DIY Turn Signal Sounder (Reminder)

[BusyWeb]

Hello, there.
This is just for the fun/hobby project.
I got made a final working device for it.
WARNING!
If you want to do yours, as this circuit is not professionally proved one,
I don't have any responsible for any damage on your bike and/or other means of properties.
:whistle:
Here are my drawings.
Anyone who has better tips about this project,
please let me (us) know so that I can implement it.

Looks great. I think I have most of the parts for this.

Busy, looking at your circuit it seems like you forgot the little capacitor between the 555's leg 2 and ground that generates the tone, it gets charged via the two resistors above it and discharged via the one resistor above it and leg 7.

In your drawing, there is a connection between 2 and ground....

Please check '555 beeper circuits' on the web and you'll see.

Thanks Mr. 5th_bike!
I might missed when I copy and draw.:oops:
I uploded fixed version of drawings, deleted wrong drawings.... :blush:
I hope this version is OK.
But actual my circuit/device is little bit different from my drawing.
There is additinonal components which checks light strength and triggers beep sounds.
Initially, I intended my device put over turn signal blinker bulb with own bettery and own LED light.
But I found that it is hard to put over blinker because of device size, and changed plan to use bike's bettery power.
Studied service manual, which I downloded from here Thaks for that, and found rear signal lines are good place for this project.
Device can be placed under the seat.....

With some study, I got confidence about GZ electronics little.
And I installed cigarette power outlet from bettery by myself, so I can use my GPS power adapter.
I used positive line for tapping out from rear brake line, so line should go on/off with bike engine/key.
Saving some battery cost. :roll:
Let me draw this one and will post it, someone might needed.

I want to do some more projects with power outlet when I have idea and spare time, might be in this winter time.

To Mr. Badbob....
Sorry for the wrong circuit.
If you have planed for it, please research more about 555 timer sound circuit from internet.
I did researched alot to find appropriate circuit....and learned from it. :blush:
There might be better one out there.

Thanks again for the comments.

I got lots of experience with electronics and have built lots of circuits with 555 times. I have a book on them around here somewhere.

That releases my worry over mistake.:roll:

Today, I found some good tool for the electronic design from Make web site.
If you interested in, please check this web site. (free, and alpha version)

I downloaded minutes ago, and currently re-drawing my schematic with this tool.
After finished, let me post it.
Easy to use and I like it very much.

Here is the Breadboard TEST Circuit Drawing.
Drawing tool can be downloaded from (free):

I think that this tool is good for the small circuit. :cool:
