### 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

|
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 |
