There Are 200 Electronic Kits In That Box

Posted on by

If you grew up in the latter part of the 20th century, you didn’t have the Internet we have today — or maybe not at all. What you did have, though, was Radio Shack within an hour’s drive. They sold consumer electronics, of course, but they also sold parts and kits. In addition to specific kits, they always had some versions of a universal kit where lots of components were mounted on a board and you could easily connect and disconnect them to build different things. [RetoSpector78] found a 200-in-1 kit at a thrift store that was exactly like the …read more

Spectrometer Is Inexpensive And Capable

Posted on by

We know the effect of passing white light through a prism and seeing the color spectrum that comes out of the other side. It will not be noticeable to the naked eye, but that rainbow does not fully span the range of [Roy G. Biv]. There are narrowly absent colors which blur together, and those missing portions are a fingerprint of the matter the white light is passing through or bouncing off. Those with a keen eye will recognize that we are talking about spectrophotometry which is identifying those fingerprints and determining what is being observed and how much is …read more

Biology Lab on Your Christmas List

Posted on by

We hope you have been good this year because we have a list to start your own biology lab and not everything will fit into Santa’s bag (of holding). If you need some last minute goodie points, Santa loves open-source and people who share on our tip line. Our friends at [The Thought Emporium] have compiled a list of the necessary equipment for a biology lab. Chemistry labs-in-a-box have been the inspiration for many young chemists, but there are remarkable differences between a chemistry lab and a biology lab which are explained in the Youtube video linked above and embedded …read more

Open Source Laboratory Rocker is Super Smooth

Posted on by

Lab equipment is often expensive, but budgets can be tight and not always up to getting small labs or researchers what they need. That’s why [akshay_d21] designed an Open Source Lab Rocker with a modular tray that uses commonly available hardware and 3D printed parts. The device generates precisely controlled, smooth motion to perform automated mild to moderately aggressive mixing of samples by tilting the attached tray in a see-saw motion. It can accommodate either a beaker or test tubes, but since the tray is modular, different trays can be designed to fit specific needs.

Source code and schematics are …read more

DIY Cryogel Sustains Live Cells

We like to think our readers are on the cutting edge. With the advent of CRISPR kits at home and DIY bio blooming in workshops across the world, we wanted to share a video which may be ahead of its time. [The Thought Emporium] has just shown us a way to store eukaryotic cells at room temperature. His technique is based on a paper published in Nature which he links to from the YouTube page, but you can see his video after the break.

Eukaryotic cells, the kind we are made of, have been transported at low temperatures with techniques …read more

Automated Chamber Passes Just the Right Gas

Posted on by

It sounds like an overly complicated method a supervillain would use to slowly and painfully eliminate enemies — a chamber with variable oxygen concentration. This automated environmental chamber isn’t for torturing suave MI6 agents, though; rather, it enables cancer research more-or-less on the cheap.

Tasked with building something to let his lab simulate the variable oxygen microenvironments found in some kinds of tumors, [RyanM415] first chose a standard lab incubator as a chamber to mix room air with bottled nitrogen. With a requirement to quickly vary the oxygen concentration from the normal 21% down to zero, he found that the …read more

Motherboard meets the scientists and staff that make this place a leader in research and scientific exploration. Continue reading Inside the Dark Matter Lab Buried Over a Mile Underground→

Tiny Tunes On An ATtiny13

Posted on by

When you take a microcontroller class in university, one of the early labs they have you drudge through on your way to, promised, mastery over all things embedded, is a tiny music generator.

It’s a more challenging lab than one would expect. It takes understanding the clock of the microcontroller and its sometimes temperamental nature. It takes a clear mental picture of interrupts, and is likely one of the first experiences a burgeoning designer will have worrying about the execution time of one of their loops. Also tables, data structures, and more. It even requires them to go out of …read more
