Artistic PCB Design

2020-Aug-10, Monday 08:48 pm
I attended a workshop at HOPE called 'Artistic PCB Design for Terrified Beginners'. I enjoyed it immensely. There is a lot of information at the wiki page, and the instructional part is on youtube.

You are informed about the different layers that make up a printed circuit board, and how to leave gaps to get certain effects, like exposed copper, and holes in the copper to let light through.

The basic circuit, a four-pin SAO, two LEDs and two resistors intended to be an add-on board, template was provided.

It's a steep learning curve, having to learn to use KiCad, Inkscape, and Krita. Krita is a my new favourite graphics program. It won me over by being able to create vector layers on top of your raster layers.

I wasn't prepared and had to hurriedly find some artwork to play with to make my first board. So I found some artwork of someone I don't think would mind becoming a circuit board. Here's my first attempt using too much halftone.

Now I just have to wait for the surface mount components to arrive to complete the boards.

EMF 2020

2020-Jul-21, Tuesday 12:42 am
EMFcamp should have been this weekend. But like most gatherings this year, it has been cancelled. It only happens every second year, so the next one isn't until 2022. Which feels longer away than it is.

2014 )

2016 )

I found my way back in 2018, posted about my projects; Colour Stealing Underskirt and Colour Stealing+ Cyberpunk Headpiece, but didn't get around to writing about the event itself. So here goes.

2018 )

I think everyone who has been is missing EMFcamp about now. A deep longing in our souls. I'm going to try and focus on some project work, in tribute. Now, go lose yourself in the past talks.

Being at Congress is like living on a multi-generational spaceship. It is large, the scale initially boggling the mind, full of pretty blinky lights, random gases, sculptures, and lasers. With more computer power than I can concretely conceive of. It also contains thousands upon thousands of souls. Of every age, including children, some born into this life, others having found their own way aboard. All squeezed into a confined space. You get used to the grandeur, you get accustomed to the crowds, and how to time your visits to talks, food stalls, toilets. When another group puts on an event, throws up some lights, makes some music, puts up posters, you adapt, you absorb. You fall into the rhythm, you become part of the whole. There forms an expected pattern of thinking, an expected behaviour, even a lingo, in-jokes. Even beyond the usual uniform of tshirts and hoodies, there are the official tshirts and official hoodies. For all the talk of difference and individuality, of doing things your own way, you become just one more member of the hive.

Despite the affectation of being outsiders, aliens stranded, everyone involved are just people. Regular issue humans. Which means they are flawed, they make mistakes, are capable of horrible things, and sometimes outright fuck up. They have the capacity to learn. They are also discrete, there is no homogeneity, there isn't even an united front. It's children, grownups, playing make believe. Because if there is one thing they all might have in common, it is the belief that we can and should be doing more, that there is a better way forward.

So it strikes me as hypocritical that some people become so hostile, like misfiring anti-bodies responding to threats to the system, when fellow members are justifiably criticising (in)actions, challenging status quo, and demanding better from their own community. Something goes wrong, the bug report gets filed. But no adequate fix results. This upsets, causing ever increasing ripples of disharmony. The damage will only grow and spread if nothing is done to fix it.

If the spaceship does continues to atrophy without remedy, if there is nothing left for us to salvage, it is worth reminding ourselves, it's not a multi-generational spaceship. As painful as it might be, we can leave. There is life outside.

Maybe we can even add more ships to the fleet.

LovelaceSpace

2017-Apr-14, Friday 10:54 pm
Ahem. Hi. Yes, I'm still around. (Only four more years of posts to go through and relocate the images, and I'll be LJ free!) I was at MakerFaireUK a couple of weeks ago, helping some of the tog guys at their stand. It's always a great trip, to catch up with people from other spaces. (And this time I even got to drool over a laser cutter I really, really want.) But things were a bit different this time, I was wearing a different hoodie. This year I was representing for LovelaceSpace.

A while back I made a post about why I needed to leave tog. In the meantime, as I whined to anyone who would listen, people started making suggestions, and dropping hints. This coalesced into something. Something truly wonderful. A working group, of passionate, hard-working, truly kick-ass humans, to set up an intersectional feminist lgbtq+ inclusive secular space, for hackers, makers, educators, and feminists, in Dublin, Ireland. It's a massive undertaking, we know we're unlikely to get everything right, but we really, keenly, want to try.

Our first event was last month. A cross-stich event, held in a very congenial pub. We'd expected maybe 20 people, 30 people tops. Turnout was more like 65-75. Some people even dropped in just to pick up kits. We could barely cope with the volume. At the busiest we had taken over more than half the pub!

We can't take all the credit. The event was a charity fundraiser, a rather popular one, and it was just before International Women's Day, and the protests that were planned to coincide. We raised €360, which bowled us over. The money went to ARC, an organisation challenging the restrictive abortion laws in Ireland. They are just one of many groups campaigning for change, to Repeal the 8th Amendment.

Our event idea was simple, take the symbols of these organisations, this iconography of the movement, and create cross-stitch patterns that people could turn into pins/badges/anything they wanted. We just didn't realise it'd be so popular! We had people from the other ends of the country asking us to run the workshop down there too. We had people in England wanting in. The solidarity, the love, in these communities, is so strong, so raw. Especially coming from a mostly techie background, it was a surprise for me. It was beautiful.

Well, our next event is somewhat similar, but completely different. The Science Gallery have a 'Humans Need Not Apply' exhibition on at the moment. They have an AI, Hoopla, that designs embroidery patterns. They've asked us to run a workshop to show people how to turn these designs into actual physical objects. This event is free, but also much smaller. It should be fun.

From the organisational side, we have another meeting tomorrow. We're working on finalising our Code of Conduct, planning even more events, and trying to get our documentation in place so we can become a legal structure. And then, find a physical space so we can house this amazing community 24/7.

It's hard work. For a group of people who are already over-worked. But the need for this kind of space, the passion and dedication of the people we interact with. It's a tonic against so much going wrong all around us. It is my primary source of hope right now.

Congress is an experience. Having an Assembly to hang around is a major plus. Like other conventions, the main purpose seems to be meeting up with people you don't get to see every often. (And complaining about how tired you are.) There were enchanting displays all over the place. I'm sure I didn't even manage to see everything. It never really stopped either. There was dancing in the snowglobe at 6am. There was hanging out in the sci-fi console area of the purpose-built-technically-outside lounge at 7am. I still haven't quite got the hang of the toilet and elevator parties. I wish I'd been well enough to do more, see more. But I certainly have ideas for next time.

33C3; day zero

2016-Dec-26, Monday 10:40 pm
Agent chebe reporting from 33C3; day zero. Although I've been to hacker camps before, like OHM and EMF, this is my first Congress. Plus side; no tents. Negative; hotel is far away, and there's winter rain. We got our wristbands, set up the Assembly next to the lovely Scottish Consulate. Got on the wifi. You know, the essentials. Had a quick look around as people were setting up. It already looks amazing, I'm sure tomorrow will permanently warp my sense of reality. I am a bit worried about how crowded it will be. 13,000 people, one venue. But there is that feel in the air, the one of creative minds working away.

P.S. I am probably Patient Zero.

EMF 2016

2016-Aug-10, Wednesday 10:46 pm
EMF happened last weekend. I went, with some of the tog people, but not with tog. It was a really good weekend.

It's difficult for me to describe what EMF is. Because it is simply too big now. There was somewhere between 1,000 and 1,500 people, camped in one large field. With five stages, several workshop tents, villages, bars, food vendors, and a giant beanbag-filled lounge tent. Every person attending will have had different experiences, some even seeming to be from completely different events. It's large. There's a lot on. And it's utterly surreal.

If you've been to any of the maker faires, then EMF can be described (as one of the other attendees said) as a large faire, only instead of explaining your ideas and projects to regular people you're showing them off to other makers and hackers. There's a level of engagement, of enthusiasm, of sheer energy, that is difficult to gather in other places. It's a bit like a temporary Never Never Land, full of grown-up techie toys, organised and run entirely by volunteers. Large inflated bunny filled with neopixel strips that you can change the colour of by tweeting it. Really tall LED tower game. Pong made physical, with giant paddles and fire. A podium that made fire dance to music beats. Bbqs, fire pits, self tending bar robot. Amazing micropython badges. An incredible wifi network with over 64 access points, a beautiful dashboard, and nearly two terabytes of data transmitted. Electricity to your tent. Hot sunny days, clear starry nights.

Reality is proving just how hard an act EMF is to follow.

You can check out photos, and watch the talks. It will give you a flavour, but it isn't the same as being there.

An aside )

It was a replenishing weekend. Fun, energising, and completely exhausting. I want to go back.
Yesterday (Saturday 20th February) Career Zoo was once again held in the Convention Centre. It had a couple of themes, one of particular interest to myself; women in tech. I wasn't sure what to expect, but the powerhouse that is Coding Grace got in touch, organising a mini wearables hackathon in the middle of the whole thing. Uh, yes!

We spent the day in an indoors white-picket-fenced picnic area next to DAQRI, our generous sponsors. Playing with toys, battling software, sharing resources, talking to curious attendees, and having a great laugh.

SciHackDay side project

2014-Nov-19, Wednesday 09:34 am
Set the scene; it's midnight, I'm just back from (sci-fi) book club, SciHackDay kicks off in the morning, and I want a project; something sciencey. I decide I want a radio telescope. But, well, I don't have the parts. So I scale back my idea into something I can iterate up into a radio telescope.

I shifted my focus on the electro-magnetic spectrum up to visible light, hoping to use my new colour sensor. It will really only give me one reading from one point of space, like a single pixel. To scan an area I'll need something to move it along. But I don't have any servos, and I've never played with motors before. Luckily I have a robot arm handy. And then the rest should just be Arduinos.

That's the thing about poorly researched hacks, they're never as straight-forward as they seem.

Down the rabbit hole )

Also, photos are up!

SciHackDay 2014

2014-Nov-17, Monday 12:47 pm
Science Hack Day is an all-day-all-night hackathon; covering software to hardware, but with a project emphasis on science. It's in its third year running in Dublin, but this is the first one I've been able to attend (November is a much more civilised month than March).

It started Saturday morning (15th Nov), and finished Sunday evening (16th Nov). In thirty-two hours of incredibly intense focus, I got a mere thirty minutes of sleep. But ate a lot of pizza! It was fantastic the way the SciHackDay crew set things up. Large quantities of food would just appear every so often, and there was a steady supply of snacks throughout. Eliminating one very common, and annoying, disruption to work; that of hunting, gathering, preparing food. Sleep as well! Although many people went home to rest, and some managed a few hours on sofas and floors, my brain was just getting settled into focusing on some software work in the wee small hours, and not being forced to leave and miss that period meant I was much more productive than I would have been otherwise. But I am very glad it wasn't any longer. As soon as I got home I fell asleep for sixteen straight hours.

There were some really great project ideas, and even more great project implementations. (A fantastic number of wearables and etextiles too.) But I was wary of the too-many-cooks problem, so I helped out where I wasn't in the way, and worked on my own small project.
