Almost done with part 2 of the long format copper acetate deep dive. As expected: although the stoichiometry leads us to believe there would be almost no solid copper left behind, quite a bit was. My hypothesis was hinted in the first video. I'll explain in the upcoming. #chemistry #copper…

No batteries? Just jerry-rig the scale. Long format video coming soon :) #chemistry #engineering #electronics #lab #antisyndicate

ацетат цинка | pt 2. I exposed the zinc core of the pennies and the acetic acid attacked the zinc: Zn + 2CH₃COOH → Zn(CH₃COO)₂ + H₂↑ Zinc is sufficiently reactive to displace hydrogen from the acetic acid and because I left the pennies in the solution, my hypothesis: I still had copper metal…

I repeat: [ A 3D printer is a robot. ] pt. 5 My b, I was doing Vulkan and AI things. Anyway, I got two halves of a cartesian bedslinger 3D printer. One provides us with one dimension of motion. The other with two dimensions of motion. Both halves give us a payload area and both halves require some…

ацетат цинка synthesis | Zn + 2 CH₃COOH → Zn(CH₃COO)₂ + H₂ ~ 23 hours into reaction. It is also a single-displacement reaction, redox reaction, and gas-evolution reaction because zinc displaces hydrogen from acetic acid and releases H₂. Zinc was sourced from American pennies. I used my file to…

ацетат цинка | pt 1. Anhydrous form: Zn(CH₃COO)₂ Dihydrate form: Zn(CH₃COO)₂·2H₂O It is usually a white crystalline solid, not colorful like copper acetate so it's less visually dramatic. It is a chemical precursor, a lab reagent, and a route toward zinc oxide materials. if you use zinc metal…

ацетат алюминия | I was wrong. I'm rather certain now that I actually did produce ацетат алюминия. Reynolds Wrap aluminum foil is approximately 98.5% алюминия. At that percentage, or near it, I don't believe the presence of iron had that much of an effect on the reaction. Rather than rust or iron…

Проверяю экстракт на горение. этанол: 2 min 31 sec этанол + мандариновая цедра: 2 min 37 sec 🤔 The burn time didn't change much, but the interesting part seems to be the soaked mandarin peels themselves. They slow the burning locally while converting into what looks like charcoal. So the added…

motor de polo sombreado | pt. 1 My brain: "🤔 This one's cool cause it has no brushes and no permanent magnets, only electromagnetism doing goblin work." This is a single-phase AC induction motor. Unlike the universal motor in one of my previous videos, this one does not use brushes or a…

Immersion Vibrator V1 | pt. 4 Ensamblaje complaciente. Senti que los tornillos iban a complicar demasiado la estructura interna de la carcasa del motor, asi que modifique el diseno. Esto hace que sea mas barato de fabricar y mas facil de ensamblar. Con eso en mente, ahora estoy trabajando en el…

Immersion Vibrator V1 | pt. 3 (•̀o•́)ง Here's me testing my custom eccentric weight. The experiment was not only successful, it accidentally proved that with this DC motor and weight: I can even build a vibration table. My design challenge here is to build a handheld unit though, so I'll have to…

Immersion Vibrator V1 | pt. 2 I had to design an eccentric weight for my DC motor. First things first: "I need something heavy and small." So I grabbed my bag of nylon lock nuts: "these are kinda heavy 🤔." I pulled out the calipers, measured the available motor real estate along with the hex nut…

этанол + мандариновая цедра | 22-23 days later. The solution / extract is a deep, intense orange. The seal on the container I was using was beginning to give, evident from the slight smell of этанол and мандариновая surrounding the storage location. This isn't safe to I'm stopping the extraction…

Ацетатные реакции | Reaction Updates Ацетат меди reaction was successful. Кристаллы очень красивые, catching the light and revealing various shades of blue. Ацетат меди is a common precursor to synthesizing other materials. It can also act as an oxidizing agent, catalyst, or reagent in some…

High Voltage Трансформатор | pt 3. High Current configuration working :) So what was the issue? I damaged a small component, what I think was a thermal fuse hooked up to the primary coil. Anyway, I gutted it and bypassed the open connection by soldering the primary closed. Don't do it, это глупая…

High Voltage Трансформатор | pt 2. Well... I modified the трансформатор. Because of the physics behind transformers, you can configure them to output high voltage or high current. It all depends on how you set up your secondary coil: wire thickness and the number of turns. Removing the secondary…

High Voltage Трансформатор | pt 1. Got it wired up, but no big arcs. I have 2 options: I can set up some diodes and rectify the output. OR I can modify the transformer. I'm leaning toward option 1, as there's still a lot of experiments I can run in the current configuration while explaining…

I repeat: [ A 3D printer is a robot. ] pt. 4 Now I've modified my control logic so that there's control over speed and direction via a potentiometer. A great precursor to full on control via physical control panel, and soon, a digital one as well. Now I have speed, direction, and emergency stop…

I repeat: [ A 3D printer is a robot. ] pt. 3 And since engineering is just like programming, I'm now removing all of the original assumptions. So I'm removing the print head and hotbed. Not because I won't ever use them again, but because they are assumptions that have defined the configuration of…

I repeat: [ A 3D printer is a robot. ] pt. 2 Engineering is just like programming. Can you see this single dimension/axis as a function? Or even a class? But instead of software logic, it's a mechanical assembly. The programming side of robotics, even if you are as low as literal assembly logic…

I repeat: [ A 3D printer is a robot. ] pt. 1 So here is one dimension. One axis of motion. The modern consumer is amazed by three dimensions, yet too distracted to understand the value of single one. So here I place a limit switch on it. Can you see it now? What is robotics? A loaded question. A…

Immersion Vibrator V1 | pt. 1 Working on the motor mount. IDK what this is called... a split clamp? a split collar? 🤔 I'll figure it out and circle back. For now, the measurements are solved. Tomorrow, I'll focus on the weight and intensifying vibration. Then I'll focus on the electronics. Then…

One-week natural weathering test | Day 0 How will the cementitious composite handle sun, heat cycling, humidity, and general weathering? 🤔 I'll reveal and explain my hypothesis in 7 days from now. For now, let's talk PLA. Polylactic Acid (PLA) begins to soften and deform at roughly 60° C / 140°F…

Small DC motor... Immersion Vibrator? 🤔 When pouring the Cement All into the molds, the main issue I had was: if I didn't persistently oscillate/bang the mold and funnel against the ground, I got no cement flow. So now I will engineer a concrete vibrator? internal vibrator? Whatever it is called…

3D printing tolerance | The filament hog This is one of the most annoyingly understated and underestimated concepts in 3D printing. The dimensions of your design and the dimensions of your printed part will almost never be perfectly 1:1. There is always some amount of error. This is the biggest…

AC to DC Converter | One of my favorite pieces of equipment If it has a battery in it... and that battery no longer functions... assume I've attached it to an AC to DC convertor 😂 This one can output up to 10A, compared to my lab bench supply that can output 5A at most. This is one of my favorite…

Числовое программное управление (ЧПУ) | Hacking my old Prusa pt. 1 I'm going to swap out the old Einsy RAMBo for an Arduino GIGA R1. It's a good choice and a bad choice. Bad because there is no handholding: I even have to wire up my own motor drivers. I'm okay with this. The hardest decision to…

plastic shell + cementitious core composite material test #1 initial test: I used Polylactic acid (PLA) + CementAll. CementAll because I couldn't find a bag of Portland cement, and also it has non-shrink properties. 1. I figured it would be a challenge to get the CementAll into the PLA shell, but…

шестерни ч. 002 | gears pt. 002 The noise test. Pretty much: If a gear is making noticeably more noise than the others... it's probably the one most out of spec. шестерня A and шестерня B meshed really well. шестерня C made the most noise to my ears. All in all though, all three gears successfully…

шестерни ч. 001 | gears pt. 001 So I measured the gear on the motor assembly and noted the number of teeth. I used those measurements to calculate a range of test cases. The only difference between the test prints is the module values. You'll notice each gear is slightly larger than the last. I…
