JavaScript Pytool

I’ve had a great idea. At least I think I have. I’m going to try to make a JavaScript version of the esptool program that is used to download firmware into the ESP32 and ESP8266. If you’ve ever built and deployed a C program onto these devices you’ve run this program. It is how your program actually gets onto the device. It works really well, but to make it work you have to download it and then fi… Read more →


Beverley Westwood

This picture wasn’t taken with my Floppy Disk camera. I used the phone for this one. It illustrates quite well how we’ve come on in the world of photography. The picture is brighter, sharper and technically much better. But when I look at it closely I get the impression that there’s been some image trickery going on. the brightness of the sky seems go up and down a bit around the trees and the hor… Read more →

Playing with toys

When your programs fail it’s really useful to be able to look inside them and find out what they are doing. If you’re writing code for your desktop or laptop you can use a debugger to step through the code and see what is going on. But that’s not as easy when you’re using an embedded device. The program is not running on the machine that built it, and this means that you end up putting print state… Read more →

Stuck Lock

One of my favourite jokes comes from a Naked Gun movie:“Who are you and how did you get in here?”“I’m a locksmith. And I’m a locksmith.”I didn’t say it was a good joke, just that it was one of my favourites. I was reminded of this when searching the internets for advice on fixing sticking locks. Every website that found seemed to contain the phrases like “…which should only be performed by a train… Read more →


Floppy photos

We went out for a walk today and I took my camera that takes pictures onto floppy disks. It works a treat. The picture above has been slightly tampered in Lightroom, but I think it looks pretty good for such an old device. Each picture file is around 80K (which is very small) and has to undergo a lot of compression The camera clicks and whirrs happily after each photograph as it stores the picture… Read more →


Taking photos onto a floppy disk

I’ve wanted one of these for ages. And now, thanks to the magic of ebay and the resilience of consumer electronics, I’ve got one. It’s a Sony Mavica and it cost me less than 20 quid, as opposed to the hundreds I’d have to pay back when it was released in 1998. And it works. Very exciting (at least for me). It takes pictures onto a floppy disk. You can get around 12 or so pictures on one disk. The… Read more →
