agenda
tracing electricity
yesterday looked at switchboxes LP and jimmy have been trying to trace circuits with llama's help
three 120v circuits - green, blue, orange wrapped outlets with different colors
green is most overloaded (mostly 3d printers) orange is mostly fans
Next step is trace out from the box - there are many free circuits.
Also need to figure out the voltage going into the box.
The switch in the front probably 3-phase 240V. Will trace tomorrow.
Switchbox off the lift is wired differently, unsure if its 120v or 220 fused into single-phase. Will lookup the model of the lift to see what its getting.
We can maybe get voltage stepdowns to use the 220 circuits as 120s as needed, now that we know what is what.
We can try and find more 120s by tracing from the box. Hopefully we don't need to run wire.
Fridges in the front, think its blue or green.
micro: So we want to balance the boxes?
jimmy: yeah if we can't find more lines, definitely.
we can also remove or hide outlets for things that are highly loaded.
llama: we can use common sense
for the sake of coffee roaster, you could share with the range, as they are not on at the same time. Also can be shared with the lift.
jimmy: range is 120?
llama: 220
next step: balance between these three lines: - coffee roaster - CNC machine
saturday antenna workshop report
llamma: great success - pictures on the signal and nextcloud
made 6 - 3x 16, 3x19" (with a little Y-shaped) copper pipe, they look really cool
actually welded all the tubing in the basement
there was a blowtorch. no one hurt themselves during that session.
micro - we don't have a first aid kit in the basement
llama - yeah we don't maybe its a good idea
copper pipe got too hot, had to use one of jessies wood to place on top of our table and made burnt wood art
this was for HF, not UHF
the 40m antennae requires electronics, using a very DIY kit from china. Unwrap wires, put 3 together, put shrink wrap to make 1 wire, then wrap 7 times exactly. Maybe 6 solder points total.
Problem is the box is difficult to work with, you need to drill into it, and its too small so I drilled into my hand.
Next day spike when to BCF to test it out, needed a bit of trimming but it works now.
micro - how long
We thought it would take 2-3 hours but it took 6 hours
flora - what were the 3d printed parts?
copper antenna has two different routes that come out, to prevent them from hitting against each other, we put like a plastic spacer in between them
i wish it would take less time in the future
also there is some risk - drilling, welding, blowtorch.
micro - could you run this class again?
if the 3 students got together we could
but the tester spike had is non-trivial to obtain. but everything else is trivial
flora - do you think itll still take 6 hours?
maybe it would be a little less
micro - maybe do 1 antenna?
2 very different skill sets - 2 different kinds of soldering
social media
we've got mastodon runnig but noone uses it
micro: made instagram acocunt, woodbine.basement.
15 followers!
just want to post cool pictures from the space
q: question for photo policy? - maybe not face - circuit boards - get permission - take down photos if people as you to
shared credential organized by micro, if you want access go ask micro
want someone who can do writing, caption
maybe an annoucement of who we are and when we meet
will go very very slow
flora: - have to do social media for work, so will help out
credential is shared in signal
post whatever

he is not here he doesn't want to share this
devin needs a job, please retweet

would be nice if devin can give a 30 minutes to 1 hour explainer class on kubernetes
updates
micro - pen plotter is funky, and working llama - if there is another revolution, i hope its against buearocracy. i will do all i can afford flora - isolated at home doing nothing lippe - no updates, all relevant stuff posted in matrix
