I got Windows 8.1 to bluescreen

I’ve had my laptop with Windows 8 (later upgraded to 8.1 with the first release of updates) for a few years now. I don’t understand all the anti-Microsoft hate. True, they seem to be following the good-rubbish pattern of old (XP good, Vista rubbish, Wi… Continue reading

433Mhz RF communication between two PIC microcontrollers

The Arduino VirtualWire makes communication between two microcontrollers really easy – simply send some data onto the TX module and it magically appears on the on RX module. We’ve already built most of this functionality using our Manchester encoding/d… Continue reading

Margate games: locating bullets with sound

I’ve been working on a system that uses microphones to locate where a bullet has hit the wall, so that I can make a digital firing range using lasers and Nerf guns. Since I posted last, I’ve been thinking more … There’s more

Margate games: Digital shooting gallery R&D

I can’t believe it’s already been two weeks since my first Margate visit and since then there’s been a burst of technical R&D. I’ve decided to recreate the magic of an old fashioned side show, with additional computers and lasers. … There’s more

Receiving Manchester-encoded data over a single wire using Oshonsoft

Having built a single-wire transmitter, it’s time to receive the encoded data.We’re running this code on a PIC16F883 on it’s own internal oscillator at 8Mhz. The code includes error checking, but not correction- i.e. if a message received is junk, it’s… Continue reading

Manchester Encoded Transmission using Oshonsoft

We’ve been playing about with one-wire Manchester-encoded data again, only this time using (our preferred) Oshonsoft PIC compiler. We’ve been using pretty much the same techniques as before, only this time, in BASIC rather than C.Here’s the first part,… Continue reading

Margate Games residency – revisiting Margate

It was my first visit to Margate yesterday since I was a kid. I walked around and got a feel for the town, and was lucky enough to get a tour of the dilapidated theme park, Dreamland. There are creepers … There’s more

Espruino – javascript on a microcontroller?

I’d forgotten all about this, until a parcel arrived yesterday, from Singapore or somewhere like that. I’ve been hitting eBay quite hard lately, so it could have been any number of things. But it turned out to be my Kickstarter reward for a project I b… Continue reading

Hall sensor tester

One of our board sections seems to have a fault.No matter how many times we introduce a playing piece over just one square of just one board section, there’s no data coming back from it.It’s not a design fault, because other, identical, board sections … Continue reading

Soldering SMT components by hand

A few people have asked about how we soldered up our working board game sections a short while back. Specifically, they asked about our pick-n-place machine and reflow oven (as it was assumed that this is the only way to successfully use SMT components… Continue reading
