way to get ti from titanium tetrachloride or any of the transitions easily achieved in a home lab. i know my question would be better received if i were part of the funding community but i haven't worked in a few years due to an autoimmune condition so im taking a shot.
Fod Woggler I would not recommend putting lithium metal in an aqueous solution for obvious safety reasons, lithium reacting violently with water. I believe elemental magnesium is made in the industry (at least in the US) by electrolysis of molten magnesium chloride (that you would have to prepare from the Epsom salt) under argon atmosphere (magnesium itself being reactive to moisture in the air, you need an inert atmosphere). You get magnesium metal at the cathode. To make things worse, magnesium chloride has a high melting point. Not really a thing that you can do in your garage easily I guess!
Fod Woggler there's not much info on google but you can separate elemental copper(very fine particles) from copper sulfate by adding ascorbic acid (vitamin C), it might work with magnesium too.
Fod Woggler generally the more reactive something is the harder it is for someone to obtain, homemade at least. Magnesium is fairly cheap and you can sometimes find large amounts of shavings for very little.
I often melt aluminium and have an installation able to produce the required temperature, I would like to know what kind of precautions I have to use to separate Na and Cl. First of, what kind of electrodes is the most appropriate? I imagine I would need to use iron, but then, what voltage would I need to make it viable? Also, with the air coming from the bottom of said installation to burn the fuel, would be there sufficient oxygen to instantly oxidize the molten magnesium?
Looking good though I can't help but notice that you didn't mention anything about sealing up the holes for the hose barb and the electrical connections over sight or am I just overly paranoid about how tightly sealed something needs to be?
HI, I have learned a lot from your videos, thank you for your time in keep doing it! Now, a silly question. Is it your voice that low, or do you use some software to conceal identity? Thanks!
I'm starting to believe he's not actually hiding his voice at all. Now that he's had a better microphone for quite some time, it doesn't sound so processed as someone who actually lowered their voice.
Can you make a thing that will have a very high voltage but very low current that way we could can dissolve the anode fast, to increase the speed of making iron oxide while having a low enough current that it will work correctly.
Could there be fumes which destroy the pump mechanism? If so, it might be better to have the pump deliver fresh air into the container from one side and have the outlet tube on the other. Just make sure the lid is sealed.
Markus Birth I think he said the pump cost $6... if it dies in the process, toss it and replace it. I'd rather have a negative pressure on the box, than try to seal a positive pressure - much easier.
+Markus Birth (mbirth) the pump motor, and pump action...are separate meaning theres a barrier between the two,,,,lots of pupms are made this way for the reason they may pump corrosive materials.
How about _selling_ these to us scientists who don't necessarily want to have to build it? You can overprice it just a little bit to make the purchase account for shipping and a little profit for your other content.
Just a thought, If the box can handle NO2 you could connect the output of the pump to a bubbler filled with NaHCO3 and generate some NaO3 while scrubbing the air. Also, where did you get your fume hood from?
I have a question about water electrolysis. I want to generate more or less pure oxygen using electrolysis. Someone told me it is impossible to avoid contaminating the oxygen with some hydrogen, which will then accumulate in my tank (150 gallon at 110 psi) and probably explode at some point. (Annoying, but the tank will be far away from anyone) Other question is, what kind of efficiency can I expect out of it ? I'm going to run it continuously with my tap water and a 5 gallon salt supply which will keep the solution saturated. I don't have access to fancy polymer membranes but I have stainless steel, plastic and reasonable fabrication capabilities. How many liters of oxygen per kWh can I hope to achieve ? How many liters of oxygen per hour can I produce with a 20 gallon electrolyser ? What kind of oxygen purity can I expect ? What is the most efficient design electrolyser that can be built out of materials from a big hardware store ? How much water will the oxygen gas contain if I run the electrolyser at 20C ? I need this oxygen for feeding an oxy-acetylene torch. It doesn't have to be pure but it can't be combustible prior to mixing with acetylene, also water content would be annoying as it will eventually corrode my system.
Is a voltage regulator necessary? If I remember correctly back when I was younger I used a car battery charger and could change the voltage by changing the distance between the electrodes.
I want to make an electrolysis box and use it for making potassium chlorate but I don't understand how to power the whole process, I haven't got very much knowledge on these things and so am rather dumbfounded. If anyone has any suggestions pls answer
Hi Nurdrage! Could you do a video on an electrolytic cell for generating ClO4- ? I'm too much of a wimp to try the molten chlorate disproportionation method!
Hi, could I request a (somewhat newbie) video on copper plating? I have a project that requires it but I keep getting a blackened mess, which is odd and confusing as I've done silver and gold plating somewhat successfully in the past (with smaller quantities). I would rather have something that doesn't involve sulfuric acid as I've wasted all of mine on other things. Any tips? Thanks :) Also I love this video. I will be making one.
Hi Nurdrage, could you please provide the (ebay) links for the parts you used? I love your videos, thank you so much for taking the time and effort you put into this.
If I were to use an electrolysis box such as this, but I wanted to conduct a electrolytic reaction that produced gas and keep the gas produced by routing the diaphragm pump output to another container, how would you go about this without having said container burst/leak from the pressure exerted by the gas going inside?
nospacesWFT That critically depends on the gas. Some gases can be absorbed into solutions. Some can be liquefied and some you have to pressurize into a strong container made of a compatible material. I don't recommend this particular design for using the gas. It's far to dilute with air mixed in. I'm working on a more advanced electrolysis box that's specially designed to capture useful gases.
nospacesWFT Have a look at paintball HPA tanks, they are fairly cheap and are designed to handle high pressures, and you can easily integrate them using an ASA from a paintball marker. This is obviously assuming your gas doesn't attack the macroline or the tank itself.
Hey I was wondering if you have any videos on how to make colloidal silver or the difference between colloidal silver and ionic colloidal silver? Nobody really has a legit video up on it. I know that there's many uses for it, it would be pretty useful credible people including myself.
so i went ahead and bought one of those DC/DC converters, and it works fine, except the amperage maxes out at 5 amps and the voltage doesn't go below 0.7... any way around it? actually, is there any way to lower the voltage to below 0.7... not the amperage.. the back of the module heated up quite a lot while i was testing its limits, so im guessing 5 amps is the max for a reason.
Unknown Actually, it's listed right on the seller page and in the title of the item that it's a 5 amp converter. It also lists the output range as being between 0.8v - 30v. There is no reason to be surprised, it sounds like it's working exactly how it's supposed to. What did you think you were buying?
Will you ever use the platinum based chemical (the one you made from dissolving Pt in royal water) in any videos!? I'm dying to see those reactions!!!!
SpitefulAZ Eventually... I don't know when. For one, that stuff is so expensive, i need to *perfectly* plan any experiment with it because i only get one shot. Mess it up and i'm flushing money. So it's taking an incredibly long time just to get started.
Are there any reasonable generic filters for gasses? Activated carbon, with a base and acid prewash to neutralize gasses (picking neutralizing solutions to avoid anything particularly nasty)?
Robert Szasz If you had the time, money and space, then leading the gases through an acidic absorption column column, followed by a strongly basic absorption column and finally through a flame burner (to destroy flammable gases that are absorbed by neither) would pretty much handle any gas you could throw at it. The major drawback though is maintenance and cost. It's a complicated system with pumps, fluids and a host of other components. Activated carbon does work, but it will be quickly overwhelmed by the sheer volume of gases produced in a few preparatory scale electrolysis experiments.
NurdRage I guess dilution is the solution (vent outside). Though since I'm just doing plating and cleanup of copper chloride solutions from etching I only really have a bit of chlorine to deal with and some lye or baking soda in solution with an indicator is all I need. Oh and a bit of added H2O2 makes for a much nicer etch with copper chloride.
i have a few question about the boxes you use. You said you use pe（polyethylene）boxes but they look a bit like pp boxes. Do pp boxes work too？ and if not can someone give me a link to good pe boxes because i looked all around the department stors in my city and they only got pp plastic boxes.
NurdRage! Do you know of any electrolysis reactions that yield gasses that would relatively quickly want to recombine to their liquid state quickly? Or are easy recombined to their liquid state through another simple reaction? I know Electrolysis of H2O yields H2 and O2. But those take too long to recombine to H2O for my needs. Thank you so much!
As much as i know about H20 , H2 and 02, after electrolysis , hydrogen will go up , because it's lighter than air and oxygen will be inside the electrolysis tube, because it's heavier than air, so you would need to hold, like a test tube above, but it wont be pure hydrogen, it would have some air in it, not sure how you obtain the oxygen, you could only do it when there is no water left
BK201MXP Define "relatively quickly". The hydrogen-oxygen you mentioned can be recombined with a spark, so not sure how quickly you are looking for. The bigger issue is that there aren't that many options for compounds made up of only gasses, that you could use electrolysis on that also easily combine with each other first. Maybe ammonia, unless you get into compounds containing fluorine, and no way I'd want to mess with something that reactive outside of a very well equipped lab.
Glebs Litvjaks Probably be easier to use HDPE nuts and bolts. Stainless isn't as resistant as you'd hope it would be, at least against acids, and especially if chlorine or HCL is involved.
How’s the pump going to be same output as electrochemical variation, he said -4 bolts now, so need lower for pump. How many pick ups for output does he have?

NurdRage oh and a second or third color pair to show input vs output is useful in regulated situations.
NurdRage the potentiometers on the regulatory are 10 turn so if using external pots either use a bigger 10 turn one or two different values for fine and coarse adjustments.
sarowie haha Yeah! when i saw the two red leads a cringed and recalled the times i burned things to hell because of that hahaha
+NurdRage Wait, can't the current one also capture useful gases? I mean, I could see myself generating say, hydrogen/oxygen in one and piping it over to a blowtorch or experiment. I guess you mean SEPARATE useful gases by electrode, which could indeed be very useful.
2 ideas, 1.Rubber gasket seal on lid and rubber "o" ring around hose barb. 2. A timer could be installed and wired to shut power off.
NurdRage is obviously Walter White, he has to hide his identity with a voice scrambler, and he (surprise surprise) makes an electrolysis box, just like the one Walter White made. Coincidence? I think not.
Quo Vadis he is cooking meth in the box
I don't understand a word of this but I still love every minute of it.
Very clever.... I've never thought of this....! Will have to do something like this sometime...
That means a chlorate cell video?? Hooray!! I'm waiting to build mine since 2008
did you build it yet?
SUGGESTION: what you created is a perfect calm chamber where gases will stratify. Therefore your aspiration line should be put at the extreme top of the tank to vent idrogen (very common byproduct of every electrolysis) AND at the extreme bottom of the tank to vent clorine and similiar heavier alogens. You are a chemist, so I will not waste your time explaining the huge difference between what thermodynamics says about mixing gases and what in reality you will get. ciao

Great idea, NurdRage! The PVC tubing could be led into a 'scrubber'. For example, if an electrolysis procedure produces bromine or chlorine, the tube could be led into sodium thiosulphate. For nitrogen dioxide, the scrubber would consist of sodium/potassium carbonate or hydroxide.
You could also add a digital tier module and alarm and a manual override to keep the pump running after electrolysis has finished. Also some tape on the cables so you dont get caught on them and accidentally pull them off etc. Cool idea, think i might make one!
WOW
Big work Nerd Rage.
Hug from Brazil man
Great video!
I can definitely see improvement in the quality of the videos, I guess the Patreon is working out. I'm very happy to see this!
Have you ever considered running a bead of say silicone around your tub? If you ran it in the mating surface and let it setup and cure, you could make a gasket of sorts to seal your box even better.
It's a trick used in the automotive arena for making quick and cheap custom gaskets.
your videos should be used as teaching material with proper credit given
Do you really need MLA documentation? Do you at some point not do this so you feel you can point it out elsewhere? Do we know our proverbs? Dont worry abour the speck in their eye but rather the plank in thine own eye. Ok. You good?
Nicely done. I made a "fume hood" version of this a few months ago, using a larger storage tote and a 12v fan. Connected the fan to a surplus vacuum cleaner hose (likely vinyl) and then routed it into the venting from the clothes dryer where it exits the house.
No blowback through the hose from the dryer, though the fan is perhaps a little anemic, so may switch to a cheap bathroom fan if my attempt at raising the voltage burns out the little guy.

You also need Ph & Temperature sensoring with acid auto adding if it goes too basic (PH control).
could use a pressure gage offset for negative pressure sealed lid and a one way air valve

Couldn't you capture the gases in a fitting solvent, like water?
Awesome video I'm going to donate
what do you use for an external power source?
I used electrolysis to make various chemicals for fun before, but the various fumes that can result are not something you want in air you're planning on breathing. If I do anything involving electrolysis in the future, I'm probably going to build a box like this, since I'm lacking anything resembling a lab.
Glebs Litvjaks i think you need to rewatch the video, nurdrage says he uses the box to vent the gases outside so the gases don't built up.
i would like to know if there is a small scale way to get ti from titanium tetrachloride
or any of the transitions easily achieved in a home lab.
i know my question would be better received if i were part of the funding community but i haven't worked in a few years due to an autoimmune condition so im taking a shot.
Next project, build a XRF Analyzer, you would then see your hose barb has lead in it
That looks useful. Perhaps for other things as well, I believe.

So how can you catch the hydrogen purify it and pressurize it??

Could a MMO (Mixed Metal Oxide) electrode be used for Electro-Bromine Sulfuric Acid Synthesis?
Will you ever use the platinum based chemical (the one you made from dissolving Pt in royal water) in any videos!? I'm dying to see those reactions!!!!
SpitefulAZ Eventually... I don't know when. For one, that stuff is so expensive, i need to *perfectly* plan any experiment with it because i only get one shot. Mess it up and i'm flushing money. So it's taking an incredibly long time just to get started.
SpitefulAZ Our lab had to pay 200$ for 3 grams of Platinium based compound for Suzuki Coupling. Ouch!
Are there any reasonable generic filters for gasses? Activated carbon, with a base and acid prewash to neutralize gasses (picking neutralizing solutions to avoid anything particularly nasty)?
Robert Szasz If you had the time, money and space, then leading the gases through an acidic absorption column column, followed by a strongly basic absorption column and finally through a flame burner (to destroy flammable gases that are absorbed by neither) would pretty much handle any gas you could throw at it.
The major drawback though is maintenance and cost. It's a complicated system with pumps, fluids and a host of other components.
Activated carbon does work, but it will be quickly overwhelmed by the sheer volume of gases produced in a few preparatory scale electrolysis experiments.
NurdRage I guess dilution is the solution (vent outside). Though since I'm just doing plating and cleanup of copper chloride solutions from etching I only really have a bit of chlorine to deal with and some lye or baking soda in solution with an indicator is all I need.
Oh and a bit of added H2O2 makes for a much nicer etch with copper chloride.
where is the custom chlorate cell videop ? i cant find it
How long does the pump last? Of 24/7 use
Will electrolysis work on cast aluminum?
Thanks
Is this really your voice or do you use a voice scrambler
Thank you, every time I watch his videos, I always want to ask but never do
I wonder this too. Hope he replies to this question himself.

Jas Tavares Nurdrage is a girl, but don't tell anyone ;)
No way! Hands are more masculine than that of a girls...
To be clear, it needs 14 volts and 100 Milli amps to run?
No, you only need something that has 1V of headroom.
Meaning if you want to output 14V, you ideally want at least a 15V power input.
i have a few question about the boxes you use. You said you use pe（polyethylene）boxes but they look a bit like pp boxes. Do pp boxes work too？ and if not can someone give me a link to good pe boxes because i looked all around the department stors in my city and they only got pp plastic boxes.
Yep, polypropylene (PP) works just as good. By all means use it if you have it.
NurdRage! Do you know of any electrolysis reactions that yield gasses that would relatively quickly want to recombine to their liquid state quickly? Or are easy recombined to their liquid state through another simple reaction?
I know Electrolysis of H2O yields H2 and O2. But those take too long to recombine to H2O for my needs.
Thank you so much!
As much as i know about H20 , H2 and 02, after electrolysis , hydrogen will go up , because it's lighter than air and oxygen will be inside the electrolysis tube, because it's heavier than air, so you would need to hold, like a test tube above, but it wont be pure hydrogen, it would have some air in it, not sure how you obtain the oxygen, you could only do it when there is no water left
BK201MXP Define "relatively quickly". The hydrogen-oxygen you mentioned can be recombined with a spark, so not sure how quickly you are looking for. The bigger issue is that there aren't that many options for compounds made up of only gasses, that you could use electrolysis on that also easily combine with each other first. Maybe ammonia, unless you get into compounds containing fluorine, and no way I'd want to mess with something that reactive outside of a very well equipped lab.
Saying good bye and now coming back...
99% of people like that missed the MONEY!
Ludwig Skiller Never said goodbye. And youtube pays jack shit. Stop making assumptions.
Having trouble locating a DC-DC converter that specifically says the current is controllable. Please post a link to the one you used.
loganv0410 Done! check the video description :)
NurdRage thank you!
What did you use as a power supply?
nice video but iI probably going to use 9v battery and don t buy expensive converters
is the mini-DC-DC converter needed?
can you use stainless instead of titanium?
xtamared Yes he said so in the video, however they will corrode faster.
xtamared it depends on the reaction(s) you are planning to do and how much hazel you consider it to replace screws and nuts every now and then.
Glebs Litvjaks Probably be easier to use HDPE nuts and bolts. Stainless isn't as resistant as you'd hope it would be, at least against acids, and especially if chlorine or HCL is involved.
why do you added a stirrer to th beaker if there is nothing to let it stirr(dont know the name for the machine :D)
It was from before when i made the solution by mixing copper sulfate and water. I didn't bother removing the stirrer
oh ok
Can you use this box for growing weed?
Where did you acquire your MMO?
+NurdRage can you make an chlorate cell video :)
Does electrolysis always produce toxic gasses?
Crowforge no
when will stuff explode
target box! :D
yes i work at target (if this is not a target box i apologize.)
No targets in Canada anymore...
Pearl Ang i also work at target and that didn't look like any room essentials iv seen XD
Positive: Red
Negative: Red
What were you using as a power supply?
Probably something like a 12V battery charger.
How’s the pump going to be same output as electrochemical variation, he said -4 bolts now, so need lower for pump. How many pick ups for output does he have?
Ok so this is a strange remark. But your hands make u look really young how old are u
what is name of that pump?
Im not very good at english
Blu Deat Diaphragm pump :)
thanks
Do you take donations via paypal? NurdRage
Are you ever going to do a face reveal
I've never thought of it until now but are you a girl or a boy?
Take a Wild guess.
Is this a women's hands?
I have no idea what's going on
'just vent it through the window....' you monster, at least put a few $ charcoal filter at the end.
Science bitch!
