Easter and nothing happened!

Well Easter arrived and with it family commitments, BBQs, beer, wine, cheese and chocolate ;-)

As a result nothing happened on any of the Easter evenings. The week prior to Easter I continued with the little Metcalfe shelter and placed a small SMD LED with appropriate orange tinting inside before putting on the roof. So nearly finished this one. As for the Dapol shop, hopefully this week I can sort out the internal lighting and the base.

As for the Pi experimentation, I've decided I must commit myself to at least one night a week to keep this going else it will never get finished.

Let me see how this week goes?

Another building on the go

A bit late with this update. Last week I progressed with the Dapol shop and it is looking really good. I decided not to put a floor in and will need to position the lighting in another way. Also have to put the base on. All nearing completion and a photo or two will follow once done.

My mate PK also dropped off a free Metcalfe kit he received in Railway Modeller that he didn't want. It is a small platform shelter. I've never built a Metcalfe kit before but have wanted to. This is small enough to give me a feel for the quality of the kit. I have done Superquick cardboard kits previously and found them a bit on the thin and fiddly side. So on the weekend I started this little kit and it is pretty good to construct. As usual I will put a small light in side (one of those SMD LEDs I got for the signals). I intend to use this as a bus stop opposite Kensington Hill station as the brickwork will blend in. Once again once finished I will put some photos up.

Easter is coming up so maybe I will get some time at night to finish these off this week, but time will tell.

The Shop continues

So this week I was able to progress with the Dapol shop. I'm taking my time with this as I will be modifying the basic kit to accomodate the usual lighting. I also have to put in a floor to separate the upstairs and downstairs for the lighting I intend to put in. This is the first kit in about 30 years (since I was a young teenager) that I have done by painting on the sprue before putting it together as there are a few detailed features that need to be painted separately. I will also put it on a base that fits in with the general features of the nearby buildings. I will also use some curtains from a Scalescenes kit to spruce up the rather bland 'out of the box' features of the windows. I am having fun putting this rather simple structure together to make it look just right.

This week will be continuing with the Shop I think as I am just not in the right frame of mind to stuff around with the Pi and its integration with JMRI, NCE and MERG. All in good time!

Nothing this week

Hi to all my ardent followers. As mentioned in my last post Dear Ole' Dad passed away last weekend so this week has been busy sorting out the arrangements, etc so no time for modelling as it has been a pretty emotional week all round.

Perhaps I'll continue with the Dapol shop this week. Stay tuned.

A shop is started

As expected the week was a shambles modelling wise. However Saturday rocked up and it was wet. So I went rummaging around the kits drawer and dug out a Dapol General Store kit and started cleaning the flash off it and started some painting on the sprue as it would be easier to do it on the sprue rather than when installed. These were left over night to dry. These will be the project for this week if I get time.

No Pi work unfortunately.

And on a personal note, my Dad passed away unexpectedly during Saturday night, he will be missed by all who knew him. I already am;-(

Note to Self - Remember the resistor!

In between other duties I managed to put together the circuit described in the MERG journal but it didn't quite work correctly. As I did it on a breadboard instead of the stripboard as I wanted a temporary setup, possibly there was an incorrect wiring. Any way while I was mucking around with this I thought about checking the semaphore lamp after I had painted it black (as per quite a few prototype photos I found on the Net) to reduce the 'through plastic' brightness. I quickly wired up the 9V battery and the lamp glowed pretty brightly. A bit TOO brightly before dimming rapidly. What just happened I thought? Then it dawned on me, the RESISTOR! I forgot the resistor hence the extreme lighting. Damn! However it didn't completely stuff up the LED and there was a dim glow once I put a low resistor (68ohms) on the +ve wire. Not to worry as this was the experimental kit. I can always position the semaphore so that the lamp isn't seen.

Today I decided to connect the servo up to the MERG CBUS servo controller to see if it would work. Yep it did. With a bit of fine tuning with the help of the control software I think it works very well. I also connected up the lamp (with a resistor this time!) to video the movement with illumination. Below is the video.

This week not sure what I will do. Maybe get back to the Raspberry Pi as it has been nearly 3 months since I last mucked around with it (just before Christmas last year in fact!)

Semaphore done..Now to automate

This week I was only able to finalise the semaphore. This entailed mostly painting in the wires. Today I bodgied up a jig from some ply offcuts for putting the semaphore in as well as holding the servo to automate the arm.

Below are the photos promised in the last post as well as what has been done this week.

This week I will probably only be doing the automation. Instead of the MERG module to automate, I might bung up on the breadboard a servo controller articulated in the latest MERG newsletter to see how it goes. If it doesn't the MERG module will be Plan B!

I could have used a smaller diameter drill in hindsight.
