A few weeks ago I was approached by the production company that makes the Gadget Show. They wanted some shots of things people have done with their Raspberry Pi. So I invited them to browse the RasPi.TV YouTube channel and see if there was anything suitable. In the end they selected clips from four of my videos, I gave them permission to use them, and last night the show was aired. The videos used were part of a ‘Raspberry Pi hack’ slot involving making an internet radio. You can find the whole show here Here […more…]
I’ve been using lithium polymer (lipo) batteries since 2006, when I nervously shelled out £30 for a 3 cell 1600 mAh 10C HiModel lipo to power my EasyStar RC plane. I also spent about the same on a charger and balancer for it. Thankfully, all these things have come down a lot in price since then. I don’t think I’d expect to pay much more than £10 for an equivalent battery now. Typical lipo batteries for large devices have multiple cells. A lipo cell has a no-load resting voltage of 4.2 V when fully charged […more…]
I went to the Cambridge Jam yesterday and displayed HDMIPi production model #1, met lots of people, including Eben, Liz, and a multitude of Pi enthusiasts and bloggers (quite normal for a #CamJam). There was also a CNBC news crew there to film some Pi action. They shot a brief clip of me doing something like this… Matt Hawkins @RPiSpy kindly took this one for me using my camera. Good job he’s not a monkey, or we might have a copyright dispute. It was really nice to spend some time chatting to Matt. (Thanks for […more…]
You may remember seeing the special UNICEF edition HDMIPi, which I blogged about in a guest post on the Raspberry Pi Foundation blog a few weeks ago. This was a temporary solution to get them up and running quickly before the mainstream HDMIPi gets going. It’s a 10″ screen, a bit more expensive than the 9″ regular HDMIPi. It’s currently using a standard driver board. I visited Dave at Cyntech on Monday to discuss various HDMIPi related things. I walked away with one of the UNICEF edition demo HDMIPis, which I decided to take and […more…]
I’m publishing this post just after we hit 2 million page views, which will be around 1600 on Friday 13th June 2014 (lucky for some). It’s interesting this week that the Raspberry Pi Foundation has announced sale of 3 million Pis. We can’t quite match that, but let’s have some fun with stats anyway… 3 Million Pis sold – announced this week 2 Million page views on RasPi.TV – reached today 1 Million minutes of video watched on the RasPi.TV YouTube channel – in the next couple of weeks 1 Million visitors to RasPi.TV blog […more…]
Last Saturday (7th December) there was a Raspberry Jam at Cambridge Institute of Astronomy. This one was a bit different from previous jams because we had some beginners’ Scratch workshops for children in the morning. I was tasked to lead the workshop. The support was tremendous. There was a small army of people setting up ~20 Raspberry Pi systems when I arrived. Another small army assisted with the workshop itself, intervening when the children needed a prod in the right direction. Thank you to all these helpers. It couldn’t have been done without you. We […more…]
Just back from a week in Hong Kong and Shenzhen. Shenzhen is the capital of the Chinese electronics market. If you buy components on ebay, chances are they’ll be shipped from Shenzhen, and through Hong Kong. Shenzhen is a large and sprawling city. There’s an awful lot of new construction going on. Every time we went to see a supplier, we went past dozens of new blocks of flats/apartments being built. And we’re talking skyscrapers, each and every one of them. It was a really busy time there and I didn’t get many pictures, but […more…]
