Re: [DIYbio] Re: update on the liquid handler

Sure, Tom!

Don't mind our design, is a little not conventional, haha

The idea is verticalize the working area on "floors". So our pippeting bot ended looking like a guillotine, I know.

We still need to implement the x axis as you may see. And we have a problem with the displacement of the z axis connectors wen the pipette moves on y axis - I think that this is because of the belt tightening.
It was used a core H (something like this) for the mechanical control using two step motors.

Tha plan is build another prototype, more traditional, functional and smaller, with a working area for just one 96 wells plate.

OBS: in the video we're controlling using the directional buttons of a keyboard, only for testing.

Hi Otto,

can you post a pic of your pipetting bot? Would be fun to compare designs a little.

Tom.

Nice pippeting bot!

Will Canine from OpenTrons appears to be building a consistent supply chain on China, I gess. This is determinant to put a low cost DIY equipment on the market. You really should consider talk to him.
There is also some biotech accelerators on SF, right!?

I'm building with some friends a liquid handler prototype for 96 well plates too. Hope to finish it next months and share the design online also. :)

I understand open tron is looking for collaborators. Their project was open source. Did you check with them? https://groups.google.com/forum/#!topic/diybio/NhY12FaSMgA.

Howdy,

here's an update on the liquid handler I've been working on. I got X and Y working, still need to do Z and the pump. Yay progress.

The video of the prototype shows going around two 96 well plates, and then going from each well in the bottom row to a small petri dish:

Looking for a co-founder with a background in the life-sciences. Email me directly. You'd have to move to the San Francisco Bay area eventually.

Tom.
