The Red Hot Chilli Shed

Monthly update 01/10/2020I have not made many changes at all this month, the shed was working well apart from one issue where the NodeMCU would get get stuck in an  loop now and again, this would only happen if it was left running for more than a week, I think it may be due to a memory leak in the programming filling up the spare memory over time.I have now fitted a digital timer plug to the power supply for the NodeMCU and it will restart the system every 24 hours. This month I was extremely happy to see Rambo has at last started to produce some chilli fruit, I first thought the flower was dying as the petals started…

Monthly update 01/09/2020My Odroid N2 4GB arrived this month to replace the raspberry pi 3 that was running MQTT and Node Red for the chilli shed.Its is more expensive than the Raspberry Pi 4 but good grief its a fast bit of kit. The main CPU of the N2 is based on big.Little architecture which integrates a quad-core ARM Cortex-A73 CPU cluster and a dual core Cortex-A53 cluster with a new generation Mali-G52 GPU.It only took an hour to move all the software needed onto the Ondroids 16GB eMMC  and boot it up.I have relocated the setup to the living room of the house and my intention is to have a small monitor attached to it that displays the gauges…

Monthly update 01/08/2020Well, a lot has happened this month.Firstly, I made another big mistake this month, the mistake I made was the incorrect ratio of liquid fertiliser to water I mixed together.I miscalculated the ratio of liquid fertiliser to water and caused some damage to the chillis.The symptoms started showing a few days after I had used the fertiliser mix, the chilli plants first started to wilt a little more than normal at night,  then some discolouration appeared on the leaves a couple of days later, the discolouration got quite bad before I realised my mistake and rectified the issue. It was a friend, Richard Mount that provided me with a link to a website that helped me to spot…

Monthly update 28/06/2020I am starting to believe I have the settings dialled in perfectly on the control system.My chilli plants are growing fast and looking great.There is still an ongoing issue with high temperatures during really hot days even in England.I think the only way to rectify this maybe to look into putting in automatic vents in the roof swell as having the automated window opener.I have ordered some serious 12V blower fans that will hopefully be able to pull in more cooler air from outside, they should be arriving in the next few weeks, so they may help with the heat.The new watering system is showing no signs of Algae in the water container, and the system is only watering…

Automatic window openerAlthough I live in England the inside of the shed is still getting to hot.Up until now I have been manually opening the windows on the shed to let a little air in.Thats is just too much effort for a lazy gardener like myself.Looking online I found what I needed.The window opener is quite a simple device but works great, its a large hinge fitted with a piston filled with wax.When the wax heats up the it expands and moves the piston which opens the window.The version I have has a nut you can use to adjust the temperature at which it will start opening the window.They are designed for glass greenhouses but with a little inginuety  I…
