Building Works Update

We have been transforming our new space over the last 6 weeks. We now have walls o/ . Our plan is split over a number of phases, to start off with we are building rooms 1, 2, 3 and a kitchen as outlined in the drawing below.  Room 1 will be our new common room. This will be the most used room in the whole space and the centre of everything. Room 2 will be our new classroom. It will be bookable for special events and courses. Room 3 will be our fabrication room. It will hold things like our laser cutter , 3D printers and so on. Our kitchen will be at the front of the building getting natural light for enjoying a cup of tea.

We have now reopened to the public with our regular group nights, so drop by and check out our new space.

HACK42 GAAT VERHUIZEN!!!one!1!!

HACK42 GAAT VERHUIZEN! Over een paar maanden, dus er is eigenlijk niets aan de hand. We hebben, voorlopig, nog geen whaaah-alles-gaat-fout-hulp nodig, wil je desondanks weer eens een keertje langskomen: weescht welkom!

We gaan de wereldschokkende afstand van 2 kilometer verhuizen, naar dit awesome pand: het bureelgebouw, Vrijland, in Arnhem. Daar huren we dan de 1ste en 2e verdieping. Waarom? Omdat het kan!

Hoe? Er is een lift, dus we kunnen tijdens de verhuizing onze ruggen en het trappenhuis ontzien. De planning is nu om het huidige pand op te ruimen, het nieuwe pand te verbouwen en in te richten, dan echt alles in te pakken en ergens in maart 2016 de Grote Verhuizing uit te voeren. Zoveel mogelijk in rolcontainers, de rest op wieltjes en vooral alles duidelijk gelabeld waar in het nieuwe pand het heen moet. Natuurlijk gaan we die dag dan ook gepast feestelijk afsluiten. Tegen die tijd zal er nog een uitnodiging volgen, maar houdt er vast rekening mee dat je welkom bent om tegen een rolcontainer aan te duwen.

Ben je nou heel erg benieuwd naar het nieuwe pand, de komende weken gaan we regelmatig wat opruimen en klussen. Voel je vrij om ook te komen helpen en het pand te bekijken: kijk op onze wiki om te zien wanneer. De toegang tot het pand is nu nog beperkt, dus als je langskomt is het handig om dit eerst even door te geven.

Building Our New Common Room

On Friday, a big pile of timber arrived on our loading bay. On Saturday we turned it into our common room. Well we are a maker space after all!

We built sections on the floor and lifted them into position. If you remember our common room from Chancery Lane…….. well this room will be bigger and warmer too. We’ll be finishing it off over the next week or two and building some other rooms. Pics here.

18 december: Lezing “Identity Management” met Bart Jacobs


Is er een probleem met de beveiliging van computers? Worden er bankpassen geskimmed? De privacy geschonden door afluisterbare chips? Is de anonimiteit van het stemmen op politieke partijen in het geding? Dan wordt Bart Jacobs door de media gebeld voor deskundig commentaar. En door de politiek om te worden bijgepraat.

Bart Jacobs is hoogleraar computerbeveiliging aan de Radboud Universiteit Nijmegen en maakt zich al meer dan tien jaar sterk voor de bescherming van het digitale leven van de Nederlander.

Op vrijdag 18 december komt hij (op zijn manier) praten over Identity Management. Omdat het kan, maar ook omdat het belangrijk is. Waarom kun je hier lezen.

Iedereen is deze avond welkom te komen luisteren en kritische vragen te stellen. Aanmelden is niet nodig, maar wordt wel op prijs gesteld. Je kunt je aanmelden via het webformulier op deze pagina.

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!

Epson Stylus Pro 9500 large form printer

We, at tog, like to extend the usability of items for as long as possible. (Or at least that is our excuse for all the out-of-date tech laying about.) So back in May of last year when we were offered a very large format printer, it was hard to say no. (Stay with me sewists.)

Some members took it in, gave it some TLC, and we even found a roll of paper at ReCreate! But then we hit a problem. The last available drivers for it are Windows XP 32-bit. Which is not exactly commonplace anymore.

Then, a short while, and some internet searching, ago, we discovered that gutenprint-cups, the default printing facility on many linux distros actually supports this printer! It’s not hard to install; plug in the USB cable, open a browser, go to http://localhost:631/ and press the right buttons. Done.

Long story short; the printer lives again! And for you sewists out there; ever buy a digital pattern and have to spend hours taping together A4 sheets? Well, if you can also get a large form pattern, you won’t have to do that anymore! Just visit tog some Craft Night and we’ll sort you out!

Metal Lathe

Late last year TOG took delivery of a new toy…. a brand new metal lathe. At about 600Kg, it’s probably the heaviest bit of equipment that we have in the space. We had some fun getting it in the door……and yes we did measure the door before we ordered it Metal Lathe . A bit of heaving and ho’ing with an engine crane and we soon had it up on its cabinet stands. We spent a few weeks assembling it, reviewing all the accessories and getting it all tested. We have 3 and 4 jaw chucks, live and dead centres, steady rests and a number of other tools and accessories.

We’ve had some great instruction from one of our members relatives. We’re now slowly beginning to use it. Our crafters kindly made a nice protective cover from some spare vinyl. The lathe is a great addition to our workshop . We have a brand new MIG welder on the way too, thanks to one of our regular workshop user/members.  We even have a CNC Mill in our sights too….right Ed Metal Lathe .  Drop in and have a tour of our workshop. You can see all of our tools and equipment. More pics here…..Lathe Pics

 

There’s a 3D printer on the ISS thanks to Made in Space and Mike Chen

Humanity reached a big milestone this year. For millions of years, every tool that homo sapiens has ever made has had one thing in common: it was made on Earth.

The first 3D printer in space from Made in Space

But this year we successfully launched a 3D printer into space, marking the first time in human history that we can make an object off the surface of the earth. The group that has made this possible (besides NASA) is Made in Space, a company founded to prove that off-world additive manufacturing is both possible and the next step in space colonization. I talked with Made in Space co-founder Mike Chen about the future of making in space.

Getting to space is getting easier each year, but even with the new SpaceX Dragon missions, the cost of putting a kilogram of mass on the International Space Station is still about US$22,000. That makes it unreachable for most of us. In 2010 Made in Space saw a chance to disrupt this rocket-powered supply chain and enable manufacturing in space using newly available consumer 3D printer technology. They ran countless tests of existing consumer 3D printers onboard a reduced gravity aircraft (aka the Vomit Comet) to find a suitable design. Mike explained the problem, “We actually get a few emails a week [where] someone takes a printer and turns it upside down or sideways and says, ‘See? This prints upside down, so why wouldn’t this printer work in space?’ You know, you’re just not really thinking it through. Gravity is still there, acting as a force to hold things in place.” Remove that force and everything starts to oscillate. Also, heating elements in microgravity are difficult because there is no natural convection to circulate hot air, making passive cooling nearly impossible. The machine also needs to withstand the violence of launch, which may be the biggest build challenge. The Made in Space team decided that they needed a design of their own.

Mike says that’s one of the reasons the space stations exists, to experiment with how different systems act in micro-gravity. This is very much an experiment and is being treated as such. On November 17th, the printer was installed in the Microgravity Science Glovebox (MSG), a facility on the ISS dedicated to possibly harmful experiments, and a perfect place to safely test new technologies. Now that the machine is ready, the first extraterrestrial manufacturing will commence soon.

I pressed Mike for some details on the machine itself. It’s a Material Extrusion machine like most consumer 3D printers on the market. That means it’s full of steppers; everyone loves steppers. In order to limit their unknown variables, they decided to use ABS plastic as their material. It’s one of the most well known polymers and is a very useful material. ABS does have toxic offgassing, so in addition to being housed in the MSG, there are environmental filters to protect the astronauts’ precious atmosphere. A 3D printing professional will also appreciate these simple design guidelines presented by Future Engineers who host a challenge to inspire schoolkids to design an object to be printed in space. Those guidelines also call out the build volume of 5cm x 10cm x 5cm and specific design hazards posed to an astronaut. Printed parts must not have any support structures or require post processing, which could release small particles in the air that can get in everything, including the astronauts. The standard 45° overhang is present as well. Maybe the next machine will be a 5 axis robot that can follow clever 3D toolpaths and truly print any geometry.

This machine has been designed with multiple design constraints to contend with. These constraints really drove Made in Space to develop their own machine and IP. On the ISS, an hour of an astronaut’s precious time will cost about $50,000. That means no fiddling with extruder tensions or babysitting the machine as it prints. So the printer only has one button, the ON button. Everything else is handled from ground control thanks to the MSG’s video cameras.

The big question is, what will they print first? Made in Space is being very secretive about this, but we won’t have to wait long to find out. The first print will be a special milestone, but subsequent prints will be test coupons that can be compared to prints made in an identical machine on terra firma. After proving the printer’s quality, there is a long list of useful objects that are needed on the ISS. There are hundreds of replacement parts already in storage on the station, but in the future those parts will be made on demand. At that point each kilo of printer material becomes a lot more valuable and versatile. There is even new opportunities to improve the lives of the astronauts by allowing family members to send digital gifts into orbit. In 2009 Randy Bresnik’s daughter was born while he was on an ISS mission. Imagine in addition to a photograph, Randy holding a 3D print of the newest Bresnik while passing out bubblegum cigars to his fellow astronauts.

You too can design something to be produced in space. Mike was keen on energizing the thousands of brand new 3D designers in the world to help solve problems in space. This machine gives an amazing amount of access to the 3D printing community on Earth. Made in Space is very receptive to ideas about what should be manufactured in space. Reach out and find a novel solution to a unique problem and there may even be a commercial benefit in it for you. See what Made in Space is doing on their website and follow Mike Chen on twitter: @MikeChen. These are exciting days.
