Samedi 13/06/15 : Conférences sur les Déchets d’équipements électriques et électroniques

Un nouvel épisode dans la série des conférences organisées par le /tmp/lab dans la grande Médiathèque.

Au programme : Cyril Desmidt, membre de l’association Electrocycle, l’asso D3E et gérant d’InfoGnuEureka, nous présentera le recyclage de tous ces déchets dits D3E. Derrière cet acronyme abscons se cachent les Déchets d’équipements électriques et électroniques dont la quantité produite annuellement ne cesse d’augmenter. Voici sa présentation :

Qui s’intéresse à ce que devient une télévision lorsqu’elle arrive en fin de vie ? Qui a déjà entendu parlé des déchets d’équipements électriques & électroniques ? Qui s’est intéressé à la couleur des poubelles et a réfléchi à ce qu’on est sensé ou pas y mettre dedans ? Qui a déjà essayé de faire rentrer une grande télévision dans une petite poubelle ?

Electrocycle, l’Asso D3E s’est intéressée à quelques unes de ces questions ainsi qu’à d’autres. Retour de terrain sur ce que nous avons expérimenté et de ce que nous avons compris.

[Pour ceux qui se demanderaient, non nous n’avons pas essayé de mettre dans une grande télé dans une poubelle.] Mais, nous avons pu constaté ce qu’il arrivait aux télés laissées sur la chaussée…

Cette conférence gesticulée sera en partie le résultat d’un brainstorming dans un lieu qui a décidé de ne plus accueillir d’écran CRT. Merci par avance aux futurs participants d’un certain atelier. Elle est la suite d’une proposition avortée qui s’appelaient : les D3E, ils n’en ont pas voulu !!!

Et la forme ? Une conférence gesticulée qui comme chacun sait est “une forme scénique mélangeant du savoir froid sur un sujet, et notamment de la radicalité (revenir aux racines de ce sujet), les histoires de vie des conférenciers-gesticulants par rapport à ce sujet, de l’humour et de l’auto-dérision, et un atterrissage politique (ce qu’on peut faire pour agir sur ce sujet). Il faut donc prendre le temps de ramasser de la matière sur chacun de ces fils de la conférence gesticulée puis de les tisser entre eux.” Si vous l’aviez manqué, il est toujours temps de regarder : Franck Lepage – Incultures – L’éducation populaire, monsieur, ils n’en ont pas voulu – 16 mars 2011

La conférence sera ponctuée de petites interventions dont nous vous réservons la surprise, accès libre.

Fix Your Symbols

This Saturday I continued with the commissioning of my unified singing pumpkin controller. I got all the sub-systems working except for the power amplifier. In the picture above, on the left is the pumpkin controller. On the right is a (normal) Arduino amplifier shield using the same amp chip.  That shield works. If you look carefully you can see that the chip pins are mirrored between the two boards.

Mirroring pins is an innocent enough mistake. It happens to everyone once in a while. The problem is that I made the EXACT same mistake on the first round of that amplifier shield. (Notice the R2 on the right hand silk?) Apparently I fixed that problem manually without correcting my library symbol. That was many months ago and I forgot about it, thus resulting in a repeat of the same error on the unified pumpkin controller. Dumb mistake! It would have taken 10 mins at most to fix the symbol.

Don’t be like me, fix your symbols the moment you notice the mistake! You may not get back to it for a while and may not remember there was a problem.

Fixing TOG’s drill batteries

TOG’s drill batteries were on their last legs. We were barely getting a few minutes of use after a charge. Time for some new batteries. Two new batteries were almost the price of a new drill, so we looked at buying a brand new drill. There was nothing wrong with the old drill …. just that the batteries were bad.

After a bit of searching on the ‘net, a set of 12 new cells was on its way to TOG for just €15. The battery pack was opened up and the old cells removed. The new cells were fitted with the same layout. Lots of pics here. After reassembly, the battery charged fine and the drill is back in action. Just need to do the second battery now.

Kickstarter campaign success!

“It’s hard to overstate our satisfaction.”

THANKS TO YOU and 213 other backers, the Nova Labs campaign was a huge success! We surpassed the goal, raising over $23,000, and will be outfitting the classrooms with new furniture and A/V equipment. These completed classrooms will allow more people to rediscover the joy of making things!

If you backed our campaign:

We’ve updated the Kickstarter campaign with a more detailed version of this post, including some ‘next steps’ for us, and what you can expect. You can find that update here.

We still need your help!

In the coming weeks we’ll be working to fulfill our backer gifts: there are keychains and airplane kits to laser cut, Blinkyduino boards to assemble, and lots of packing and shipping. Keep an eye out on the Nova Labs Meetup group for a fulfillment “party” soon!

Thanks again, and we look forward to seeing you around Nova Labs with our fresh furniture and equipment!

Inspirefest 2015 – Family Fringe

Inspirefest is a two day technology conference taking place on 18th-19th of June in the Bord Gáis Energy Theatre. The conference has a strong focus on STEM and diversity. To go along with the conference, there is a host of fringe events taking place in Merrion Square. We are proud to be taking part in the Family Fringe event on 20th of June.

We have joined forces with Intel and Girls Hack Ireland to create Stop the Lights workshop. The workshop will give insights into the basics of using the Intel Galileo, an Arduino-compatible designed right here in Ireland. Participant’s will get their hands on LED’s, buttons and buzzers, to create a traffic light animation.

The workshop is open to all aged between 15 and 17 and is most suitable for participants who have some prior coding experience. Participants are not required to bring their own laptop or materials

  • Date: Saturday June 20th
  • Time: 10am
  • Location: Merrion Square, Dublin 2
  • Duration: 3 hours
  • Places available: 20.
  • Tickets: Free, but prebook.

Apart from our workshop we are also teaming up with Dublin Maker to give people a little taster session ahead of their July event. Dublin Maker is a family friendly showcase of invention, creativity and resourcefulness, and a celebration of the maker movement. The taster session will also feature the Year of Light makers

We will be showing off projects created by our members. They will include the Egg Bot – draw your own images onto eggs, Skull Radio – listen to music without using your ears, Buzzer Game – classic game of keeping a steady hand and Constellation Quilt – stars, electronics both met on a quilt. 

The UN has declared 2015 the International Year of Light to highlight the central role of light has in the modern world from science and technology to nature and culture. The Year of Light makers will demonstrate how light is used in our everyday lives though lots of hands on experiments from making UV bracelets, lenses out of Jelly and LED badges. There will also be some optical illusions to show the different ways in which light works.

Book Club on Hiatus

Thanks to those who made it to book club last Friday. It was especially lovely to catch up with some old members over from Germany! But of late attendance has been low as people are away or busy working away on projects. So, for now, there will be no more book club meetups. But don’t worry, there are still plenty of books out there for you to read. You’ll be fine.
