TomoHawk Posted January 14, 2015 Author Share #25 Posted January 14, 2015 The Accel has EFI and micro-controllers like any modern car, so I'll presume that it is what makes the ding-dong go. It just gives it a shot of +12V, then turns it off, like it would for any warning lamp. I"ll be there is a way to do this just as simply without the bulb, but it eludes me until I find it. I'll go look in my Enyclopedia of Electronic Circuits Vol 1, Graf, Rudolf.

TomoHawk Posted January 14, 2015 Author Share #26 Posted January 14, 2015 My next idea would be an LM3909 with a relay in stead of the LED.

TomoHawk Posted January 16, 2015 Author Share #27 Posted January 16, 2015 Now that we have a working way to make the dinger work, I checked to see if there are any other cars that can be a source of this chime unit. The results are that the earlier models built around 2000 had them: 2000-2005 accent2000 Sonata2000 Tiburon2001-2002 Elantra the models built starting about 2009 had an electronic bell-sound of chime. Also, the dinger like I have would be located above the gas pedal.

TomoHawk Posted January 26, 2015 Author Share #28 Posted January 26, 2015 I found this simple little circuit. It's supposed to flash an LED once every 5 seconds, but I'm sure you can change the timing to something better for a ding-dong.

Captain Obvious Posted January 27, 2015 Share #29 Posted January 27, 2015 Haha, well yeah... It's a 555! I thought you were looking for super simple simple. If you were willing to put something together using a 555, we could have come up with a solution a page ago.

TomoHawk Posted January 27, 2015 Author Share #30 Posted January 27, 2015 That 555 circuit only has 5 parts to it, and the ones in my cookbook have a lot more, plus a bunch of transistors, so I will use the blinky light for as long as it will last, and I'll use these long, dark days to etch a few copies of the circuit board. I'd hate to waste the etchant on just one tiny PCB. The 555 circuit still needs a bit to drive the dinger anyway.

TomoHawk Posted March 16, 2015 Author Share #31 Posted March 16, 2015 Having tested the Tridon EP-34A flasher unit, I think it would be fine to control this dinger. You might think that $13 is a little too much to pay for a thing to make your car go ding-dong, but when you consider that you're saving your $100 battery, it might be worth it, especially if you can get one very cheaply from the JY.

Captain Obvious Posted March 17, 2015 Share #32 Posted March 17, 2015 Cool. I'm assuming this is one of those electronic flashers we were talking about near the top of the thread? Did your flashy bulb burn out already, or are you just planning ahead?

TomoHawk Posted March 17, 2015 Author Share #33 Posted March 17, 2015 I won't even get to install it for a month or two, o I'm considering improvements or alternatives. Would you prefer sort-of-random ding-dong of the bliky lamp, or the precise one of the LED flasher?
