A cure/replacement for the self canceling signals

[sschering]

Just wondering.. Why use a relay instead of a MOSFET like this that costs $1? http://www.sparkfun.com/products/10213
Headlght OK maybe a relay but everything else is only on for a short duration.

As for long lights I would think you could code the shut off timer to watch the speedo signal.. If the speedo stops sending halt the count and resume when the bike is moving again.

If making the PCB is an issue look at DorkbotPDX

http://dorkbotpdx.org/wiki/pcb_order

They do group PCB orders for $5 a square inch for 3 copies of the board.
If your board takes up 2 square inches you get 3 of them for $10 shipped..
That is etched, solder masked and silk screened..

They will work from Eagle cad file so you don't have to mess around with Gerber files.

In my case I thought it to be better to use relays just for ease of servicing on the road, but for a buck a piece I just may go ahead and plan to use them.

And thanks for the link to Dorkbot, I'll need to find a cheep method of making up the pcb's as well. I had these folks bookmarked http://www.expresspcb.com/ExpressPCBHtm/Download.htm but hadn't started looking at other venders yet.

I think it would be best to reset the timer when it drops below a set speed threshold then returns back above it.

ok, 2 relays and remove a spring, sounds like a plan, now to figure out why i have no blinkers at all, course, that tscu may be why

[rustybronco]

These tscu's are known to go bad. I have 6 or 7 duds in my parts stash.

Does the turn signal switch on your bike have a spring loaded lever that you push down to cancel? A lever like this switch has?

[rodman101]

yes it has left right and down to cancel
so far all i know is that i have voltage accross the turn signal fuse, havent tested any further than that, oh, and good bulbs

BatchPCB is another option

http://batchpcb.com/index.php/Products

They have a $10 setup fee and $2.50 pr Sq inch
Shipping is extra with them but you can do a singe board order vs 3 with Dorkbot.

For a one off prototype I've had success with toner transfer from laser printed images on Dollar store photo paper onto copper clad from Radio shack.. 4x6 copper board at Radio shack is about $4.. the rest of the supplies is $5-$6

Print the circuit right from Eagle cad.. use big fat traces for easier transfer.
Layout tip. It's easier to etch a fine gap between traces then a fine trace with wide spacing. Toner transfer isn't perfect so go big
Iron the image onto the PCB with a clothes iron.. take your time.. press down, lift, move.. take you time and don't wiggle the iron or the image will smudge..
Give it 3-5 min total with the iron on high..

When done drop the board with the paper stuck to it into a dish of hot soapy water and let it soak.. The wet paper will fall apart easily leaving the top layer and toner stuck to the board.. just rub the paper off with your finger.. Any small breaks in the toner (or big) can be patched up with nail polish.

I etched the board using Vinegar and Hydrogen peroxide (mix 1:1 ) and a little bit of salt.. Don't go nuts with the salt.. They use calcium carbonate as an anti caking agent so adding a ton of salt just helps neutralize the vinegar. It took 12 hours to etch a 1oz clad board but it does work.

Failed toner transfer and post etching cleanup can be done with acetone.

Mr Barr, Instead of using two picaxe's, what about these?

http://www.ti.com/tool/msp-exp430g2 at whopping $4.30!

http://www.ti.com/tool/ez430-f2013 $20.00

If I spoke 'C', I might already be spending money on this...

[rodman101]

ok, call me stupid, but what exactly does this object do, not labeled, and its not connected, wires are taped off. dont know if this is the tscu or what, found that i do have voltage to the turn signal switch. and the turn signal switch contacts are working fine. oh, the object im refering to is the one between the flasher relay and the main fuse
im a glutton for punishment, but this thing is gettin rediculous, lol

[rustybronco]

Stupid.....

[rustybronco]

That was what you wanted someone to do correct? (couldn't resist it!)


The item you are referring to looks like a voltage regulator, but it's hard to tell from your picture. Can you remove it and take a better picture of it?

***edit***
Your tscu is on the other side of the bike and looks like this ->

[rodman101]

ok, didnt have time to pull it off, but the piece directly to the right of the nipendsho flasher relay, probably didnt spell that right, oh and the bike is a 79 gs1000LN, there is nothing writen on it, label at top is worn off, has 3 wires, a yellow, a light blue with stripe and a ground it seems, part is not hooked up soooo?

[rustybronco]

The colours on the regulator should be yellow and white with a blue tracer. That looks like the regulator, but if the wires are disconnected it can't regulate and it would have to had something else wired up in its place.

Is the unit with the ground wire attached to the center of it disconnected as well?

[rodman101]

no, it is hooked up, bike functions fine, except for the blinkers though, like i said, i found the blinker switch has voltage to it and the switch functions properly, if this part is not in use, i may remove it
and u are correct about the colors, yellow and white with a blue trace

[rustybronco]

What is your charging system voltage at 4~5000 rpm?

[rodman101]

not sure, bike not running at the moment, i pulled the tank as it has a liner in it that is peeling, gotta get that fixed or replaced before i gum up my carbs, lol
