Hello everyone !

For Christmas I made 2 small wooden washing machines to offer 2 children, one for our daughter Colyne and one for her friend Noah. The "Magic Wash" are made of wood (MDF) and really work (without water of course).

It is powered by a 12V battery and is controlled by an Arduino Nano.

The video:

Characteristics :

  • Scale: 1/2
  • Dimensions: width 30 cms, height 40 cms
  • Weight: 6 kg
  • Digital display of remaining time and other info
  • Drum rotation in 10-second increments (max. 60 seconds)
  • Progressive acceleration and reversal of direction of rotation every 10 seconds
  • Immediate stop of the motor when opening the door (display PO)
  • Displaying the child's first name at startup
  • Automatic standby after 5 minutes
  • End of Wash Beeps
  • Rechargeable battery powered 12V
  • Controlled by microcontroller (Arduino Nano)

Purchasing:

TOTAL: 43,01 €

  • Jigsaw
  • Drill
  • Screwdriver
  • Compact crosscut saw
  • Router
  • Glue gun
  • Hand tools (hammer, files, saw, screwdriver, cutter, pliers, chisels ...)

Production time: approx. 30H

Step 1: The Drum

The drum is made from a recovered can of product.

It is cut with a cutting disc and covered with vinyl sticker imitation chrome.

The edges are protected with electric cable sheath.

And to be sure to fix the bearing in the center, I printed a drilling template.

Step 2: The Door With Porthole

The door is cut with a router in 3 steps:

  1. First circle to embed the porthole
  2. Second circle for external cutting
  3. Third circle for internal cutting

The contours are then rounded with a suitable cutter

For glass, I used a serving bowl purchased from Ikea :
VARDAGEN, $2.99, Article Number: 602.892.3

Step 3: ​The Carcass

The carcass of the machine is made of 6 mm MDF.

The front face is cut and the elements are assembled together with glued and screwed rods.

The machine then receives 2 coats of white paint.

Step 4: Opening Sensor

To detect the opening of the door I glued an alarm sensor (reed switch) behind the facade, and a magnet on the door.

Step 5: Assembly

The feet are made with 4 water bottle caps.

The hublot is glued with windshield glue.

A simple hinge allows the door to open.

And I recovered the red window of the display in an old alarm clock.

Step 6: Motor

For the rotation I used a geared motor of 12V and 300 rpm with a roller of rubber recovered in a old printer.

I created a height adjustable bracket to adjust the pressure on the drum.

Step 7: Electronic

For the display part I followed this article of madebyjoe: https://www.instructables.com/id/Arduino-powered-7-...

To control the engine I used an all-purpose H-bridge: a L298n.

Then there are very few components because everything is ensured by an Arduino Nano (the code is available for download).

Note: I removed the power LED from the Arduino and the L298 to conserve battery power.

Step 8: Circuit Board

For the printed circuit board it is classic:

  1. Creating a transparent typon
  2. UV insulation
  3. Pass into a developer ban
  4. Engraving in iron perchloride
  5. Drilling
  6. Welding of composters.

    For power I used a rechargeable battery of 12V and 1800 mAh with switch.

    Step 9: Drum Mounting

    The drum is attached by a turntable bearing.

    By putting cloth in the drum, I realized that it was sliding instead of being trained. So I added 3 wooden triangles covered with chrome to train the clothes. Looks like Toblerone! lol

    Step 10: Inside Overview

    And finally, a lid comes to close the back.

    Step 11: Done!

    This is how to please 2 children for Christmas!

    Strangely it is more fun to "wash" toys rather than clothes (Playmobil, car, ball...) lol

    <p>I'm so happy to have won a prize in &quot;<a href="https://www.instructables.com/contest/woodentoys/winners/">Wooden toys</a>&quot; challenge with my washing machine !</p><p>Thanks everybody and thanks to Instructables :)</p>
    <p>Wow. </p><p>This is awesome. </p>
    <p>Amazing! What a toy! I thought of making a toy electric cook top, but never did. Your work inspires me! </p><p>Congratulations on being a finalist in the Wooden Toys Challenge!</p>
    Thank you ! Yes I do not think I have ever seen a motorized wooden washing machine for children. I inovated lol<br>Congratulations to you too for the snake!
    <p>Very neat work and nicely executed project!! You just got my vote :)</p>
    <p>Thank you for your vote ;)</p>
    <p>What a wonderful father, and a very professional result. <b>tr&egrave;s </b><b>bien</b></p>
    <p>Thank you petestrash :)</p>
    Well documented Instructable and great gift for your daughter and her friend. I think the girls were very happy with this gift. You must be super daddy of the year! I like the details like the stickers on the back side, tumbling to the left and right and the display.
    <p>Thank you very much ! Yes the children were very happy! And it's also a unique gift :)</p>
    <p>All nice but...no explanation about:</p><p>- why 2 arduino?</p><p>- why 2 motor when i saw only one in the finish?</p><p>- the arduino's connection diagram, where is?</p><p>- the explanation of the code...where is?</p><p>- How works the 2 nano togheter ?<br>AM i the only one to see that are missing a lot of things??</p>
    <p>2 Arduino and 2 motors because 2 machines as specified in the introduction (But of course only one motor and one Nano per machine).</p><p>For the diagram I forgot to add it. It is now available at Step 7 (PDF and PNG)</p><p>For the code of Arduino, I think it is sufficient commented to be understandable (it is necessary to download the .INO file)</p>
    <p>you sir are a true artis</p>
    <p>What a compliment! The artist of laundry? :)</p>
    <p>the artist of diy and champion amongst daddies</p>
    Looking forward having grandchildren !
    Really neat design!
    <p>Thank you, I try more and more to improve the appearance of my creations.</p>
    <p>Woohoo, that looks like fun. Great job! Now to build one to fit the kids so they can ride in one.</p>
    <p>Thanks :)</p>
    <p>Very nice construction, bravo!</p><p>Now it's time to build the dishwasher. XD</p>
    <p>Thank you ! It also does the dishes, but only plastic! lol</p>
