This weekend we should have been seeing friends but unfortunately this didn’t happen (I missed out on BeerTownMalton and the NCB meeting in Sowerby Bridge too ) so …
I made a bit more progress on the HERMS panel. The LV side is nearly complete.

For Power I used a reclaimed WII PSU 12v @3.7Aand a 12-5 v step down board with USB ports to power the Raspberry Pi and the spark shield, I need two more heatsinks after my failed attempts at using an old CPU heatsinks…


and I need to get some more DS18B20 probes. The previous batch from an Amazon supplier ‘Tenflyer’ just don’t Work. ! so either its’ a faulty batch ..or… their wire colour code is wrong ! so thats 5 x RJ45 connectors wasted… I even went so far as to chop the RJ45 off one and splice in a known working probe from another supplier, all to check the RJ45 was crimped ok.. it was…!

So Now to decide on HV outputs and switches and protection…. !
Do I go with wires tails from the box bottom or go 16A CEE and switches in the Door Panel ?
or a combined interlocked 16A CEE
decisions, decisions …
My PartiGyle brews are coming along and will be swapping into secondaries soon. did notice some odd swinging from the new @BrewPi spark thats now on the fermentation fridge so I have just updated the firmware to 0.4.3 hopefully it will settle down.
