# Light Up Prop with Prop-Maker ## Overview https://youtu.be/Tk4QVO6SaqQ ## DIY Electronics & Props In this project we’ll show you how to build a light up prop using Adafruit’s prop-maker! This is fully 3D printed and has a collapsible blade. It’s made from segments that are tapered so it can retract. It makes a pretty cool effect when you swing it around. ![3d_printing_hilt-emitter-angle.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/169/medium640/3d_printing_hilt-emitter-angle.jpg?1560947593) ## DIY Electronics & 3D Printing  All of the electronics are housed inside the 3D printed hilt. It’s also got an accelerometer for motion activated sound effects. It plays different sounds for swings and hits. They’re also randomized and feel pretty responsive to your motion. The blade is removable and the hilt makes a pretty sweet flashlight. Inside the emitter is an insanely bright 3W RGB LED. ![3d_printing_hilt-emitter-up.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/170/medium640/3d_printing_hilt-emitter-up.jpg?1560947749) ## Parts Copy and paste friendly list of products. - [Adafruit Feather M4 Express](https://www.adafruit.com/product/3857) - [Adafruit Prop-Maker FeatherWing](https://www.adafruit.com/product/3988) - [3W RGB LED](https://www.adafruit.com/product/2530) - [2200mAh Lipo Battery](https://www.adafruit.com/product/1781) - [Mini panel mounted toggle switch](https://www.adafruit.com/product/3221) - [Mini oval speaker](https://adafru.it/3923)   ![3d_printing_parts.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/168/medium640/3d_printing_parts.jpg?1560946407) ## Hardware List of screws, standoffs and nuts. - 2x [M3 x 10mm brass standoffs](https://www.amazon.com/gp/product/B06XQ33Y9X/) - 4x [M3 x 8mm pan head machine screws](https://www.albanycountyfasteners.com/Phillips-Pan-Head-Machine-Screw-M3-x-5-p/1066-1008.htm) - 4x [M3 nylon insert locknuts](https://www.albanycountyfasteners.com/Metric-Nylon-Insert-Lock-Nuts-A2-Stainless-Steel-p/5570000.htm)  - 4x [M2.5 nylon machine screws](https://www.adafruit.com/product/3299) - 4x [M2.5 nylon nuts](https://www.adafruit.com/product/3299) - 1x [Focusing Lens](https://www.amazon.com/gp/product/B00YGBKA40/) (5 degree) ![3d_printing_hardware.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/167/medium640/3d_printing_hardware.jpg?1560945348) ## Additional Parts Cables, wires and headers used in this build. - [JST PH 4-pin cable (socket)](https://www.adafruit.com/product/4045) - [JST PH 4-pin cable (male)](https://www.adafruit.com/product/3955) - [Header kit for Feathers](https://www.adafruit.com/product/2886) - [JST PH 2-pin extension cable](https://www.adafruit.com/product/1131) ### Adafruit Feather M4 Express - Featuring ATSAMD51 [Adafruit Feather M4 Express - Featuring ATSAMD51](https://www.adafruit.com/product/3857) It's what you've been waiting for, the Feather M4 Express featuring ATSAMD51.

It's super easy with the **circuitpython.org** website, just click the link below to launch the page. There you can choose to install stable release or beta.  **Quick Start** - Connect board to computer via a known good USB and double press the reset button. - Download the C **ircuitPython UF2** and upload to the **FEATHERBOOT**  drive. - Open **CIRCUITPY** drive and upload the required libraries (listed below) and **code.py** [Install CircuitPython Feather M4 Express](https://circuitpython.org/board/feather_m4_express/) ## Adafruit Circuit Python Libraries Download the CircuitPython library bundle and unzip the folder. Create a new folder in the **CIRCUITPY** drive and name it " **lib**". The following libraries are required to run the code properly. Double check to ensure all of the files and folders are inside the **lib** folder on the **CIRCUITPY** drive. - **adafruit\_bus\_device** (directory) - **adafruit\_lis3dh.mpy** - **neopixel.mpy** - **adafruit\_rgbled.py** [Download Library Bundle for CircuitPython](https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases/latest) ## Upload code.py Click the link below to download the project  zip – This contains the code, audio and 3D files. Upload the **code.py file** to the **CIRCUITPY** drive. Create a new folder on the **CIRCUITPY** drive and name it " **sounds**". Upload the audio files to that folder. The code will run properly when all of the files have been uploaded. https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/PropMaker_Light_Up_Prop/code.py ## Settings and Customization If your are building the project as is, you shouldn't have to edit any of the values in the code. But, if you have a different setup, you'll want to read through the comments and make your desired changes. - Use the `MAIN_COLOR` and `ALT_COLOR` variables to change the main color of the RGB LED. - Accelerometer sensitivity can be adjusted in the `HIT_THRESHOLD` and `SWING_THRESHOLD`. - Audio is set to output via pin **A0** (That's the analog pin #0 on the Feather M4 express). ## Audio Files The sounds used in this project are from the JKDF Soundfont pack, available to [download here](https://www.fx-sabers.com/forum/index.php?topic=41379.0). The pack contains various sounds that are already in the supported audio format. Select the files you like and name them accordingly.  Adafruit CircuitPython supports **16-bit, Mono, 22.050kHz .wav** audio format. [See this guide](https://learn.adafruit.com/microcontroller-compatible-audio-file-conversion) to help format any audio files you might want to use in this project besides the files provided. In the main loop, the swing and hit modes randomly choose from a list of sounds. For example, swing1.wav, swing2.wav, swing3, etc. This makes the motion effects feel much more varied and sounds less repetitive. - Power on – **on.wav** - Idle looping noise – **idle.wav** - Swing whoosh – **swing.wav** - Crash strike – **hit.wav** # Light Up Prop with Prop-Maker ## Wiring https://www.youtube.com/watch?v=Z6CD1QnK2to Info: **The voiceover transcript is available below.** We’ll start by assembling the headers on the Adafruit Feather and Prop-Maker Insert the strip of male headers into the row of pins on the outer edge of the PCB. I like to use a breadboard to help keep the headers straight. Just be sure to line up them up properly. With the headers now place we can solder all of the pins. If you’re new to this, be sure to check out Adafruit’s guide to excellent soldering. Once all of the pins have been soldered, you can remove the PCB and double check to make sure they have enough solder. Next we can install the female header on top of the Feather Express. To help with installing the headers, we’ll use the FeatherWing– Just snap it top and this will help keep the female headers in place while we solder. I like to use a PCB vise – This helps keep it in place so it doesn’t move around. The stick vise is nice because it lets you clamp it down. With the PCB secured we can add solder to install the female headers. When soldering, you want to heat up both the pad and the lead and then add solder. Once applied, remove the solder but keep the iron still on the joint a bit and then remove the iron. Once we’re done soldering, remove the PCB and inspect the joints – you’ll want to make sure there’s enough solder and no cold joints. We’ll use a 4-pin JST cable to connect the LED to the PropMaker. Since it’s an RGB leds it’ll need four wired connections. Third helping hands keep the PCB in place while we solder up the wires. For more grip we put pieces of heat shrink tubing on the little grabbers. Once it’s in a good spot we can tin the pads by adding a bit of solder. You’ll need to be quick about it because the aluminum backing dissipates heat making it a bit tricky. Next we can plan out the wired connections before soldering to the pads. Here I’m connecting the white wire to the blue pad. Green wire to the green pad. Red wire to the red pad. Then connecting the black wire to the common anode. Be sure to check the joints. These need to be pretty solid. I did this a couple of times before getting good connections. We’ll use a 2-pin JST cable to connect the toggle switch to the PropMaker. Use wire cutters and shorten the cable. We’ll need these two cables for their JST connectors. We’ll solder one of these JST cables to the toggle switch. Using wire strippers, remove a bit of insulation from the wires. Tin the exposed wire by adding a bit of solder. This will prevent the strands of wires from fraying. Now we can connect the cable to the leads on the toggle switch. Helping hands will keep the switch sturdy while soldering the wires. Add a bit of solder to the leads first then we can get the wire connected. Make sure to connect the middle lead and then one of the other leads on either side. Double check your wiring and make sure the connections are solid. Next we’ll connect the other JST cable to the Propmaker FeatherWing. I’ll start by securing the PCB to the stickvise with the bottom side facing up. Add a bit of solder to tin the enable and ground pins. Now we can connect the two wires from the cable. Polarity doesn’t matter as long as both pins are wired. With it connected to the enable and ground pins, the toggle switch can cut the power. This JST cable is positioned to go in between the Feather and FeatherWing. Next we’ll connect a 4-pin JST cable to the PropMaker. This will connect to the 3W RGB LED. The connectors snap together and make the assembly much easier. I’ll fit the PCB back onto the stickvise bottom side up. Then tin the RGB LED pads on the Propmaker. We’ll need to match the connections with the wiring on the 3W RGB LED. Double check the wired connections and make sure the joints are solid. Now we can snap the PropMaker on top of the Feather. Go ahead and plug in the LED and toggle switch to the Propmaker using the JST cables. This mini oval speaker connects directly to the speaker port. We can also plug in the lipo battery to the Feather. Once the code is uploaded, we can test out the circuit and make sure everything works. # Light Up Prop with Prop-Maker ## Assembly https://www.youtube.com/watch?v=UMlplbbbQBk Info: **The voiceover transcript is available below.** We’ll start the assembly by building the emitter. Join the emitter cap to the LED plate and line up the mount holes. Then insert the brass standoffs into these holes. Now we can insert two screws into the remaining holes. Tightly fasten lock nuts onto the thread of the screws to secure the parts. Next we’ll set the RGB LED and battery. Insert the JST cable from the LED and put it through the hole in the middle of the emitter. Grab the battery holder and pass it through the JST cable. Place the wires on one of the groves. Then, fit the battery through the holder. Make sure the cable is facing outside. Now we can begin to fit the battery through the top of the hilt. With the cable going in first, insert the battery holder and fit it through the hilt. You can then start to screw the emitter cap onto the hilt. Be sure to pull the battery cable out the other end. Next we can install the mini toggle switch. Grab the cables to make room and insert the switch into the opening on the hilt. Fit the actuator through the mounting hole so it sticks out the other side. Now we can add the washer and hex nut over the stem of the switch. Grab the LED and position it so the mounting holes line up with the brass standoffs. Begin to insert and fasten machine screws to secure the PCB. Use a screwdriver to tightly fasten the screws. Next we’ll setup the feather and propmaker with the PCB holders. This will make it easier to fit the PCBs through the hilt. These fit over the mounting holes and clip onto the edges. You’ll need to install these on both ends of the PCB. Double check and make sure the tabs are lined up with the mounting holes. You can go ahead and secure them in place using M2.5 nylon screws. The groves on the sides will allow this slide through the rails inside the hilt. Next we’ll install the speaker. Start by threading the cable through the opening on the side of the hilt. Pull the cable through the bottom and keep the speaker outside the hilt. Now we can start to install the PCB holders through the hilt. Line up the groves with the rails and push the PCBs through the bottom. Insert it about half way through and get ready to plug in the speaker and battery. Grab the speaker cable and plug it into the speaker port. After that we gather up the remaining JST cable and plug them up. Here we’re making the connections for the LED and switch. With those now plugged in, we can go ahead and connect the battery to the feather. The PCBs can now be pushed up inside the body of the hilt. And we should still have access to the microUSB port. You can then grab the pommel and screw it onto the bottom of the hilt. One of the last parts to install is the speaker Start by peeling off the protective backing and then go ahead and stick it into the speaker holder. You’ll need to press fit it into the holder. Now we can install the speaker holder onto the hilt. Groves on the inside of the holder wrap around the rail along the outside of hilt. You can pull apart the clip to fit it over the hilt. Next we can set up the lens holder and blade. Place the focusing lens over the center of the holder. Then grab the lens cover and line up the parts so they press fit. The lens cover twist locks into place. The shield covering is then installed to the outside of the lens holder. With the lens holder now assembled, we can screw it on top of the emitter. These parts have threads so they’ll need to be tightly fastened. With the emitter now put together, you can install the blade. This can be press fitted over the lens holder. The tolerances are snug but it’s still removable. For a more permanent hold, you can use super glue or other adhesives. Go ahead and turn it on – Check out the light diffusion in the blade. Different types of filaments will affect the light diffusion. The focusing lens contains the light and helps prevent light leaking. ![](https://cdn-learn.adafruit.com/assets/assets/000/077/176/medium800/3d_printing_cosplayprops-adafruit.jpg?1560956574) Danger: ## More Project Ideas Check out the following tutorials for more ideas and inspiraiton.
