Taiken avustus työtilan kehittämiseen ja tapahtumiin

Helsinki Hacklab has received support from Arts Promotion Centre Finland (Taike) in March 2017. The 5 000 euro amount will be used in developing our workspace, helping the hacklab.fi coordination network and in participating SHA2017 event in Netherlands. Workspace improvement topics include storage organizing, indoor and outdoor lights, accessibility and chemistry workstation.

Taike logoTaiteen edistämiskeskus Taike myönsi Helsinki Hacklabille avustuksen työtilan kehittämiseen, hacklab.fi:lle sekä kotimaan ja ulkomaan tapahtumiin. Avustuksella voidaan organisoida työtilamme entistä paremmaksi, valoisammaksi, sekä huomioda esteettömyttä ja viihtyvyyttä. Avustuksella voidaan kehittää myös varastotilaa, kemian työpistettä ja koulutushuoneen käyttöä.

Osa avustuksesta on osoitettu hacklab.fi-yhteistyöhön, tapahtumaosallistumisiin ja omaan HSF2017½-tapahtumamme Helsingissä (Robotit Strömbergin puistossa). Haimme tukea myös SHA2017-tapahtumaan osallistumiseen.

Helsinki Hacklab kiittää avustuksesta, sekä erityisesti hakemuksemme lausuntojen kirjoittajia suuresta avusta!

HSF 2017

Last weekend hacklab.fi got together for the biannual Hacklab Summit Finland weekend at Tampere Hacklab. We usually try to make some plans together for the following year, so this time we made an easy decision to sign up for a shared Youtube account (will be announced later), had some talk about SHA2017 and shared thoughts how things are going on in different cities since we last met face to face.

Hacklab.fi has a tradition of robot competitions, and there are replicas of the standard maze course in Helsinki, Tampere and other cities too. This winter’s competition had eight autonomous robots that had never participated before in any previous races. As usual, strategies on the track varied: ultrasound sensors, color recognition, wheels, walking with legs, laser-cut plywood, Arduinos, Legos, 3D-printed parts and recycled materials – and also a logic-less build up with motors, wheels and batteries stick together with hot glue. Piispa by Vurpo @ Turku Hacklab won the race this time with fastest lap.

This years program included a visit to the recently started Finnish Museum of Games and to meet an association that does anything related to VR tech. A nearby band surprised us with an unplugged gig next to our trailer sauna at about 3 or 4 am. Turku Hacklab has restarted the LED party hat project, which has been in hiatus for too long, so we soldered few example boards to test out the new PCB layout. We flew FPV drones and also fixed some hackerspace management software problem.

Helsinki Hacklab got a excuse to dump donate excess components and materials to other labs, including our extra vending machine. We shortly met with some folks from Lahti, who are thinking about forming a new Hacklab in the city. Hacklab.fi hopes it can support Lahti with this project!

20170128_robokuvahsf2017Thanks to Tampere Hacklab for hosting us again, and see you all in Helsinki this summer for another HSF.

Hacklab.fi 2017

Shortly in English: Hacklab.fi co-operation network gathers at Tampere this weekend for robot competition, making plans for future and having a good time. Another similar event is organized in Helsinki Hacklab later this year.
We are looking for interested people to join us for SHA2017 camp in August. The event takes place in Netherlands and organizers expect about five thousand people across world to come there. Our IRC channel is #sha2017.fi @ IRCNet.

Hacklab Summit Finland 2017

HSF järjesteään Tampereella nyt viikonloppuna 27.-29.1.hacklab.fi logo

Mistä on kyse?
Hacklab.fi on Suomen hacklabien yhteinen verkosto, joka kokoontuu kaksi kertaa vuodessa säätämään kaikenlaista yhdessä, kisaamaan roboteilla ja tekemään suunnittelemia tulevasta.

Paikalle voi tulla myös vain pitämään hauskaa yhdessä, vaikka lennättämään quadkoptereita tai saunomaan. Tänä vuonna tehdään vierailu Suomen Pelimuseoon.

Kevään ja kesän tapahtumia

Helsinki Hacklab ja hacklab.fi osallistuu tänäkin vuonna suunnitelmien mukaan seuraaviin tapahtumiin:

  • Model Expo 2017, 21.-23.4. – Tule tapaamaan Hacklabeja osastollamme. Expoon lähtee myös Suomen Avaruustutkimusseura.
  • Järjestämme Helsingissä kesällä vuoden toisen HSF:n. Ajankohta täsmentyy myöhemmin.
  • Assembly Summer

SHA2017

SHA2017 logoKeräämme porukkaa lähtemään elokuussa Alankomaihin SHA2017-leirille. Kyseessä on Keski-Euroopan tämän vuoden suurin maker/hack/yms. -kulttuurin tapahtuma, johon odotetaan osallistujia joka puolelta maailmaa. Esityksien, pääohjelman ja workshoppien lisäksi leiritunnelmaan kuuluu oleellisena osana osallistujien itse tuottama ohjelma ja tekeminen leirialueella – ja yliampuvat LED-valaistukset.

Suomesta lähtevä joukko kerääntyy suunnittelemaan osallistumista IRCNetin kanavalla #sha2017.fi, jossa mm. pohditaan omalle leiritontille yhteistä isoa telttaa ja saunaa. Tähän mennessä listalle on saatu n. 20 henkilön lista kiinnostuneista lähtijöistä. Leirille odotetaan yhteensä 5 000 – 6 000 osallistujaa. Vastaavanlainen vuoden 2015 leiri Saksassa näytti tältä.

Uploading photos to Flickr from Eye-Fi card with Raspberry Pi

Helsinki Hacklab’s policy for photographing sometimes puzzles our guests which might come from other hackerspaces with limitedly allowed or strict rules for taking photos, for privacy reasons or some others. Back in 2014 we still had very scattered collection of photos by individual members, maybe hosted on their own homepage or somewhere else, until lost forever. To preserve our history better and and have more up-to-date content online, we decided to make both taking photos and publishing them as hassle-free as possible. So we bought then an Eye-Fi card along with our camera and configured it so that all photos are automatically published in Flickr anytime the shutter recloses. So far, no complaints.

kuva kamerastaBut now, Eye-Fi has announced shutting down its service, which we have used for uploading over 4000 photos during the last 18 months. The X2 product line (and some other models) that are affected by this shutdown have still been sold in 2015. First card we had, a 4GB SanDisk branded version, failed this summer, but luckily one member had an unused X2 Connect somewhere, so we were soon back posting more photos of our weekly activities and blurry accidental snapshots of our feet. But, to continue using this Wi-Fi SD card after the service shutdown, we needed a replacement solution for both getting the photos from the card and sending them into our Flickr photo albums – and maybe making some improvements too.

RaspberryPi 3 in our tele rackWe had just received a bunch of Raspberry Pi 3 boards and tried to figure out what we could do with them, and because model 3 had Wi-Fi capability, connecting to Eye-Fi card could be done using eyefiserver2 project. For Flickr upload, I chose using Flickraw library for Ruby, which seemed to be a well-maintained project, so that possible future changes in Flickr API should not be a problem.

First, eyefiserver2 process is started on startup, this gets the photos from the card into RasPi, then every 5 minutes a Ruby program is run, which uploads new photos and marks them published.

The project (or step by step tutorial) can be found in Github:
https://github.com/HelsinkiHacklab/eyefi_flickr_auto_upload

We previously had all our photos ordered in albums by their date. One thing I wanted to improve was to put photos taken between 0 am and 3 am in same album with photos taken on the previous day, which makes less time line discontinuation when viewing photos by start date of an event. The Ruby program also by default renames photo titles by their timestamps. See our Flickr page for results.

In our setup, the RasPi is connected to Internet using Ethernet, and only the Eye-Fi card’s internal network name and password are stored in known wireless networks. If the camera is used outside our Hackerspace, and there is an Ethernet port for the RasPi available (maybe shared from a computer), we should be able to keep publishing photos from ongoing events, happenings, fairs etc. as we usually do. This is different from Eye-Fi center we previously used, in which we configured the card to know new local Wi-Fi and its password. This task required someone (which is me) to have Eye-Fi Center program first installed, and was usually a dull and slow thing to do during ongoing event or buildup. Now we just have to remember to take the readily configured RasPi with us anywhere we go with the camera.

If you don’t have an Eye-Fi card and would like to build a similar auto-publish system, I can’t say if it’s a good idea to buy an aftermarket Eye-Fi card anymore. Configuring this setup requires user to obtain card specific information that might need Eye-Fi services to be available (you cannot login to or create a new Eye-Fi center account after Sep 16th). If you have the card, but don’t really know what to do with it after Sep 16th, go enable its internal wifi (direct mode network) and store the password and MAC address for possible later use while you still can. If I’ve understood correctly, also the current Eye-Fi product line does not offer Flickr publishing. Try googling “hacking transcend wifi sd” for more ideas. Check out FlashAir API guide https://flashair-developers.com/en/.

(2016-09-01) Yesterday Eye-Fi announced a new tool for older cards, which might help to get card Wifi and MAC information after Sep 16th, which are needed this for python server solution.

Piensarjatuotantoa CNC-jyrsimellä

Update 2016-03-28
Rambo has posted a step-by-step report about this CNC-project. See pictures and information here: thread @ Hacklab Discourse.

Regulaattorin sovitus prototyyppiin

Regulaattorin sovitus prototyyppiin

Rambo on suunnitellut ledinauhojen regulaattoreiden koteloimiseksi alumiinista jyrsityn palan, jonka sisälle regu mahtuu mukavasti ja regulevyn komponenttien kohdalle jyrsittyihin koloihin. Yhdestä alumiinikangen pätkästä on ohjelmoitu usean samanlaisen laatikon jyrisntäradat vaihtamalla koneen koordinaatistoa töiden välillä.

Regulaattorit liitetään myöhemmin kiinni ulos sijoitettaviin ledivaloihin. Projekti on ehkä tähän mennessä suuritöisin Lotalla tehty työ, ja sen etenemistä voi seurata Flickrissä. Samalla on tullut testattua syöttö- ja nopeusasetuksia eri työkaluille ja katkottua paksumpi leikkuuterä.

Moving to Takkatie 18, a status update

Helsinki Hacklab is moving to a new address, Takkatie 18, during the end of 2014. We expect most of the work be ready in November, but before that, we are renovating the new location. This means that there are cancellations and exceptions in our regular weekly meetings. If you plan to visit us, please bear in mind that we might have not much time to keep this website or other information up to date, so be in contact with us beforehand and we can tell you the current situation.

Renovating Takkatie 18 in progress

Renovating Takkatie 18 in progress

Yesterday our members were at Takkatie planning the use for rooms, checking places for larger items and doing general renovating work. This weekend is going to be major moving of all our stuff, and we need as many volunteers as possible to participate.
