Development of a new product - RasPiO Breadboard Pi Bridge (BBPi)

Today I launched the RasPiO Breadboard Pi Bridge (BBPi for short). It’s a PCB that breaks out all the GPIO ports of a Raspberry Pi in order on a half-size breadboard, complete with a Perspex platform to hold it all nicely together. It’s a clean, robust and elegant solution for simple electronics tinkering with Pi. This is what it looks like… If you want to snag one of the last 26 (at the time of publication) early-bird offers, use the code EARLY at the checkout, but be quick. Development Process I thought it would be […more…]

RasPiO Night Light KickStarter Launches

Today sees the launch of my shiny new KickStarter project, the RasPiO Night Light It uses a passive infrared (PIR) motion sensor to detect the presence of a person and a light-dependent resistor (LDR) to measure light levels. When a person is detected, if it’s dark enough, the RGB LEDs will light to the chosen colour and brightness levels. This provides some transient lighting on-demand. It’s a lot of fun and very useful. Come on over to the KickStarter page and have a look. Here’s the KickStarter Video… Click here to go to the KickStarter […more…]

New RasPiO Portsplus 3 fits all 40-pin Pi - Launch offer FREE + shipping

Shortly after the Raspberry Pi 3B+ came out, I realised that the PoE pins prevent the RasPiO Portsplus from fitting on the GPIO header. Here you go: I had to Dremel the end off to accommodate the PoE pins. I'm not sure if @RasPiTV has plans to amend it. — Raspberry Pi (@Raspberry_Pi) March 28, 2018 So I redesigned it so it now fits on ALL 40-pin Raspberry Pis. The video tells the story… What is Portsplus 3? It’s a small PCB which can slip over the header of a Raspberry Pi so that […more…]

Dremel Table Saw Trimming RasPiO GPIO Rulers

In HackSpace Magazine issue 5, I wrote an article on how to “Make a Dremel Table Saw” This week I took delivery of a new batch of RasPiO GPIO Rulers and in QC checking these, I found that they needed a little bit more processing before release. There was a little ‘spike’ in one corner of pretty much all of them, so this needed removing before these could be shipped. I decided this would be an ideal opportunity to make a video of the Dremel Table Saw in action, so here it is. Enjoy… If […more…]

High Visibility Cycle Lights with Raspberry Pi, ESP8266 & RasPiO InsPiRing - Day 4 Build Log

I’m going to combine days 4 and 5 into one final blog post and video because I want to get it finished and out there. You can find day 1 here, day 2 here and day 3 here. I’m also publishing the code today in a slightly less documented/polished state than I usually do. But it works pretty well. I’ve been using these lights on my bike since Mid September (~6 weeks at the time of posting) and I’m really pleased with them. On the road, cars treat me like another car because I am […more…]

High Visibility Cycle Lights with Raspberry Pi, ESP8266 & RasPiO InsPiRing - Day 3

On day 3 (day 1 here, day 2 here) I wanted to see if I could use a Raspberry Pi (3 or 0W) as the WiFi access point instead of my phone. Knowing I was taking a slight risk (with my time) I flashed a µSD card with the shiny new Raspbian Stretch. I tweaked all the things I normally tweak (e.g. remove Wolfram and LibreOffice, enable SSH, SPI, I2C, camera etc. – I may well add a camera to this at some point WJDK). Then I went through this excellent tutorial here, which I […more…]

High Visibility Cycle Lights with Raspberry Pi, ESP8266 & RasPiO InsPiRing - Day 2

We’ll start with a quick recap of day 1 (which you can find here). By the end of day 1 we had a proof of concept for a phone-controlled, Wemos-driven rear bike light, with indicators (turn signals), tail lights and brake lights. Day 2 started with a bit of real-world testing on the bike. It was determined pretty quickly – within one trip to the gym and back – that mobile phone control was NOT really the way to go. I wasn’t too upset about that because it wasn’t how I originally envisaged things anyway, […more…]

High Visibility Cycle Lights with Raspberry Pi, ESP8266 & RasPiO InsPiRing – Day 1

A few months ago I thought it would be cool to use some of my RasPiO InsPiRing LEDs to make some indicators (turn signals) for my bicycle. But then I got busy completing and shipping the InsPiRing KickStarter, and then went away for the summer. But just as I was coming back, Lorraine Underwood tweeted about her High Visibility Jacket which reminded me of the idea. Obviously I wanted to do it my way and install something permanently on the bike with wireless control. Also I was due to purchase a new bike, which everyone […more…]

Debugging a Tricky LED Problem Using Inspired Logic and a Rigol DS1054z Oscilloscope

Last week I had a bit of a scare. Having tested all 100 of the trial batch of RasPiO InsPiRing straight-8 boards and found 100/100 working perfectly, I issued an update to let the KickStarter backers know. Testing was done with a DigiSpark, which is based on an ATtiny microcontroller. It’s the same device I sent to the manufacturers for their QC testing because it is small, cheap, pretty bullet-proof and I would not have to explain to them how to use a Pi (which would also need a screen, keyboard, mouse etc. thus making […more…]

Make an LED Arrow Sign with RasPiO InsPiRing

One of the interesting usage possibilities for the RasPiO InsPiRing system is illuminated signage. What could be better than flashy, blinky, multi-coloured signage? Well, not much really? So I decided to make an arrow out of two straight 8s and a triangle. I used white depron foam as a base, ordinary headers and jumper wires to connect all the shapes to each other and to the controller. Then a needle and thread and some hot glue to fasten the shapes to the depron. I then darkened the foam with a marker pen. This is what […more…]
