I need help 3d Printing out a couple of high quality prints for a bio 3d printer

by Sean greenwood

Hi I need some help printing out a couple of parts for a syringe pump that allows me to extrude my biopolymers. I tried my hand at it but no luck it was good for the first couple of layers but soon got warped and didn't look right. The pegasus horses is amazing if I could get that kind of quality that would awesome!

Re: [sudo-discuss] sudo-discuss Digest, Vol 48, Issue 1

by Elizabeth W. Biddlecome

SudoBike?!?!?!!!! I don't know what this is, but it sounds pretty neat! I sure do <3 SudoRoom & SudoMesh, and bikes. Looking forward to having some time to regularly visit again!!! I've been saying how bad we need a folding bike over here biweekly for awhile, so if there's no immediate use/room, I'd be ecstatic to house & attempt to upgrade it for however long. How often is the Sudo/Omni wish list is updated? In my nonexistent spare time, I would love to make a little web app* that community users could update with various needs/wants/haves. While I don't have much in the way of spare time right now, I do have a lot of potentially useful "assorted randoms" on hand that I'd be happy to contribute. Miss coming by; hope to be able to come soon & check out all the amazing things everyone has been up to. Speaking of which- how does Sudo feel about field trips? I'm working part time with an org who is teaching CS/Intro to Web Dev in public high schools. We are piloting in the schools with the highest number of free & reduced lunches. In addition to our attempt to bring CS education to economically marginalized communities, we are also attempting to disrupt the tech divide and school to prison pipeline. One program is in Oakland this semester. We take field trips, and I think a hackerspace trip could be an invaluable experience to include, along with all of the intimidatingly glossy, alternate universe style corporate digs we will visit. I'd like to bring my class to Noisebridge, as it's a < 5 minute walk to there from school and NB allows field trips. However- nothing against NB, I fully support them/think they're awesome, and these may have been totally isolated incidents involving non members- I have some concerns due to past personal experiences there. Since our classes consist largely of underrepresented minorities in tech (including myself and the Oakland instructor), I might feel more comfortable bringing them to Sudo/Omni, if we could arrange it. Does Omni/Sudo have a field trip policy &/or has this ever happened? They are small (20) classes of high school kids who are great to be around (and more respectful/mature than a lot of adult, professional engineers I've met), so I don't think it would be a huge burden on the space. Likely, our only ask would be a volunteer to show us around and explain things. Figured I should ask before bringing up the possibility to any of the other instructors. So grateful for everyone's hard work in keeping this community (and similar endeavors) going & growing. best, Elizabeth Biddlecome *I do have something I made over the past couple of days, in the course of a Sisyphean ordeal (I mean "job search process"), where I spend days without going outside or adequate self care performing a lot of uncompensated work. I think I could actually make this into a nice little SudoApp, without a ton of complications- plus I specified MIT licensing, of course. On a personal note, it would great to direct at least some of the massive amounts of energy expended throughout this frustrating hamster wheel process toward a positive end. There may be/probably is something already in place for Sudo/Omni that I don't know about, other than the wiki wishlist pages, IRC, here etc. Sent from my iPhone > On Oct 2, 2016, at 2:41 PM, sudo-discuss-request(a)lists.sudoroom.org wrote: > > Send sudo-discuss mailing list submissions to > sudo-discuss(a)lists.sudoroom.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://sudoroom.org/lists/listinfo/sudo-discuss > or, via email, send a message with subject or body 'help' to > sudo-discuss-request(a)lists.sudoroom.org > > You can reach the person managing the list at > sudo-discuss-owner(a)lists.sudoroom.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of sudo-discuss digest..." > > > Today's Topics: > > 1.

What are your October goals at SudoRoom?

by Romy Ilano

I have a small amount of time to drop by SudoRoom and Counter Culture labs this month. I decided it's would be fun to write some October goals. Here's a picture to boot! Habitual - every time I go to SudoRoom and back, leave something creative behind like a drawing - say hi to everyone and remember we are all creative fun animals - face to face is so nice! And remote will never quite replace that - See what cool projects other people are working on - facilitate the creativity between the spaces (especially counter culture labs, sudoroom and then be inspired by the interdisciplinary creativity from folks like Ceremony who are doing a science and art meetup - get the word out on SudoRoom fundraising So that's what I've been doing. But for longer term projects: October goals at SudoRoom - getting ready for Snowboarding - going to SudoRoom to understand how my snowboard is made, understand how to repair things, understand how to fix things if I need to (even if I don't), potentially donate snowboard equipment to SudoRoom for others to use as long as it's not a storage space issue - Jump start the old accessibility projects - a few years ago I broke my ankle, and had a lively discussion with many Noisebridge and SudoRoom folks about cheaper alternatives to current medical hardware, which tends to be proprietary and overpriced, and even ugly - somehow start again the Art & MRI project that we had. We had some discussion and it tapered off. I'd like to make a book or something. - make a few SudoRoom stickers - see if anyone is doing some kind of virtual reality education project at SudoRoom - do some kind of iphone or ipad pro project involving accessibility. This is my handicraft by day and I'd rather stick to one thing instead of being distracted by ten million platforms. That being said, there are an amazing amount of accessibility APIs with apple and I want to use that knowledge for good So everyone, what are your October goals? It's so refreshing seeing old faces again.. Sent from my iPad

Donation: folding bike this month? Do you have space?

by Romy Ilano

Hi, I have an extra tern link folding bike. The gears are janky but it's functioning. In the long term the gears will have to be replaced but that would be more than the cost of a new bike. However, the bike is working and might be of use to folks. Is there space at SudoRoom and CounterCulture labs for this bike? I think it might be a useful addition to the SudoBike! It folds, so when folded it doesn't take that much space... ============================= Romy Ilano romy(a)snowyla.com
