六角大王
a 3d modeler that once existed in japan
production has already ended

i keep feeling more “future”
in those old snow white macs

that whole system of forms
still outpaces anything recent

i made up the insides of a tachikoma
kinda fun

ideal heat curve
0–7 low
7–9 medium
9–20 high
20–22 medium
22–28 low
28–30 very low

without the aluminum inner wall
hard to get this

just carbon felt
about 20 min on 0.5 oz

not bad at all
but the heat curve drifts off from ideal for rice

adding the aluminum inner wall
was a good call

just need something
that doesn’t push the felt too hard

burn curve on this one
low → medium → high → medium → low → very low

timed for rice

probably not great for the felt
so just watching it for now

stopwatch in hand
timing each phase

this kind of trial and error
is kinda fun

this stove
has an aluminum inner wall
to control vaporization

it works

but it traps more heat inside
and the carbon felt wears faster

tried a bunch of setups

thought more carbon felt
would mean better burn time and output

but keeping it just dense enough
to barely hold the fuel
makes vaporization easier to control

CF stove for rice
in an Esbit setup
turns into something else

just about half an ounce of fuel
and it’ll run for an hour

more like simmer / keep-warm now

tapioca starch texture’s really good

kinda nice

still — the stove alone can’t do the full cycle
it only works once you pair it with the right pot stand

even just tweaking the slit length a bit
and the whole thing starts behaving different

kinda why it’s fun

the heat curve got smoother than a normal alcohol stove
but dialing in the timing was still kinda messy

ended up adding an aluminum inner wall at the boundary
just to mess with how the vapor moves

and that finally started to click

always felt like there should be a stove that can actually follow that
but nothing off-the-shelf really gets there

then i saw someone building one with carbon felt
and yeah… that was it

i’d been lowkey annoyed with how hard it is to control heat on alcohol stoves for rice

you need that curve — low → medium → high → medium → low → very low
and timing to match it

inline layout — everything aligned
air just goes straight up
clean chimney pull

less dramatic, more controlled
oxygen stays steady, burn stays steady
this one just holds the 25 min curve

vents offset vs inline

offset layout — vents slightly staggered
air cuts sideways a bit
fuel and oxygen mix a bit harder
heat jumps fast, boils quick

doesn’t really stay there tho
long low-fuel runs get kinda unstable
heat stacks up… then drifts

today’s batch

aluminum ended up being the most stable
burned over 5 minutes longer than the others

paired with this tiny square cooker (about 0.5 cup)
it just works
and yeah… kinda cute
