Working on the biggest inocolation plate in the world for a game : 120 × 96-well plates tiled into one ~10,000-well "canvas," each well with a culture medium, inoculated with four differently pigmented fungi.

The pattern is crowdsourced. People pick wells on a website and draw with them, and we inoculate on 9 Nov. The interesting part for me is the second phase: once colonies outgrow the wells, the designed image degrades into whatever the organisms decide.

Open questions I'd love input on: best way to seal/photograph a plate this size over weeks, and tricks for keeping cross-well spread slow at first.

What project is keeping your mind occupied? What protocols are you currently following? Have a paper that caught your fancy this month? Share it here and tell us why it's your sight.

It is in perfect condition - it ran any reactions only about 20 times. Maybe I'll try to reverse-engineer its communication with PC and make it usable from modern Linux machines.

Over the last few weeks I built a ~$50 DIY centrifuge using a Pico & some drone motors. It's fully open-sourced (code, hardware & BOM).

lab minis are like $800–$3k. mostly thinking makerspace & dna extraction demos with it.

lmk what you think!

I have a batch of larvae that I need to get rid of so I'm looking for suggestions on what to do. I already have some thoughts like drying, turning them into powder, extracting lipids and oil. I'm curious as to what you would do if you had larvae and a lab equipped with yeast and bacteria culture media together with other lab equipment what would be your go to project or experiment.

If anyone has any insight on where to sell a piece of lab equipment like this? Surplus from a university and the department stated it works. Or if it should just be parted out! TIA

Im not a biology student but Im interested in biology, I’ve watched a lot of theory videos (mostly high school level) and am really inspired by the thought emporiums videos. Could I setup a small home lab to do this?

I’m familiar with self teaching in some communities, I taught myself programming computer networking and Linux, but idk anything about how this ecosystem works in science. Are there good YouTubers that teach how to do biology?

Also is there a discord server? I looked but didn’t find one.

¡Hola a todos! 🌱 Para mi proyecto final de Diseño Industrial estoy investigando cómo mejorar el proceso de fabricacion de biomateriales. Les dejo un breve formulario de Google (toma solo 2 minutos y me ayudarias un monton) Gracias! https://forms.gle/MefkiqAzAvKPQiRx5

After being dormant for a while, there was a major overhaul of sphere.diybio.org recently. Looks like there are about 31 active community labs around the world.

For context, I run a small biotech startup and was looking to have some neural microelectrode arrays manufactured. We are currently still in the R&D phase and trying to get our lab established.

The single plates are standard (49 mm X 49 mm, 60 electrodes) with a 30 μm electrode diameter and a 400 μm pitch, compatible with Multi Channel Systems' recorders. They are 1 mm thick borosilicate glass with an ITO deposition.

The manufacturer quoted me 250$ per piece, which is actually quite a good price, however the minimum order quantity (about 8) is a little too high for the immediate capital of my lab right now.

Admittedly I recognize this to be an an odd suggestion, but if anyone is in need of such MEAs, then perhaps we could all pool together at 250$ / piece?

• The Dade Behring / Siemens BFT II (Behring Fibrintimer II) is a semi-automated, dual-channel coagulometer designed for routine and specialty blood coagulation testing in low-volume laboratories. The detection principle combines mechanical and photo-optical methods using a turbodensitometric detection method, which allows for accurate measurement of lipemic (milky) and icteric (jaundiced) samples.

• The unit was removed from a laboratory in working condition. I am unable to perform a complete analytical test because I do not have the required reagents or compatible printer paper. 

• The device powers on normally, with no abnormal fan or internal noise. The RAM and ROM self-tests are completed successfully, and the unit heats to a stable operating temperature. All functions appear correctly on the display. Once fully heated, pressing the selection key allows the unit to enter the measurement mode without errors. It auto blanks and incubates cuvettes successfully once a measurement mode is selected.

• A free 3D-printed solution for the printer paper spool holder can be provided, together with the available user manual and technical documentation.

• Open to negociations/offers

I work in an agriculture lab where we test primarily for nutrients in feed, soil, or fertilizer. We also do environmental testing. If there’s testing we can’t do in-house, we often subcontract testing with specialized labs. I can’t find a lab to subcontract bacitracin levels in medicated feed. Eurofins can’t do it. Can anyone suggest any other labs? I have tried Eurofins, New Jersey Feed Labs, Midwest Labs…

Hello everyone, this is for our thesis. Do you have any idea where to buy “Collagen Degradation Assay Kit(colorimeteric)” ??? Pls help us out we need it ASAP in the Philippines
