I made this 100x100 mm nanopositioner is also for high resolution cell monitoring
with auto focusing function
what is the minimal repeatable positional accuracy you get with that?
Very nice on the nanopositioner for high resolution cell monitoring! Are you familiar with the LabSmith version of that?
I didn't use interferometer to compare on this system...but I have other in another system.... let me find it
LabSmith? no....sorry :)
@Edwin Hwu :-) I've been wondering over the years if there are parts available in the HD and disc players to make a maybe Michelson or other interferometer design based non-destructive sample NIR-Vis-UV spectrometer. Also, regarding previous linear CCD... more for destructive sample LIBS work.
This is the comparsion between MicroE encoder and interferometer
@James Finch I need to study the system you mentioned ;)
Hi! I'm with quub, a pico-sat startup. Scrolling through the past messages, looks like these techniques will be perfect for some of our ideas 😎
@Nathaniel@quub.space do you have website? :)
cool! pico satellite...
LabSmith is a company started several years ago by Kirsten Pace, a former grad student of John Wikswo and Dave Cliffel at Vanderbilt. I was one of the beta testers on their microfluidics education kit. Your microscope looks pretty comparable to theirs. They sell it for around $8000. I think yours is more precise.
I am not sure if the nanopositioner will work in the space...but I guess yes since nikel and iron are different metal ;p
Pico-sat. I am familiar with nanosatellites, but pico!
I think the miniaturized rotary piezo motor can help also ;)
@Edwin Hwu yep! https://www.quub.space/
@Edwin Hwu The last work I did before needing the spy cameras and other remote sensing devices..., :-/ ..., was regarding chemometrics, NIR spectroscopy, FTIR microscopy and hyperspectral imaging. Somewhat related to my and other articles in this addition where I did publish while at Perrigo.
https://www.americanlaboratory.com/1413-Issues/37116-October-2008/ I have to go. Thank you for sharing your work! So much wasted resources that can be put to great use! Very thankful you and everyone who is, are sharing your work.
Reminds me that "SpaceBornUnited" conted me to use cell culture disc contain human embryo in to earth orbit
Here's a prototype 2x 3u deployer module we did last week: https://twitter.com/quubspace
These things are TINY
@james welcome :)

cool! :D
Finding out about the microE encoder by itself made today worth it. We need to collaborate more often. It was a pleasure meeting you @Edwin Hwu!
@Prof. Jim Brenner same here! :D
Actually i am also into micro/nanoscale 3D printing
Cool! nano printing is going to be a major revolution.

Using nanopositioner + Blu-ray optics...
Is atto3D actually available?
not yet...they are prestartup...recently we are applying for 1.5M DKK funding ...
and what was the resolution
Hopefully this and its links will help you with your teaching: https://www.engineeringunleashed.com/card/2167. I have a lot more, but that is a good gateway.
The resolution is 6xx nm in XY, micron in Z...hah
That was done with the xbox head right?
so I can access if I register right? :)
That resolution is probably good enough for bioprinting. 30 microns is not really good enough, but one micron probably is.
Just register with KEEN.
okok! Thanks!
Atto3D is mainly for Danish hearing aid industry....they found out the commercial system has 30+um resolution...not enough for small parts
Sorry, engineeringunleashed.com is the web site for the Kern Entrepreneurial Engineering Network (KEEN). I am one of their community catalysts and am largely in charge of their making initiative.
KEEN is basically the funding for my teaching initiative, including the maker education textbook.
@Prof. Jim Brenner thanks a lot :D
@Prof. Jim Brenner so you have many students interested in your course, cool! then we have manpower ;p
Thank you! I only have 10 students in my making class in the summer because it is summer. I teach around 40 in my materials characterization lab, 60 in my nanotech lecture, and usually around 60 in my Basics of Making class. I offer these classes on a 2-year rotation. https://fit.instructure.com/courses/265730/files - Go to Basics of Making near the top, and then all of the folders that start with M or N are for the other courses.
haha...I will try another name
Try "Other" for affiliation with regard to KEEN.
okok!
Other than the 7 axis unit have you looked at any other projects in nano assembly?
Did "Other" actually work? If not, e-mail either Becky Benishek (bbenishek@engineeringunleashed.com) or Michael Johnson (mjohnson@engineeringunleashed.com), and we'll get you in there. What you have done with spinning your inventions off as a small business is exactly what this site is interested in.
@placethesundontshine yep, I have 18 axes 6 probes probing station
I'm in!

It looks like you are in to KEEN.
https://www.youtube.com/watch?v=LFEBZuy0R-w
I like engineering....not basic science....it's boring to see atoms jumping ;p
very interesting is that probing or are you actually manipulating devices with that unit?
@Edwin Hwu thanks for your input. I'm looking forward to see the rotary actuator being published/open-source!!
I have to leave
Welcome! :)
@placethesundontshine that's a system planning for TSMC ;p
hmmmm my interest is in photonics assembly but have much smaller pockets than TSMC
haha....since I open source them in the paper...you can build one at low cost
Approximately how much did it cost to make the cell culture bioreactor with the microscopy (time and Euros)?
I may teach design and build cours in DTU next year....the KEEN could be very helpful :D
109 Euro ;p
still writing....I am using nanopositioner template
@Prof. Jim Brenner let's keep in contact! I need to run!
Those micromanipulators are really cool!
Buy everyone! :)
Thanks @Edwin Hwu
https://engineeringunleashed.com/card/1791 for The Design Process. I am editing my Canvas course site that I sent earlier to include more detail on how to guide the design projects. Teaching the skills and the mindset are not all that difficult for a maker, but managing the projects is a challenge!
I enjoyed meeting you @Edwin Hwu
you can find me on hackaday as well :)
Hi Edwin - Any chance to see your stuff in action out at
DTU?
