moar decantation

decantation flask.
I've actually used the dichloromethane decantation process to extract caffeine from coffee.
seems decantation is your best bet.

so, whaat happened boss

your body will still have an impact with the things. it will act like a brick wall. the thing might work, but just by itself.
your body still has to stop.
newton's laws mate.

>>754111
EXACTLY.
I refuse to believe there is NO OTHER use for this other than for a really really fast RC car...

refining fuel's easy to get into. you should look into it. ethanol is a good, reliable source, which you can make at home

>>753931
that's so cool man. Hope i can live off the grid soon. are you planning on doing that?
also, do you know a ton about radio systems? if you do i have a couple of questions.. what nice anon

>>753918
still have them lying around? what did you use them for? just out of curiosity

>>753911
oh shit! this guy did EVERYTHING i wanted to do!
except for the sterling hahah
thank you for the vid man!! and the support ;)
also this guy used a drill to start the engine... is this a lot easier than by doing it by hand?

>>753910
several devices, a phone, a radio, and a flashlight. maybe not all at once. I could probably have a switch that depending on what state it is, goes through different loop with more or less resistence depending on the device I'm trying to charge. but yeah, all small devices.
also, if i'm going for power, should it always be revved up to the max to allow higher voltage? or should stable revs make it (a) less noisy (b) fuel last longer... while producing less power.
if max revs are better, do you think there's a way to make this a lot less noisy? maybe puting it in a box with sound insulation (with exhaust and intake outside)

hahah thanks for the advice
is a sterling engine more efficient than thermoelectric?? wuuut

>>753904
just trying some stuff, why the hell not?
the thermoelectric generators would be used to charge the glow plug after the piston has become hot. So, you charge it once solar, or what ever and then plug it in. start the engine, do whatever, and with the excess heat, recharge the glow plug so it doesn't have to be charged with solar next time.
>This engine spins too fast and has too low of power to make anything usable out of it.
nothing useful at all? well that sucks. how much power do you think i can take from there? in mAh, more or less
thanks for the reply anyway man

>>753892
thanks man!
about the thermoelectric generator... where is the best place to put it?? from memory i think the hottest place was the side of the blue part of the piston. I guess I could glue the thermoelectric generators to the side and connect them in series to generate an output that could easily charge the battery
awesome stuff man

>>753881
by solar power I mean making a solar charger specifically for the glow plug, no effort from my part required.
Another thing:
Glow plug gives off heat. (Physics 101 here we go) depending on the battery level, will it give more energy when fully charged than when charged at 50%? if so, why? I mean, it's still giving the same amount of electricity... isn't it? 1.2V at 1800 mAh...

>>753864
Thanks for shedding light on the subject, really helpful.
Well, the glowplug is 1.2V, 1800mAmps hour. To charge it up, could I use a crank motion thingy? (dynamo again).
It would also be cool to make the glow plug charge with the engine's energy output. I was thinking the following:
Either a solar charger, the crank thing, OR getting a thermoelectric generator and using the heat dissipated from the cylinder. It would have to charge fewer times with a crank motion.
What do you think?
>>753869
I might. I'll try something out and let you guys know.

>>753831
Thanks for the advice. I want to learn how engines work, and I thought this was a project that would be nice.
about the glow plug. could you expand a bit on why spark plugs would be difficult here?

>>753829
If it only heats it up... wouldn't there be MANY alternatives to this crappy battery?
thanks for the replies guys.

>>753825
It's enough. It's supposed to charge a big ass (in series) battery. Not give power directly

>>753820
I only need to get the crews out but they're fucked up and impossible to remove by hand. Sucks.

I'll get a drill to get the engine out of the chassis.

That's the blue thing i'm talking about. I'm assuming it's to create a spark for ignition.... But i'd like to not have to carry around a battery. Also the battery is shit and needs to be 100% all the time or else it doesnt start well. Spark plugs arent that difficult.

Also, what the heck is this blue thing? To turn the engine on, i have to plug in this battery and then it works. Any way to make it easier, through some work?

Hey fags, I need some help. I have an RC car (ethanol mix maybe) I want to convert into an electrical generator or PSU in case there's a power outage or something.
That's the first thing. Second, I want to turn it into 100% ethanol. Looked it up but it talks only about car engines, and as you will see in the uploaded pics this is a much simpler setup. Any help would be appreciated.
>TLDR ive removed all radio shit from an rc car and now it's just an engine. How do I convert it into an ethanol power generator?
Also, dubs get

Pussies.

How does ofcom deal with people that bring transmitters to places, turn them on to jam fm, then turn it off and leave??
