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…]

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…]

Programming a KickStarter Tracker in Python. Part 1.

Ever since the HDMIPi KickStarter I’ve been very interested in watching the progress of other campaigns. I’m following four or five Pi-based campaigns at the moment. Are they going to make it? Are they not? It’s nice to keep an eye on things. But monitoring more than one or two wastes a lot of time. Wouldn’t it be nice if I could have a little computer and screen set up so that it checked these campaigns, say, once a minute, and reported on how they’re doing? I know there’s a decent Python library called urllib2. […more…]

Raspberry Pi SmartWatch Joke

A Raspberry Pi SmartWatch? You’re kidding me right? Errrm. Yes. I mean… Well… This has a lot of the functionality of a smartwatch, but it wasn’t built for that purpose. It’s a little big, for starters. Let me back up and explain. Last week, Apple released photos of their new smartwatch. Twitter, Google+ and every social network was awash with photos, comparison photos, criticism, analysis and good old-fashioned Apple-hating. By Thursday I was rather bored of it all, so I decided to make a joke tweet. I had this rather large Vacuum Fluorescent Display (VFD) […more…]

RPi.GPIO - port function checker

A few weeks ago I blogged about RPi.GPIO updates for the model B and updated my RPi.GPIO documentation and quick reference sheets. But there was one feature I held back on because I needed a bit more time to mess about with it. (And then got busy with other things.) So What Was It? gpio_function() Another RPi.GPIO feature that sneaked in while I wasn’t looking is gpio_function() This is a feature that’s been inserted in RPi.GPIO to enable you to query the setup status of a port to see how it’s configured. import RPi.GPIO as […more…]
