Real (?) wizarding duels with Raspberry Pi and T.E.N.S.

by  •  • 0 Comments

Allen Pan of Sufficiently Advanced decided that Google’s voice recognition service wasn’t being used for the right stuff. So, he hooked up a Raspberry Pi to the service for a far more magical mission. Wizard Analogue No-Magic Dueling Simulator (W.A.N.D.S.) is Harry Potter-meets-Laser-Tag – the Pi detects the speaking of ‘spells’ and then triggers an infra-red tipped wand. The infra-red signal is picked up by an opposing player’s receiver and then an Arduino hooked up to a T.E.N.S. machine delivers light electrical shocks to various parts of their body. This gives a palpable sense of being ‘hit’ without doing any damage. There is a bit of a delay while the voice commands are piped to the cloud and received back again, making it not-particularly-instant, but it’s still pretty cool! See it in action in the video below:

Thonny on Raspbian – the new Python IDE for the Raspberry Pi – MagPi guide and my quick review

by  •  • 1 Comment

There’s a new IDE (Integrated Development Environment) on the block. Called Thonny, it has just been added into the Raspbian image. The MagPi has done a great tutorial and walkthrough of the features of the editor here.

Opinion

I recently attended a Raspberry Jam at Pi Towers and was lucky enough to take part in a workshop run by Ben Nuttall. The workshop, which taught us how to use GPIO Zero’s remote control features, along with other examples using the library, was excellent. Ben made a risky move and got us to use Thonny rather than IDLE, the de-facto editor for Python. I have to say, I was very impressed. Instead of the pop-up execution window you get with IDLE, Thonny runs the code in a Shell tab below the coding window. This makes it feel much more integrated than IDLE, and much tidier as a result. There are a lot of features (for which take a look at the MagPi article linked above) including step-through and variable debugging in Thonny that we didn’t touch the surface of, so I can only give you a surface-level opinion. Personally, I think everyone who writes in Python should take a look at Thonny. It’s not perfect, I’m sure, but it is an excellent piece of software and well worth a go.

Pimoroni Pirate Radio for the Raspberry Pi – review from RasPi.TV and my opinion too!

by  •  • 0 Comments

Alex Eames has reviewed the Pimoroni Pirate Radio kit which features a Raspberry Pi Zero W. The kit, which requires assembly, costs £40 and includes the Zero W and most of the parts you need inside a nice project box. You just need to add an SD card and Pi power supply or USB battery. Read Alex’s review here. (Photo credit: Alex Eames)

Opinion

I got hold of a Pirate Radio kit myself recently. It really is very cute and is a nice blue colour with a frosted perspex front. The VU meter on the side is a nice touch, although I would’ve preferred it if it was a bit more responsive at lower volumes, but I guess that’s just a case of tweaking the Python script. The software itself is good as are the instructions for assembly and software installation, although you will need to hunt around for that pesky configuration file that lists the playlists. I managed to find it eventually but can’t remember where it is right this second. The web interface that you can use is a bit basic, but functional. The sound produced by the included speaker isn’t stellar, but then what do you expect for something that small? However, it’s easily slightly-better-than-radio-quality, so no complaints here.

I enjoyed putting the kit together (as Alex said in his review, a video might’ve been nice and a bit clearer, but heigh ho) and can recommend it to anyone who wants a little Pi-powered radio.

They’re out of stock at the moment, but you can see them on the Pimoroni shop site here or on The Pi Hut here.

DIY camcorder is hyper-slim and makes for a great Raspberry Pi project

by  •  • 0 Comments

Wayne Keenan wanted to build a hyper-slim camcorder. So, he took a Raspberry Pi Zero W, a HyperPixel screen, a small camera from Pimoroni, a LiPo battery and some other components, soldered and stuck them together and, voila, a tiny camera! He’s written the whole project up on Hackster where you can learn more.

He’s called it the Picorder… But I won’t hold that against him… 😉
