Wireless Power Hub

prusaprinters

<p>I made this Wireless Power Hub to not have to buy the stupid very expensive cell-batteries for the ornament. The original batteris lasted for about 2 days...</p> <p>I wanted to use the ornament as a decoration for our ginger bread house, but I did not want any cables. So I added the "wireless" feature. Now we put the "Hub" under the cotton (snow) and the tree on top and it shines! Then when a kid picks it up, no cables taring through the cotton... And it's like magic that it shines when you put it down! :)</p> <p>Parts:</p> <p>Wireless power transmitter and receiver: <a href="https://www.banggood.com/5Pcs-Wireless-Power-Supply-Coil-Charger-Board-Wireless-Charging-Module-p-1151124.html?cur_warehouse=CN">https://www.banggood.com/5Pcs-Wireless-Power-Supply-Coil-Charger-Board-Wireless-Charging-Module-p-1151124.html?cur_warehouse=CN</a></p> <p>Decoration Christmas Tree (with led inside) was bought on Jysk (I can't find it online, but you can use this Hub for anything using 5v or less): <a href="https://jysk.se">https://jysk.se</a></p> <p>Any power supply 5-12v: <a href="https://www.banggood.com/AC-100-240V-DC-7_5V-1A-1000mA-Power-Supply-Adapter-Charger-p-938450.html?rmmds=search&amp;ID=3426&amp;cur_warehouse=CN">https://www.banggood.com/AC-100-240V-DC-7_5V-1A-1000mA-Power-Supply-Adapter-Charger-p-938450.html?rmmds=search&amp;ID=3426&amp;cur_warehouse=CN</a></p> <p>A barrel jack (female): <a href="https://www.banggood.com/5_5mm-X-2_1mm-DC-Power-Supply-Metal-Jack-Socket-With-Nut-And-Washer-p-934446.html?rmmds=search&amp;cur_warehouse=CN">https://www.banggood.com/5_5mm-X-2_1mm-DC-Power-Supply-Metal-Jack-Socket-With-Nut-And-Washer-p-934446.html?rmmds=search&amp;cur_warehouse=CN</a></p> <p>Bright white Led (I broke the original): <a href="https://www.banggood.com/100pcs-F5-5mm-White-Bright-Diode-Straw-Hat-Super-Light-LED-Assortment-Kit-p-1071913.html?rmmds=myorder&amp;cur_warehouse=CN">https://www.banggood.com/100pcs-F5-5mm-White-Bright-Diode-Straw-Hat-Super-Light-LED-Assortment-Kit-p-1071913.html?rmmds=myorder&amp;cur_warehouse=CN</a></p> <p>And then you need a 20 ohm resistor to lower the voltage to 3.2 volt (for the led).</p> <p>Now, print the two parts, assemble it all and use. :)</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Prusa Mk2</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>0.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div> </p></p></p> Category: Sculptures
