Check out this thread: https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=59474 The second from last post (at time of writing) seems to suggest that you can run a Pi3 by simply connecting 3.3V to the 3.3V side of the regulator. I'd be interested to know if this really works. It may also...

Hi ZOR, the transistor connected to the Picaxe output turns on the mosfet (i.e. causes it to conduct) by lowering the gate voltage to 0V. This would allow us to also turn on the mosfet by connecting the gate directly to 0V via a switch, since the transistor is not damaged in any way by doing...

Sorry, I've got interested in this now. Here are the bones of an idea. Pressing the button for the first time turns on the mosfet, powers the Picaxe, and the Picaxe sets its output high for x mins. Subsequence button presses pulls the input low and the Picaxe extends its output 'high'...

Here is an interesting product that I noticed while scanning a popular electrical catalogue last night. Its a domestic wireless switch which generates its own electricity when a user operates it (kinetic energy); no wires, no batteries. Therefore it can be used just about anywhere, and the...

My wife bought me a LifeMax magnifier light, and its absolutely brilliant. It has a ring-light so shadows are minimised. You may have to stand the circuit board on a cardboard box or something to lift to the required height.

Despite spending many, many years playing with bits of wire and black insects (my wife's words, not mine) I have never ventured into the world of robotics. My view was basically; "so you spend several days building a robot, play with it for half an hour, then chuck it in the junk box, where the...

This system records video/stills of nesting garden birds. Although the complete system could be categorised as "video" the Picaxe part of the system is concerned with battery conservation. This bird box includes a Raspberry Pi, camera and an 08m2 Picaxe, and is powered by a 12V 12Ahr battery...

Thanks Technical. I didn't see it earlier when I scanned the options, but here it is...

My box has a floor, an entrance hall & a bed-sitting room. I could add photo-cells inside the hall, but wouldn't be able to tell whether it had been tripped by a hedgehog or a rat!

Many thanks Hippy for taking the time to respond. I think my main problem is that I don't understand Qemu. And I think this error... ...is probably because I need to install some qemu related packages. I've started reading up on qemu, and know that it can be used in 2 ways: full emulation...
