<p>I found this model some time ago and kept it in mind as an idea. 1 week ago I received from a broken garden solar lamp a 1 Watt panel (80mm x 120mm x 3mm). I used the model from dkennell as a template and adapted to my parts.</p> <p>Can be powered by sun or 5V USB or 5V DC.</p> <p>Output 5V and 500mA.</p> <p>Used parts:</p> <ul> <li>Adafruit USB DC Solar Lithium Ion Polymer charger V2</li> <li>Lithium-Ion Polymer Batterie 3,7V 2500mAh</li> <li>USB DC-DC 0,9--5V to 5V Step-Up Power Supply Converter</li> <li>3 white LED´s (15000mcd)</li> <li>1x 10ohm resistor for the led´s</li> <li>one small and one big switch</li> <li>optional Toslink cable for the indicator led´s</li> <li>4x M3x 15mm screws</li> <li>MANY hotglue ^^</li> </ul> <p>AND some sun</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>i3 Prusa</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>Yes</p></div> <p><strong>Supports:</strong></p> <p>Yes</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2</p></div> <p><strong>Infill:</strong></p> <p>20%</p> <h3>Post-Printing</h3> <p>A few openings had to be filed. Thread was cut into the 4 holes of the bottom part. Bolt together with 4 screws M3x 15mm</p> <p>I fix the components with hotglue and I used an old Toslink cable (fibre optic) to extend the original status LED´s to the "edges".</p> <p>The small switch next to the large switch for the LED's is for the current output, since otherwise there is a permanent current and the status LED lights up.</p> </p></p> Category: Electronics
