Circuit boards with lights in epoxy in a table

Circuit board table in 10 steps Step 1 The Idea. putting boards like these in epoxy in a table ..but.. .. what table? at last I found this table online the modern steel legs will go well with the boards Step 2 Preparation. the wood of the old table was discolored and the steel was dirty so with paint stripper I removed old layers of varnish (I used a scrape card for that) and I cleaned the steel the backs of the boards had to be really flat first I tried to remove components with a soldering iron but the fastest way was with pliers Step 3 Making room. mmm.. how would I be putting the boards in? I mean, in what shape? I chose the simple strip shape I cut that shape to depth with the saw .. to about 25 mm I took out a 25 x 4 grid with the router the remaining blocks, I chiseled out big pieces with the grain of the wood the rest sideways and after cleaning it was ready for.. Step 4 Putting the boards in. I didn’t want to see any wood in the small spaces next to the boards so I put in this aluminium tape then it was just a puzzle here and there I had to .. .. force a board down with a screw because the middle name of my workshop .. .. is ‘dust’ .. I figured I had to make a tent before pouring epoxy Step 5 Making a tent. nothing fancy, just two tent-shaped ends connected by wood on the sides strips .. .. covered with garbage bags some boards were still loose for the following step they needed to be fixed so this was the first pour with epoxy last chance to position the boards Step 7 Putting in the LEDs (that are no longer LEDs 🙂 I wanted lights to light up but without electricity .. no cables or batteries .. nah .. so I thought of fiber optic cable and I took a normal LED drilled a hole in the bottom broke off the wires .. and stuck a fiber cable in then I drilled holes in the boards and stuck the (glued) fibers in this block with a hole .. is the focal point for the fiber cables I pulled the fibers through .. .. glued them in .. .. and cut them off funny: you can see the colors of the LEDs just to make sure .. I poured in the LEDs so far, so good .. on to .. Step 8 The Big Pour. witness .. the pouring of .. 7 liters epoxy the epoxy revealed .. the table is bent in the middle so I had to pour extra at the sides Step 9 Sanding don’t ask me why .. .. but I recorded all of the sanding so now I know .. .. it took me a total of 2.5 hours with 60, 100, 180 and 320 grit Step 10 Finish the original plan was .. .. to sand and polish the epoxy instead I decided to pour an extra layer I’ll explain later why I sanded the wood one last time and gave it some coats of Danish Oil>The End Result Epilogue So? Success or Fail? well, opposite of what you might think after watching this video the table was a fail What? Why? Somewhere in the process, and I’m not exactly sure where, the epoxy got not mixed well enough. That resulted in sticky soft spots and very ugly spots wait, let me show you Couldn’t it be repaired? that’s why I tried to put another layer over it all – what you just saw in the ‘finish’-part of the video but that didn’t help at all there were so many soft spots at the sides, that the sticky epoxy kept crawling up and out so not only were there ugly spots IN the epoxy, the table being permanently sticky, made it as good as useless Bummer! Yeah, I was quite upset by this, because 95 percent of the epoxy is fine and it is very nice to look at the many details of the circuit boards and to play with the lights What now? well, I guess I have to take my loss and see it as a learning thing What will you do with the table? I’m not sure yet. I’ll keep it for now and think about it. really getting it right would mean to make an extra groove at the sides, between the wood and the epoxy, with a router or a saw and chisel the failed epoxy out that would be a lot of work, so .. I guess I’ll sleep on it for a while Although the table might not be a complete success, just maybe you learned something of the video, or maybe you found the video entertaining.

  1. If you have something sticky leaking through a jar lid, what do you do? You seal it up.

    Bond a glass top to the table so that it is air tight (And epoxy tight.)

    To avoid it spreading, make the glass only cover the center, with a routed perimeter in the wood around it where you create your containment seal.

    Could even work as an accentuating line.

  2. Processing epoxy in this thickness requires consistent quality every time. Not easy to calculate for this amount. the next one gets better 🙂 Thumps up

  3. Цікав, але я б не став би бракувати хороший стіл, тим білье мертвими платами…

  4. Superb and u had find another way of E waste usage in this superb way and led will work by finer so there is no shorting no need to worry of led replacements this way E waste will be used in all type and dedigns not only table but walls bathroom floor etc 👍✌️08 oct 2019 India 🇮🇳

  5. I did something similar for my coffee table with the help of my local carpenter. The idea was sustainability, so, we upcycled all the old Mother Boards, Raspberry PI kits, etc, screwed them to the table and covered it with glass instead of epoxy.

  6. Good idea, I play with epoxy as well. But to my taste the constrast of the wood with hi-tech electronic board is a bit of a clash, I would use something else than wood, may be Hi-gloss black support. I would add a led strip hidden in the table to shine through the edges.

  7. would some extra heat cure the epoxy? or a chemical catalyst? or as other said, glass top, with glycerin to make a good optical connection with the wood and epoxy.

  8. Hi, Dude this table is amazing.
    I had the same idea to create a table. It's a pity that you have failure project :/ so sorry
    Anyway almost great job. Regards

  9. Like many suggested put glass over is a good idea, but might protrude too much, another option is take Clear Lacquer rattle cans and go over that a few times that might solve the stickiness of the epoxy just not sure if it will flake after a few months, worth a try.

  10. I had this same problem on a project and discovered that the mixing portion is really important as well as doing multiple thin layers vs a few thick ones. I'm also assuming that your environmental conditions were spot on as well, temp, humidity, etc. Unfortunately I didn't find a way to repair the soft or blemished parts :(.

  11. sicky, doesn't that mean not enough hardener ?
    I would have thought you could brush or spray on some hardener and let it fix the soft spots, then sand it down and lay over a new coat over the whole thing.

  12. Там должны быть MB Asus Rampage, взяли самые невзрачные-некрасивые платы!

  13. Most powerfully desk on the world 😀
    The fastest improvement is tempered glass (maybe little smoked) laid on liquid epoxy but mixed well and subjected to vacuum to get rid of air bubbles, or the glass can be slightly dull minimally and this masks all the flaws of the thick layer of the previous poorly mixed epoxy

  14. Heat could cure it, i had the same problem with some of my carbon parts (way smaller) and put them on the radiator for a while…it did help for my parts……so maybe try to gently apply some heat to it.

  15. Hi, I would advise using a 1 component Polyurethane clear / glossy product and paint over the epoxy. You can buy this at most hardware stores. It might help trying to gently scrape as much of the uncured epoxy without going to deep! This often helps. greetings from

  16. Wait those were working or dead boards ?it's nice but lights could be done better with a proper pcb led that are quit clean bright and those boards have led that can be rewired to and a proper microcontroller will make then look like they working especially the Ethernet, power hdd LEDs and more

  17. I was just thinking …..this is what the world needs , some liquid plastic to fill all those voids on earth we haven't covered in plastic drinking bottles . Brilliant !

  18. Epoxy is such a spoiled princess to work with, but nothing can match the performance and capabilities of epoxy if you are doing it right.

    One method I've learned and practiced religiously after one to many projects failed in the same way as yours is to first measure as exactly the as I can and mix in one beaker, then pour the mix into an empty second beaker and use a new/clean spatula and mix it a second time, for just as long as the first time.

    If you leave the beakers with the epoxy leftovers to cure you can feel a significant difference between the two beakers when you touch the cured epoxy, the walls of the first beaker will be a little sticky,second beaker will be completely dry to the touch.

    I do the two mixing vessel thing both for when I do casting with epoxy as well as any carbon/glass fiber epoxy-lamination stuff, but with normal consumer grade epoxy glues I don't bother.

    In my limited experience, the glass-clear types of casting-epoxy seems to be extra sensitive for insufficient mixing if that is any comfort in your case.

    Nevertheless it was an epic build and stellar results in every other area except for the mixing epoxy. 😎

  19. They make an epoxy that puts a glass finish on wood and other media… Cover the whole surface not just the boards….

  20. Where the epoxy meets the edge of the cutout looks rough, this is only my opinion. It looks outstanding in lowlight.

  21. Still looks good to me. Ive learned that leaving in the sun light should help dry it out or use a router to cut down the layers to just above the components and start again.

  22. put a piece of glass over it, there is a fix for sticky soft spots. you cant do anything more. its a waste to throw it away.

  23. How far to the edges did the stickiness reached? Maybe you can still use the table for something if you just use the edges maybe?

  24. Amazing! the effect is superb though couldn't you use those LED xmas tree lights instead of the fibre optic cable?

  25. I think its great could you get a piece of glass and cover the top of the table? Might be a good way to use it until you can correct it or build another one.

  26. I love epoxy! But what does it smell like? Can you finish a floor with it? I think it dissolved something in the circuit boards and that made the sticky areas? (And surely environmentally friendly…) It’s eerie how much it looks like a business park. A piece of 21st century art.📱

  27. good video, sorry for the fail,but we learn by doing, personally I would have just cleaned the metal , stripped the old varnish, reapplied and been very happy,but i see your vision in this

  28. May you should have tried 2 small end tables first. Been trying to figure out what to do with all the circuit boards I have. The real problem I have is over 100 monitors.

  29. EDIT: someone else said it first, but I totally agree: Why not just put a piece of plastic-plexi or real glass over the whole table? That will cover the sticky parts up AND allow you to keep all the work you did to see the cool lights and circuit boards without having to do all kinds of crazy long extra tedious work to try to fix it 🙂

  30. I like this idea but think maybe instead of the resin you could have set a glass sheet flush with the table and achieved the same result.

  31. why the hell do you place the processors upside down on the boards? Just to see them pins? Makes no sense at all. Would be cooler to recognize the old hardware under the epoxy

  32. Solution To end this stickyness U can coat the top Layer with smashed Bar B Que Charcoal .or U can use any cheap CornStarch from walmart even great Value and Dab it on all over with youre hands because of u use a brush it might cause groves and lines in the part u are trying to dry. After u let sit the powder cornstarch or charcoal dust will soak up the stickyness then u can Boff the epoxy with turtle wax rubbing compound
