Just heard from Microsoft that I’m an MVP for another year, which is awesome. Thanks so much folks.
I’m never quite sure what it is that I keep doing to get the award. But I’ll just keep doing what I’m doing and hope that it works.
Our next hardware meetup is in person, at Hull MakerSpace in Hull Library. It’s on Wednesday 6th, starting at around 5:30 pm and then going on until around 7:30 pm. We’ll be showing off what we have built and talking tech. If you want to see the new Raspberry Pi PICO W (which brings WiFi to the very popular controller) we’ll have some around too. Just turn up, we’d love to see you.
Had some great fun at Cottingham Day today. The Pie Bakery (aka Hull Pie) were there so we grabbed some pies in the morning, had them for lunch and then went back out for strawberries, scones and cream. They had a bike show as well, which included this beauty. The weather forecast was fairly horrid, but the weather turned out really nice, and the huge crowds that turned out seemed to be having a whale of a time. As were we.
Did the vacuuming today while wearing noise-cancelling headphones. Managed to do an entire room with the vacuum turned off……..
My PICO W devices arrived today. They look really nice. I’ve soldered a bunch of pins onto one of them and plugged it into my PICO Display Pack with the intention of making a tiny wireless message board. Unfortunately the Pimoroni image with the drivers for the display on it doesn’t support WiFi just yet. I’ve tried using this library with the WiFi enabled Micro Python firmware but I can’t get it to work. With a bit of luck Pimoroni will catch up soon and I can make something that displays a message each time I make a new blog post….
The shiny box is the wireless antenna
The Raspberry Pi PICO is an awesome device. Super cheap, super easy to program and super easy to connect to stuff. The only thing about it that I didn’t like about it was the lack of any wireless connectivity. That’s changed now, with the launch of the PICO W. This adds a Infineon CYW43439 wireless chip to the PICO which brings Bluetooth and WiFi connectivity. The new PICO W is physically compatible with the old one. The pins are pretty much the same, although three of them (ones you don’t use much) are now accessed slightly differently.
At the moment there are no drivers for Bluetooth and you can only use the WiFi from Micro Python programs (not C++ or Circuit Python). But I expect that to change pretty quickly once folks get to grip with the device.
There’s a really good description of the new PICO W plus sample code in this month’s MagPi magazine which you can find here.
I’m working on the introduction chapter for “Begin to code: Building Apps and Games with the Cloud”. It was suggested that I should write the introduction when I’ve finished the entire text. That way I’ll know exactly what ended up in it. I quite like this idea, but I think I’ll try and write the introduction first. I think it is better to have an idea where you are going before you start. And I can always revise it later…
It turns out that I can take any number of flower pictures. I hope you can too.
Mantis is a nice little game. Except that it isn’t nice. And it isn’t little. There are loads of cards, each of which poses the question “Which of the three colours on the back is on the front?”. Gameplay involves either scoring “I’m going to user the colour on the other side to match with cards I have and score points” or stealing “I’m going to use the colour on the other side to match with cards I don’t have and steal them from someone else”.
Get ten scored cards and you win. And that’s it. There really isn’t much else to tell. The game is beautifully presented, with an entire back story that will tell you a lot more about shrimps that you thought there was to know. The rules are simple, but how you apply them and what you do is up to you and can get surprisingly deep. This is not a game that you will spend the entire evening playing, but it is a great way to get the party started.
I’ve got all these things to do. I need to write the introduction chapter for the new book. I’ve got an article about the Chocolate Synthbox to finish. And, since reading HackSpace magazine yesterday, all I can think about making is a Magna-Doodle clock….
I’ve got an article in Hackspace magazine this month. This is good news for readers, but also good news for me as I need to buy some new shoes…..
Anyhoo, this article is all about making a 3D printed game. It tells you how to run Python code inside the FreeCAD modelling tool and create game pieces programmatically. You find the magazine in shops and there is also a free pdf download here.
I’m quite enjoying making silly sounds and tunes with the Chocolate Synthbox. It’s still a bit unreliable. I’m having problems getting some of the components to wake up in a correctly configured state, but when it is working it is great fun.
You’ll be able to find out all about the device and what it does in an upcoming Hackspace article.

Which one is running Windows 11?
When I bought my super-cheap laptop I noticed that xsonly had an even cheaper one that had a processor flagged as Windows 11 compatible. What the heck, it was only sixty quid. So I bought one. True to their word, Microsoft have now released an upgrade for the device and I installed it.
It works. Windows 11 runs perfectly. I’m not sure that I’d recommend the cheaper notebook though. I think it is cheaper for a reason - which is that it only has a dual core processor. The GeoBook 140 has a quad core device. The difference is noticeable when using the laptop, things are a bit more slow to arrive.
I rather like the Windows 11 experience though. Putting the task bar in the middle of the screen makes perfect sense after a while - you don’t have to move the mouse to the corner to do everything. Everything looks like it has had a spring clean and tidied up. Very nice.
If you want to run Windows 11 on a machine that is cheaper than a video game it is still available at the moment.
I don’t have a very good record buying train tickets. The Trainline app that I use looks very easy to work with until you try and use it. And then the fun starts. It didn’t help that I was getting repeated “Only four tickets left at this price” messages all the way through the process. There was definitely pressure to complete the transaction as quickly and smoothly as possible. And the app did nothing to help this.
It turns out that if you forget to do something, back out of the action and then go back in the context is subtly changed. The first time this happened I nearly ended up buying tickets from the wrong place. The stupid application changed back to the previous transaction details when I popped back out of a new transaction to change the number of passengers. Then, having fixed that, I went back in to complete the purchase only to discover I’d only bought one seat rather than two. At no point did the application say “Hey! You’ve selected the couples discount but only bought one ticket”. So I had to frantically jump back into the app “Only three tickets left at this price” and buy everything again. And I missed out on my couples discount.
Number one son says I should just buy my tickets from somewhere else. I’m thinking he might be onto something. I just hope there will be trains on the day we want to travel.
Going to the dentist is starting to remind me of piano lessons from years ago. Then I used to turn up nervously hoping that the teacher wouldn’t notice that I’d done no practice. With the dentist I turn up hoping she won’t notice I’ve done no flossing. As if.
I’m not sure why I worry about this so much. After all, the dentist gets paid whether I floss or not. In fact you could argue that me letting my teeth get into a mess just means more paid work for her. In which context the filling I need could be counted as a win.
I’m really going to start flossing more…
Look what they got me for Father’s Day. Thanks so much folks.
Not sure this will work every time, but I pass it on as a tip that has worked for me. If you are stuck trying to solve a problem it is sometimes a good idea to go off and try solving a totally different one for a while. I have a number of “background niggles” which are things that I would like to fix when I get round to it. I keep a list of these in my diary.
When I get stuck on a “foreground” problem in something I’m working on I will go off and have a look at one of my “niggles” for a while. If I’m lucky (and I have to be lucky) I’ll fix the niggle, come back to my original problem, take another look at it and then solve that too.
Forcing the brain to switch from one issue to another and back again sometimes allows it to pick up on something you didn’t spot first time around.
If you haven’t got any “background niggles” (lucky you) then you can do something different for a while and then come back.
I’m writing another book. You might wonder why I’ve just signed up to spend 6 months of my life thinking about nothing but JavaScript and deadlines, but I happen to like writing. So there.
The new book has the title “Begin to Code – Building Apps and Games in the Cloud”. It’s a follow up for “Begin to Code with JavaScript” with the aim of turning the reader from a programmer to a programmer who knows how to use the cloud.
I’ve already had a lot of fun putting together the overview and roughing out the sample projects. And I’m really going to enjoy turning out the text. Really
This is the latest “thing” I’m building. It is intended to serve as a “party printer”. It detects when people stand in front of it and offers to take their picture. After a countdown the picture is taken and then sent via Bluetooth to a printer that makes a hard copy of the image. You can see the tripod socket on the bottom of the device.
I’ve just about got the code working. The biggest problem has been getting the lens to focus. You have to do this by turning the lens in the camera. I was having a lot of bother screwing the lens in tight enough to get a sharp image. “No problem” I thought to myself, “I’ll use those really expensive angled pliers that I bought a while back to grip the lens and turn it”.
That didn’t end particularly well. As you can see by the massive scratch across the lens. The good news is that the scratch itself gave me something to grip on as I tried to rotate it. And it doesn’t look as if the image quality has been affected too much.
Now I just have to finish off the software and write up the device for a Hackspace article.
