  • Arduino, RS485, mixed powers and multiple devices - As mentioned previously  you need to be very careful when using multiple sources of power that are coupled by a common rail – nasty things can happen which will ruin your day (as well let all the critical magic smoke out). Luckily for me my power supplies are able to work well together and not fry[...]
  • Arduino and multiple power sources – things to watch out for… - As I mentioned previously , I had a need to double check that the 5v USB supply from my laptop was floating with respect to my lab power supply. I measured a no load difference on the 0v lines of around 120v – which raised the obvious concern that if I connected these two 0v[...]
  • Propel, custom Behaviors, Composer and Git – how to get it all working - After having spent a bit of time trying to work out how to get Propel and Composer to play nicely together, I thought it would be helpful to write up a little aid for those going through similar pains… The end game is to have your custom behaviors ‘live’ in their own Git repo to[...]
  • Arduino Uno clone RS485 network - At home I have a need to measure temperature and control various circuits in response to those temperature changes and other inputs. The sensor network needed to span at least 100m and ideally should have the ability to reach out to 200m (so I could get down to the Chicken Coop and pool). Looking around[...]
  • STEM, AI and the future - One thing is very clear, the future is going all STEM… According to various articles, it appears we are heading for a future full of robots and technology that will drastically increase the degree of automation as part of the economic and manufacturing process. I think this is largely inevitable as there are a few[...]
