Christmas presents

Posted by jlangbridge Dec 26, 2017
There is a certain level of frustration involved when you get back home after a long day's work to find a little piece of paper in the letterbox - Sorry! You weren't home. Your parcel is waiting for you in <insert name of company that is sufficiently close, but closes too early>. Oh well.   Anyway, three days later, I managed to go to said shop and get my parcel. My girlfriend drove me, and her expression was priceless when she saw the size of the box waiting for me. I smiled, tryin ...
Here's the work from one of my students. He read somewhere that you could put oscilloscopes into X,Y mode to print graphics (I think the original post talked about porting Quake to an oscilloscope), and so he decided to play around during the lunch break. Our oscilloscopes aren't the best in the world, but the results aren't too bad!     He found an old cathode ray oscilloscope, we'll try that next week to see what happens. ...

More gifts from e14?!

Posted by jlangbridge Nov 19, 2017
A parcel arrived. Things like that do happen, only I wasn't expecting one. Curiosity got the better of me, so I opened it up. And smiled. Element14 sent me a present!     Well, thanks element14! That's very kind of you!   The t-shirt is size M, and I think that my friends over at e14 have vastly underestimated my physical size (height and, unfortunately, width). Well, things have changed quite a bit recently, I'm an IoT lecturer at a graduate school of engineering, and I have ...
Time to create a supercomputer! ...
Note: Details of this incident have been left intentionally vague, for several reasons. This also occurred a few months ago, dates also have been left vague.   It's a little after 7AM, and I'm tired. I woke up at around 5 to get ready, facing the freezing morning, and now I am on a high speed train, on the way to a major city. THe sun isn't up, and won't be here for a while yet. I almost feel alone. If everything goes well, I should arrive in less than 30 minutes, and go to an engineering ...
The teachers walk out of their classrooms to their assigned places, and in theory, the children should follow in single line, calm and quiet. It's Friday, as far as the children are concerned it's the weekend, and so nothing is calm. I'm waiting for my daughter, but this time she'll stay with her mother for 30 minutes, I have a meeting with a teacher, CodeBug in my laptop bag.   Parents come and go to collect their children, the remaining children are taken to a playground to let them rela ...

Codebug in schools

Posted by jlangbridge Mar 30, 2017
Getting ready to visit a local school with my Codebug and accessories. I've created a few applications to show to the teachers; the "Hello, world!" application is a must. The Fruit keyboard is awesome, and I've also created an RGB wand program to let kids play with resistors, and create colours. ...
Just a quick flashback I had this weekend. While clearing out the NAS, I came across this. A little review I did long before the Roadtest system existed, I was contacted by element14 to review a board that, quite literally, changed my life. So once again, thanks element14 for saving me. Literally. If you want to skip the boring stuff and go right to the reason why, it is hidden inside "My first program". He is now 2 years old and still doesn't know.     I was thrilled to be asked to r ...
The bell rang a few minutes ago, and somewhere in the dense mass of kids, my daughter is coming to see me. She thinks I’m coming to get her and take her home. She’s right, of course, but this afternoon, I have something I want to do first. Like a magnet, all I have to do is wade in the middle of the flow of children, and she sticks to my leg like a limpet. “Bonjour papa!”, she says, and I don’t think I’ll ever get over that smile. She is curious as to why we h ...
So, I got #BitByTheBug. I posted something quick on Twitter and G+, and once again, thanks element14 for your support!   Before actually showing this to anyone, the best thing would be to test it myself, and see what all the fuss is about. It looks cute, it looks well designed, and the website is pretty well done, but how does all that fit together? The "Hello, world!" application took, literally, less than a minute, and I'm (apparently) an expert in "Hello, world!". I've been cited on Wik ...

Dilemmas, dilemmas...

Posted by jlangbridge Jan 10, 2017
There was a parcel waiting for me today. I hurried back home to see what it was. The fact that it had "element14" written on it made me even more excited! And here is what I got: I've just moved into a new house, so some geek decorations are more than welcome! The dancing element14 man is going to be a perfect fit (but I will have to be careful of my daughter, she already wants it!). As for the Raspberry Pi 3, I have a lot of ideas. My RPi 1 isn't fast enough to run Redmine for my books, cour ...
I’ve been teaching students of all ages, from 8 years old to adults, and one of the most common things I’ve heard is about bouncing. Sooner or later, we are faced with this rather simple problem, so what causes it, and what can we do?   Let’s start off with a simple schematic. Press the button, and VOUT goes to VCC. Release it, and it goes back down to GND, through the pull-down resistor. Counting sheep  In theory, nothing could be simpler than a switch. Make an ...
I was asked to review the STMicroelectronics STM32F0-Discovery board, a high-quality, low-cost board designed to show off the technical capabilities of the STM32F0 microcontroller, while remaining versatile enough to be used for applications immediately.   Box Contents The STM32F0-Discovery comes in a nice package, with colourful illustrations, and some text highlighting the advantages of the board. The board itself is well protected, and should survive even the harshest of transport. The p ...
