Joule Thief

prusaprinters

<p>This handy little thing takes a (also almost even dead) AA battery and holds a Joule thief circuit together with a 3mm LED.</p> <p>I soldered the circuit to a 13mm by 14mm piece of perf board which fits nicely to the compartment in the front, hold in place by some hot glue.</p> <p>Positive wire guess through a hole to some crumpled aluminum foil as positive terminal of battery holder.<br/> Negative wire goes all the way back to a slot which takes a M3 nut. I squished the wire again with some aluminum foil down by pressing in the but until a M3 screw can be put through. The screw presses against the battery and holds it in place.</p> <p>The holder itself has some spherical indents on the bottom to reduce warping forces during print =&gt; easy print, w/o brim or supports, no post processing for the print.</p> <p>For more details on the circuit itself, please check on the description or video of Big Clive:<br/> <a href="http://www.bigclive.com/joule.htm">http://www.bigclive.com/joule.htm</a><br/> <figure class="media"> <oembed url="https://youtu.be/K53beWYdIpc"></oembed> </figure> </p> <p>I could never explain it that clear with all theory included...<br/> ... basically I designed this thing to be a housing for this fascinating circuit!!</p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Anet</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>A8</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>0.2</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>15%</p></div><br/> <strong>Filament:</strong><br/> None PLA Blue</p> </p></p></p> Category: DIY
