<p><strong># Bike Charger</strong></p><p><br>The idea here is to have a simple bike charger that will use a bicycle dynamo to charger a standard USB powered device (phone, power bank, etc). It works by converting the AC from the dynamo into 5V DC using a standard rectifier circuit. This is intended to work with Android devices (tested) - it will not work with Apple devices - for those to work there needs to be a specific voltage (between 0 and 5V) applied to the middle two pins of the USB plug.</p><p><br>&nbsp;</p><p>Before using on your favourite device <i>*please*</i> first test on your least favourite device.</p><p><br>&nbsp;</p><p><strong>**DISCLAIMER**</strong> - I do NOT take any responsibility for any damage to you or your device.</p><p><br>&nbsp;</p><p><strong>## Bill of Materials</strong></p><p><br>&nbsp;</p><p><strong>### Printed parts</strong></p><p><br>&nbsp;</p><p>1.
