I’ve got this Raspberry Pi connected to an e-ink frame. I’ve written a little program that generates random text prompts from a set of keywords. The text gets fed into a copy of Stable Diffusion and every few hours a new picture appears. It’s quite fun. Today I added a little web server to the app so that I can view past pictures. None of them are very good, but I find them fascinating.

Hepworth's Arcade

Sometimes you get the best shots just by looking up.

We went up town today and the weather was lovely. Of course I took a camera.

Hungry Claude

I’ve started using Claude Code. It’s very good. So good that I burned through 25% of my weekly credits before morning coffee. I’m going to have to learn how to pace myself.

New Raspberry Pi Magazine Available

The latest issue of the Raspberry Pi magazine is now out. It’s a really good read. It tells you, among other things, how to set up a local Pi as a “cloud” service you can access from anywhere. Very interesting. I’m going to have a go at that. There’s also an article from me all about making your own Wordsearch Clock.

Well worth a look.

Canon Autoboy Super 39-85

It’s not that I’m working my way through this book buying each camera. But I have managed to track down a Canon Autoboy Super 39-85. It was made in the 1980’s at a point where they had got rather good at this kind of thing.

It is quite chunky. It won’t fit in a pocket. But it does take really good pictures. The auto focus lens is super sharp, the auto exposure does a good job and the flash zooms with the lens, so your indoor pictures look great. It has a party trick; there’s a clip out remote control in the base of the camera you can use to take selfies from a distance. There’s also an “Infinity” button you can press to stop the auto focus making a mess of landscape shots.

YOu can get some nice out of focus effects

The detail in these flowers is really nice

They made quite a few of these. They are a bit too large to be totally fashionable so you can pick them up cheaply. Mine cost less than a video game, which is my standard benchmark for these purchases. If you want something distinctive to pull out at parties and when out and about you should take a look.

Bulb Mode

Camera shutters usually have a setting marked B. When you pick the B setting the camera holds the shutter open while the shutter button is pressed. You can use it to take pictures in poor light, or if you want to get artistic effects like light trails. The B stands for “bulb” mode.

Most folks think that bulb means “flash bulb” (as in a little glass bulb that is full of magnesium wire that is ignited to light up a dark scene) but this is not the case. It actually refers back to a time in the past when camera remote control was achieved by using shutters that could be fired pneumatically. You could fire the shutter remotely by using a rubber tube. One end of the tube was attached to a piston on the shutter, the other to a rubber bulb you could squeeze to trigger it.

I’ve been able to recreate this system using some 6.5mm laboratory tube and an air blower bulb. I would have liked to have had thinner tube, but putting a cable tie on the end helps it fit on the camera. It works well, although you have to give the bulb a hefty squeeze. I can now take pictures without pressing the button on the camera, which is nice.

My version of bulb mode doesn’t hold the shutter open while the bulb is pressed because the piston on the shutter is not airtight so the air pressure in the tube drops and the shutter closes after a while . And the whole bulb thing is actually a bit more complicated than my simple explanation. But I’m pleased I’ve now got remote control.

Pictures

Seem to have got both spring and Autumn in the same frame..

Sometimes pointing the camera up works well

Took the big camera for a walk this afternoon.

Awesome Hull Video

Not sure what Hull is all about? Watch this.

Apple Newton Keyboard Fixed

I love a happy ending. I now have a working keyboard. Ages ago I bought some electric paint, and it worked a treat. I just had to scrape off an insulating layer and then spread the paint all over the track to restore the connection and make a fix.

A smoking gun if ever I saw one. You can see the gap in the top track of the membrane at the bottom of the picture. I thought the green covering the ribbon cable was another layer of tape stuck onto the back of the keyboard membrane, but actually it is a layer of paint. So I scraped it off around the break and then clarted the whole thing in conductive paint. And it fixed the problem. The hardest part was getting the keyboard mechanism back in the case. That took two goes.

Many thanks to the folks behind this site, which told me how to take the keyboard to bits.

Apple Newton Keyboard Fun

How was your day?

I got a keyboard for my Apple Newton. It was cheap because the shift keys don’t work. So it’s little letters all the way. Both shift keys have failed, which makes me think it is a broken track somewhere.

After a ton of tests and complete disassembly I think I’ve found the fault. I’ve found a tiny gap in one track. I just hope my conductive paint hasn’t gone solid.

Properly home

Mowed the lawn today. I guess that means we are properly back home.

Hardware Meetup

There was a lot of stuff on show at the hardware meetup tonight.

Brain had brought a 3D printed skull (roll on Halloween), a demo of his person tracking software which spots actors in scenes and his spinny thing with lights which is getting a new propellor.

Ross had brought along his press detection testing rig which taps a piano key and then monitors the response from the sensor array on the keyboard. Ian had his audio MIDI magic (which I didn’t get a picture of) and I was trying to take portraits with the old camera, this time using a rubber bulb and tube to trigger the shutter remotely.

It turns out that we can trigger the shutter OK, but we need to work on framing the shots. The Instax film that we are using doesn’t fill all the frame and I kept adjusting the camera to point the wrong way each time. Although I did manage to get the fire extinguisher in the picture rather neatly. Ho hum.

The next meetup will be on Wednesday 7th May in Hull MakerSpace. I’m going to try a different camera for portraits for this one.

Yarn Bombing

The WI in Beverley have taken it upon themselves to add some decoration to a post box. Not something we saw at Walt Disney world, but charming nonetheless.

Nuclear Option

Nuclear Option is a fun game where you team up and try to set the world to rights by flying around in a plane destroying pretty much everything around you. I just can’t work out where they got the idea from.

We had a go tonight. It’s nice because you can work as a team. We had to protect our airfield and take over another one, while the computer controlled opposition tried to do exactly the same thing. I got shot down a lot, but I did manage to take a few opponents with me, which was nice.

The game is in early access and is therefore not too expensive. There is a nice range of aircraft which expands as you level up. I’m going to have to do some practice, but I’m enjoying it so far.

Labelling batteries as jetlag therapy

.. and I found a new font for the label maker

Feeling bad because you’ve just come back from a wonderful holiday? Stressed out by jetlag? Then why not put some labels on batteries? Worked for me.

In all seriousness, I’ve found these Hixon AA batteries to be very good. The are Lithium Ion based so they last a good while (the makers claim 3,500 milliamp hours).

Not jetlagged at all

Another memory

I was fairly sure I didn’t have jetlag. Not me. Not at all. Then I looked down and discovered that I’d just plugged the output of a USB charger into itself, rather than the phone I was supposed to be connecting. Oh well. Time for a lie down.

Back in Britain

..and we’re back. Smaller roads, dirtier cars, colder weather. Oh, and bed at home. Love it.

Heading Home

A great place for a burger

The good thing about having your home flight at 8:30pm is that you get an extra day tagged onto the end of your holiday. The bad thing is that you don’t know what to do with it. We spent a while squeezing things into suitcases and then headed over to Universal Plaza for lunch at the Chocolate Factory.

Then back to the hotel to play cards until we could check in, and then it was another Lyft up to the airport. Dropped the luggage early, found the gate and sat for a while reading and chilling. Then it was onto the plane and off into the sunset. Sort of. Well, we were flying north east

Universal Unlocked

Indeed

Our final “park day” turned out to be rather intense.

I love the artwork around the place

.. see what I mean

The Spiderman ride was excellent (and turned out to be Rob friendly which was nice). Other rollercoasters and rides were found to be excellent too, but this correspondent was mostly holding bags for these.

Not a real train

They have this stunning fake railway that runs between Hogsmeade and Kings Cross in two of the parks. It looks very realistic from the outside and the inside, with fake windows showing moving scenery and even Harry and chums waking past in the corridor.

It looks far to clean to actually be in London

We were first there

We had lunch in the Minions café was excellent. Then back to the room to pack.

Epic Cooldown

The universal universe

After all our exertions yesterday we are taking it easy again today. We had a gentle amble around the Universal theme park and then took in another movie in the afternoon. This time we saw “The Hail Mary Project” which was excellent. Rock hard sci-fi with a heart. Very enjoyable and tickets were on discount today.

It’s a good ride with a very hokey storyline

Poster art

The simpsons ride is excellent

One last park day tomorrow before we have to start packing our bags for home.
