Re: Am i doing this LED work correct?

Sorry, yes, I meant Schottky
DCC is not a fixed frequency, it varies dependant on the signals being sent! Technically it could be from 10kHz to 17Khz or anywhere in between, at any given segment in time, I was rounding up to simplify.

Re: Am i doing this LED work correct?

I may be scaremongering here, as you may NOT have a problem, but technically, you should use a fast recovery diode network (bridge rectifier) or commonly known as Schottky 1 diode. Normal diodes are only designed for (50Hz) 'mains' frequency, but DCC is in the region of 20,000hz (20KHZ) and normal d...

I am branching out (pun intended :roll: ) into video versions of my webpage "How to's" :wink: With a new found confidence in the output of my new super camera and some tripod/clamp/bencharmyajigs, I have documented one of my more graphical methods of tips - How To make removable loads (sem...

Re: Frontington & Backwoods Railway

You could scratchbuild your own stairs from styrene, but if that sounds too ambitious, try Plastruct, they make the stairs STA-6 and the handrails SR-4 http://www.plastruct.com/catalog/Vol_10_CatalogSMFL.pdf Given the cost of these two packets, it may be cheaper to just buy a new Dapol signal box ki...

To be honest, your the first to ask how I got my handle! My father was famed for chopping tree's down and would shout "Timber" as it fell, following in his footsteps as a Boy Scout leader, I took the nickname on. With the advent of an interest in amateur radio, I used the same name and fin...

Re: Am i doing this LED work correct?

Good point Rob, a 50 to 200 ohm resister can be fitted in the supply to limit capacitor charge inrush.

Re: Am i doing this LED work correct?

This is a pet subject of mine. One that I have not cracked the ultimate circuit for! (as yet) What DCC are you using? (determines the voltage it puts out). The LED strips have current limiting resistors (or current limiters), if the voltage is excessive you could use an LM7812 (100mA) or a voltage P...

I am sold on dust covers, especially in dusty lofts and garages. Great job, just find a blue sheet and you have a sky!

Re: Lumsdonia

Having taken some rubbish video at the Wigan exhibition the other week, I decided to by a better camera, a superdooper DSLR :o One of the cool features is stop motion, so as ever, game to try anything, have a peek at my first attempt ! It's set on part of a 600mm x 400mm diorama I am building (an ex...

Re: Great Electric Train Show - 13th-14th October 2018

I went on Saturday and enjoyed the show, its the first one of that size i have been to, it was really really busy and got rather hot but some really nice layouts on display and worth the trip. I gave up trying to take photos about 1/3 of the way in as it was just to busy but thought i would share t...

Re: The Great Model Railway Challenge

Any publicity is good publicity - there is no such thing as bad publicity ​ The hobby does not exist in the media, I don't remember ever seeing a model railway show on the telly! It is better that we receive (potentially seen as) bad publicity, than no publicity at all! At the end of the day, it's e...
