Gert VGA 666 review and video

Aaron Shaw from Pi-Supply sent me one of his early Gert VGA 666 adaptors for testing and comment, so I thought I’d share my findings. I followed the diagram in Gert’s manual. It’s a fairly simple build, just 20 resistors and two connectors. It took about 20 minutes, being careful to get all the resistors in the right places. The hardest part was the stacking header. The final product will ship with a slightly shorter stacking header. This should be a bit easier to solder. To get it working on the Pi, you need to […more…]

Raspberry Pi A+ Cases

In the 11 days since the Raspberry Pi A+ was launched, a few different case options have materialised. Here is a little video walkthrough of the options so far… Naked Pi – no case at all Altoids tin – yes the A+ actually fits in one (see the video) Cyntech/ModMyPi case – this is a B+ case, but the A+ fits in it too, albeit with plenty of room to spare A+ Pibow Royale Coupé – Pibow specially designed for the A+ 3d printed cases Mike Redrobe’s @RasPiTV @RPiSpy @climberhunt I just made a minimal […more…]

The Raspberry Pi Family

Now we have the A+, I thought it’d be a good time to celebrate its ‘birth’ by having a rundown of the various mass-produced models of Raspberry Pi. I had a look through my collection and was somewhat surprised to see that I have 10 different variants of Raspberry Pi now. There is one I don’t have, but more about that later. Here’s the family photo. You can click it for a higher resolution version. Rev 1 Model B In row 1, column 1 we have the Rev 1 model B. Although I was up […more…]

Raspberry Pi A+ How Much Power Does It Need?

Two Raspberry Pi A+ arrived from Farnell yesterday, so I spent the afternoon doing some power measurements. I also made a comparison video showing power measurements for an A+, a B+ and an old model A Pi. As before, when I did a similar thing for the B+, I used my trusty eMeter. But this time I used it inline with an ISO-TECH IPS 3303D bench power supply (at 5.2V) to corroborate the readings. Methodology I wanted to see how much current each Pi would consume under four circumstances…. Idling in command line – low […more…]

Raspberry Pi Model A+ Launched Today

Today, Raspberry Pi launches its new Raspberry Pi A+. Just like the model B was upgraded to B+, the model A now gets some love. So what’s it like? Essentially, it’s like a model B+ with the USB and networking end cut off. When I was at Raspberry Pi HQ a couple of weeks ago, I was allowed (under strict NDA and embargo) to shoot some photos and video. Here’s what it looks like… So What’s New & Different? The first three are the main changes – size, weight and cost. The rest are pretty […more…]

Get_iplayer Raspberry Pi Update

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 very short space of time there is a software patch. (I […more…]

A Visit to Pi Towers.

On Wednesday I went to Cambridge to visit the Raspberry Pi Headquarters, affectionately known as ‘Pi Towers’, to hang out for the day. I met and talked to pretty-much everybody during the day. ‘Everybody’ is now quite a lot of people. There must be about 20 people working at Pi Towers now. In May there was a large, unoccupied space on one side of the office. This time, that space was full of people working on computers. Raspberry Pi has recently hired a bunch of new engineering talent as a result of Broadcom closing down […more…]

Do you want touch on a Raspberry Pi screen, and if so, why?

Google+ has recently launched a poll feature. I thought it’d be fun to see what people’s attitudes are towards touchscreens on the Raspberry Pi. So yesterday I started a little poll. If you’d like to add your voice, you can vote with your G+ account. If you don’t have a G+ account, feel free to leave a comment below. (If the poll doesn’t appear embedded above, you can find it here.) Early Results At the time of posting, the results were… So what do you think? Do you want touch on a Raspberry Pi screen, […more…]

Programming a KickStarter Tracker in Python. Part 2.

So this is part 2 of the KickStarter Tracker in Python. (If you’ve not seen part 1 yet, that’s here.) We got the basics working last time. Now we want to make it look nicer, add more campaigns and have it running continously. So first let’s see about how we can introduce some colour… Adding Colour To Console Output There may well be more elegant ways to get the job done here, but I found a way that uses what’s called “escape sequences”. These are basically codes which can be used to modify the characteristics […more…]

protocam

In my previous blog post I started a series on how to program a KickStarter tracker. That will continue soon. In the meantime, one of the KickStarter campaigns I’ve been tracking is for a nice little board called the ProtoCam. It’s a simple, but original, idea by Richard Saville, who blogs under the name of ‘AverageManVsRaspberryPi’. (His emphasis is on quality articles, often with complete ‘how-tos’ for specific things he’s learned to do.) So he came up with this original idea for a prototyping board with space for a Pi camera on. You can put […more…]
