[Soldering buttons question (OMRON B3F with B3J question).]

There is a switch symbol in the picture labelled "Terminal Arrangement/Internal Connections (Top View)"

quote from: http://www.kpsec.freeuk.com/symbol.htm

this also shows pins 1 and 2 are connected, pins 3 and 4 are connected.

So the switch is electrically connected between either pins 1 or 2 ... AND ... either pins 3 or 4.

You then wire this switch up the same way as the push button switch symbol:

you would see here:

Thus connect pins 1 or 2 to ground, pins 3 or 4 to the DIN input.

Thanks for the explanation Wilba.

I guess I need to read up on the different symbols :-)

Hi

lol, look in the right corner below of the picture, there is the pin-description....and as its said, pin1+2 and 3+4 is connected together, so you have the choice, connect pin1 to GND and 3 to DIN, or 2->GND and 4->DIN ;)

EDIT : Or 1->GND....4->DIN    or    2->GND....3->DIN.....  ;D  ;D

Hi MTE. You're my new best friend.

I don't see what you're referring too as detailed as you are but I am just an amateur.

Thanks.

To the soldering iron !!

[Soldering buttons question (OMRON B3F with B3J question).]

Hi members :-)

I finally got my MIDIbox up and running with all the pots, so now it is time to move on to the buttons and the DIN/DOUT.

I bought some OMRON B3F/B3J tactile buttons with (as far as I can see) four connectors labeled 1, 2, 3 and 4 and two connectors for the LED.

This is the one:

I can't seem to find any connection information anywhere on the OMRON site, and google didn't help much either.

Any of you have had any experience with these buttons that could tell me where the 1-4 connectors should be connected to my DIN ?

Thanks in advance and for all your help;

[I am finally building it.]

yeah man, good luck - we should get together and share parts ;) hehe.

Any idea on how to case it yet?

No but I have a couple of ideas.

My first choice was to have a frontplate made from Schaeffer and I still might, but initially I'll have to wrap it into something else to make sure my skills are good enough to make it work at all. Paying 100 - 200 € for a nice frontpanel that'll never get anything plugged in is not my kind of fun :-)

So I was actually considering a Retex Abox-5 (http://www.retex.es/images/cajas/Plastico/abox5_pe.jpg) but I am not sure yet. I'll have to finish most of the soldering / building before making any final decisions.

And yes; we SHOULD get together and share parts .. when the Alltronics package arrives maybe ? :-)

Have a great weekend while I try to get my LCD display to work;

Hi guys.

I am finally starting to build my MIDIbox.

I decided to make a webpage for it so those of you interested can follow along.

Here's the URL to the site. Feel free to drop by now and then !

[What exactly is the jumpers I need to solder on ? Core related.]

A thin isolated wire or cable (what you call it). For the short one you could also use the the part you cut off an recistor the you mount it.

good luck

Thanks a lot JS. That's what I thought, but I thought I'd better ask before doing something stupid !

Thanks again;

[What exactly is the jumpers I need to solder on ? Core related.]

Hi guys.

Yes; I am a newbie, and I am having some worries regarding the CORE board I bought from SmashTV recently.

It says on SmashTV's site that I first have to install / solder the jumpers. What exactly do I need to connect these holes ? Am I supposed to use any of the supplied components ? Am I supposed to use an old piece of cable ? Any advice ?

I KNOW it's an easy question to answer for you guys, but I am really puzzled by this.

So basically:

With what do I / can I connect the jumpers (marked in RED here):

Thanks in advance;

Jeg har sendt dig en mail :-)

Sorry for the danish guys !!

[Switches with built in LEDs ?]

Hey !

Tak for svaret / Thanks for the replies.

I have been looking at mec.dk before I asked the question in here but they LOOKED expensive and I couldn't find any prices or places to buy them .. soooo ..

But thanks again and I'll get in touch with you Andreas when I start building which will be in a week or so !

[Switches with built in LEDs ?]

Hi guys.

Do any of you know where I can get some switches with a built in LED ?

I have been searching the internet for hours but haven't really come up with anything interesting.

Thanks in advance;

[Newbie question (DIN / DOUT)]

Hi guys.

I am a REAL newbie and have a hard time figuring out how to build my MIDIbox.

I am not sure I fully understand what the DIN and DOUT modules are for.

Can anyone tell me please ?

Thanks a lot guys !!
