GAMELÍN!

Finalmente, luego de realizarse en México y Colombia, el taller de Gamelines (dispositivos sonoros diseñados por el Labo de Juguete) se hace por primera vez en Buenos Aires, Argentina. Qué es un Gamelín? Es un circuito sonoro que ejecuta un versión de un escala musical indonesia, mediante la interacción del usuario directamente sobre la placa del circuito. De acuerdo al contacto físico del usuario, el circuito ejecutará una frecuencia determinada (a mayor cantidad de superficie de contacto, más alto el tono). Al pertenecer todas las notas a una misma escala musical, este circuito es ideal para ser ejecutado junto a otros iguales, logrando interesantes climas y contrapuntos.

Gamelín está basado en el uso del microcontrolador attiny45/85  , de tamaño y nombre pequeño pero con grandes posibilidades creativas. Durante una jornada súper-intensiva ensamblaremos y pondremos en marcha 15 nuevos gamelines. A continuación, la información del taller:

Basic Arduino–Learn About Arduino!

You can learn Arduino one of two ways:

  1. Come to the Arduino Special Interest Group on Thursdays, click here for more info, and do a self-paced study course over several weeks. We can provide you with all the items you need, coaching, patience and assistance with Adafruit’s online tutorial.
  2. Email us at email classes@mauimakers.com and let us know that you’re interested. We will set up a special, focused beginner-friendly session to get you on your way quickly.

What is an Arduino?

Arduinos are a low cost, easy to use family of microcontrollers.  Want to learn about the basic use of Arduino computers?

This “week” in Maui Makers 12-7-2015

Lots of exciting happenings at the Makerspace in the last month.

We are trying out a new look to the website. Let us know what you think. If you like the old one, you can find it here.

QuillingClassProject-1024x1024

As part of our Crafty Makers series, Rob Bartlett led an awesome 3-part introductory class on the Zen of Quilling. It’s a great way to make very complex and wonderful objects using very simple techniques.

3D Printing Special Interest Group completed some more of the prosthetic hands, and started an Intro to Fusion 360 self-paced study group.

 

 

20151111_Menehune Makers

We kicked off our Menehune Makers program for younger kids (K-12). Some of the kids are calling it the Robot Class. We haven’t built any robots yet, but will soon.

We continue to have awesome and interesting people drop into the space, and it’s the people who make the Makerspace.

 

 

 

In December, we’ll be focusing on CNC Machines.

Island Hobbies made a generous loan of a 3-axis CNC machine. The terms of the loan were that we take care of the machine and teach folks how to use the machine. We’ll need your help with getting this set up and running. It’s a nice machine that can mill wood, brass, aluminum and steel.

Other activities will continue as usual:

STAR TREK DOOR Continues

So, the STAR TREK DOOR has been a slow, “back-burner” project for a while. Recently, I got a little time, so I sat down and figured out how to hook up the air valves to a set of relays, and control those relays with an Arduino.

Here’s a video overview of the physical doors themselves and how we plan to open and close them with air valves.

This is a joint project, working on this with my brother-in-law, Fred. The doors are between his garage and workshop. Fred has been working on the doors themselves, the wall and framing, and mechanical connections. I’ve been working on figuring out the software, controls, and electronic magic that will drive everything.

STAR TREK DOOR ContinuesThe physical doors themselves are done, except for paint. Fred has also been making a pretty neat frame for the garage side. He cut alternating widths of wood and then glued them together for the nice light-colored wood on the inset of the planks that will frame out either side of the door. A similar piece will cross the top of the door.

I got all the main components – Arduino, breadboard, relay board, 12V power fuse panel, and air valves themselves all screwed to a piece of plywood. At this point, it’s not pretty, but it is functional.

STAR TREK DOOR ContinuesWe have a nice industrial door control with OPEN/CLOSE/STOP buttons on it. Those are momentary on buttons, but through the power of the Arduino, I can make them be whatever I want. I started with a Button Tutorial, and then modified it to suit my purposes, and added a Delay(1500) command after activating the air valve. That way, the valve will stay open long enough to fully open or close the door, even if the button is just pressed for a moment.

I programmed the pin for the STOP button to test out a sequence to open the door, pause (long enough for a person to walk though,) and then close the door. It seemed to work pretty well. If the timing is wrong for the real-world application, all I have to do is simply change the delay times. (It will also need a safety. We don’t want the door closing on a person!)

STAR TREK DOOR ContinuesAt this point, the basics of the control panel are working. The STOP button is just wired up as a “stand-in” for a single button we already have installed on the garage side of the door. It’s a capacitive touch button that lights up either blue or white with internal LEDs. It’s a neat looking button, but it’s only a SINGLE button. So, it needs to have functionality to both open AND close the door. I’d also like to explore using a variable in the Arduino that states whether or not the door is open, and then changes the functionality of that button based on whether the door is open or not. The air cylinders themselves also have built-in position sensors, which would be neat to use possibly as both a safety AND a “Is the door open or not?” sensor.

Here’s a video clip showing all the components actually working together. At this point, if the panel was simply mounted above the door, and air connected between the compressor and air cylinders, we would actually have functioning doors.

STAR TREK DOOR ContinuesI don’t like the look of how the air valves and tees are held together right now. I was able to find some not-too-expensive push connectors (similar to PEX Sharkbite style) for air, which might make it a little easier to connect all the air components and look cleaner. Once I really have everything finalized on what’s going on at the breadboard, I also need to decide if I want to pull the breadboard out and replace it with a custom circuit  board. One thing I DO need is a simple way to connect the tiny pin connectors to the larger wires going to the buttons AND provide strain relief. For the moment, I just used staples to nail the 18 ga lamp cord wire to the plywood and then made the electric connection with alligator clips. What would be the BEST/CLEANEST way to do this? Some sort of small screw down terminals?

I also have a rather large fuse panel mounted on the plywood. It was free, and I already had it. It supports many separate circuits, but for this project, a single DC fuse would probably be fine. I’m also using a bit of an overkill 12V power supply. I’ll want to replace that with a simple wall-wart. Lastly, the Arduino is running from USB power. I’ll need to solder up a 12V DC barrel connector so that it can run off the same power as everything else. I think we will make a switched electric outlet, and plug the wall-wart in to that. If the system is ever not working right, just switch off the power and manually open and close the door as needed.

I’ll definitely want to hang out with the guys at the Makerspace sometime soon talking Arduino, specifically how to integrate some more sensors and get feedback used to activate the doors fully automatically.

Arduino Special Interest Group

Thursdays from 6:00 to 9:00 pm

The Arduino SIG meets to talk about arduinos and other small microcontrollers. Arduinos are a low cost, easy to use family of microcontrollers. We have been teaching classes on using them for several years.  Now its time for the community to have its own Special Interest Group (SIG).

Come down and share your Arduino projects and ideas!   Want to learn about the basic use of Arduino computers?  We will be reorganizing an introductory class to a once-a-month schedule as interest demands.  Want to learn more advanced techniques?  Come down and talk story with fellow arduino users.  Chances are there is someone who has already done something similar or is also interested in learning. Bring your project or project ideas. Come learn and share. If you don’t know Arduinos, you can find out basics and sign up for an introductory class.

Komende activiteiten: decembereditie

Het wordt weer vroeger donker en buiten wordt het kouder. Hoog tijd om binnen met een kop warme chocolademelk bij de kachel te kruipen, ambachtelijke soep te eten en… een spellenavond te doen! Lekker ouderwets analoog. Bordspellen, kaartspellen, waar jij maar zin in hebt! Hierbij kun je denken aan RoboRally, Munchkin, Carcasonne, Tsuro, Mens-Erger-Je-Niet, Lord of the Fries, Masquerade, Kakkerlakkenpoker, etc etc. Heb je ook zin om te komen vrijdagavond 4 december? Dan kun je je aanmelden via deze doodle. Natuurlijk kun je ook spontaan besluiten langs te komen, maar als je ook graag mee wilt eten is aanmelden wel zo handig.

Kom langs met al je Linuxvragen
Ben je net begonnen met Linux, of nog niet eens, maar wel nieuwsgierig? Of droom je in command lines? Een kruk of een crack… het maakt niet uit, op deze maandelijkse inloopavond kun je alle kanten op. Moem en Stoneshop beantwoorden op vrijdagavond 11 december al jouw Linuxvragen op ieder niveau en helpen je om zelf verder te komen. Ook niet-deelnemers zijn welkom!

Arduino workshop
Arduwattes? Dat heeft Witchdoc uitgebreid uitgelegd op de Arduino Workshop wikipagina.

De doelgroep van deze workshop is de absolute beginner, een beetje ervaring met electronica of programmeren is wel handig. Wil je je kennis ophalen of ben je wel aan de Arduino begonnen maar denk je dat een workshop als deze je verder kan helpen dan ben je uiteraard ook welkom.

Bij de workshop wordt gebruik gemaakt van een uitgebreide Arduino starterkit. De kosten hiervan zijn € 42,-. Deze materialen worden natuurlijk jou eigendom. Mocht je zelf al over een arduino met breadboard beschikken dan kan je die natuurlijk meebrengen. Heb je zelf deze onderdelen al dan is de aanschaf van de starterkit niet noodzakelijk. Vermeld bij inschrijving s.v.p. of je een starterkit af zult nemen.

Omdat de Arduino’s besteld moeten worden kan tot uiterlijk 5 December ingeschreven worden, bij inschrijving gaarne ook meteen betalen. Niet-deelnemers (van de space) ontvangen een mailtje van de organisator omtrent betalingswijzen. Er is plaats voor maximaal 12 deelnemers.

Je kunt je voor deze workshop inschrijven via de Arduino Workshop wikipagina.

Maar ik kan die data niet.
Ben je nieuwsgierig geworden naar Hack42 maar kun je op geen van deze avonden aanwezig zijn? Houd dan de agenda in de gaten voor overige activiteiten. Of neem contact op per mail of irc!

Special Event–Calling All Audiophiles

Thursday, November 12, 2015 at Maui Makers 6 to 9 PM

200 Waiehu Beach Rd, Upstairs

Steve Griffin from Boeing has offered to preview his class on using the SigmaDSP board.

This class has several interesting aspects:

A group tutorial setting up a noise canceling system to eliminate background noise. This is similar to the system used in expensive noise canceling headphones. It can also be used to reduce noise in building ventilation systems.

The Sigma DSP board here. This cute little board is specially built for audio processing and can be used to optimize your soundscape and compensate for noise or limitations of your equipment and environment.

A tutorial on Sigma Studio, a graphical programming environment that is used to program this board. It can also be used to program SHARC processors.

Learn Arduino at Makers Local 256 Public Night!

This coming Tuesday (Nov 3) at 7:00 PM, we have some amazing people from YourDuino.com coming by Makers Local 256 to give a presentation/demo/Q&A on Arduino microcontrollers and embedded electronics in general. They’re touring around the Southeast and ML256 is one of the many places they chose to stop by!

Their main objective is to talk to people about Arduino and what you can do with it. They’ll have some kits and parts available during and after the presentation, so if you don’t have an Arduino (or two) already, you can pick one up then. They’ll be showing off a neat display of a few different Arduino projects and circuits, so it should be interesting and fun!

They’ll be going through the entire process of designing, connecting, and coding up a simple Arduino project from start to finish. If you have any questions about your own project, they would love to discuss ideas and give help where they can.

There’s no cost to attend the presentation, but they will have parts available for sale if you need them. Anyone is welcome to attend!
