Home Brewing Beer with Tech
Many moons ago, I used to brew my own beer. Nothing spectacular just a 25l fermentation bucket with a ready made kit. Since we moved house I’ve always had the plan of hiving off a section of the garage dedicated to beer making, the problem with that is my garage has literally been full of stuff. Now that most of the renovation projects are complete (nearly 5 years later) there’s room in the garage and I can now start brewing again.
Sensoring Aquaponics
As part of my interest in aquaponics I’ve always intended to enable some kind of electronic monitoring, various thoughts on what to monitor and how have been in my head for a while. Recently I’ve been wondering if the temperature levels of the water are high enough so this was as good a place as any to start.
An Arduino was my obvious choice to start with, I built various circuits but soon decided that I wouldn’t be running Ethernet anywhere near and that kind of ruled it out with regards to re-using existing kit. I decided to use one of the nodeMCU devices I’m halfway through a project on (I’ll just buy another couple eventually).
Arduino based Electricity monitor
Over the past 12 months or so I’ve been looking to add various “Smart House” components to my home, rather than do this in the traditional sense of buying something off-the-shelf I’ve been experimenting and building my own. One of the real plus points in me doing this is that all the data that is passed around is in an open standard and format chosen by me, not some cludge to try and extract information in a format decided by a-n-other manufacturer.
Light control with MQTT on Arduino
It’s been a while since I stayed up most of the night writing code, mainly down to having a young daughter but also down to the fact I haven’t found anything that needed a late night hack session to produce a result. This weekend changed all that, I’ve been playing around with home automation for a while but am now actually taking the plunge. I purchased a load of Arduino and electronics kit over the last few days to start prototyping the setup.
New projects: Pi's and Arduinos
Recently I’ve been working on several new projects, all of which use either a Raspberry Pi or an Arduino.
Site-To-Site VPN
A friend of mine recently opened a new satellite office, and as part of his day to day work had a requirement to connect the two together so resources on either side could see each other. Site-to-site VPN I thought, and what better kit for the task than a couple of Raspberry Pi’s. Nice and small so they can be kept along side the routers. Each site had a simple ADSL broadband link, with a couple of PC’s connecting up.
