Burnby Hall Tulip Festival

I'd not heard of Burnby Hall until this weekend. They are presently having a tulip festival, and number one wife wondered if I'd fancy going along an taking some pictures. 

Would I just.

So it was into a bag with a goodly assortment of lenses, tripods and kinds of other paraphernalia (that's the great thing about photography - plenty of scope for paraphernalia) and then off down the road to Pocklington. 

It was lovely. We got there nice and early when there was a bit of an angle to the light and it was nice and quiet. It's a great place to visit. Good food, good weather (at least today) and lots of tulips. We saw loads of families with picnics making a proper day of it. And there was even a brass band at 2:00.  

Not sure they've fully grasped how Secret Gardens work though....

Kodak Photo CD Fun and Games

Twenty years ago, when I was still learning how to take photographs, Kodak Photo-CD was supposed to be the next big thing. Keeping photographic negatives and prints was going to be so old-fashioned in the new, wonderful, digital age. 

Of course I bought into it. I got four or five rolls of film encoded onto this magical, future-proof, media. Of course, twenty years on all my prints and negatives are still around and usable. And the Photo-CD? Well, if you dig  around long enough you can find a program called Irfanview which will convert the files into something you can view again. I spent a happy hour or so this evening getting a bunch of pictures of the disks and passing them around the family.

The one above came out sort of OK, although I seem to have got a perfectly focused foreground and blurry background. So, twenty years ago I was still making the same mistakes I'm making today, just with a lot less technology to help out. 

Say Hello to Hull Pixel Bot

I've been spending the odd five minutes here and there designing and printing parts for a little robot that I want everybody to build. I've called it the HullPixelBot, because I want to turn it into a mobile pixel. I had lots of fun making my wedding lights a couple of years ago and so I thought I'd have a go at making a mobile version. The idea is that if I can get enough of them together and network them we could have a whole bunch of mobile coloured dots which we can display patterns on. 

It's kind of artistic. But in a technical way. 

Sooooo,  I want to get everybody making little Arduino powered robots. The target price for parts for the robot is less than ten pounds. I'm using very cheap stepper motors which work fine. They are a bit slow, but they provide a precision of movement which you just can't get with standard DC motors. I'm also using catapult ammunition (really) for the caster and four AA batteries provide the power. There are holes you can use to attach sensors and we will develop the design as we go along. 

I'm taking a bunch of parts to the C4DI Hardware Meetup on Thursday this week. If you fancy having a go at building a pixel bot, come along to find out more. 

Build a tiny Arduino powered robot for less than ten pounds. Stepper driven for accurate positioning. Find out more at www.robmiles.com/HullPixelBot

I made a tiny video. More hardware details to follow.

Update: The STL files are now on Thingiverse here.  There's also a HullPixelBot mini-site here

Marking time

We were back in the department, marking today. We are using the latest version of my Magic Marking program, which now has a search so that you can easily find the student you want to mark. It automatically opens the student submission, builds the marking spreadsheet and puts everything in the right place for returning to the students when the marking is complete. I saw some really nice great too, which was nice. 

Elder Sign Winners. Yay!

Tonight we managed something that I didn't think we'd ever do. We won a game of Elder Sign. We defeated the Black Goat of something-or-other by a cunning combination of skill, timing, luck and more luck. It was great fun. Owing to reasons of chance I was "Sister Mary", a woman with strong will, an ability to use locked dice and who is, sadly, not much good in a fight. But I was playing with a gangster and someone with second sight, so it all worked out well enough.

It took us two evenings to complete the game, but it was worth the effort.

Which Magazine Art

When I was younger I used to enjoy reading my grandmother's collection of Which magazines. This was way back in the sixties, when consumerism was just getting going.  I still get the magazine today. It has turned into a bit more of a lifestyle publication than it used to be; when it is recommending tumble driers that cost more than five hundred pounds as "best buys" you just know that something has come adrift. It still has teeth though, as its latest investigation into the way that products are getting smaller but not cheaper illustrates. 

However I think it had its heyday in the fifties and sixties, when there were many such issues to address. They also had a way with graphical design which was quite ahead of its time. Take a look at these covers for a glimpse of history. 

Ricoh Theta S 360 Degree Camera

I've seen the future. And it mostly works. On Saturday number one wife was injudicious enough to let me roam unsupervised down Tottenham Court Road, one of the more gadgety parts of London. Of course I came back with something. It's actually something I saw at the Gadget Show Live, but at the time I didn't think I knew enough about the device to be sure it was worth bothering with.

Anyhoo, with a bit of background research and a slight price drop I was able to nip into a shop and emerge with a Ricoh Theta S. It's a camera, but it does something that no other camera I've seen can do. It takes a full 360 panoramic picture in one shot. It is fitted with two wide angle lenses which are back to back. Each of them gives a 190 degree field of view, which means that there is enough overlap for two images to be stitched together to form the panorama. 

This is what a raw image looks like. The horrible pink bit along the bottom is my thumb and hand. It seems that things automatically know what to do with these images; when I uploaded one to Flickr it automatically uses a panoramic viewer when the image is opened. There's also a viewer you can use for your PC (which seems to produce higher quality images than the browser based ones) and an app for your phone (iPhone or Android) that you can use via WiFi to configure the camera, take pictures and download and view the shots. You can even display them as two images that you can pan around, which is perfect for Google Cardboard or the Samsung VR headset.

As far as image quality is concerned it is not great shakes. I think a good phone camera could probably out-perform it. However, you can set the ISO value (lower is better) and it has some HDR settings that improve things a bit. The images are fairly sharp, particularly close up, but I don't think the lenses have any form of aperture control and the shutters are electronic. 

However, for me the thing is not the absolute quality, but the fact that it can do this wonderful thing at all. I've had great fun playing with it. The pictures you get really give you a feeling of being there like no single image can. You can take video (although the quality is not that great) and you can also attach the camera to your PC and live stream 360 degree video.  You can send your images up to Google Streetview to add detail to places on the map. There's even an api that you can use to control the camera from your own software, and Ricoh seem pretty active with firmware upgrades and new software features. There are even some "professional" (i.e. expensive) things for sale in the App Store which take bracketed exposures and use them to create game environments.

There one hardware issue with the device itself that you need to be aware of though. The two lenses at the top stick out in a way that invites trouble. It's pretty much impossible to put the device down on a table without it being open to expensive damage. I've 3D printed a cover for the top which helps a bit, and I'll try to create a proper case of some kind.  The device itself is pleasingly chunky and very well made apart from that though. It has 8Gb of storage built in, enough for more than a thousand pictures or 25 minutes or so of video. Using it makes you feel a bit of an idiot though (or at least it did me). I ended up holding it on my head, which made me look very strange.

But I think when people see what this can do they'll want one. I also think that it would be a perfect feature to add on to a phone, if you could find a way of getting the field of view without the protruding lenses. It makes every picture into a selfie; but not in a particularly bad way. I know that whenever I go anywhere from now on I'll take this with me and get shots that I could not get any other way. Well worth a look if you want to see what everyone will be using in a couple of years.
