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…]

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…]

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…]

PiHut WiFi dongle vs Edimax - Power Usage

At the May CamJam, Jamie from The Pi Hut handed me a couple of his Raspberry Pi Wifi dongles for testing. I did some measurements a week or two later on a Raspberry Pi model B and sent them to Jamie. But I thought it would be fun to repeat this now with the new B+ and show all the results together. I’m doing a comparison test against the Edimax EW-7811Un which is my current ‘Go To wifi dongle’. Differences & Similarities? The Edimax is very slightly smaller. Both have blue LED activity indicators. The […more…]

Raspberry Pi Compute Module

The Raspberry Pi Compute Module was launched yesterday and I felt I owed it to you, dear readers, to get one. ;) OK. So, maybe it’s not fair to blame you guys for it. I’d have bought one anyway, but you helped me to not dither over the decision. I also have ideas for something I might do with it. But that’s top secret, so don’t tell anyone! So What is the Compute Module? It’s a small module in the same SODIMM form factor as a laptop memory module. You can see it in the […more…]

Bitscope Micro. USB Scope that works on Raspberry Pi.

When I first saw the Bitscope Micro on the Raspberry Pi Foundation blog, it ‘ticked all my boxes’. A couple of weeks later, when Pimoroni tweeted about having the first batch in stock, I ordered one immediately. In my circumstances, it would have been rude not to. Why? The reasons are too numerous to list them all, but here are the first few that spring to mind… I need a small, portable, USB scope since I spend about 20% of my time abroad and take my work with me. It’s also a logic analyser – […more…]
