Remote Folding Mirrors

[micromarc]

I m looking for someone that has fitted these. Got a few questions about what i need for the job. I understand the splicing\wiring in part its the control box that i m not so sure about.

LINKY

Thats the link there.

Anyone good with electronics might be able to help.

[Geoffers]

I know a little bit about these. What's up?

[micromarc]

What's up?

Just the person really.

The bit thats really got me is the control box, can i buy something from maplin and add a few wires and away i go or do i need to build something? Adding the switches, relay and pulse timer?

[Geoffers]

None that I know of mate - you're going to have to build it I'm afraid.

There's a couple of people on here who have found a virtually complete timer but that was a while ago.

[sparkystav]

Maplin, thats where i got mine from but i cant remember the part number.

Do a search Marc, theres a load of threads on this and prob the part number in there.

i tried maplin but couldnt find one..

all the ones i looked at were no good..

Sorry for askin so many questions.

Would this do the job on its own or would i still need to add a resistor in?

[redz_UK]

tried that one!!

geoffers said it wouldnt work but cant remember why!!

[micromarc]

http://www.maplin.co.uk/Module.aspx?ModuleNo=2707

So one of them and one of these?

http://www.maplin.co.uk/module.aspx?moduleno=2536

with the 8 pins?

[micromarc]

reading through a post from what i can work out this is the correct timer? Just need conformation from someone and also if that is the correct resistor?

[Geoffers]

Nope - I'm afraid those timers won't work. Actually, yes they could if you were to modify them.

This is because they rely on the timer starting when power is applied. There is nothing to apply the power because the alarm on signal only gives out a few mA. Therefore it needs its own power and uses the alarm PULSE to start the timing.

You can adjust these and add the additional input circuitry to pin 2 but to do that you would also need the output relay as most are single pole. The mirrors need changeover. For all the hassle, it would be easier and cheaper building one from scratch.

You are looking for a timer that has selectable input trigger.

Yes but you'll need the rest of the components as well. Also, the relay you have listed is just the relay socket, not the relay itself.

I'm sure if you went into Maplins with the parts list off the project they would sort them all for you. Its not that critical really so equivalents would be ok.

if it helps i think i still have my recipt from maplins with all the part numbers to build the closure circuit it only took me about 20min to build and does exactly what you need it to do

PLUS

it allows you to add functions to the circuit after for example total closure, or maybe walk home lights all of which are very easy to do once you have this kit built

here are the maplin codes

fl17 - stripbord

n31aw - 5a dpdt relay

m10k - resistor 10k

m3k3 - resistor 3k3

m1k - resistor 1k

m4k7 - resistor 4k7

m100k - resistor 100k

fw26 - 220k potentiometer

ra49 - cap 0.1uf

qq14 - bc547c

ql73 - in4001s

ql80 - 1n4148

vh38 - cap 100uf

and a 555 timer i had some of these spare so didnt order one but they will know whatyou mean unless there stupid lol

[micromarc]

So iif i go to maplin and ask for

Switch

Suitable box

Wire (16/02)

Pulse Timer Module

DPCO Relay

Fuse Holder + 1A Fuse

Get some connectors, heat wrap and the 2 diff wires i should be good dont need any specifics on the parts at all?

Yes please mate that would be great.

[Rabster]

the list of parts are to go with geoffers mirror circuit project

[micromarc]

Nice one is that everything i need or is there anything else?

[DJ Wozza]

So which bits are need for you to fix mine then Rabster ?

ql73 - in4001s

or

ql80 - 1n4148 ?

(funny story to go with my module and its misbehaviour )

[Geoffers]

1n4148. I would swap the .1uf (C1) cap on the input side too. Also, check R2 isn't shorted on the board.

There's a spike getting through there :winky:

it doesnt need fixing its a design feature

[micromarc]

Final question i hope,

On the diagram it has C1,2,4 as 100nf.

Is that a ra49-cap 0.1uf or a vh38-cap100uf.

I think its gonna be the ra49 can someone just clarify this for me

[Geoffers]

You are correct - RA49 (or use the decoupling BX03D)

.1uf is 100nf

when did we start speaking klingon??

all gone over my head now!!!

[aido]

all gone over my head now!!!

This should help those of us who are confused:

:D

[micromarc]

Cool well here s hopimg i ll be able to get all the goodies tomorrow and then the fun starts :D

[Geoffers]

Keep us informed Marc.

@ Aido - we've seen enough of your Klingons over the years mate :lol:
