Have you ever gotten in an accident while riding a bike at night or close to an accident? Gotten honked at because of irresponsible drivers who aren't paying attention to the road? Or simply just want to make bike riding more safe? Riding visibility on a bike is at all time lows during night time considering of little space we take up and as well as us not being able to have car headlights blinding everything and everyone. If you agree with at least one the above statements, then the Automatic Activated Blink Signal is just for you!! Check out the awesome EL panel, lighting up like lightning! Drivers will be sure to notice you riding, and not crash you! It will ensure 100% safety when you're riding your bike through dark streets at night as well as having hands free operations.

This project will automatically turn on an EL panel with a mercury tilt switch. By extending your arm or raising it slightly, the mercury will complete the circuit, resulting in the EL panel to light up brightly whether solid or blinking. Give this project a try, and you'll be amazed.

Step 1: Materials

First, you'll need to gather the necessary materials for this awe-inspiring project:

1. EL Panel w/ AA-powered AC Inverter  [2] *these may be separate or if you'd like to have solid EL panels, soldering might be required)
2. Mercury Tilt Switch [2]
3. Velcro strips [4-6 pairs]
4. 1.5V Button Cell--LR44 / AG13 [2]
5. Electrical Tape
6. Armband [2]

<p>i am trying to order the AC Inverter. which one out of the two options given was used? the 5VDC AA inverter or the 3VDC AA Inverter?</p><p>thanks!</p>

Good idea except that all hand signals (left turn, right turn and stop) are done by the left hand.
From bikeed.org: The right turn signal has historically been the left arm outstretched and bent upward at the elbow. This action completed by a motorist sitting upright in a car is clearly visible. For a bicyclist in riding position, this signal may be difficult for motorists to see. Some states now allow the right outstretched arm to indicate a right turn. Always use hand signals when turning, changing lanes and even when changing position in a given lane. Motorists will appreciate the courtesy and respond in kind.
Although your comment is true, there are lots of people in this world who does not know or forgot the hand signals. This way, there would not require any memorization of what direction your arm needs to be.
It also depends on local laws. Where I live (BC, Canada, where we drive on the right) it is legal for cyclists to signal right hand turns with the right hand. However I still use my left hand.
We all expect people who drive cars to know the rules of the road, and obey them.<br>We cyclists should too.
Not in the UK!!! <br> <br>
Awesome! You should enter this into the <a href="https://www.instructables.com/id/Scoochmaroo-Challenge-Fathers-Day/">Father's Day Challenge</a> that is ending at midnight tonight!
You could add a transistor oscillator to make it more cool! But anyway, great project!
I like the idea and I support what it stands for (I'm a bicycle commuter in an unfortunate location) but I do wonder whether it's good practice to break from traditional hand signals? Of course, I'm starting to encounter drivers that don't know the hand signals (it would seem) and that's a bigger problem. I hope this rig works well for you.
great idea...really diggin' that rat-tail too!
Thanks! Haha i'm sure Michael appreciates all the love his tail is getting :D
Gtreat minds think alike I guess Unfortunately<a href="https://www.instructables.com/id/Automatic-Bicycle-Hand-signal-triggered-Indicator-/" rel="nofollow"> I did mine </a>three weeks too soon for the bicycle competition. Good luck with yours!
Our inspiration was from you! The materials that you listed were quite expensive and really hard to acquire with a tight budget considering that we are high school students. <br>So we modified to it to fit our budget and our fancy. With cheap and easy to acquire resources, as well as dangerous ones (mercury), we were able to recreate one with similar attributes but without the need for cash and a more flexible and user friendly interface. We're still tweaking it, and getting feedback from comments. <br>But all in all, thank you for your inspiration!
Yeah, I had kind of guessed that. There's nothing wrong on Instructables with taking someone else's instructable and incrementally improving on it, in fact it's actually encouraged, but you're expected to acknowlege that you've done so by mentioning it in the 'ible. But it's OK, you're new here and you'll know the next time. <br> <br>By the way I've made two improvements since I posted mine - the first is to skip the button cell and use the standard AA - but with a 'battery interrupter' in series - look for examples here on instructables. Battery Interrupters were designed as a way of controlling battery powered devices for the disabled, so making one with a tillt switch would actually be a dual-use technology, letting disabled people find other uses for the tilt switch part. And the second is that I found a cheap wrist strap wallet at a sports store, which not only lets you move the indicator closer to your wrist for better visibility, but it also gives you a nice insulated zippered pouch to store the battery and transformer, if you want to get the bulk down by doing away with the plastic case. <br> <br>regards, <br> <br>Graham <br>
Yeah sorry for not mentioning it, but thanks for understanding! <br>Wow, that sounds like a quite an improvement! I never heard of an interrupter so i'll most likely look into that! <br>I really like that strap on wallet idea! But that's all you, so you should add that on. It's a really good improvement, maybe put something reflective on it as well? Visibility is always a good thing to have more of!
Absolutely genius. This is an amazing project. :D
Excellent project! What is the source of the EL panels you used?

Well done. Very well done.
Thanks Bording!
Wow! This is grate for when I go bikeing. It is absolutely geenius.
