I visited a friend in San Diego. first thing I noticed was his cutting board. Just a Boos Block, but it’s been modified. He said his neighbor put some electrodes in it and sent electrical current thru it. He then filled the gaps with a blue colored epoxy filler.

It’s a total trip.

Just wanted I show you. It looks like lightening strikes.

If you search for "Fractal wood burning" on the interwebs, you'll soon find titles like "DO NOT TRY THIS AT HOME" and "DEADLIEST CRAFT HACK ON THE INTERNET".

Wikipedia says:

It has gained notoriety due to numerous incidents of death or severe injuries when people have attempted it at home, with at least 33 people having died between 2017 and 2022.

yeah that is clear, I was just wondering HOW much of either and that is clear now, nothing that extravagant IMO (yet not for folks with moist hands and little HV knowledge)
 
33 people in the US alone have died from doing this in the last 6 yrs...
 
Lichtenberg burning was a bit of a trend for a bit. The dangers involved weren’t widely discussed initially but now most mentions come with a health warning so it’s become less popular. Everyone has jumped on the resin bandwagon instead
 
Wow if 'unsealed' begs the question - Why would you want a fissure in a wood grained cutting board for all bad things microbial?

2nd obvious question - if 'sealed' - Why would you want a random hard epoxy with your knife edges (Boos or not)?

It is definitely 'cool looking' and I have seen that kinda thing up close ... but better a serving tray (IMO) for me ...

I do love the segue of the discussion for a DIY project ... just like making your own "anthrax" or "C4" ... just 'all in good fun' ... but consequences count ...
 
Why risk it. There are enough harmful substances we involuntarily come into contact with without creating our own......

According to 3M "epoxy resins have been shown to contain carcinogenic, mutagenic and reprotoxic chemicals (CMR substances) that can be dangerous to the people who work with them. They contain chemicals that have inherent properties that can cause cancer, alter DNA or damage reproductive systems. For example, the isocyanate hardeners in polyurethane resins are suspected of causing cancer (CMR category 2)."

Tonight, I used my hand to wipe the swarf off my stone. Now I have a micron-wide bit of wire burr embedded in my thumb. I got most of it out with sticky tape, but I can still feel the part that’s left. Yeesh

Reminds me of the time I got stuck in a bathroom with no TP but a GI tract full of extra-spicy chili. All I had was a 100 grit diamond sharpening plate...

...when I got home I had to work through a progression of stones up to ~17,000 grit to get rid of the scratches. Could cut through paper though, which was a cool party trick.
 
I would not want to mix epoxy and food (or most other artificial resins for that matter), just thought that the mix of high voltage and wood is looking sweet.

I personally have four different types of epoxy in my garage. Which one?

so you're all set, I'm sure you have an old microwave lying around there too ;-)

I’m not an epoxy expert like you all. I know mine are not good safe since I use them in my automotive stuff and sidewalks.

I did just Google food safe epoxies and they do exist.

I don’t understand the microwave reference.

Apparently one way to produce the extreme voltages necessary for this is to take apart a microwave.

Thanks for clarifying
