I like vacuum tubes. Have I mentioned this before?
I have a mental registry of small projects that involve vacuum tubes and one long-standing idea is a Christmas tree ornament. Here's how it goes.
(This involves fire, broken glass, and probably all of the chemical horrors of the 1950s. Say your prayers, wear eye protection, and Don't Be Stupid.)

Ghetto Tablet
This came into FG a number of weeks ago and, like many curios, wandered its way around the mezzanine getting prodded by volunteers. Nobody quite knew what to do with it but nobody was willing to scrap it.
This is probably the closest thing available to a modern tablet computer -- made about a decade ago. I've spent altogether too much time in the last week or two getting it working.

Audiophile silliness, now on a motherboard!
A couple of weeks ago I got hollered over to the dismantle bench -- "you have to see this" or something of the sort. Here's what they had inside the case:
It's the usual mess of wires and junk -- but way at the back, there's something that you will probably never again see on a motherboard.

Happy Binary Day!
It's 11/11/11 (and shortly 11:11:11) -- so happy binary day! This celebration just goes to show that we learned nothing from Y2K and still use two-digit years when it's convenient, but then again, 2011/11/11 just doesn't look quite as pretty.
I'd propose that we keep the powder dry for a real celebration in 2048 -- that's 100000000000 in binary. We won't roll over another digit like that until the year 4096.

Firmware and Bad Ideas
Geoff and Brian came across a strange situation last Thursday and called me over for a look. They were working on building a machine, and were experiencing a very Hallowe'enish phenomenon: a ghost disc.
They had installed an apparently working LG DVD drive into the machine, but every time they closed it without a disc inserted, a phantom disc called "Bluebirds" would show up on the desktop.
At first I thought it might be a PEBKAC -- a friend one listened in embarrassed confusion to most of a Frank Zappa album not realizing that she'd accidentally stuck two discs into the player at once. But to give Geoff and Brian some credit, it was nothing of the sort.

Proxima Desktop Projector 2400
I like old video projectors. They've been around in some form since the dawn of television -- the old CRT-based ones were technically the same as televisions with the brightness cranked so that they'd throw an image onto a screen. These evolved into huge three-tube monstrosities that you can now get for the price of a hernia.
But when the LCD display came along things got more interesting. In the late 80s someone started manufacturing little units that sat on top of a classroom-standard overhead projector. IBM's Thinkpad 755CDV laptop from 1995 could have the back of its display stripped off so that it could be similarly used to project an image.
By the end of the 1990s digital projectors had taken a familiar shape and dropped massively in both weight and price... but in the meantime there were some weird species in circulation. I already wrote about one (see the end of the article). Here's another. Excluse the blurry photography.

The Worst Computer Of All Time
I've slagged a few computers here for being knock-offs or badly designed -- and I got called out by a commenter on that last one, who basically said "hey, I used one and it wasn't that terrible." And I can't disagree with the guy. Our old cadaver powered up dutifully, dead hard drive notwithstanding, and I don't doubt it would run reliably for another quarter-century.
On the other hand, there have been lots of computers sold with much more serious problems -- laptops with exploding batteries, untrustworthy hard drives, defective motherboard capacitors, computers that had to be dropped periodically, and awful quality drivers, not to mention this infamous scam.
All of this makes the maligned Zenith Eazy PC look pretty good. But this got me thinking: what is the worst computer of all time? Everyone loves a good train wreck -- so if you disagree, please submit your own. But my money is on the IBM PCJr.

Commodore C286LT Laptop Teardown
Hi all,
I'm about to disappear to Europe for a couple of weeks (whee!) and will try to visit something interestingly nerdy while I'm there -- the Berlin Computer Game Museum? A small computer museum at Humboldt? But in the meantime, here's a teardown in the oddly fertile vein of 286 laptops.

Cassettepunk MP3 Player: How to do it
Hi all,
Here's a few words on how this hack (the second one, that is) was done. This is a reconstitution of some old notes I made during the process.
This focuses primarily on the software side -- the hardware side can be pieced together from the photographs, aside from the one hardware modification to add a second USB port to the WL-HDD device.
This post contains no pictures and a lot of grisly detail. You have been warned.

Cassettepunk MP3 Player
Hi all,
Time for another hack. I've been doing these for a few years and though they're pretty diverse there are some common threads: one, they often involve music; two, they involve a particular niche of time after something has ceased to be useful but before it's gotten interesting as an antique. Call it "Cassettepunk".

Free Geek 2011 AGM
Hi all,
Free Geek held its 4th formal Annual General Meeting yesterday evening at the Maritime Labour Centre just down the street. In Free Geek fashion we dismantled the orderly rows of chairs, ignored the raised podium and microphones, and sat in a circle. The AGM is the yearly changing of the guard where the old board of directors steps down and a new board is chosen. Here's one quick report on how it went.

Field Trip to the Mothership
Well, it finally happened -- I've been promising myself a trip to Portland for a long time. It's been on my radar for many reasons: it has great live music, a micro-brewery scene bordering on religious fanaticism, and currently plays mecca for cycling culture, urban experimentalism, and more. I'd like to think it's Vancouver's cooler, laid-back older sister -- and a vision of what Vancouver could be if it were just a little more relaxed and a lot more affordable. But my main reason for visiting Portland was to tour the Free Geek Mothership -- the place where it all began.

Geeks and Knitting
Somehow knitting is suddenly subversive and cool -- from yarnbombing to knitted zombies to sock wars it screams of a previously-uncool niche suddenly discovered and embraced. But there is something irredeemably nerdy about it. I chatted with one of our volunteers -- also a knitter -- about this and discovered a few odd parallels.

Bylaw success!
Last night's Extraordinary General Meeting (back-story here) was attended by a little under 20 people -- the current directors and a staff member or two, but as it should be, mostly volunteers.
After a brief bit of discussion and some easy comedy at the expense of Robert's Rules, the motion to amend the bylaws was tabled and passed unanimously.

On Power Switches (Part 2)
I wrote about power switches here and was working up to some broader numbers that take the discussion out of the individual household and into the greater infrastructural realm. Each household has a few things kicking around that are always on, or can only pretend to be turned off, and the cost is a handful of watts -- who cares, really? Well try multiplying that by millions of households and the costs mount up.

Mystery Laptop
I wrote here about the difficulties laptop manufacturers had in the late 1980s combining hard drives and battery power, and made the suspect statement that the Macintosh Portable in 1989 was one of the first to feature both.
I might have found a better contender. It's definitely a strange one:

Old Gear Lives On: A Hack (Part 2)
Hi all,
I've wanted to document the technical side of some hardware hacking for quite a while. Here it is, continuing from the less-nerdy first part.
The project: Turn a 286-based Compaq Portable III into something more modern.
The motivation: to be honest, my sole motivation here was to be able to haul it down to Cafe Prado, a thou-shalt-be-at-least-this-hipster-to-enter coffee shop on Commercial. Nobody's allowed in without at least a Macbook Pro and I wanted to plunk this beast down on a reinforced surface and see what happened.

A moment of sympathy for the user
This Thursday one of the staff members asked me to help a customer who had purchased a laptop several weeks prior and was having ongoing difficulties with his wireless card. The customer eventually arrived on a bicycle, bearing the offending device. He seemed to be naturally pretty tightly wired, and having spent the previous evening attending Windowless Wednesdays only to encounter another problem shortly thereafter, his patience was strained.

Technological Atavism
Sometime in the early 1990s I came into possession of a Wang word processor -- one of the ones with 8" floppy drives. I tried to find out about that particular model, but quickly learned that you have to be careful how you search for pictures given this subject matter.
My favourite things at Free Geek are the technological neanderthals -- the also-rans and could-have-beens. I've posted numerous times about obsolete laptop teardowns and the strange shapes that portable computers tried out before the bog standard laptop emerged. (And who knows how long that'll last -- personally I'm not sold on the idea of tablet computing just yet, but who knows.)
A strange one came into Free Geek over the last week.
In the words of Alan Jackson (ugh) -- what's so crazy about that?

New & Busted vs. Old & Boring
A cynic would say that almost everything that's donated to Free Geek can be broken into two categories: New & Busted, or Old & Boring. Meaning that if something really shiny comes in, chances are good that it won't work.
This used to be pretty shiny and now it pretty certainly doesn't work. We will never know what events befell this computer before it got to Free Geek. Hard drive failure leads to lost thesis leads to anger management crisis? Fell off a desk and under a truck? Placed too close to an MRI machine?

Dinosaurs and Cockroaches
This was going to be a New Years' post, but since it's almost February, I think I'll give up singing Auld Lang Syne and go instead with an evolutionary metaphor.
The equipment we receive as donations at Free Geek spans around 30 years. That covers a lot of revolutionary change, from the advent of the home computer itself, to the explosion of the IBM PC format whose heritage dominates the equipment that we deal with, to the Internet age, through to the increasing domination of wireless and portable computing. And a thousand smaller revolutions in between.
Sometimes it's interesting to note what hasn't changed in all that time. And sorry, folks: I realize that this is going to be a really nerdy post.

Laptop Station Chaos
I spent a Thursday working at the laptop station in the Mezzanine and I suppose it's no surprise to anyone that it's a mess.
In the interests of constructive criticism, consider this not so much an indictment of the laptop station as a celebration of how far the rest of Free Geek has managed to organize itself. Anyone remember what it was like a few years ago, when we first moved into the new space? Or further back, when we were in the old space near Science World? My memory is fuzzy going any further back than my last cup of tea [currently approx. 15 minutes], but I remember that waves of junk swept over every horizontal surface as though deposited by the tide twice a day, only to be fought back by diligent volunteers just in time for the next onslaught.
Both the Mezzanine and the Warehouse have been looking consistently sane, and the store is no longer a knee-deep snarl of wires. And I'm not making light of the amount of work that this takes: Free Geek takes such a bizarre assortment of equipment that there can't possibly be a proper place for everything. It can only be kept clean (in my opinion) by constantly paying attention to all the little corners where stuff can collect. So let me begin by saying: congratulations to all involved for apparently taming the lion.
The laptop station is a bit of a sore spot in the middle of all of this...
OK, it's not the laptop station, but this would make a great tombstone. Whoever wrote this note, you're awesome. |

Thursday's Mystery Device
Last Thursday there was a bit of a disturbance at the Receiving desk -- a batch of old equipment arrived in boxes, and one of the boxes turned out to have a dead mouse in it. (The meaty kind.)
The box also contained this:
At first glance, this appears to be an ancient scanner, filthy and discolored from exposure to sunlight. When it failed to actually be a scanner (i.e. there was nowhere to stick paper into it), I rescued it for further investigation. This turned into a really fun teardown.
The box also contained this:

Network Device Testing Redux; Open Source & Volunteering
Last week I bemoaned the state of Network Device Testing. Here's how it looked one week later:
In summary, not bad, not great. It looks as though motherboard testing has partially migrated to the right-hand side of the desk, and a limited amount of junk accumulated again.
I spent most of the day working with a volunteer on Network Device Testing, teaching him how the station works and talking about volunteering, software development and the open source world. He is interested in studying software or hardware engineering and wanted to know about the prospects for both in Vancouver.
