¶ Scope
Come to our hackerspace hackathon and bring your own ideas and projects that could use some momentum. You don't have to be a hackerspace member or focus on hackerspace-related ideas.
Also, there's no pressure to create a startup, build a minimum viable product (MVP), or anything of that nature. Instead, we're returning to the essence of hacking: enjoying a weekend of tinkering with things we love, surrounded by amazing individuals!
Bring your sleeping bag for sleepover. There are some couches available for crashing and there's a shower available as well.
Take a look at the Paths below and add yours below or to this pad!

¶ [Your name here]
- [Your ideas here]
¶ Vad
Laser cutter calibration block as keychains, engraved with width on each + keychain holder board to put next to l-cutter
¶ Artur
Add SpaceAPI to k-space.ee
¶ Arti
- Access path: Add keep door open button for X hours to inventory/doorboy webpage and corresponding slack command (adding a brick to the door is stupid)
- Management path: Price adjustments
¶ Erki N
- Management path: Price adjustments
¶ Erki A
- Infrakube path
- Maybe Space path: Replace full-height closet with the 1/3-height under the table
¶ Lauri
- Print signs for workshop, 3D printers etc, https://imgflip.com/i/8xew9r
- Space path: Reverse engineer low level signalling of the flip-disc displays to start designing ESP32 based driver for them
- Infrakube path Update, upgrade and clean up hackerspace server hosting infra components
- Are we affected? https://www.phoronix.com/news/OpenZFS-Encrypt-Corrupt
- Access path: Lukukoda
¶ Ott Joon
- Figure out Flipper Zero SDK and write an application for it
- Measure TETRA signal strength on the Flipper to sorta kinda understand how close emergency services are to you.
¶ Priit (plaes)
- Retro path: Macintosh emulator
- And maybe some woodworking - arcade deathmatch game
¶ Sander Trumm
- Space path
- Filament drybox
- Put Klipper + Fluidd on the MK3S+ (maybe camera too?)
¶ Rasmus
Vending machineDelete VM 391 dc1.k-space.eeCount/document light switches for Shelly order.TODO: Order- Management path: Billing system
- Supporting chaos monkey in Infrakube
- Access path: Keys
- Vending machine: Find A/C person
Bonus: Install architecture lights (mainly unified on/off)- Bonus: Find a victim to make the vending machine talk to one of 2 possible cashless protocols. Apparently you can remotely (quicker / spreadsheet sync!) set prices via coin module. *** Doorkey would work for (credit) payments, but for (QR-code) LHV Connect (bank lightning transfers) does it timeout, or can you add credit before selection (and what about timeout refund transfers)? Very bonus-bonus: Sales statistics.
- Q: K-SPACE at BSides 2024, I'm not present, but who is, what is the plan, nocom at the organizers?
¶ micro
- Rewrite my ancient SpaceAPI map (https://spacer.nooitaf.nl) in golang
to celebrate k-space being finally on it, hopefully
- Work more on reverse engineering embroidery machine's machine-code
¶ Artjom Kurapov
- ESP32 + sending sensor data (temperature, weight..) for beekeeping app (gratheon.com)
- telemetry API microservice -> influxdb
- grafana visualization -> influxdb
¶ Paths
Based on https://pad.k-space.ee/p/members-todo, see for more details!
¶ Infrakube
- Restore normality (see members-todo 'Kube') + docs
- Core switch configs
- Argo in sync
- Clear up https://prom.k-space.ee/alerts and review prom targets.
- Upgrades: Calico, Traefik, Kube
- Demolish storage workarounds
- Document architecture (+ non-Argo in detail), backup strategy. Product owners.
- PVE-side kubernetes chaos monkey
- App features:

- Migrate Gitea to use native OIDC
- Mail spam filtering
- Restore Machine lists/inventory from router
- Testing/monitoring for OIDC login fails. Selenium?
¶ Management
- Membership (re)package(ing), announce price adjustments
- Bonus: billing/membership system
¶ Access
- Lukukoda:
- (Please keep copies of keys as low as possible. Less tracking, less chaos.)
- Replace workshop lock, forcing use of keycard.
- Server room electronic lock + swap keys. Erki has clone certificate, what type is the lock?
- Green-gray cupboard outside of workshop door: Replace lock, possibly keep it non-lockable.
- TODO: Lockers: 1 backup + 1 main key for each.
- Larger (digital solenoid?) key locker.
- Keys audit. Merging multiple lists.
- Rules/procedures for taking and cloning keys.
- Ensure backup key in the hands of ErkiN for antisocial room
- Workshop machine access control + log (especially for lasercutter outside workshop)
Cameras:
- Replace camera backend with https://docs.frigate.video/frigate/hardware/ or https://kerberos.io/
- Plan new spots
- Wiring for new spots
- Order hardware
¶ Space
- (External: Vending machine A/C)
- Server room
- Bolting racks together (floor load bearing)
- UPS emergency shutoff wired to building fire alarm
- (External: Server room ventilation)
- Hot/Cold aisle
- Chaos

¶ Retro
- Clean up network share for DOS/Windows 3.x computers
- Terminal server retro share Samba config to Ansible
- Breathe life in to more machines (examples?)

¶ 2024-07-26
- @Rasmus inventoried lockers and their keys with help from @Madis. Lukukoda list ready.

ottj: statistics for propietary radio protocols
Alex
looking for people to hire, Wordpress-Magento
Replaced their Italian company with an Estonian one, ended up moving to Estonia
first time today
Leading in a large discussion group.
Lauri generated home-made ice cream, 3 liters of milk, 600ml curd cream, 4,6 kg of ice cream dough, 5+ liters.
Philipp and Tommy helped out Michele with Pizza. Philipp is thinking of working on cashless payments for Vending machine. Tommy was excited to find out there are featured paths in this years hackathon. 4 kg of dough, 27 pizzas.
Kristjan SLIP: IP over serial over radio
Erick is getting better at Gran Turismo
Agis, visiting, 3y ago member: kids and moved to other side of Tallinn
Jen is interested in building furniture with workshop tooling (mainly CNC).
Rasmus continued the serial interviews.
¶ 2024-07-28
Lauri and Erki upgraded lots of Kube infra parts, improved ansible playbooks https://git.k-space.ee/k-space/kube
Erki started cleaning up Kube infra
Lauri investigated further the flipdisc internals. Uploaded Sigrok Pulseview dump to https://wiki.k-space.ee/en/projects/flip-disc
Overall signalling is somewhat complex (20pins) and uses lots of low level electronic components (NAND dates, 1-to-16 decoders etc). Considerig going back to the original controller board, need to investigate whether the firmware could be decompiled etc https://git.k-space.ee/k-space/mobitec-tools/src/branch/main/firmware
Maybe the baud rate can just easily be cranked up from 9600?
lauri nvidia tegra?
plaes will maybe add cameras to workshop
