The horns are done!!! We’ll confirm the shipping time in a couple days, but optimistically they should get to our US fulfillment center in less than two weeks. We’ll ship them out to you as soon as they arrive. This means it’s time to gather some information.
Surveys are coming! Most of you haven’t given us your address yet so you will soon receive an email asking for it. You must follow the link and fill out the survey to get your horn.
If you have given us your address (HERO backers) you’ll get a different form to fill out in case you moved.
There is an optional survey too for additional items, these will be sold as extras through our website but you can get them for free now (or later) because we love you so much!
- We provide a Mini USB cable which will let you charge the horn with a computer or any USB wall plug (like those cube shaped apple ones for example). If you need a USB Wall Charger then check the box for that in the optional survey. They won’t ship with your horns but if you need one we hope to get it to you before your first re-charge.
- Some of you (ahoy bent riders!!) need cables longer than the standard 2.5 ft. (76cm). Good news, we’ll have some 2.5 ft. extension cables for you! Fill out the optional survey if you need one of those. If you think you need more than one then send us an email.

More details about production
More pictures have been posted to this album so check it out if you are interested.
We were able to catch several cases of failed individual components, and in each case there were enough spare parts to get the horn working right so we have a full production yield! Also, we’ll be able to send the failed component back to the supplier and get more good ones for the second batch.
Specific problems we found were faulty MOSFET switches which resulted in continuous honking (ouch), battery problems where the battery couldn’t supply the necessary current and a maladjusted tuning screw in one of the car horns.
In some cases (~10%) the green LED to indicate a full charge is slightly blocked on the inside by a stray piece of ‘flash’ plastic. We noticed and started fixing this about halfway through production. Since it isn’t critical (you can still see the light) we thought it best not to delay to adjust the horns that were already built.
We improved on our method for dampening the sound in the factory, first with ziploc bags of water which worked really well, then with an industrial ear protection rig. The tones are a direct proxy for volume so the testing is still effective.
A big thanks
There were only 8 people who built all of the bike horns (one of them took the picture). A first production run is always difficult but together we were able to work out some pretty efficient assembly methods.
Note: silly version of this photo here.
That's all for now, comments welcome as usual and don’t forget the surveys!
