Can you believe it is already halfway through the month of October? Time for an update!

Christmas decorations and lights have now been installed in the three front windows. The window borders will be installed during the next week.

Where the majority of time has gone is setting up the new DC controllers. The controllers themselves appear to be working perfectly out of the box but where the issues have been is with a dodgy power supply unit (DC Controllers must be connected to a PSU and not directly wired to 240v AC).

I opted to purchase a non-brand name power supply, due to hearing that other Christmas displays were using them without issue. However when I powered up my PSU, older computer monitors using VGA cables started showing strange lines and the ADSL2+ modem lost connection to the internet. Turns out this particular cheap supply from China emits high electromagnetic interference in the air (EMI). Cheap fixes such as ferrite rings and filters proved no good.

I will now be using official Meanwell power supplies even though they cost anywhere from $100 upwards as they do not let off any noticable interference and also come with a reliable warranty.

Lesson learnt.
