Steve’s been busy with his 4×8 model railroad layouts – this one has a wild west theme.
“This is my first layout(4×8) and with only limited space I created a western town from the late 1800’s.
With over 150 trees (75% hand made) and (25% gifts from family) two oval tracks.
Now on to Dean, with the next part in his series:
(If you missed his last post, it’s here.)
“Hi, Al, I’m digressing a little from my Scenic Ridge construction with this short video on a cheap and reliable power supply I use to drive switches (turnouts).
This video describes a capacitive-discharge power supply that I use to power my Atlas switches on my Scenic Ridge Railroad under construction.
It can also be used with other twin-coil or snap switches such as those manufactured by Bachmann or Peko.
It is easy to build and uses an inexpensive Wall-Wart (wall plug-in) power supply, which you might have on hand. Anything you have rated at 12-18 volts, ½ Amp or greater, should work.
Generally, the positive lead on the Wal-Wart is the internal wire. Or it might be the wire that is painted white. Check before you use it since it must be connected to the correct lead on the capacitor or the capacitor will self-destruct.
Here’s a list of parts. Unfortunately, you have to buy several of the smaller pieces at a time. Shop around to get better prices or find some friends to share the cost with.
• PLUSPOE 12V1A AC DC Switching Power Supply Adapter 12W Wall Wart Transformer (on Amazon $6.98).
• 10 Pcs 5x7cm (2x3in) DIY PCB Prototyping Perf Circuit Boards Breadboards US (on eBay, 10 for $4.95
• 100 ohm 1- watt resistor (on eBay, 10 for $2.99)
• 5pcs 35v 4700uf 35volt 4700mfd 105c aluminum capacitor 16×30mm (on eBay, 5 for $5.49)
A big thanks to Steve and Dean.
Steve looks like he’s having fun on his 4×8 model railroad layouts.
