Agit P.O.V. en Buenos Aires

El labo tiene una visita de lujo en junio de la mano de AgitPOV

Agit P.O.V. (Petit Objet de Vélo) es un microhack para bicicletas inspirado en el efecto de persistencia de visión (en inglés POV), las tácticas de la propaganda de la vanguardia rusa Agit Prop y el proyecto SpokePOV de Limor Fried (Ladyada). Un circuito con leds, un microcontrolador, códigos de programación, una batería y la velocidad de los ciclistas son suficientes para iluminar las calles con mensajes poético-políticos. Agit P.O.V. invita a un taller y un performance textual en las calles, nuestras bicicletas son vehículos que pueden llevar voz poética, creativa y
agitar la ciudad. Este proyecto nace en la primavera del 2012 y reúne a un colectivo de artistas de diferentes latitudes principalmente entre Cali y Montreal promoviendo el espíritu de la cultura libre y la creación digital y
electrónica para las artes. Desde el 2012 ha estado presente en ciudades como Ginebra, México DF, Montréal, Québec,
Túnez, Cali, Manizales, Sackville, Ottawa, Bruselas y Toronto.

Integrantes:
Mariangela Aponte Núñez – Cali
Alexandre Castonguay – Montreal
Thomas Ouellet Fredericks – Montreal
Daniel Felipe Valencia – Cali
Sofian Audry – Montreal

AgitPov llega al labo a realizar un taller de dos días para construir su versión Coyote:

Pixelmatrix

Een van de voordelen lid zijn van een hackerspace is dat er de mogelijkheid bestaat om projecten te maken door TkkrLab worden gesponsord. Zo hebben onze leden Michiel en Robert met een Raspberry Pi B+ 2 een pixelmatrix gemaakt die heel flexibel aan te sturen is, o.a. bijvoorbeeld voor een spelletje pong of net zo makkelijk een plasma effect. Dit project is al gedemonstreerd in het Rijksmuseum Twente gestaan tijdens de Overkill festival, heeft meegedaan met BYOB bij TETEM Kunstruimte en is meegegaan tijdens de eth0 winter editie.

Next time you visit NYC Resistor, you might notice a new LED clock above the laser room door. It’s built with a surplus AMD1026 one-line LED display that has been re-brained with a SparkCore. Eventually we might take advantage of it being online to interface with the laser reservation system. For more details on interfacing with the hardware and the source code, check out trmm.net/SparkSign.

December 6, 2014 Class: Programming 101 with Arduino and LEDs

What
Learn the basics of programming AND a bit about Arduino AND feel the dopamine rush of making electric rainbow colored fire light!

We’ll be using the same kind of lights that are in one panel of our giant wall of LEDs. That’s 64 LEDs. If you already have the LEDs and power supply from our group buy then you can attend for free.

When
December 6, 2014 (Saturday) @ 13:00. See your job for registration deadline.

Who
Anyone! You? YOU. Max 10 people.

Where
VHS main room

How
…much: $75 for the LEDs + power supply you get to keep! $30 Arduino UNOs are available from the vending machine.
If you already have the LEDs and power supply from our group buy then you can attend for free.

…long: 2-3h, based on interest.

Your job
RSVP to this thread so people can count how many spaces are left.
Register on or before November 12, 2014.
Contact Dan through https://www.marginallyclever.com to pay for the parts and complete your registration. If you already have all the parts, you can attend for free.

You must provide your own laptop and a USB A to B cable.

LED Bonanza at the LED Build Day

Ever wanted to play with LED lights? Now you can on our LED Build Day.

Thanks to Instructables, we have a huge collection of 10mm LEDs in a variety of colours, and we’re having an LED Build Day to make everything bright and shining.

From 11am until 5pm on Sunday 17 August, we’ll be working on everything from grand projects to small projects to existing projects, adding LEDs where we think they’ll be best.

If you’re never worked with LEDs, or if you’ve decked out your house in them, you’ll find something at your level of expertise for LED fun.

This event is free, and fun for all ages!

LED Wall of awesome nearly funded!

by Dan Royer

Several weeks ago our wonderful wall of LEDs returned to it’s Burning Man owners. It was 10×42 pixels and loved by all.

To replace it I’m running my third VHS funding drive. (The first was an 3D printer filament group buy, the second was the group quadcopter buy with Jon G.)

Every $30 will pay for one 8×8 panel of LEDs and a power supply. Just like the old wall it will be totally programmable through the Raspberry Pi. When the parts arrive I will host a group build party for all donors at VHS. Come decorate and assemble your panel in an afternoon of fun. Rainbows everywhere!

See two new panels

I’m also accepting $60 order of one-for-vhs-and-one-for-you. Take what you learn home and apply it to your next project. Burning Man? BITF? Bike Rave? Work less party? Halloween? So many good reasons! Please make clear this is what you want or I will assume you are donating two panels.

Minimum Goal

The minimum goal is to get 6×2 panels ($360) for a new wall that’s 48×16 LEDs.
Achieved 2014-07-08

Stretch Goals

If we get more donors than needed we’ll put the pixels closer together for a more detailed picture.
6×3 panels ($540)
12×2 panels ($720)
12×3 panels ($1080)
12×4 panels ($1440)
etc…

Donate Before…

This funding drive will end 2014-07-21.

Send your donation via Paypal to dan at marginallyclever dot com, or cash/credit card in person at VHS on Tuesdays from 20:00 to 22:00.

Emma-Ohnoes

Emma-O judges your cloud infrastructure.

Every now and then, a particularly hard storm hits an undisclosed datacenter in Virginia where a huge chunk of The Cloud faces off with actual clouds to see which one can keep electricity running through it the longest. Sometimes the data center loses, causing DevOps teams and assorted other developers to get calls and tweets from literally everyone telling them their site is down.

Usually this sort of apocalypse is indicated with a tiny icon on a web dashboard, visible only to the people already panicking and frantically reading up on High Availability and Multi-AZ Deployments. A little red icon doesn’t quite convey the gravity of the sky falling, so I figured the best indicator of cloud infrastructure status would be the Buddhist king and judge of hell, Emma-O (aka Enma-O aka Yama). I happened to have a scan of an Emma-O wood sculpture from a previous project at the museum I work at (btw we’re hiring), so I scaled it up a bit and printed a copy in transparent blue-ish PLA.

Emma-Ohnoes    Emma-Ohnoes    Emma-Ohnoes    Emma-Ohnoes

A box I quickly whipped up in Tinkercad for the electronics sits under a lid connected to a replica of Emma-O, Emma-Ohnoes, to his throne with some glue. Housing an Arduino Yún with a sketch using Temboo, it checks on our custom system health check page to see if the AWSpocalypse has begun. If it has, Emma pulses a vengeful red light. Otherwise, he glows a serene blue.

Emma-Ohnoes

All’s well in the world.

Emma-Ohnoes

The cloud is stormy tonight.

If you enjoy using Muromachi-era Buddhist art to let the office know the site’s down, the 3D models for Emma-O, the also-3D-printed base, schematics, and Arduino sketch are freely available online. The Arduino sketch is designed so that any URL you want to set targetUrl to only needs to return anything other than 200 OK in the HTTP response header, so it can also be pointed to the URL of a site directly to see if it’s up or not.
