Hi Martin,
"I suppose I should get up to date and do things properly."

Judging by your results with Cottesmore you can't get much more 'proper' than that!!👍

Shame that I don't like yoghurt 😝🤔

Just like 'real life' conversations Red 😉
An old 13A plug (useless over here!) saved my bacon last year when I lost a 5BA nut from my Taycol Target while renovating it. Try buying brass BA nuts in Germany🤔
After much scratching about I discovered that the wire clamp nuts in the plug are a perfect fit, even better they don't need a spanner 😊

Glad to see that we 'boaters' are doing our bit for the environment 👍

Join the club - have all sorts of gears from clocks & printers etc , motors from hairdryers and old printers (new ones tend to have steppers), both round and square brass old electric plug prongs (very useful), 1000 odd 1/4" long brass rivets from a waste bin, wood from fruit boxes including some nice ply, planking strips cut from discarded pallets , some short mahogany planks from a wrecked Air Sea Rescue boat at Cape Point (the vandals at Cape Parks burnt the wreck which could have been salvaged by a friend who collects full size boats)), and a lot of roller type micro switches also from the bin.

Isn't it funny the way threads wander off the original topic

Hi Martin,
There's a saying over here amongst ship model builders, which translated means
"Ship modellers will collect and save anything that won't start to stink after a few days!"😉

I do the same as you with old video recorders, PCs, dead garden solar lamps etc etc.
Great sources for motors, LEDs, power supplies, fans, connectors, ribbon cables, cogs n pulleys .....
I also browse around the flea markets here; great sources for odd bits n pieces.
Have found boxes of assorted cog wheels and pulleys, once even a whole tray of miniature 5V relays. Which I used for a home made controllable switchboard in my destroyer. See pics!
Carry on recycling👍 Cheers, Doug

Hi Guys,
Thank you for the LED calculators it is much appreciated.
Being an old guy and doing things on a zero budget is a bit of a challenge,I tend to use whatever I can get my hands on.
I selvage old broken electrical stuff for the parts to use on my models, and recycle plastic food containers for usable plastic.
I tend to look at all sort of things and think to myself what can I use that for.
It is surprising what you can make from junk!
I suppose I should get up to date and do things properly.
Thanks again Guys.

Martin.

Hi All,
I would recommend this one
http://ledcalculator.net/
Gives more useful straightforward info, incl. wiring and cct diagrams and useful links for the electronics novice, and without all the ballast of the nonsense and abusive comments!
Happy LEDing 😉
Cheers, Doug 😎

there are any number of 'led resistor calculators' on the web. Google one, then fill in your voltage,etc and it will tell you what resistor you need... I'll start you with one...

Hi Hillro,
Well I am not an electronics expert and it was just an experiment.
I had a few LED's of different colours knocking around so I just linked them up in parallel.
Unfortunately I have a habit of doing things just to see what happens.
I used one red and one green LED and a variable resistor and it worked fine.
You are supposed to use ohms law to work out the required resistance but I just try it if it works great of not try something else.
If I only had the exact amount of LED's then I would do it properly.
I hope this helps.

Hi Martin.
The idea seems to reduce problems with supplies for LEDs
However ,how have you handled the differences in voltages required for different colours.
Regards
Robert
