Katie has come through again and sent me something wonderful to tear down. In 1995 windows and x86 IBM clones were cornering the market for home computers. But not everyone had fallen in line just yet. The Acorn A7000 was one of the last holdouts, and what an impressive machine it is!

    I like a "live edge" timber too! I may add a little one too my next trial (I have some apple off cuts somewhere I think).

    I can't hear a member of may family say "I'll have a Tea please" without me adding "Bob" on the end of it!

    I'm doing to try another small sample with come embeded electronics to see what works and what doesn't. I'm hoping capacitive touch works through the resin hapily. Also -  I have children, fingerprints are inevitable!

    The PCB table-top looks good but that single strip of lighter wood at the top looks a bit out of place to me.

    I quite like the 'river' resin tables where the rough edge blends into the epoxy and you have the part opaque / part translucent effect, something like:
    https://www.youtube.com/watch?v=iwqmPgebB00

    The hexagonal interactive touch table also looks good and has the bonus of being interactive. 
    ( Add some letters an it perhaps would be ideal for fans of  the 'Blockbusters' gameshow -
    "I'll have a 'P' please Bob..."  ["...the toilet's upstairs, last door on your left..." boom boom ] )

    I guess there is nothing stopping you from having the interactivity aspect around the edges with the PCBs in the centre or perhaps even the other way around.

    However, with interactivity, comes dirty fingerprints... and scratches.

    In truth, if I had the time, budget and skills, this is the table I would like to emulate (to some degree).

    Skip to around the 11 minute mark if you can't spare the whole 15 minutes!

    Maybe with a bit more of this mixed in:

    Good spot! I don't wan't to claim that I have any type of condition, but that would bug me somewhat!

    "...does that mean that the smaller table isn't round..."

    Correct. That's something for you to improve on on your design Wink

    You can see it here against the round skirt that raises up:

    Although some tables appear to be the opposite - they are round when fully closed and have 'flats' when opened up.

    They are indeed awesome - and I would gladly have one (although building one may be a step too far for my carpentry skills, or lack thereof).

    However, there is one thing that has always bugged me slightly about these, and that beautiful video has made me think it is probably right. As the radius of the two tables is different, and the arc length for the "larger" one is correct, does that mean that the smaller table isn't round? The fact that they didn't show an overhead shot of it completely assembled in it's small shape makes me think this is right?

    Bonus points if you can combine an epoxy resin table with a Fletcher Capstan table... Wink
