This page contains guides&rules and answers to common questions and problems. Every new member should read this information carefully. Guide is kept short to minimize frustration.

Members permissions and responsibilities

Detailed membership options can be found from membership page.

  • Annual member must pay member fee when joining, and following that annually.
  • Monthly member must pay fee every month. Fee must be paid whether or not member is actually using hackerspace. It is paid for possibility to use space, not for actual usage.
  • Every member is recommended to join our hackerspaces mailing list. Guide is supplied in joining notice email. Important announcements from hackerspace usage, courses and other information is send to mailing list.
  • Hackerspace does not have janitor or other hired staff. Members using space must clean up after themselves. Dust and swarf must be swept/vacuumed, and tools must be returned to their places.
  • Hackerspace has microwave, oven, hotplate and coffee maker. Mess originating from cooking must be cleaned immediately, and dishes must be washed.

Community meetings

Monthly meeting is kept every first Tuesday of month at 19:00. If you want to affect hackerspaces operation or acquisitions, attendance is recommended. Community meeting is open for everybody, and it is good chance to get to known with other members. If purchase is decided in meeting (depending on hackerspace finances), organization can compensate payment to purchaser. Meeting agenda can be usually found in scratchpad under meetings. Members can add points to agenda before meeting. During meeting agenda is not edited anymore.

New members are recommended to take a part in least one community meeting, to introduce oneself and get acquainted with other members.

During community meetings formal portion, noisy work is prohibited. Formal meeting usually takes one hour at most.

Storing belongings in hackerspace

  • Hackerspace is not rental storage, so keep only active projects in hackerspace. Take inactive projects elsewhere.
  • Monthly members are allowed to keep one plastic box in storage. Box should be marked clearly, it must include name&nick and contact information.

Standard box is SmartStore Classic 15, which can be bought from many supermarkets and hardware stores.


  • Items outside of box should be clearly named. If item does not have name, it is moved to "bonkki" and can be taken away and/or destroyed.
  • If you have special storage needs, ask permit of exception from administration. Items are stored mainly in storage, not in corridors or workrooms.
  • Tampere Hacklab ry. shall not be liable for any damage to or loss of stored goods on Hacklab's premises.


Hackerspace has many different materials for member use, like wood, acrylic, metal, chemicals&paints, screws etc. Materials are mostly free if price is not indicated.

If your project has leftover materials, it is recommended to leave them in hackerspace for public use.


Hackerspace has near entrance shelves for boxes containing public usage materials and tools. Boxes include at least following items:

  • Tapes
  • Plastic bags
  • Rubber bands and materials
  • Safety gloves
  • Cleaning supplies
  • Extensions cords and power strips
  • Power cords and connectors
  • Power supplies & transformers
    • More power supplies can be found from back storage room, sorted by voltage
  • Video cables: DVI, VGA
  • Video cables: Scart, component, s-video…
  • Audio cables: RCA, plug, jack, tr, trs, xlr
  • TV/Antenna, RF cables
  • IT-parts and computer items: GPUs, soundcards, bluetooth, usb-devices etc.
  • Speakers
  • Metal profiles and extrusions
  • Screws and anchors
  • Stone
  • Velcro and foamed plastic
  • LED-strips
  • Stepper motors
  • DC-motors
  • Arduino
  • Misc electronic items in corresponding boxes

Owned and paid materials

  • If material contains name, it is owned by member. Ask owner if it can be used. Always mark your name to your own materials, or they else are assumed to be public materials.
  • If material has price, it must be paid before use. For example lasercuttable plywood sheets are paid materials. Pay materials to beverage cashbox if not otherwise informed.

Compensation for materials

Even though most materials are free and in public use, it is assumed that members bring compensatory materials to hackerspace after usage, especially if large amounts of material is used. Hackerspaces material storage runs with gentleman's agreement, you are not the only one using materials.

If you use e.g. 15 pcs M3-screws, buy 20 pcs from hardware store, and put them in place. Few parts does not count.

Use your common sense: if M3-screws are well stocked, but M5 screws are out of stock, buy them instead.

If you visit hardware store, or order online, you can ask other members what should be bought for hacklab.

Arno's inventory

  • In corner of electronics workshop, Arno's inventory can be found. It includes some more valuable components, e.g Arduinos, that can be paid in labeled cash box.


Rolls of LED-strips (in different colors) can be found from electronics workshop and from storage boxes. They are paid in LED-cashbox. If some color is running out, order more and ask for compensation.


Bonkki is slang word that means item that is thrown away as unwanted or non-functional, but somebody other sees value in it. Word is originating from radio amateurs and from Alvar Gullichens art

Members can freely take items from designated Bonk-shelf. Members can also bring to bonk-shelf items that can be useful or valuable for somebody else.

Circulation of Bonk

To guarantee that non-useful bonk would not accumulate to hackerspace, it is circulated in three-shelf system around once a week:

  • 3rd week shelf: New bonk goes there. Unnamed items from floors and tables are collected to there.
  • 2nd week shelf: Bonk is still waiting for new owner
  • 1st week shelf: Shelf will be moved to recycling bin

At the end of circulation shelf labels are moved so that: 3 week shelf is empty (previous 1 week shelf), 2 week shelf is labeled as 1 week shelf and previous 3 week shelf is labeled as 2 week shelf.

Moving items from recycling bin back to bonk-shelf is prohibited. Items took out from recycling bin must be immediately brought to home or own storage box.

Good bonk

  • 0–5 year old computers.
  • Industrial and laboratory equipment.
  • Remote controlled, technology containing toys
  • Space, aviation and military equipment. Everything made in Soviet Union.
  • Otherwise cool looking devices, e.g. devices from 70s and older.
  • Retro computing: Commodore, Atari, Nintendo etc. Broken devices are also welcome for repair parts.
  • Non-PC computers: Unix computers, text and X terminals.
  • Generally everything containing interesting mechanical parts, or parts that can be reused
  • Tools, all kinds of tools are excellent bonk. It is recommended to ask if hackerspace is missing mentioned item.

Bad bonk

  • 5-15 year old PC-computers (they are lying everywhere). Older laptops in good conditions can be brought.
  • Large equipment like copy machines and PA-speakers (PA-equipment should be advertised in IRC or mailing list. They will be wanted e.g in cultural center Kuivaamo)
  • CRT monitors and TV-sets (exclusion: Videomonitors, e.g. studio/broadcast grade or C64/Amiga/Atari monitors).
  • Easily available common junk: Set top boxes, ADSL and cable modems, IPTV boxes etc.
  • Dangerous or harmful waste: Broken batteries and chemicals
  • Little technology containing devices: electric ketles, vacuum cleaners, electric mixers, microwaves…

Bring bad bonk only if you have arranged that some body else will retrieve it out of hackerspace soon.


Hackerspace contains tools owned by organization and borrowed from members. (see workspace-page] and [[tyokaluja/start|tools-page)

All tools are free to use provided that member knows how to use them without breaking them. If you don't know how to use them, ask for help. After use, tools must be returned to their places CNC machines need monthly membership to be used, and also small course about basics before you are allowed to touch them.


Some times something goes broken. If broken item was valuable (in tens of euros), report it to administration and compensation will be negotiated.

Drill bits snaps often. If you break them in large quantity, you should buy new set to hackerspace and it will be acknowledged by that.

Also bandsaw blade snaps sometimes. You should not take it too seriously, but inform administration or somebody that knows how to change the blade. It is important that machine is not out of operation needlessly.

Borrowing equipment

Monthly members can borrow tools for brief periods. If you borrow something, lEave a note in place of tool containing your name and phone number, and when you will bring back the tool. For longer periods (several days), also inform administration with email.

Making noise

Hackerspace is meant for building, so making noise is allowed. We are located in industrial building where noise is not problem in any time.

Exception is courses and meetings that are announced beforehand: During them making loud noises is prohibited. Quiet work is allowed, e.g. electronics building. Lecturer has right to ask to stop any work that disrupts course.

Always close the doors of wood/metal/plasma rooms if your working causes noise. Always wear appropriate hearing protection.

Beverages and fridge

You can buy beverages and possibly other goods from fridge. Catalogue and prices can be found on the door of fridge. Unidentified beverages (e.g. unamed 1.5L bottles leftover from events) from are free

You can store small amount of own drinks and food in fridge given that they are named properly. Fridge is small so it can only be used as temporal storage.

Beverages and goods are payed in wooden cashbox near the fridge.

Only human consumable items in fridge!

Beverage account

For avoiding use of coins you can pay beverages beforehand. Fridge door contains list where you can put your name, amount of money in account and bought beverages. Bought beverages (in euros) can be marked as

tally marks.

In community meeting it is decided that beverages are always paid beforehand - no debt is allowed'.

Improving hackerspace

Hackerspace follows Do-cracy method. If you want to improve hackerspace, just do it.

If you have suspicion that somebody is not happy of idea you have, ask from other members what they think of your idea of improvement. If idea does not please others, it is better to be left unimplemented. Larger and money involved changes must be always approved by administration or in community meeting.

General guide: Use common sense


Dying or seriously injuring anyone in hackerspace is forbidden! First aid kit is located in visible place, make clear to yourself where it is located. Various personal protective equipment are located around hackerspace, you must use them appropriately when there is possibility of hazard.


Hackerspace is equipped with CO2-extinguisher, several powder extinguishers and fire blanket. Notify yourself of their location especially if you do work containing hot items.

In case of fire, use first CO2-extinguiser, if it is possible. Powder extinguishers cause terrible mess, often worse than small fire would have caused. (all equipment must be opened and cleaned thoroughly, all porous surfaces will be permanently infused with powder and it will damage items.)

Window can be used as a second fire escape by breaking it with supplied hammer. Fire escape ladders are located outside of window, at the left.

Charging lithium-ion batteries and usage of low quality chargers must be always done under monitoring. Leaving batteries charging alone is prohibited.

Dangerous materials and items

Following items are forbidden unambiguously:

  • Ammunitions and explosives. Servicing guns is approved, but leave ammo at home.
  • Working, handheld illegally powerful lasers. Can be identified often by color other than red. Powerful lasers are OK in enclosed devices e.g. laser cutter, where protection is in order.
  • Radioactive and otherwise very toxic materials. All unidentified and unlabeled chemicals should be considered dangerous.

If you notice any of there, notify owner, administration or emergency services depending of situations severity.

Commercial activity

Commercial activity (e.g. making products for selling) is allowed in hackerspace, if it is small-scale and does not disturb other activities. If you are doing commercial work in hackerspace, notify administration and make agreement. Compensation can be monetary, products or e.g. public course of the topic.

All materials used in commercial work must be compensated for, and usage of CNC- machine time may also be needed to compensate.

E.g. We have charged basic electronics work done for business 10€/hour. Person doing work must be member of hackerspace.

Commercial work should be timed for days when hackerspace is not crowded. Example long 3D printings are not recommended at evenings when there are other members at present who would also want to use said printer.
