Re: what switches for mimic board

Don't know about the Hornby surface mount motors but most solenoid motors that I have come across seem to move with considerable oomph cannot see how they would not manage to activate any micro switch.

Re: LED wiring on mimic panel

Quick question. Can I use a variable resistor like a dimmer switch for the whole panel so I can set the brightness? Just a thought Thanks Dan Not advisable if you turn the resistance down too low you will end up with a lot of popping LEDs. As advised previously use individual resistors to current l...

Re: new idea for long range photo detectors in non-scenic ar

One way round ambient light problems is to send a coded signal. Some time ago I was involved in building a small IR robot buggy, this was controlled with a TV remote using the Sony protocol. It was tested outside in bright sunshine and still responded to the TV remote over several metres.

Re: DCC interference?

If the interference only occurs when locos are running but not when the DCC system is on then it sounds very much like the locos. Using twisted pair cables should help and make sure you have decoupling capacitors fitted as close to the power pins on the PICAXE, 100nF should be Ok.

Re: DCC accessory control

Perhaps the most important factor when it comes to using DCC to control points and signals is how simple is the operation of your DCC controller. I do not know about your Hornby controller, but my Lenz system is a PITA due to the number of key presses it takes to switch from loco control to accessor...

Re: Making a single gate move. HELP!

By far the most simple solution is a £1.50 PIC, a handful of resistors, a couple of capacitors and a servo. No need for any limit switches gearing or anything else. The PIC can accurately turn the servo and hold it there in the same position each time. The only input required is from the changeover ...

Re: Lighting BUS Wire Thoughts

Seems quite a normal thing to do, however do watch the likely current draw ie. 100 LEDs @ 10mA will draw 1A in total and if using filament bulbs the current draw will be considerably more. So install wires capable of carrying the anticipated current with some overhead for possible future expansion. ...

Re: Miniature saw table

I am thinking of embarking on a new project which is going to want a few straight and bevelled edge cuts on ply or mdf up to about 6mm thick. We are talking about something about four feet long by six inches wide. It is going to be a body for a five inch gauge battery powered loco once I have thoug...

Re: 555 timer project help - updated

Thanks for the info Richard. Will it work as shown in the video? I have already bought all the kit as shown. I understand that I'll have to be careful mating and removing the chips. I will hopefully only have 6 or 8 to do in total. I am also going to use the program map directly copied from the vid...

Re: 555 timer project help - updated

Hi everyone, So after some digging around for PICAXE stuff (thanks for the tip Richard) I came across one of my favourite YouTube layouts, Everard Junction. He made some signalling modules using PICAXE. It was in one of his 'how to' videos. I watched it and thought it seemed pretty straight forward...

Dan

Have a look at PICAXE their basic PICAXE 08M will easily do what you require, programming software is all free the only additional hardware required is a download lead.

Re: Layout/storage advice

The conservatory is a definite no no. The heat and bleaching effect of the sun will play havoc on any sunny day even in the middle of winter. Our grandson has left the odd toy out on the window cill and the colour has bleached out, oddly Lego seems quite stable. Our conservatory does not get as cold...

Richard, you are obviously stateside.

Re: Consumer legal position

The principal of return our mistaken item before we will send you the thing you paid for in the first place shows a distrust of the customer yet firms expect consumers to part with money first on the promise they will supply the goods. I think when a mistake like this is made it is the duty of the s...
