You may still be able to get surplus Sayso Globord programmable LED signs in surplus stores. It’s a 7×24 LED scrolling sign that you can program with a lightpen or with audio input.
The unit comes with no software, but has a link to https://www.dropbox.com/sh/q1q9yhahwtblb23/AACpMeXQjYyD8ZWC-65vNgcxa printed on the box. It’s an archive of the programming software, manual, and canned audio files for a whole bunch of standard messages. Here’s an archive if the dropbox link goes away: SaySo.zip
The audio files used for programming the display are clearly FSK-encoded, but I haven’t quite worked out the relationship between the tones and the display bits. Here’s what I’ve worked out so far:
- Files are made up of 12 audio blocks, each about 0.9 seconds long. Each block appears to correspond to one 7×24 display screen.
- Mark (1 bit): Three cycles, 96 samples at 44100 Hz: 1378.125 Hz
- Space (0 bit): Four cycles, 256 samples at 44100 Hz: 689.0625 Hz
The editor runs nicely under DOSBox, so you can experiment and save samples as WAV files. Here’s a sample display with its corresponding audio linked underneath:
I’m not sure how much extra work I have time or inclination to put in on getting this working, but I hope that my preliminary work will be useful to someone (maybe this person).
Seems that Shangri-La Toronto wants to surround their building with a bright magenta billboard. This is the view from my office:
It’s so bright everything vaguely reflective on my desk appears to be pink. I’ve made a couple of calls to the City of Toronto – Sign By-law Unit and Toronto 311 and await developments.
Sign at Riverdale Library: Slippery trip hazard.
It’s actually the UK speed camera warning sign, but it looks quite a lot like an RB67 …
I discovered last week that GO don’t have a central announcement system. That means that unstaffed stations like Kennedy and Exhibition always leave their passengers in the dark. Plus, the e-mail announcement system only alerts you if the train is more than 30 minutes late. I think by that time I would have gone home.
No sign of that train yet …
I’ve been driving for 20 years. Seems a long time since I took that Mini Metro (which stank of Insignia aftershave – the instructor used it to clean the glass) from the BSM depot in
Pollokshields and puttered around the south side.
No speeding tickets, no parking tickets, and only one insurance claim. The insurers must be making a fortune from me.
I see that the number of Dexit terminals has reduced to almost nothing, and now they’re offering refunds of outstanding balance. Looks like it’s dead.
I’ve had a love/hate relationship with Dexit. It was almost a great idea, but offered no significant advantage over cash from the bank machine. I wonder how long it will be before you can buy the old terminals in Active Surplus?
Uhoh, there’s a huge Canada Computers opening just up the road; next to this sign, in fact. I’m glad I no longer commute past it; the temptation would be too strong.
Yesterday went to The Twelfth Fret and traded in the Goodtime for this:
It’s a Gold Tone Bob Carlin Signature. It sounds beautiful, and unlike me, plays like a dream. So if I’m not blogging so much, this might just be the reason.
We lost a cory the other night. There were no warning signs beforehand.
They’re setting up some kind of christmas filmset in the parking lot – an ad, maybe? There are many fake trees in the parking lot, some with lights, and what looks like rolls of fake snow. There are also a hotdog stand and a London Underground sign – wha?
I’m no fan of billboards, but I have to congratulate Mike of Finatics for sheer gall when he put up this sign. See the plastic shark on the building behind? That’s Big Al’s, one of the biggest aquarium stores in Canada. Mike’s probably not going to get any favours from them any time soon.
Just played with QCAD for a bit, and remembered how much fun I had doodling with my ancient Amiga CAD package.
The pier is about the only place in Goderich that you can’t see a “Go Kati Go!” sign.
While I write this, I am being observed by a young gull. A phalarope bobs around the breakwater rocks.
In town for the AWEA 2006 Conference. Pittsburgh looks like it has some interesting topography, and has some huge buildings downtown. Trying to get a GPS signal for the map (amid a bemused high-school prom crowd) was hard.
I’m at YYZ, and despite the Canadian passport, I’m still Mr Designated Searched Guy. Thought that the passport might’ve changed things, but no. Sigh…
It does mean I no longer have to do those dumb visa waiver things, yay!
And it didn’t help that part of one of the lighting panels started to fall off inside the cabin before takeoff, so we had to taxi back, get it fixed, and head back out an hour later. Gotta love Air Canada.
Paul and I often talked of doing this, but I see someone’s done it for real: they hacked the GO Train scrolly LED signs to read Stephen Harper Eats Babies.
