With corona largely behind us we face an old enemy - creeping debt. The iriya found new necks to squeeze, namely mine and that of AL, by means of putting holds on our bank accounts and thus preventing our participation in various capitalist enterprises. Having shaken us down for 10000NIS for this years arnona at shooken, they are after another 60K NIS for KG45 , our game of chicken coming to a fore in these days. The iriya's intransigence has managed to break the spirit of one of the last standing stalwarts, and the imminent closure of TAMI was announced. For real this time, you ask? There's not much money left , the wolves are at our backs, we've deferred a month's rent from our landlord, the sharks are circling, and in general it would appear we are SOL. You who read this, look deep into your hear and your pocket, and transfer all those bitcoins. DONATE
I've been busy since 2018 but am back to report on a mystery from the nasa mars lander vid I think there's a msg in the parachute
The thing is there's only four bits per parachute sector, so how would you write a message (eg in english chars which need a 26 char alphabet). If you had 5 bits that would be perfect. Maybe every 10 sectors (which gives 40 bits) is split into eight 5-bit words? If you just convert as binary it doesn't seem to scan.
We had a visit from Eli Mizrachi and abt 5 women from the Iriya. They looked around , specifically asked for the lathe/mill, checked out the biolab (which is looking better every week) and left after abt 20 min - there was no clear decision or conclusion. Hopefully they got the picture that the place is not only not-for-profit but in fact an excellent money-pit ...

Avi has been hard at work upgrading the new gallery (that he built in place of the glass room) . He brought a bunch of storage trays which fit under the gallery, sliding into place two deep. Check it :
Master planner that he is, the distance between beams exactly fit the container dimensions, allowing for ceiling storage that will launch the hackerspace into 2019 with guns blazing (metaphorically, we don't condone such, although neither do we categorically condemn, preferring a Swiss position on this and all other matters political). Huzzah!!
visitor from the gdr turned me on to the stuttgart shackspace - check out the arduino board ---
alon and tami (the human one) make shelves
tami meeting. we need some donors/alt income sources. outgoing ~11kNIS/month incoming ~3k/month -> sugar daddy coughs up 8kNis/month which is very bad for angels with finite bank accounts
massive cleaning at the metal shop!
MASSIVE ORDNUNG PWNED
1. cables&connectors : wooden 'hive'
2. computers & random non-cable non-connector electronics : white metal racks on SouthEast wall
3. non-electronics& personal stuff: white metal racks to left of entrace when entering
at-tami bakeoff. the attami can act as a keyboard/mouse emulator. a highly useful device now exists that , when connected to your usb, types the following every minute:
Now, this is the story all about how
My life got flipped-turned upside down
And I'd like to take a minute, just sit right there
I'll tell you how I became the prince of a town called Bel Air
Eran is nearly done with his bike trailer . He made this nice weldingrod holder , found a nice vise for the welding table, and also grabbed about a half ton of metal stock from Donde's bike cart shop that's closing its doors :<
Dr. Norbert came round for part 1 of his ecorenovation series. We got some insider recipes and theory on ancient techniques that have gotten lost with the advent of 'plastic building' - latex paints amongst the offenders. We resurfaced a wall - it came out pretty nice and was rather easy to do.
The kg45 bldg had an artshow with some intstng pieces utube [mediagoblin offline]
This character has been showing up again lately, with the general result that stuff is getting done, shelves re going up, and some 'freedom cleats' may eventually get made if the hackerspace doesn't get in his way too much.
This character with the maniacal grin that is usually hidden by an orbit-worthy respirator has been doing these nicely finished parts for an automatic food rehydrator and cooker (think coffee capsules with food instead of coffee).
gingi here is working at the 'new' central bus station refurbishment and for this purpose has engineered the following pallet deconstructor
amusing tami quotes
'if you managed to make a deal with maxwell's demon, the real devil would be your bitch...' - d. klein
'as an adult i still think I can do anything, I just have a better estimate of how long it'll take' - a. levy
srsly pplz. attami rulz the hauz. theres nothing like the smell of cheap chinese solder paste in the afternoon - smells like temporary victory over the forces of entropic dissolution. Kudos to the wire-haired genius that made this all happen - Zvika, Yair, Guy, and Udi for long and careful work on design. Zvika for his kind of amazing arduino-controlled solder reflow oven complete with door-opener, reminiscent of the 'useless machine' insofar as it turns itself off, but is contrariwise eminently useful. Yair got the boards made, fixed the bugs, obtained all the components, made a solder mask using the stencil machine he also obtained for tami, etc. etc.
How do we do this, you ask?? Here is my step by step:
These are the bare boards before dicing. Slice one out.
Yair made this solder mask using the stencil cutting machine
Put the attami board in the jig and smear on some solder paste thru the solder mask.
Then scrape off the excess, doctor-blade style and start adding components
from the the convenient component box according to the latest layout
Note these parts are TINY
Keep going with the components, do not give up.
Once the board is populated, check for errors
and pop it in the oven for reflow. Turn on heating elements, max temp and max time, hit reset on the computer ps zvika hacked.
After the reflow is done add a little jumper from X to Y
now you ready for program, boy - using the 'isp' and this crazy contraption
which is spring loaded!!! connect!
yair haz teh codez 200px make blinken fur die checkenprotokol
Some folks from a robotics class in a local high school came by with their guide and built some robots. This is for some sort of competition for robots that do pick and place I think.
Tami got a motorizd movie scren (it rolls up, one that drives around would be good but maybe inconvenient for the viewers , unless they were also rolling) thanks to Amitai who reworked jerem'y primitivist attempt. I am a sparkplug, ignitor of idea-storms. Anyway at this point the thing actually works, the beamer is now on the central pillar which also got an upgrade by Yair Jeremy and Amitai.
Yonatan the Gingiest hacked a skateboard by adding a carbon fiber layer - actually too stiff but still way better than the original.
Jeremy looked at a cockroft-walton voltage multiplier that was assembled wrong, and tried putting a single stage together correctly, no dice. Would the driving frequency affect the output voltage for some reason?
The midburn IT team had a really groovy hackacthon. An impressive roster of folks contributed their time and expertise to get a pro site up which can be used by other regional midburns (these are burning man local events timed between the main burning man event.
check out a timelapse here

1. customizing drupal cod (https://www.drupal.org/project/cod) for a ticketing system (to be open and usable by other communities when ready)
2. writing 'inspiration' - http://staging.soulbounds.com/burn/
3. various other things (SEO, wordpress security review, moving to AWS)

will stay at the space for now to drop some beats.
Dr. Norbert Hoepfer Workshop once again
JF created a chopping board with recess to allow destination-plate to be put in position so that chopped pieces can be output directly onto plate
DK amused the masses with CD-in-microwave antics
N reconstituted a vintage makineta type device
Zvika figured out the electrical problem.
Soon we'll try to map the circuits and put them e.g.
Since the 'difference' fuse was jumping we look for a leak to ground.
To test connectivity between physically remote points (i.e. the output of fuse 5 and a suspect 'hot' wire) you can
run a long wire from the output of the fuse (in the main electric box) to a DVM, hold DVM near suspect hot wire and test resistance between suspect hot wire and output of fuse.
