Nice.. a bit over engineered though, I think if you shout STOP! to flash the headlamp people might not realise what you're doing and people who are are not directing the flash light to may get confused..
You reacted to the "helmet-movie" which I published on YouTube half a year ago. May I inform you that I am going to remove the movie and cancel my "tcwm-identity". I have already published a better version of the helmet movie under my NEW IDENTITY: TonySwitzerland.
I still have a couple of ideas on what to publish next -- so watch out!
Awesome project. I built an analog taillight assembly for a motorcycle but used a few opamps and 555's (of course I couldn't do that cool trick with the mic ;-) ) Anyway, the biggest 'problem' was the very focused light from the LEDs. I solved this by reusing the old diffuser off the motorcycle; but you obviously cant do that.
Also, just curious are you operating the LEDs at the typical operating current (usually around 20mA) or since you are using PWM are you going well above that?
Hey, thanks! On both of my motorcycles I had 555 controlled taillights, too! But now I have modified both with ATTiny13. The LED driver transistors force 20mA trough the LEDs. The PWM can be 100% duty, it would make it quite complicated to control the current duty cycle dependent...!
I am in the process of changing my ID here. Will soon come as TonySwitzerland, which is true.
Well, now I wear a cast around my right leg, after a motocycle accident on August 29.
If you check out a spec sheet like the one at eled(dot)com/data/SPEC/E7114QWC-D.pdf
You can actually run the LED at a much higher current but you have to use PWM to limit the power going through it. They usually burn out due to the element melting; but by using high current pulses it cools off before it can burn up. But in the above you can actually run the LED at 180mA!! but it has to be less than 10% duty and 0.1mS pulse width. Light em up like the sun!! lol ;-)
Look up my "amazing bicycle helmet" video for more information. I tried to erase this one without success.
No, I do not sell it, too much work. Build it yourself!

How much does one cost!?! i want one!

Any fourletter word will do!
To be honest, it reacts to any sound you make.
NEWER VIDEO. I made a new one, search for "amazing bicycle helmet"

that's excellent work. If you market that your sure to do well. Great idea,man.

nice project. Now would I suggest making it wireless? That would be a lot more convenient and cool.

Thank you for your comment. I think that would be possible as long as you do not place the batteries inside the helmet!
INFORMATION TO ALL VIEWERS:
I have deleted this movie some months ago because I made a new one. I deleted my "tcwm" identity and opened the "TonySwitzerland" id.
Strangely enough, this deleted video showing up again. Thanks for you visit, better go to my new id and check the new movies!

Hallo tcwm sehr schönes Project, so ein Helm könnte wirklich jeder gebrauchen . Freue mich über weitere tolle Projecte :D

I just realized that I had logged in with my new ID whe writing the answer. This is to confirm, that I wrote the comment above.
All 555 circuits stopped blinking after 15 secs and switched to steady/bright.
I made experiments with a 100 white LED front beam, but that will come later!

Interesting page, thanks. Will start experimenting with low duty cycles and high current. Thanks for the kick!
