Years ago I made an illuminated house number. I soldered hundreds of little LEDs across busbars. I might have posted pictures here at the time. Anyway I decided I want an illuminated number on the new postbox (made necessary by the gate), but this time I would take advantage of the availability of LED panels. I used a 300 x 300 one because I couldn't find a smaller square one. I cut the number out of an aluminium panel (the side panel of an old PC). I tried to get someone to cut it out with a laser machine but only one replied and they wanted stupid money so I did it with a Dremel. It's a bit rough but no-one will notice. The aluminium is fixed to a sheet of 2mm white perspex. The whole thing will be behind a clear perspex window.
The reason I have large illuminated house numbers is because there are idiots on this (long winding dark) road who insist on giving the house name rather than the number to the non-English speaking delivery boys who come out from the fast food establishments. When some hapless Slovakian bothers me at an ungodly hour to ask if this is 'Niceouse' or 'Costaplenty' I can simply point at the number and "No it bloody well isn't, so f*ck off."
These intrusions were one reason for getting the gate. The other was the constant stream of 'unexpected visitors'.
The bird sits on the wire across the road most days.
