Kickstarter update – 80%+ funded!

Greetings makers!

Just shy of two weeks into our 2015 Kickstarter campaign, we are happy to announce passing 80% toward our goal (86.4% to be exact)! Thanks to everyone who has backed the campaign and shared the link with friends.

Since the campaign is getting very close to passing the $20,000 goal, now’s the time to start teasing our stretch goals!

Stretch Goal #1

One of the big requests at Nova Labs is welding equipment; our new 10,500 square foot facility has a great workshop just waiting for this new capability. Raising an additional $7,000 will allow Nova Labs to acquire the following:

  • Welding table
  • TIG and MIG Welders
  • Safety equipment (gloves, helmets, and shields)
  • Ventilation and welding curtains

There are many Nova Labs members that are ready to teach welding classes, which should allow more people in the community to learn new skills for their projects.

Back us now on Kickstarter, and stay tuned for stretch goal #2!

Kickstarter update – 80%+ funded!

NL member Srijay setup this Raspberry Pi to display our Kickstarter status – he even made it open source and posted the code on GitHub!

Lost Artwork Found!

One of our members Marie made a beautiful painting of Lightning from Final Fantasy XIII.  Sadly when Marie moved away from Philly to pursue her programming career her painting got lost in the abyss that is the Hive76 utility closet.  Luckily her painting resurface and is now on display for everyone to appreciate.

Thank you Marie, we miss you!

Tutorial: Programando Attinys con Arduino

Tarde pero seguro lanzamos el primer tutorial del año. Éste tutorial asume que ya tenés una experiencia básica de electrónica y Arduino pero tampoco es rocket science así que adelante!

PROGRAMANDO ATTINYS CON ARDUINO

Como muchos de ustedes saben, la popularísima plataforma Arduino tiene por cerebro un microcontrolador. Pero qué es un microcontrolador? Segun la Wikipedia, un microcontrolador es un circuito integrado programable capaz de ejecutar las órdenes grabadas en su memoria. Arduino usa el el Atmega328P. Es un chip muy versátil, con puertos de comunicación serial, bastante memoria flash (32k) y varias entradas y salidas (20!). Para muchas cosas, usar un atmega328P es demasiado. Desperdiciamos memoria y pines entre otras cosas. Para hacer tareas sencillas que no demanden muchos pines ni memoria, podemos acudir a la familia de microcontroladores ATTINY85/45/25

Ésta familia de microcontroladores tiene apenas 8 patitas y su memoria flash (el lugar donde se alberga nuestro código) es de 8, 4 o 2 kilobytes (de acuerdo al número en su nombre). Pero para muchas de las cosas que solemos hacer con arduino suele ser suficiente!

Tutorial: Programando Attinys con Arduino

Como verás en el esquema de arriba, tiene dos salidas digitales (ambas permiten usar PWM) y tres entradas analógicas. A que varios de tus proyectos en Arduino no usan más que ésto, no?

Y cómo hacemos para programar estas cucarachitas usando la IDE de Arduino? A la hora de elegir la tarjeta donde programar, tenemos que tener la opción de elegir a nuestros ATTINYs Para ello vamos a necesitar el core que se encuentra en éste link. Sequí las siguientes instrucciones:

  1. Descargá la opción de acuerdo a la IDE que estés usando (ATENCIÓN!: para el tutorial que estás leyendo usamos la IDE 1.0.5. No podemos garantizar que funcione en otra pero es muy probable que sí). Si vas a tu carpeta de descargas vas a encontrar un archivo con el nombre arduino-tiny-varios-numeritos.zip
  2. Descomprimí el .zip. Aparecerá una carpeta con el nombre tiny. Copiá (o cortá) esa carpeta.
  3. Buscá la carpeta en tu disco donde tenés la IDE de arduino (se llama Arduino naturalmente!). Hacé doble click en ella.
  4. Vas a ver que adentro de la carpeta Arduino hay otra que se llama Hardware. Hacé doble click en ella.
  5. Dentro de la carpeta Hardware, pegá la carpeta tiny que habías copiado anteriormente.
  6. Listo! Abrí la IDE de Arduino. Si vas a board o tarjeta, deberías ver un lío de opciones cómo este:
  7. Tutorial: Programando Attinys con ArduinoVas a ver muchas opciones para elegir attinys en diversas configuraciones. Si no apareciern más que las típicas placas de siempre, revisá los pasos. Tal vez no pegaste la carpeta o la pegaste en una ruta equivocada.
  8. La IDE de Arduino ya está lista para programar los attinys. Pero necesitamos un programador hardware tambien!. Nosotros vamos a usar un Arduino como programador. Para eso tenemos que subirle un código especial. Tomá tu placa arduino o arduino-compatible y conectala a tu compu.
  9. En la pestaña Archivo, andá hasta Ejemplos y buscá ArduinoISP:Tutorial: Programando Attinys con Arduino
  10. Subí el sketch a tu placa (damos por sentado que ya sabés cómo elegir la placa y el puerto de comunicación):
  11. Tutorial: Programando Attinys con ArduinoAcabás de convertir a tu arduino en un programador de microcontroladores. Para usarlo como tal, sólo tenés que dar un paso más. Andá a la pestaña Herramientas, luego a Programador y elegí Arduino as ISP:
  12. Tutorial: Programando Attinys con ArduinoPara este ejemplo vamos a usar un Attiny85. Vas a necesitar, además de tu arduino y tu attiny, una protoboard y cables de protoboard. Opcionalemente podés agregar tres leds (uno verde, otro rojo y otro amarillo) y tres resis de 220ohm para tener una respuesta visual de lo que está sucediendo. Conectá todo en la protoboard siguiendo la siguiente imagen o el esquemático (recordá que podés hacer doble click en las imágenes para verlas más grandes):

13. Para testear la comunicación entre arduino y attiny, vamos a usar el clásico ejemplo Blink. Seguí la siguiente ruta para abrir el sketch:

Tutorial: Programando Attinys con Arduino
14. A continuación reemplazá el número de salida digital (13) por el 0 (pata 5):

Tutorial: Programando Attinys con Arduino

 

15. Ahora andá a tarjeta y seleccioná la siguiente opción (attiny85 @ 1Mhz) :

Tutorial: Programando Attinys con Arduino

16. Subí el código al chip apretando el botón Cargar como hiciste en el paso 10. Si colocaste los leds indicadores como te mostramos en el paso 12, deberías ver parpadear el led amarillo, lo que indica que está cargándose el código al attiny.  Cuando veas el cartel de carga terminada, tu attiny está listo! Para ver tu led parpadear, armá el siguiente y elemental circuito (no uses más de 5V!!!) :

17. A esta altura, si todo está OK, deberías ver tu led parpadeando:

Tutorial: Programando Attinys con Arduino

Misión cumplida! Si algo falló en el camino, no te olvides de triple chequear instrucciones y conexiones. Ahora, tal vez te preguntes si vale la pena tanto esfuerzo para hacer lo mismo que hace el 555 a menos de un décimo de su precio! Como respuesta a esa pregunta, esperá el siguiente tutorial (coming soon!!!) donde haremos algo muuucho más interesante con nuestro miniamigo el attiny85.

UPDATE!!! En estos días, descubrimos la maravillosa herramienta online Codebender que te permite programar tu placa arduino-compatible desde tu browser de internet! (Firefox o Chrome). Como tiene soporte para attinys usando el mismo e increíble core que usamos en este ejemplo, podés programar el sketch desde la nube directamente! Abrí una cuenta (gratuita) en codebender (desde el link de invitación que te dejamos antes) y seguí sus (súper fáciles) pasos de configuración. Podés saltarte por completo los pasos 1 al 8, seguir los pasos 9 al 12 y reemplazar el resto de los pasos por este link donde sólo deberás presionar el botón Run on Arduino. En futuros tutoriales seguiremos sacando provecho de Codebender como también de Fritzing así que no dejes de indagar estas herramientas. Seguimos en contacto!

Getting to Kwartzlab: Road Work edition

We’re really looking forward to the new ION light rail coming to Waterloo Region, but being right next to the line means we’re going to have to deal with construction headaches for the next couple years.

As a general rule, we’d say avoid Charles St and take Courtland to Kent St. But right now, Courtland is completely blocked at Benton. So if you’re coming from the south (or east, as Kitchener directions go), you’re better off taking King or Weber to Stirling and getting to Courtland that way.

Here’s a map.

You can also access the Thrift on Kent parking lot from Stirling Ave.

Our Charles St. parking lot has been inaccessible the last few days, so it’s best to plan to park on Kent.

The NASA Space Apps Stuttgart 2015 Hackathon winner BigWhoop is a finalist for the NASA Global People’s Choice Award!

The NASA Space Application Challenge 2015: one hackathon weekend, 133 cities around the world, 949 projects, and our BigWhoop project is among the final 15 for the global People’s Choice Award. Read on to learn what happened during the event at the Stuttgart hackerspace shackspace and then go on and vote for BigWhoop and make it win the award!

NASA’s Space Apps Challenge is an international mass collaboration/hackathon organized on a global scale and held in all major cities worldwide, with a focus on finding solutions to challenges faced in space exploration and also to life on Earth.

The Winner of the Stuttgart chapter of Global NASA Space Apps Challenge is BigWhoop. BigWhoop addresses the “Open Source Air Traffic Tracking” Challenge. This challenge required the building of a tool that allowed users to select a particular flight and see its out-the-window or other views of the aircraft, and airspace. We decided to extend the scope of the project a bit. Our app was designed as a global sensor grid to measure the whole radio spectrum -thus  making air traffic monitoring a subset of the solution. This free and community driven approach based on small and low-cost software defined radio devices earned the local team a global nomination for NASA’s People’s Choice Awards and will be competing to be among the final 15 out of 949 projects for global People’s Choice awards. And now you can vote for the Stuttgart Team as of 27 April.

Just visit this page and vote for our #BigWhoop app (once a day).

 

All this was possible because we started early. We had a kick-off event in February to give people the opportunity to meet, find a challenge to tackle and prepare it before the official Space Apps hackathon weekend during the 10th to 12th April. Having an early launch event was one of the results of our first Space Apps in 2012 and it worked out beautifully. A two day hackathon is great to pitch an idea, but we wanted to show a working project. From sensor nodes that can be deployed at hundreds of locations worldwide to the processed data ready to be analyzed on a map. It also made it possible to include interested people as virtual participants. Three BigWhoop team members come from Bolivia, Poland and the UK respectively and they already knew the goals of the project and provided essential parts to the project via Skype and GitHub. This already made our project feel global and important for everybody. You can still join BigWhoop, just get our code and start using it!

The hackathon was great to knit the team even tighter and add last minute additions.  The support of random people at shackspace was also a big factor. People not even on the team overheard us discussing project details and simply joined ad-hoc and contributed their solution. This lead to the music arrangement you listen to during our video presentation and “node zero”, the very first node of our sensor grid now working on a virtual machine in shackspace’s experimental datacenter is not just producing data but also responsible to collect data from everyone contributing to the grid.

Ultimately BigWhoop is intended to run on the Constellation computation grid with 60,000 computers. However, we started a pre-alpha test. So we asked for your help during the hackathon weekend to plug in your software defined radio devices and start a sensor node for us. Our BigWhoop software was already able to send this to our server at shackspace and we received data from nice people in Virginia, US and Bremen, Germany. With this help, we were able to show you a first live demo at the end of the hackathon. Since then, we received further data and are really overwhelmed by everyone’s support and want to say a big THANK YOU!

One team member took BigWhoop to Observatorio del Teide

 

As a team, we believe in BigWhoop and we will keep on working on it. One team member took a sensor device with him on a measurements campaign of his work and monitored the spectrum on his free time next to the Teide volcano on Tenerife. The scientific paper about the project was selected for the International Astronautical Congress 2015 in Jerusalem and we will present the Space Apps Challenge with “Opportunities of an open-source global sensor network monitoring the radio spectrum for the (new) space community” during the SPACE COMMUNICATIONS AND NAVIGATION SYMPOSIUM. And lastly, BigWhoop will serve as the ground station application for the Distributed Ground Station Network project also related to shackspace. There, it will help us tracking and communicating with small satellites globally and continuously and thus helping the satellite operators to get their positions and payload data faster than other systems.

Concludingly, BigWhoop and the NASA Space Apps Challenge was fun and a great experience. We learned so much during the event, we felt to be part of a global community, work(ed) on solving an important problem and started a project that can become even more than we can currently imagine. We as the local organizer and team will definitely apply for Space Apps Challenge 2016 again and bring it back to Stuttgart for you to tackle new challenges. We hope, that you like our BigWhoop project as much we do and give us your vote during the People’s Choice awards and make it win the space challenge!

Sometimes you gotta think outside the vase!

I found this nice vase on Thingiverse and printed it at 75% scale a couple weeks ago.

75% scale vase looks fine from this angle…

It came out pretty good except for the area near the bottom where it was overhanging.  3D printers don’t handle overhangs without support material very well.  I tried reslicing with support material added, but didn’t like the way it looked in either Cura or Slic3r so I didn’t try to print it again.

Sometimes you gotta think outside the vase!

Overhang caused poor print quality for the first 6-8mm of the vase.

 

Then I tried printing it upside down- the overhang is much smaller.

Sometimes you gotta think outside the vase!

100% scale vase printing upside down.

About 12 hours later, here’s the result:  perfect!

Sometimes you gotta think outside the vase!

The two vases, bottoms up- the 100% scale vase is perfect!
