RasPiO GPIO Zero Ruler

You may remember this time last year I KickStarted a 6-inch ruler with the most important RPi.GPIO code on it. I’ve been using it myself an awful lot in the last year when coding. So it won’t surprise you to learn that I’m now doing another one for GPIO Zero. Since GPIO Zero is about the easiest way imaginable to get into Python GPIO tinkering, I think this will be really helpful for people. I’ve already been using the prototypes and find them an extremely helpful reference. Here’s what it looks like… It’s twice as […more…]

Raspberry Pi Zero 1.3 with camera port

A new Raspberry Pi Zero with camera port is released today. It’s revision 1.3. Some power circuitry was moved and some unpopulated pads at U13 were removed to make space for the new mini camera port which is right on the end of the Pi Zero 1.3. Other than that, the new Zero looks much the same as the previous version. I did a little walkaround video, showing use of the camera port and camera output. Adding a camera port to the Zero has opened up a whole new range of project possibilities. It’s added […more…]

How To Free Up Some Space On Your Raspbian SD Card? Remove Wolfram & LibreOffice

There are occasions when you may want to free up some space on your (micro)-SD card. If it’s getting full, or you want to store large media files, or install a large application, you may find you run out of space. There’s an awful lot of good stuff in the default Raspbian Jessie distro these days, but you may not be using all of it on all of your Pis. So, let’s have a look at which of the pre-installed packages take up a lot of space and could give us “an easy win” here. […more…]

New 8 Megapixel Raspberry Pi camera 2.1 launches

The new 8 Megapixel Raspberry Pi camera is released today. It’s fully backward compatible with all camera-enabled Raspberry Pis produced to-date. It uses a SONY IMX219 sensor capable of 3280 x 2464 pixel stills. It’s mechanically almost identical to the previous camera model (V1.3) except for rounded corners on the PCB – and there’s no red LED on the front. There’s also a NOIR version being released at the same time. They both support 1080p30, 720p60 and 640x480p90 video. Here’s a video overview… Specifications Lens: Fixed focus Megapixels: 8 megapixel native resolution sensor Camera Resolution: […more…]

Raspberry Pi Family Photo updated to include Pi3B 29 Feb 2016

It’s become a bit of a new model launch tradition now that I release a new “Pi family photo” with all the main revisions of Raspberry Pi in it. I’ve done things a little differently from last time in order to get a better resolution result. As usual I make this 1500px version available to the world under a CC-BY-SA-4 licence with the only condition being that the RasPi.TV credit stays intact. Aside from that, it may be used as you wish. I have ‘gone to town’ on this one slightly. Where previously I’d always […more…]

How Much Power Does Raspberry Pi3B Use? How Fast Is It Compared To Pi2B?

The Raspberry Pi 3, launched this week, is more powerful than the Pi2. It also requires a bit more electrical power if you’re going to be hammering those four A53 CPU cores. How much more? The recommended PSU is 5.1V, 2.5A, which is 0.5A higher than for previous Pis. That doesn’t mean the Pi itself needs that much, but with four USB ports onboard, the PSU has to cater for power-hungry USB devices as well. I usually publish some power measurements each time a new Pi is released. But this time I learnt something new […more…]

Raspberry Pi 3 model B launches today - 64-bit quad A53 1.2 GHz BCM2837

Raspberry Pi 3 model B launch is today’s big news. The new Pi sports a 64-bit quad-core ARM Cortex A53 CPU with VideoCore IV GPU packaged into the new BCM2837 chip. This 1.2GHz CPU offers ~50% speed improvement over the Pi 2’s BCM2836. Video Overview Pretty much all the information and impressions I have of the Raspberry Pi 3 model B are in this short video… …but if you prefer to read, it’s all here too… Now With Built-in WiFi & Bluetooth The other major news is that the Raspberry Pi 3B now has built-in […more…]

Always Test Everything - Twitter App Update

I’m a firm believer that you should always test things in advance. It helps avoid unexpected last-minute panics when things don’t work as you expected them to. On Friday I’m going to pick a winner from my twitter followers using the twitter app script I wrote back in October 2013. My Joey from @gooligumelec just arrived. :) I have a spare I will give to a randomly selected follower on Friday. pic.twitter.com/yGtwATYXng — RasPi.TV (@RasPiTV) January 5, 2016 It Still Works, But… Since I had no idea where the SD card with that old Raspbian […more…]

Raspberry Pi Zero - Updated Pi Family Photo

With each new release of Raspberry Pi, I usually do a new family photo. It’s getting harder and harder to fit them all ‘on the sofa’ and get them all smiling. The way I’ve always done it is “all in one shot”. I may change this for future versions in order to get more definition. We’ll see. (As usual, more ideas than implementation time.) I am very happy for people to use this photo if they wish to do so provided the RasPi.TV credit stays intact. I make it available at 1500px resolution as CC-BY-SA. […more…]

Raspberry Pi Zero - Power Measurements

Since the Pi Zero is small and eminently wearable, I thought I’d take some power measurements as this will be useful information for people to plan their projects. So I ran my usual series of tests and updated the table and chart showing all consumer models of Raspberry Pi. In my standard tests, I measure the current consumption, using the calibrated shunt on my Emeter, while the Pi is: Idling; Loading LXDE; Watching HD video and Shooting HD video. Since the Zero has no camera port, shooting video is not applicable, but all the other […more…]
