So we’ve been having difficulty getting the underwater fish cam streaming reliably – and now that there is a higher-powered Pi around I thought that I’d try upgrading the basestation of our Aquaponics control system to see if the extra ooomph helps. But of course, there are new problems – such as our old way of […]

ESP8266 modules hardware guide – gotta catch ’em all!
OK so there is this new(ish) chip the ESP8266EX that promises a full wifi stack and a mcu all for £2-3. But the chip on it’s own isn’t so useful – so most of the excitement has been around the various modules made with the chip, some memory and an antenna or connector for one. […]
Read More…thethingbox.io image – testing and extending
I’ve started investigating the http://thethingbox.io/ image – they say ‘Just download and write a Raspberry-Pi binary file on a SD card to get it ready!’ Well, that’s mostly true – but I found a few issues once I logged on to it via ssh that I’ve documented here, mostly easy to fix once you know how. […]
Read More…Open aquaponics API, documented with Swagger and sample app
We’re proud to release the first public iteration of our Aquaponics Open Data API. You can see it live here – and we are very keen to get feedback, suggestions, improvements and collaborators in true open-source fashion. Our goal is to allow others to write applications to use data from our systems for their own purposes, as well as reusing […]
Read More…Wireless pH sensor
JeeNode + MinipH + LiPo + Case = Wireless pH sensor This sensor is probably the one I’m most proud of so far, all the elements came together really well despite having to hack the MinipH circuit in the literal sense! The enclosure maketh the project As soon as I had finished making this sensor, […]
Read More…Node-Red on Raspberry Pi with RFM12B support
You can find these rfm12b modules on sale on ebay – I paid about £10 with delivery and it arrived promptly, the seller chacal_zoom seems to have a number of interesting little circuits, specialising in minimum parts and tiny boards! (avoid the bedini circuit tho he he he!!!) After seemingly endless weird problems getting the […]
Read More…RFM12B linking a JeeNode Micro with a Raspberry Pi
I’m going to try to use my new RFM12B based JeeNode Micro from JeeLabs to talk to a Raspberry Pi equipped with another RFM12B. Although the radio module (and JeeNode) are from JeeLabs, I’m going to connect it to a raspberry pi using an Eve-alpha board I got via the Ciseco kickstarter a while back. […]
Read More…Command line control of arduino using ino
As we’re going to be programming the arduino via the raspberry pi over ssh, we need a command line tool to talk to the arduino. Luckilly several such ways exist, including make-files from several sources. I chose to use a tool called ino which seems to have packaged up the toolchain in a fairly decent […]
Read More…Setting up a Pi from bare Raspbian to work as a Node-Red controller
Here is a set of instructions to go from bare Raspbian to work as a Node-Red controller and also send text (sms) alerts using a 3G usb dongle. For various reasons I’ve needed to retrace my steps a few times, so here I’ll document them all for my and your convenience. Starting point is a […]
Read More…raspberry pi running node-red, wiring-pi to pwm control a light
OK so putting node-RED on the raspberry pi was almost as easy as getting it onto my computer – see previous post here. I started with the occidentalis distro from adafruit – and to install node.js itself I needed to use different package to match the pi wget http://node-arm.herokuapp.com/node_latest_armhf.deb sudo dpkg -i node_latest_armhf.deb but apart […]
