<p>A four legged spider looking skull with LED lights, remote controlled and battery/usb/wall powered</p><p>In the first version, I used a 3v AC to DC converter that I'd taken from one of them LED flame bulbs: <a href="https://smile.amazon.com/gp/product/B07YC8DH7Z">https://smile.amazon.com/gp/product/B07YC8DH7Z</a><br>This is wired to a wall plug which I can then plug directly into a wall socket.</p><p>In the later version, I used an Android Nano and a battery. This allows for adding remote controllability with an added infrared sensor. If you used a Nano 33 IOT, you can use this as a tweet or email alert system with its wifi and Bluetooth capabilities.</p><p>I took inspiration and the legs from this: <a href="https://www.thingiverse.com/thing:1067086">https://www.thingiverse.com/thing:1067086</a><br>Scaled, stretched, and heavily modified them to look more organic.</p><p>here's a video of it all put together. <a href="https://drive.google.com/file/d/17PEO2lHqC6yRx5xcZa-hDS3HyQqYhcPU/view?usp=sharing">https://drive.google.com/file/d/17PEO2lHqC6yRx5xcZa-hDS3HyQqYhcPU/view?usp=sharing</a></p><h3>Print instructions</h3><p>I used a resin printer to print the parts - mind the shrinkage<br>Print two sets of the limbs for four legs - left and right are mirrored.<br>I soldered up the LEDs with 330hz to 1khz resistors.<br>Each set of colors is soldered in parallel and goes to a digital pin.<br>I've included a soldering rig to make it easier to solder the LEDs up.<br>I recommend using thinner wires than I have and to solder them directly to the pin holes.</p><p>Here is a great tutorial on how to wire up the infrared sensor and LEDs, and program the Arduino to work with a remote controller:<br><a href="https://electronicshobbyists.com/arduino-remote-control-communication-arduino-ir-sensor/">Arduino Remote control communication – Arduino IR Sensor Tutorial</a></p><p>Use two M2 screws to screw the top and bottom together</p><p>Here is my Arduino sketch: <a href="https://drive.google.com/file/d/1dUCTPEdhYn-t54r3XKQch3CRxOPCK_mz/view?usp=sharing">sc_01.ino</a><br>It's got a strobe, single color, all colors and flashing modes, and with speed control.</p><p>Requirements:<br>1x <a href="https://www.amazon.com/uxcell-SS-12F16-Position-Miniature-Latching/dp/B01N235HVR/ref=sr_1_10?dchild=1&amp;keywords=micro+switch+on+off&amp;pd_rd_r=6e57a182-ec6a-47cb-a69c-87b46fc12c96&amp;pd_rd_w=vr4u7&amp;pd_rd_wg=3og7M&amp;pf_rd_p=0ec05f25-9534-48fe-9c3e-40b89957230e&amp;pf_rd_r=T6ETHM276RXAQSC7JPF4&amp;qid=1602545985&amp;sr=8-10">Micro on/off switch</a><br>8x standard LED lights<br>4x 330hz to 1khz resistors - depends on your particular LED lights<br>1x 1838B IR sensor<br>Thin wires and solder<br>1x Arduino Nano or an ac/dc converter from an <a href="https://smile.amazon.com/gp/product/B07YC8DH7Z">LED flame bulb</a><br>2x short M2 screws</p>
