Make a Led Tron Desk and Led Tron Clock





First excuse me for all my english mistakes...

Here is my Tron desk and Tron clock.

I should create my desk and why not create a special one :)

It was a very very VERY long work...I learn so much thing, it was fun and the result is really pretty!

What I need for the desk :

- oak wood plank (3 planks : 20 mm * 30 cm * 2 m) => Top desk

- spruce wood plank (3 planks : 20 mm * 30 cm * 2 m) => Bottom desk

- one wood router

- resin

- one ledenet (wifi - led controller)

- a 12V/10A alimentation

- a 5m led strip

- wood wax

- black pen

What I need for the clock :

- oak wood plank (20 mm * 30 cm * 2 m)

- one wood router

- resin

- a 12V/10A alimentation

- an arduino

- a 12V/5Vtransformer

- a led strip adressable WS2812b

- a RTC DS1307 module

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: The Idea

No how I get the idea?

When I saw this resin table, I decide to make my own.

But not with a river, I am not a fisherman, I am a geek!

I need something pretty, that every geek recognize and LED compatible.

Ok let's go to Cortana...Good idea but it is definitly too WAF expensive!

And why not the Tron motobike? => Perfect :)

Step 2: Drawing

Fisrt, make a good drawing.

For this I use Gimp and print the drawing at the real size.

Here is the construct schema and how all parts are assembled.

Step 3: Board Assembly

I need a 186cm*90cm desk, but there is no plank with this size.

Ok, let's go to create one.

Use the router to make some groove.

Then introduce a small wood piece, and glue the plank.

Maintain with some strap.

Step 4: The Router

This step was very stressful because a mistake is not allowed!

The 2 circles was "easy" to do with the router, but the curves was more difficult to achieve.

I use the real size drawing to mark the circle center.

Then, like Jules Cesar said : "Alea jacta est" !

When this is done and you don't make a mistake, use some sealant (good word ?) for the wood holes.

Step 5: The Led Strip

This step is very simple, there is no difficulty.

You just have to check that the led strip will be a the good place :)

Step 6: The Resin

This step was stressful for me.

It was the first time I used resin and perhaps the result would be bad...

First I need to evaluate the resin volume. I used the "rice unit" for this evaluation.

A good idea at the beginning but in fact, I underestimated the resin volume :(

Then you just have to fill the holes with the resin.

When it is dry, use a sander.

The sander step is really long but the result is very beautiful!

Step 7: Plank Drawing

We are close to the end :)

Now it is time to draw the motorbike.

For this step I buy 6 differents black permanent pen to be sure to have the best :)

Then, it is not diffcult but you have to be patient and do not shake!

Step 8: Wax Finition

The wax finition

Step 9: Hacking the Wifi Ledenet

The wifi ledenet was controlled by BRGLight andorid application.

Ok, it is good and very usefull, but I want to control it with my line code.

I use tpacketcapture to capture the transmission between the BRGLight aplpication and the ledenet.

Then I use wireshark to analyse the captured packet :

- Protocol UDP

- Data : c9 02 00 0a ff

Let's simulate an UDP packet with Eclipse in Java (see

OMG => It's work!!!

With a python program on my raspberry pi, I can now control my desk.

For example, the default color is red. But when I receive a new mail, the desk becomes green.

When someone phone to me and I didn't answered, the desk becomes blue :)

Step 10: Bottom Tron Clock

The clock is only compose with circle, and circles are easy to make with a router.

The most difficult is to determine the circle diameter.

I need 120 Leds for the minutes, 120 leds for the seconds => diameter 26.3 cm

I need 96 Leds for the hours => diameter 21.2 cm

Step 11: Top Tron Clock

The difficulty of this step is in the little circle, they are really slim...

The resin phase was a simple formality:)

Step 12: The Tron Clock Circuit

It is not really difficult.

The code is a little bit more funny to write (see clock.ino file)

I have a bug at 0h and 12h. Need to fix it!

Step 13: The Dock Station

Once again, circle, circle, circle...

Step 14: The Tron Clock Result

Perfect :)

Step 15: Conclusion

It was very long to make but very instructive for me :)

I am really happy to have a geek desk!

Now my son want a Star wars desk and my girl a Hello kitty desk...

    suuuper cool. especially the clock. I have few questions and maybe a tip.

    the resin is transparent? or you added somenthing in order to make it opaque? or it's gust sanding?

    after a year or so all the leds are still working? I've bed experience concerning ws2812 reliability, so I would plan a way to change them If they broke. I think you can't because as far as I've understood you poured epoxy right on top of leds, right?

    the tip: I would use an ESP8266 and a NTP client to set time, so you don't have to care about daylight time saving, leap year and so. I will provide you code soon because I'm going for this right now :-)

    by the way nice work

    Looks great. Thats some great work by hand.

    Hi, it's a very good job. And I'm inspired to do a similar work.
    A question: on the desk, did you have used a led strip 60led/m or 30led/m?

    That's pretty awesome, given me a great idea for something Iron Man related.

    A couple suggestions.

    1) el wire would also be an easy install.

    2) to set up the circles and make them easier. You can set a solid round bowl in place to use as a guide. For the curves if you make a template out of a thick stiff cardboard. And use it as a guide.

    When using guides for a router make sure to calculate the offset distance for the routers guide.

    Thank you for suggestion.

    I don't use a guide but it was a mistake, if I have to remake it, I will...

    Also using something like a dremel with a router head for the body and mix glow in the dark resin for everything. Go over all the lines with it.


    Reply 2 years ago

    Np I'm an old redneck. I do a lot of random stuff like this

    Also having a bit of scrap to pre test your guide on to make sure it does like you want.

    Excellent Project!!!

    Don't apologise for your English - I am English and would be happy to speak any other language as well as you do.

    Wow! I can't believe you routed those lines by hand. It looks great!

    OK, I'm very confused between step 4 and 5. Does the project consist of two planks? The bottom plank you're using to mount the leds, then the top plank with the cutouts is mounted over the bottom plank?

    Then in Step 5, I'm assuming you're only filling the routed areas in the "top plank", not filling all the way through to the led plank underneath? If so, what are you using as a non-stick backer to pour the acrylic? Looks like you're using melamine in your trial piece is that correct?

    If the acrylic is only being poured in the top blank, how are you mounting the bottom plank to the top plank, or are you just using the surrounding walls to keep the two in place? It looks like you maybe used a piece of trim to join the two boards in front?

    You are right, a plan is missing. I had one in the step 2. I hope it will respond to your question :)

    Yes there is Two planks : Top with resin and botton with Led.

    Like this, is led are break I could easily change it.

    For non-stick backer I use "baking paper" (not sure of this word...=> "papier cuisson" in french) =>
