DIY Wooden Stick Lights




Introduction: DIY Wooden Stick Lights

About: Hi, I love making cool and innovative stuff. I'm really interested in electronics, wood working and 3D printing. Studying Indistrial Design Engineering

Hello, it has been a long time since I read instructables and this is my first one. I assume that I will not enter in every details but if you need some, that would be a pleasure to add them :-)

At the beginning of the year (2016) I started this project and here is what I've done :

palo is a light stick which has magnets on the bottom to fix it on the desk, in the kitchen or elswhere. Tap on it and it lights on, tap again and it switches off. It is portable with a long battery life due to the great warm white LEDs and it charges wirelessly.

Required parts :

None electronic stuff :

  • 4 mm pin wood / other

  • 4 mm or less plexiglas with sandpaper

  • 8 neodymium magnets D5 x 3 mm

  • 3 screws and 3 nuts M3 if you don't want to glue the back like me

  • Electrical tape for insulation

  • Shrink tube

  • Epoxy and wood glue

Electronic stuff :

Step 1: Design

During my internship I was able to use a laser cutter so it was a great opportunity for me to create a wood project without spending too much time on the frame. I wanted something great looking, usefull/practical and human friendly.

The frame is a 7 layers of 4 mm pin plywood (you can use whatever you want but this one gave a nice finish on the side with the laser cutter). You will find the DXF file bellow for laser cutting and CNC router. It has a large 3Ah lipo battery so you can use it several hours without charging it. When not using it, place it on a Wireless qi charging dock and it will charge. To switch it on or off, tap on the piezo sensor which is bellow the first plywood layer

Step 2: Assembly

As the assembly is a combination of solder and glue parts, I preferred to make some diagram that explain the whole thing.

It isn't complicated to assembly. If you're not sure how to do it, solder first, do some tests and then glue. You can arrange the electronics as you want. I tought my way is good but you could probably do better ;-)

NOTE : disassemble carefully the QI module to extract the coil and the flexible PCB. Remember the wiring.

Step 3: Upload the Code

Plug the arduino nano to your computer and upload the sketch bellow. I didn't do it yet but you could add a sleep mode the would reduce the consumption of palo when not using it.

Step 4: We Are Done!

I hope you appreciated this project. Here are some pictures that illustrate the final result and my practical uses :-)

See you next time!

PS : if you have any questions, it will be a pleasure for me to answer

    Hi john! Thanks for the nice comment! I thought that the illustration would make more sense that multiples steps :-)

    Simple & Elegant Design. I really like your cartoonish illustrations & the blueprints in your Instructable.

    Thanks! Actually I wished that the plywood would bend slightly when touching it but it doesn't. At least it gives a nice look and indicates the power button (which is very important BTW)

    Try some of these kerf patterns by Aaron Porterfield. They look great and they're super flexible.

    Where did the Qi sheild come from? It wasn't super clear whether it was part of the Qi module and you disassembled it or bought one. Is that PCB/driver packaged along with the coil?

    I used a wireless charger for smartphone (see the picture above with "wireless charger" written on it). The charger contains the coil and the PCB ;-)

    Thanks! I had no choice to have multiple layers but it gave me the opportunity to build a structure inside of it ;-) Sometimes it's good to have producing problem in order to find new solutions (I wanted to use the laser engraver for example)

    Elegant design! I like the integration of wireless charging and the piezo as a switch.

    Thanks! I am wondering if there is a better way to create a touch sensor, let me know your ideas!

    I forgot to add them! They are 5050 warm white LED strip 5V none water-proof. I added a link in the required parts, thanks! They are bright but more powerful ones could be better.

    Thanks, I was just wondering because their spectrum looks really nice.

    Totally awesome! Looks beautiful and very useful.

    Beautiful!This is a fantastic way to integrate the switch into the case, I've never seen a piezo used like this before.

    excellent. love it.

    What an excellent first instructable! I love the look of your light! So great!
