Arranging 441 Drops of Water In A Square

My invention folds used cigarette boxes into oragami doves. What now plate of water drops?
 
I like the part where nothing happens for the last 30 seconds of the video, I love that I had to sit there waiting for something to happen only to discover i could have stopped that video (or they could have) much earlier.

Neat indeed, but it's just a modded cnc machine.
 
No top-down view of the finished square? I wanted to see how precise it was. Oh well...
 
Piss your name in cursive, Squirty Machine, then you can hang out with the big boys.

Not very. You can see in the first row a few drops further from their neighbors than the others. That's probably why they avoided the top down view.
 
Didn't I see something like this in Willy Wonka and the chocolate factory back in the 70's? Pretty sure it was squirting chocolate.

Of course if he sells it someone will try to use it to put there visine eye drops in.
 
Heck, I have a machine at work that does the same thing.
You can buy them from a variety of manufacturers.
I typically use mine to add a specific volume of my samples into a 96well plate (12x8) and can program which of those 96 wells should get sample added and which shouldn't etc...
It will also do 384 wells (but I hate working with those.. so typically stay with the 96 well).

Hate to say it, but the guy wasted a ton of time and money on a machine that is less accurate than something he could have purchased for the same money already made and with more features.

Tecan? Hamilton?

Have you make the trip to ALA in January? It's Mecca for lab automation equipment. It's in San Diego next year. I'm so glad they moved it our of Palm Springs.

I work for a company that manufactures tube handlers. This January we introduced liquid handling to our line.

It's like Chinese water torture... perfected.

It's how the Japanese would water torture somebody. Overly engineered machine to perform menial tasks. They strap you to it if you try to cheat one of their millions of automated vending machines.
 
A grid of 21x21 water drops. What's so cool about that? :confused:

How many fluid ounces in 441 drops? :confused:
 
As a CnC hobbyist, I found that video interesting. It looked like there was constant suction in that syringe and the suction would cut off for a split second to allow the drop to ... well ... drop.

I would be more impressed if it was a traditional syringe and the guy had used the Z-axis to depress the syringe every time.

I was thinking the same thing. I didn't really get a feeling of scale but it seemed like if this machine was going to inject me with medicine, the small little ....umm...variations might cause it to unintentionally miss my vein. I don't have that large of veins to begin with.

the gantry is likely very accurate. surface imperfections on the substrate likely shifted the bubbles some.

even a speck of dust would cause the bubbles to orient one direction vs the other. the video wasn't shot in a clean room.
