I’ve just released the first versions of the new Javascript analogue and digital simulators onto this website. After the sad demise of Silverlight I’ve been translating the demos I use most into Javascript.  This has taken a while, since I’ve … Continue reading →

Since we no longer use it for teaching here, there seems no reason not to open-source the network simulator DANSE.  So I’ve just done this: it’s now available here: https://github.com/dajp1/danse It’s not in a very friendly format; I’ll wait to see … Continue reading →

I know it’s been almost two years since my last post… but the site is still active, I am still updating things, and I do have hopes for it in the future.  This is just a quick note to let … Continue reading →

For some reason the amount of spam comments getting through onto this site has dramatically increased recently.  Annoying.  I’ve had to respond by shutting down comments on most pages… sorry about this – but you can always email / tweet … Continue reading →

After all this time – someone reported a bug in the analogue simulator, and it’s a stupid one.  Connect two terminals of a potentiometer together, and the simulator can’t cope, it gets the currents entirely wrong.  Fixed now, but I … Continue reading →

This is quite exciting.  I’ve just heard (thanks to ResearchGate) that “An Introduction to DANSE” has been cited!  Ivan Minakov and Roberto Passerone have discussed it in their paper “PASES: An energy-aware design space exploration framework for wireless sensor networks”. … Continue reading →

I think I’ve got all the types of questions I want to have into the circuit theory app now, and sorted out what problems I know of in the calculator. It would be really helpful if a few people could … Continue reading →

OK… so I’ve been working on this new thing. I was going to call it “MathPad” until I googled it and realised that there was already a MathPad. However, the names of solutions in Visual Studio are really hard to … Continue reading →

Just a check of things in progress and things coming up. 1) The circuit theory test app is almost complete now… although I’d like to add a few more questions (one set about how to read oscilloscopes, and another about … Continue reading →

Just in case anyone notices – I’ve just released a new version of the digital simulator. This one attempts to automatically fix wires that appear to be connected the wrong way round (in this simulator wires have a direction, and … Continue reading →
