<p>----<strong>Useless Box</strong> ----</p><p>&nbsp;</p><p><strong>Update:</strong> I have quickly added 2 wiring schematics. They are not pretty, but hopefully functional. :-)</p><p>info: Some knowledge of Arduino is required for programming and wiring.</p><p>Another Useless Box, This one is running Arduino with a Li-ion rechargeable battery.</p><p>It is ment to fit the items listed below.</p><p>2 x Tower Pro SG90 9g Micro Servo.</p><p>1 x 5V Step-Up Power Module Lithium Battery Charger.</p><p>1 x D1 Mini NodeMcu.</p><p>1 x Li-ion Battery 18650.</p><p>2 x Switches.</p><p>1 x Led (optional)</p><p>Besides that you will need some screws and wires, soldering iron and a gluegun.</p><p>I you have an old Powerbank, you can use it for the Step-up/charger and Li-ion cell.</p><p>For connections look at the "Useless_Box.ino" or "Useless_Box_Relay.ino" code</p><p>it is pretty simple.</p><p>i tried to make it as small as possible (10.5 x 7.5 x 4.8 cm)</p><p>Optional:</p><p>If you have "Servo twitch" the easiest fix is to run the Servo power through a "relay" See BC547_relay_arduino.jpg</p><p>and use the "Useless_Box_Relay.ino" code.</p><p>If you have any questions, please feel free to ask.</p><p>NB. I did not write the code, I adjusted it to my project.</p><p>It was done by Vagelis Chantzis. <a href="https://www.instructables.com/id/Arduino-Useless-Box/">https://www.instructables.com/id/Arduino-Useless-Box/</a></p><p>See my other Things <a href="/Jubaz/designs/">HERE</a></p><p>&nbsp;</p><figure class="media"><oembed url="https://youtu.be/yktz_bD218U"></oembed></figure><p>&nbsp;</p><h3>Print Settings</h3><p><strong>Printer:</strong></p><p>Creality-CR8</p><p><strong>Rafts:&nbsp;</strong></p><p>No</p><p><strong>Supports:</strong></p><p>Yes</p><p><strong>Resolution:&nbsp;</strong></p><p>0.2-0.24</p><p><strong>Notes:</strong></p><p>Support is only needed on the 2 fingers</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: 3D Printing</p>
