Full pHAT

In April this year I designed a HAT-sized PCB that would allow two pHATs to fit on one Pi. I was thinking it might make a good “over the summer” KickStarter campaign. But events conspired against me. I had trouble tracking down a source of the right stacking headers and I needed a break over the summer. So I sat on it until recently. Then, a couple of weeks ago I found a suitable header and now we’re back on track. What no KickStarter? I’ve decided to crowdfund this project by taking pre-orders at the […more…]

RasPiO InsPiring - a new system of RGB LED boards controllable by Pi and just about anything

I’ve been playing with RGB LEDs on and off over the last year or so. They’re amazing things. It’s incredible to me that something so small can produce such bright and brilliantly coloured light. I’ve played with the Adafruit DotStar Pi Painter project (using APA102), which is enormous fun. Also the Pimoroni MOTE (also APA102), which makes everything plug-and-play. Then there was the McRoboface from 4Tronix (using 2 sizes of WS2812). Then back in October 2016 I bought 4 quadrants of 15 WS2812 on ebay to make a 60-element clock. And then one day, amidst […more…]

Pi Zero W - WiFi on the Zero for $10 and a gorgeous new case

Raspberry Pi launches the Pi Zero W today – on the 5th anniversary of the original Pi1 launch. The Zero W sports the same WiFi and Bluetooth chip as the Pi3B. It costs $10 plus shipping and local taxes. Since the Pi Zero release in November 2015, people have been conjuring up ingenious ways of getting it online, such as; ethernet via SPI; soldering a WiFi USB dongle to the back; kickstarter projects for ethernet add-ons; USB hubs providing extra ports; even an IoT pHAT It was clear that people could find a lot of […more…]

RasPiO Portsplus Picademy - NEW product.

If you’ve been hanging around the RasPi.TV blog for a while you’ll have heard of the RasPiO Portsplus board. It’s a little PCB with the Pi’s GPIO port numbers on that you can use to avoid counting pins when wiring up your GPIO projects. A few months ago I was visiting Pi Towers. Ben Nuttall mentioned that they use the Portsplus at Picademy, but sometimes people put them on the wrong way up and it causes confusion. The original Portsplus has GPIO port numbers one one side and pin numbers on the other side. It […more…]

New Raspberry Pi 2B 1.2 with Pi3 BCM2837 Processor

Back in September a new version of the Pi2 quietly appeared on Farnell’s website without a fanfare. It’s exactly the same as the original Pi2 except the processor is BCM2837 running at 900 MHz instead of the BCM2836. Why the New Revision? By changing processors to the Pi3’s BCM2837, the older BCM2836 can cease production and the Pi2 gets an upgrade to the newer, faster A53 CPU. To keep the BCM2836 in production in small quantities no longer made economic sense. I pre-ordered one immediately. It arrived yesterday and I tweeted some quick photos straight […more…]

Raspberry Pi Zero 1.3 Power Usage with camera

It’s only a few days since the Pi Zero 1.3 came out, but people are already asking for me to “fill in the gap” on my power chart. Which gap? The “Pi Zero shooting 1080p video” gap. With no camera port, the previous Pi Zero couldn’t do this, so there was no measurement to report. I’ve made some measurements this morning and here are the results… No Real Surprises I tried both old and new cameras and there wasn’t any significant difference (that I could measure) between them. The results are comparable to that of […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…]

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…]

RasPiO Pro Hat  - Putting Pi Ports in Perfect Positions for Productive Play

Today I launched the RasPiO Pro Hat on Kickstarter. It’s a Raspberry Pi Hat for GPIO tinkering (it goes perfectly with GPIO Zero). It arranges the GPIO ports in numerical order around a mini-breadboard, which, to my knowledge, has not been done before. It also replaces the RasPiO Breakout Pro (now end of life) because it protects all the ports from over-current and over/under-voltage as well. It should prove a very useful board for GPIO tinkering and education. Have a look at the video and pop on over to the RasPiO Pro Hat campaign page […more…]

New Official Raspberry Pi DSI screen launches

The official 7 inch DSI Raspberry Pi screen is now launched and available for purchase. It’s been a long time in the making, but the B+, the A+ and Pi2B have all been responsible for pushing this display to the back-burner. When there finally was some ‘engineering time’ to get on with it, hurdles were faced with EMC compliance and chip availability. But those hurdles are now overcome and the screen is now launched. And it looks great (click any photo for higher resolution). Video Overview Here’s a video overview. There’s more detail in the […more…]
