Anyone down to help work on a microfluidics device?
« on: October 21, 2013, 11:36:35 AM »
 A group of mine is starting a biohacking nexus in central florida, and to be the very best, like no one ever was, we need high throughput and automation. This means we need to make a lab. Its not as scary as it sounds, most of the stuff is just simple robots that many of you could easily design. If we dont have the tools to make certain things, I propose we make them for the space, so others can use them as well.

The first little project I would like to kick off the lab gear is a centrifuge. Ive already printed the container that holds the tubes, so we really just need a drill and something to hold it in place, and a control interface with a laptop. should be a piece of cake. I can get the drill and an arduino, if anyone can find or make software for various speed and time settings that would be a huge help. We can discuss a possible meetup.

The second thing I want to make is on the other end of difficulty:

http://www.ncbi.nlm.nih.gov/pubmed/20448870

Making the wafer might be difficult because we will need to make a few devices to fabricate it (spin coater, gas deposition chamber perhaps?) but after that we just need to slap it on a high res lcd and the rest is programming.

adding tubes and pumps and such to interface to other devices would be the next step.

many more projects to come! I also want to document their creation and blog it, as well as post it up to the openwetware wiki. This should be a lot of fun, and revolutionary for biohackers everywhere :D

Hello! Bring me a drill, an arduino, a RTC and an appropriately rated motor controller. I will make you your thing. What rpms are you looking for? Would a Dremel be better suited?


Thanks!

Are you working with Dave Casey or any of the UCF crew?

Pocky, we have a centrifuge somewhere. Cope said Dan left it at the lab. :)

A project that falls somewhere in the middle is this thing:

Are there any tentative plans for those 6' chunks of makerslide that are lying around?

Dan said he left it at the lab but we haven't been able to find it. Also, I've got an 8 foot section of that makerslide in the living room of our house. We forgot it in the corner for a while >.<
I like colors.

For a centrifuge...  how about two test tubes (for balance) that are held in pivoting cradles and hung on a disk that's mounted on a shaft, and then place the shaft in the chuck of a drill press set on the highest speed? 
What's the volume of fluid you want to separate?
What g-forces will you need to generate, or what is a comparable centrifuge you're thinking of?
What are some biohacking projects you'd love to do?

Pocky sounds like a plan. I am with Casey and the ucf crew as well. The centrifuge, to be useful for various things, would need to have variable speeds and variable times. Dremels have well over the nessesary rpm, so they would work great.

Re: the centrifuge, I think I saw it last night on the far end of the electronics bench, behind someone's incomplete project.

If anyone sees something that looks like this, it's the centrifuge.

Also, depending on the status of the laser, there is this: http://www.instructables.com/id/OpenFuge/

Modify the files a bit and you could cut it on the cnc machine.

Found the centrifuge. It's at the end of the work bench.
Note: To improve mood, administer chocolate.

Well, that solves that. Does anyone know anything about controlling a dmd from a dlp device with a computer or hacking windows phones to make your own apps?

1) What is a dmd?
2) Do you have access to the full optoelectrowetting article?
and maybe this article as well? http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=4400117 (Lasers!)
