This week I was very slack and forgot to keep track of my various modelling activities. On Monday I got an SOS call from Barnacle Bob and installing LED lights into his 1900 Class QR Railmotor. We had previously worked on a process to build a chassis made from styrene to install his 12mm bogies into. Bob had drilled out the various headlight and marker light holes in the railmotor shell and needed some help to wire up the LEDs. We made arrangements to catch up on Friday at his place to check it out. On Friday I explained parallel and series and we worked together install the two 0402 white LED headlights in series, the two 0402 white markers in series and the two 0402 red LED markers in series but in the reverse configuration to the white markers so only one came on when power was applied. So these three pairs were wired in parallel. We then built up the other end’s lights in the same manner and then joined both ends up. So when the headlights and markers came on at one end, the red markers came on at the other end and the opposite happened when we reversed the polarity to the lighting infrastructure. I think Bob was happy by the end of the work session. These still had not been connected to the power pickups by worked off a 9V battery,
Earlier in the week a few of the Tuesday Nighters group were online on Tuesday night and had a good time. One activity I did do in the shed was find all the items and tools I needed to take to the working bee on Saturday. The cricket on TV sort of distracted me from a lot of other activities. That is finished now, so I might have time for more modelling activities next week.
On Saturday I met up with a few other Div 1 workers and we continued to work on the modules for the Div 1 Freemo layout. So we did some plastering, added scatter, some greenery, and then some fencing. We also made our own split post fencing from kebab skewers and other 2.5mm pieces of dowel from a $2 shop that we cut up and them split them into individual fence posts. These were then stained. I think everyone there was working on the install of these fence posts. Basically the comments being generated were about people learning new skills in the scenicing of the modules, so this was a great positive outcome. Late on Saturday night, we again gate crashed the British Regions Brew and Natter. Gordy forbade us from talking about the cricket. Well I complied with this edict until I left the chat and posted a comment in the chat. Hehehehe!
Another week has gone past, and I did not get to go to the shed to work on the Sunnybank Extension and the various track wiring in this area. Perhaps this coming week. I did however spend some time trying to get a piece of electronics that I picked up at Bob’s (a different Bob) on the previous Sunday, to work. I could not get it to talk through its I2C protocol to light LEDs. So I will have to wait until some more are delivered by mail (hopefully) this week. The general consensus was that It might have been damaged or had a problem which was why it was lying about at Bob's. I also have some other pieces of electronics also turning up this week. These are needed for the new exhibition layout control panel and the layout.
