RasPi.TV Mailbag - July 2015

Today we’re getting a bit interactive. I decided to do a mailbag video, showcasing six of the things people have given me or sent in over the last few months. The items in question are… PiUPS Traffic Hat Official Raspberry Pi wifi dongle Shortcrust Plus Pi 2 (& B+) case Unicorn Hat Witty Pi You Tell Me Which One You Want Reviewed In More Depth I’m off abroad soon. I haven’t got room in the case to take all of these items. Let me know which is the most interesting to you and I’ll take […more…]

Raspberry Pi2 - Power and Performance Measurement

The new Raspberry Pi 2 has a quad-core CPU (BCM2836), but it costs the same as the previous B+. All that extra CPU power isn’t a completely free lunch though. If you use it, it’ll cost you slightly more electrical power than the B+. But how much? That’s what we’re here to look at. In my testing, hammering different numbers of cores in parallel, it worked out at roughly 50 mA (250 mW) per core. But before I show you the full results, let me back up and show you how we got them because […more…]

The FLIRC case for Raspberry Pi B+

FLIRC have made a new enclosure for the Raspberry Pi B+, which is going on sale today. The Pi Hut is importing these to the UK and is the sole distributor for UK and EU. Priced at £13 including VAT, it’s an attractive case made of cast aluminium (painted). It has an integral heat-sink, and comes with a thermal pad you can use to ensure good thermal transfer. It weighs 95g. This is what it looks like… It seems to be targeted at media centre Pi owners, which is not surprising given what FLIRC is. […more…]

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 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…]

Sep 292014

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…]

Turtlteck - Ryan's new Turtle Robot

Many of you probably will have heard of Ryan Walmsley, the guy who created Raspberry Pi tracker Rastrack. Ryan’s been working for several months on a robotics project he’s called Turtlteck. It’s basically a simple wheeled robot with a microcontroller board which he’s programmed to act rather like a classic “turtle”. You program it with the direction buttons and hit the middle button to make it ‘GO’. I backed the project on KickStarter early on because it’s interesting and because, even though it doesn’t directly involve the Raspberry Pi, Ryan’s budding electronics business stems largely […more…]

New Raspberry Pi Speaker from ThePiHut

I got a new speaker in the post yesterday morning. It’s been redesigned specifically for the Raspberry Pi by ThePiHut. I charged it for a few hours (it has an internal lipo battery, which powers it for 7 hours of use) and then plugged it into the 3.5mm stereo outlet of an HDMIPi screen. This takes the sound from the HDMI output of the Pi (so it’s digital and high quality, much better than the Pi’s analog output). I tested it with Bug Buck Bunny, which has superb graphics and sound. It also makes an […more…]
