Water and sewage - House reconstruction #3
In this episode of thickening I present some progress.
This is bit more dry one (lol), because I am dealing less and less with original construction, and I don't have much time to go back and include all the stupid shit I've had to deal with like 60mm thick layer of plaster on some walls, or walls that are 50mm out of level so I had to add section of drywall at ridiculous angle, anchor it in place and continue finishing from there...
But also soldering pipes on roof insulated with hey is pretty good adrenaline sport, I must say...
Anyway, it is good system, I just could have used bit bigger pressurized tank or how is that thing called.
I think this will be last video in the series, I am plann...

Renovation continues - Electrical inspection (mainly)
Просмотров 1868 месяцев назад
Electrical installation mostly done, at least enough for inspector to inspect... Question is will it pass? The answer may probably surprise you as much as it did me :D I will be doing water analysis very soon and then I will do bunch of masonry, which will be boring af. But I will need to construct water and waste infrastructure inbetween so will try to document that.

Watch how optimism about moving in quickly fades, as schemes to devil summoning become apparent. Glad nobody energized this home, or who knows what would happen with this world. Now after editing this video it all came together - that switch in bathroom was used to re-activate the timer after long purging sessions, lol. As I continued with renovation, I thought I have seen everything. But after...

Eeh EPILEPSY WARNING: very flashing images Also shitpost warning. Unfortunately the camera is not fast enough to capture exactly what I would see, but it's good enough... I do have more powerful flashligh, but it's powered by flyback transformer and it takes a while to discharge 60V capacitor, so don't think it would work as well.

Have a look at what not to do when you want to make this molecule. I want to make it in larger scale though, next time I will be hopefully more successful. This reaction was my 5th attempt and I thought I've got this down, but nah. Now I know more. I'm gona melt you down!

There are much worse ignition sources.
Use nail varnish also to insulate the windings its like a much less viscous version of expoxy resin
Hi. I wonder what’s an advantage of using optocouplers? It seems all parts can share a same gnd, and gate drivers are 3v3 compatible
They allow for sloppy design. I did not have scope back then, and during development I burned bunch of mosfets. This caused arduino to die as well. So I just protected myself this way which allowed me to debug issues by trial and error.
@@IlusysSystems Aha! That was very smart. Thank you for the info.
Thank you for sharing your knowledge, I had a question about the combination of expanded polystyrene with gasoline, how and with what material or materials can the glue obtained from this combination be diluted?
??
where is part 1? You also mentioned a modification where a wire was soldered to the transformer. (not in the video). Which one, and for what purpose? If you can clarify that it would he greatly appreciated. Thank you for the suggestion in video 3,although it was mesmerizing cadmium will not be used.
awesome...specially the use of cadmium as an electrode . Very good instructional video. Thank you. Enjoyed it s lot.
Probably better to use non toxic metal for this. I have used Cd, because the geometry was about right for me, since the transformer had super low power.
English mate....english would help.
ahoj, dve otázky na teba mám. 1. odkiaľ si kúpil ten prikvapkávací lievik, 2. čo za piesok si použil/odkiaľ ho máš? Ďakujem
Ak myslis to davkovanie na HCl tak to je vlastna vyroba. Na SK neviem kde by som kupil, dnes sa da kupovat aj z ciny... v CZ kupujem z P-Lab, funchem alebo Verkon. Jedina vec je, ze su "kurva drahe", preto som to vyrabal (a minul este viac penazi :D) Piesok je z unihobby klasicky kremicity piesok. Napr na filtraciu do bazenov.
you distryied the coil with them screws .
and the hold with copper
Kitchen cutlery has 18% of Cr. It is scary to think about chinese stainless, because it rusts on the air. does not even need Cl.
It Is fast
Are the coils delta or strar?
When i added HCl to yellow solution of sodium chromate, instead of dichromate i got colorless solution...
Still, an instructive clip. I've done something similar using ferric chloride as my chlorine source. I too am careful with such reactions. A very famous rx about getting FeCl3 to about 70 C or so to etch copper clad circuit boards. Works pretty good with other stuff too. A lot of sitting around watching your thermometer and picking your teeth, so to speak. Well done.
Do you have the plans for it available?
Here is one. Aluminum electrode, water and AC
I first subscribed for your chemistry... amazing what else you have showed us as the years go by! :) Thank you for adding the term "shit manifold" to my vocabulary. 4:15 you need a good, strong seal on sewerage pipes! ... ... ... BUT! ...
Well, so many things to do, but so little time... I want to do another part of "Will it polymerize?" series, but I really want to have kitchen line. Fuck the cabinets though. Srsly :) That said, I need to setup the lab... I need bunch of cabinets there.
never heard about propane being used as solvent. such a wonderful video

From uk southwales brilliant video and cheers very glad
so what is size of the particle and morphology ??
Crystals, depending on concentration up to 5mm long. Cu crystals are nice...
Well, kinda unexpected quick update (23.3.2024): I forgot to mention in the video, the main reason why I went to neurologist - I've got an exploding head syndrome (LOL, but srsly look it up). Pretty harmless stuff apparently, but frightening as hell. Anyway, looking at some more literature, I found thing called "Sleep inertia" which I called paralysis. Could me more issues combined still... But the symptoms match quite well, and I can imagine severe cases actually causing severe issues when waking up. The sleep inertia is supposed to be caused by adenosine buildup, so that should be testable at least. In conclusion, it seems, that I am seriously fucked. Like having that much disorders in one particular bio/mental function would suggest to me, that something must be obviously wrong. But, I went to MRI, and mechanically, all seems to be OK. There is one thing that comes to my mind: When I was young, I did bite a wire that was live (240V). I lost consciousness and woke up screaming, which would suggest to me, that my heart did restart. this felt, like I was shot in the head (whatever that feels like, I would say it has to be pretty close). But on the other hand, I am pretty sure I had issues before that happened... Final note is that I will have to stop valproate experiment for next 6ish months. This is because you can't fly while using it. Was trying to get exception due to low dosage, but nope :/ I may try to check if valerian root extract contains any valproate (which I was allowed to use). Also the blood sugar test. But mainly will see the effect of stopping valproate usage. Update #2 (24.4.2024): I was busy moving to new location, so I had to prolong normal sleep cycle as much as possible. The date from this period clearly shows, that the paralysis intensity got much worse after I stopped using VPA, but question remains, whether this would happen anyway... In any case, this should be replicable. As paralysis intensity increased I have noticed, that my speech was getting more and more slurred after waking up to the point, that I almost wasn't able to speak. As I have technically completed moving essential stuff, I have stopped using alarm clock so resumed natural sleep cycle. Don't have much data still, but speech seems to be much less impaired after waking up now. This can be another "objective" metric that can be tracked. Similar to the speech slurring, I have experienced increasing eye redness. For now these seem to be highly correlated also subject to more research. This is very weird, but I feel like this amount of clues should get us somewhere.
Hello merci pour votre présentation, par contre je n'ai pas retrouvé la référence de vos leds
Remember kids , just because you know basic chemistry doesn't mean you can't completely retarded.
how to transfer chromium finish from cutlery to other objects?
Don't think that is possible.
How much voltage is applied?
Can we sell it?????
hmm zajímavé :D
If you bake a dense mixture, it will break due to repeated septation. Is there any way to secure this?
Would love an update video on this :) If you have time
How to rewind the motor it so simple
For those who want to make it: 1. You need a kiln heated to 800-850 C (you have to play with temperature 2. You need a mould (iron or stainless, quarz pipe pease wolud wirk, but never tried 3. Glass shall be ground on a ball mill and seived to size, depending on the porousity you want to get. 4. Put the frit to the mould and compact it (with beaker bottom or something. 5. Put the mould with the fritt to the heated oven for 5-7 minutes, but you have to play with time a lot to get good result. 6. Take mould out and cool on the table, remove glass when it is still hot. You may use some talc to make tge mold less sticky to glass
How's your experiment going ?
Actually it seems, that it is going well. So far I am testing sodium valproate, and it would be biiiiig coincidence, if I got 51 day streak of normal circadian cycle. However, in data previously recorded, there is such streak ,at about same time of the year, which may or may not be caused by using extract of valerian root, that I have prepared in certain way and did not just reproduce the extract later on... So I need bit more data to report on progress. Plan is to have data for 90 days of this particular experiment. Data for full year would be even better, but that would be fine as its own update.
Just made video if you are curious still ruclips.net/video/fMXLb21ehoA/видео.html
@@IlusysSystemsdude thanks for letting me know , I am watching it right now . Personally I always feel like crap when i wake up in the morning this goes on till the night then I feel good and I feel sleepy always at 5-6pm . Excuse my english.
This reaction produces sodium aluminate but how did you got aluminum hydroxide?
I have used 6g of NaOH to dissolve a lot of aluminium. It just can't be only sodium aluminate. How it works? I am not completely sure. My theory is, that Al is attacked by sodium ion of NaAlO2 and then it reacts with water. That is very testable theory, but didn't test it myself.
and also decrease the temperature 0 c°C is good but -20 °C is better
Can you make a video to make magnesium powder using magnesium chloride??
i have two suggestion: 1 use an aquarium porous stone immersed in te solution to increase de surface area between gas and liquid phases. 2 ad Thiourea to the solution , will help to reduce over oxidation and to convert byproduct in to haldehyde.
the only gas that can weld steel is acetylene....
Cool. I wonder if it can be used to make gems with like the alumina made from crushed corundum. Also, to get rid of the sodium salt you can wash your ceramic with water. Mix it with water, let it settle, pour off the top water and repeat until it isn't salty. Then dry the ceramic.
im just making it by electrolisis of a dissolution of distilled water and sodium chloride :-/ (metal negative carbon positive) (ps: i also used this method to make copper oxide)
Do you have a procedure to extract resin

Thanks for a follow-up video!
Perfact!
Parabéns pelo trabalho de qualidade!
This isn't really helpful, but even though the vapor pressure of benzaldehyde is low, the amount of gas you were running through it for that amount of time was probably enough to evaporate most of it as quickly as you were making it. I've had this problem when chlorinating hydrocarbons where the huge amount of HCl produced is enough to carry away most of the product. For me and for what I was doing, a dry ice gas trap worked. That probably wouldn't work very well for you though without at least a gas drier before the ozone generator or you'll get nothing but water ice.
It can build on the electric car
