Phone Heads Up Display, camera and light mount.

<p>This is a phone mount for bicycles, designed to incorporate all the functions I wanted in this sort of mount.</p> <ol> <li>A slot that friction fits an Alcatel U5 (you'll need to modify it for your phone's dimensions)</li> <li>A hole for a Micro-USB cable to charge the phone on the road.</li> <li>Fitting points and a mount for a RunCam HD</li> <li>Fitting points for an LED headlamp.</li> <li>Provision for wiring.</li> <li>A space for taking a credit card and keys.</li> <li>Clamping space for 25.4mm diameter handlebars (adjust for your own bike)</li> <li>Rafts for printing successfully in ABS.*</li> </ol> <ul> <li>Printing in ABS is strongly recommended. Early designs were produced in PLA and cracked regularly. ABS with 8+ perimeters and an Acetone bath make it nearly indestructible.</li> </ul> <p>The photos of the red mount are of an early prototype with a ZTE Blade.</p> <p>I recommend IP Bike for Android as a bike computer for a mobile phone, but that's really up to personal preference.</p> <h3>Powering your devices</h3> <p>Most devices that you'll plug into a mount like this will only require 5v power. Action cameras, phones, and some LED powered lights can all be powered directly from a regular consumer USB battery pack. Alternatively, if you want to build the electronics yourself, the following items can help you wire it up:</p> <p>A <a href="https://www.aliexpress.com/item/4000016788472.html">5v Boost converter</a> can help deliver reliable 5v power, while a battery like an 18650 cell discharges.</p> <p>Note that you can recover 18650 cells from E-waste free of charge.</p> <p>Additionally, a <a href="https://www.aliexpress.com/item/4000522397541.html">TP4056 protection circuit</a> will allow you to charge your battery safely via USB.</p> <p>Both of these components cost very little, and can be connected to a large parallel battery for long rides, though this would charge slowly with the TP4056 module.</p> <h3>Future plans</h3> <p>As it stands, the mount is suitable for most riding that I do. In the case of inclement weather I can easily just put a clear plastic bag over the mount and fix that with elastic bands to the stem. I will probably include a waterproof casing for a <a href="https://www.aliexpress.com/item/32917656425.html">voltage readout</a> on the rear of the mount relatively soon as mine is just hanging there loosely.</p> <p>I also want to modify the front of the mount to have an easy to remove clip type assembly for the components like the light, camera and battery. This would make getting ready to go for a ride, and removing the battery for charging a bit easier, but at the moment it's not too much of a bother to just plug things in before heading out. Autostart when charging for the camera would be nice too.</p> <p>I'm also considering adding a PAM8403 amplifier board, and two recovered sets of speakers from a laptop to the ends of my handlebars for higher quality audio while riding. You can either get a PAM8403 with bluetooth to pair it with your phone, or you can use a regular audio cable.</p> Category: Sport & Outdoors
