  1. Since this was published at midday UK time I'm taking it that it's not an April Fools prank?
  2. Steve from Railtec is a gent (and I need to get momentum again and actually use the transfers I ordered from him)
  3. Talking of servos and DIY circuitry - I've completed my servo tester: This will mostly assist when installing a servo, to let me confirm that the servo can move whatever it's connected to correctly (usually, point blades) Mini-USB sockets are on order - meanwhile power is connected through the chip's programming header!
  4. I've procrastinated with this servo-testing circuit, which I'll use while mounting the servos that control the points. It's a microcontroller, numeric display, and a knob, plus a connection to plug in a servo. Turn the knob, the servo moves, and the display shows what angle it's positioned at. The microcontroller is an ATMega328P, same as what's in an Arduino Uno and programmed the same way. Now the concept is proven, I'll rebuild it on prototyping board to make something a bit more compact and permanent.
  5. This is really looking the business! Wish they'd just paid some overtime to the p/way dept and got those sidings and loops lengthened...
  6. It will basically be an Arduino - it will have the same microcontroller that sits in an Arduino Uno and be programmed as if it was one. I'm going to write it up!
  7. It will be a gizmo you plug a servo into, and lets you drive the servo do different angles, so I can check I've mounted the servo correctly under the baseboard (or in whatever setup I've installed a servo). Will have a 7-segment display and a rotary encoder to display and set the angle, and be powered by a USB cable.
  8. Very much enjoying the neat wiring! I'm at a tracklaying and wiring stage on my 1200x200mm layout… and that's enough to stall me. Am procrastinating by designing a servo tester instead.
  9. To kind of repeat my earlier replies - I didn't realise it was feasible to make turned brass parts using a dremel (which I own) and a small file (which I have) on a kitchen table (which… I don't have, my flat is too small, but I have a desk). I got back into this hobby when I discovered DCC didn't need to be prohibitively expensive thanks to Arduino base stations running DCC++. Now I want to be scratchbuilding/kitbashing/modifying unique what-if vehicles too!
  10. That just looks fantastic! What I'd really like to know is, if BR was capable of commissioning trains like this in the late 50s… why on earth did so many areas end up with EPB-derivative slam-door compartment stock instead?
  11. Child of(/in) the 90s here - so for me it was 081 811 81 81, and later 0₁81 811 81 81, which didn't quite scan
  12. In electronics, a closed switch is on and an open switch is off - because there's an open gap between the contacts… the "normally closed" terminal will be "normally on" unless something pushes the switch! Painful lesson to learn, though...
