Run a K40 Laser Cutter from Your Raspberry Pi with K40 Whisperer

I bought a Chinese K40-style laser cutter about three weeks ago and I’ve been spending quite a bit of time playing with it learning how best to use it. It’s an eminently hackable design, and while mine could cut 3mm acrylic OK ‘straight out of the box’, there are many things that can be done to make it better, easier to use and more user-friendly. I’ve had great fun doing a whole host of upgrades and improvements to it, but that’s not what I’m focusing on today. Last week, Les Pounder published a blog article […more…]

How to Flash an SD Card with Larger than 4GB Image - Raspbian September 2016 update

Yesterday (28 Sep 2016) a new version of Raspbian was released with a brand new skin called PIXEL. I downloaded it on my Mac and tried to unzip it in the usual way. It threw an error, so I assumed the download was faulty and downloaded again. But the error persisted. GAH!!! My friend Albert Hickey (who runs the Egham Jam) had a similar issue on Windows… Les Pounder said it worked fine in Ubuntu though. Didn’t Unzip on Pi I tried unzipping it on a Pi, but that failed too. BOO! However, it was […more…]

How To Free Up Some Space On Your Raspbian SD Card? Remove Wolfram & LibreOffice

There are occasions when you may want to free up some space on your (micro)-SD card. If it’s getting full, or you want to store large media files, or install a large application, you may find you run out of space. There’s an awful lot of good stuff in the default Raspbian Jessie distro these days, but you may not be using all of it on all of your Pis. So, let’s have a look at which of the pre-installed packages take up a lot of space and could give us “an easy win” here. […more…]

Get_iplayer Raspberry Pi Update

Latest update here. This article is left intact for historical reasons. Last week there was a great hoo-ha as the BBC announced changes to iPlayer and the way it will work, going forward. Basically they removed the RSS program indexing system, which was used by quite a few smart TVs and also 3rd-party apps like Get_iplayer. Although this doesn’t stop Get_iplayer from downloading a file if you know the correct PID, it did break the functionality of finding the PID automatically with Get_iplayer. It also broke the PVR (personal video recorder) functionality. But within a […more…]

Google Coder on the Raspberry Pi - How to install

I was very keen to try out Google Coder for the Raspberry Pi as soon as I heard about it. I had some problems with it initially because the instructions on the Google Coder download site are/were fairly scant. It talks of an installer, which it later transpires is only for the Mac. The instructions have since improved a bit, but initially were hopelessly confusing. I hope the instructions will have improved even more by the time you read this, but below I’ll show you how I got it up and running. These are instructions […more…]

Emulators galore on one raspbian image

Carles Oriol has put together a raspbian image with just about every emulator you can imagine, including… ZX spectrum DOS / Windows 3.1 Commodore 64 Apple ][ Oric 1 Atari 2600 ScummVM Arcade (MAME, I think) The only one of note that I didn’t see was BBC Micro. I don’t know if it’s available for the Pi. (But there is RISCOS, of course) It’s a very impressive piece of work. No details yet if he intends to republish. It’s possible there may be some copyright issues if he does. For the moment, though, there is […more…]

How to install Fuse ZX Spectrum emulator on raspberry pi

How to install Fuse ZX Spectrum emulator in Debian Wheezy Beta and Raspbian On the Raspberry Pi site there is a thread about how to install this spectrum emulator in Arch. I figured it was time to have a go in Wheezy – just for the heck of it – and it worked. Not 100% – still can’t get it to make sound reliably and satisfactorily through HDMI, but I have managed to get it working well through the analog audio out – *so you can use headphones or speakers to get those primitive speccy […more…]
