Charlie’s Radio Station

Today the boy started asking how radio stations work so we took apart an old in-car FM transmitter and built a little radio station setup around it, all housed in a box we built and painted. Flicking the big switch at the front and talking into the microphone will see Charlie broadcasting his shows around the house and garden.

The idea is to have one of those ‘On Air’ lights (hence the big hole at the front) illuminate when there’s a show going on.

 

The Portable Web SDR Receiver

I’ve been a big fan of radio for most of my life, especially the ham radio side of things. Luckily nowadays with the wonder that is the internet, there are many convenient ways of listening in to amateur radio transmissions without the need for expensive kit. If you fancy having a go yourself you can download a copy of my beginners guide to Web SDR and amateur radio that gets mentioned in the video below here.

So this week I started on a very exciting project, building a portable listening receiver that hooks into Web SDR setups around the globe. My favourite one of all has to be the one located on the site of an old nuclear bunker here as I find the 2m band is best for picking up voice transmissions.

The idea was to have a nice portable box that you can carry over one shoulder that will allow you to comb the airwaves whilst on the move. I also included a Morse code translator that will decode any Morse that is picked up and display the message on the small LCD. To finish it off I found a retro handset that someone had bought me for a present years ago. I had originally wanted to incorporate an internal speaker inside the box but including the old style handset just seemed an even better idea.

I love this project and I look forward to taking it out and about with me.

Drawn to the Screen

My slow burning project of last year has finally taken shape in the form of Drawn to the Screen, where you can download and make your our working cardboard television. The idea is simply to draw on the paper ‘film’ strip before winding around the pencils. The drawings come to life as they pass by the screen. As all the dot work from previous art works started to give me headaches, I’ve been looking at other means of finishing pieces as well as imaginative ways of delivery and I think the Cardboard TV is a good one.

The site has recently been mentioned by a couple of my favourite artists and as a result popularity is growing. Click here to check the site out and maybe make yourself the star of the show.
