The Microlab is a do-it-yourself Controlled Lab Reactor (CLR). You don’t need a CLR to make chemical reactions happen, but it makes the process of synthesizing compounds from precursors much easier and more reliable.
The Microlab is designed to load a recipe for a chemical reaction, then automate the temperature control, reagent addition, and stirring that are needed. It is designed for small-molecule organic chemistry to make certain medicinal compounds in your own home or workshop.
A while back Joe Fitz tweeted about the S8 data line locator1. He referred to it as “Trickle down espionage” due to its reminiscence of NSA spying equipment. The S8 data line locator is a GSM listening and location device hidden inside the plug of a standard USB data/charging cable. It supports the 850, 900, 1800 and 1900 MHz GSM frequencies. Its core idea is very similar to the COTTONMOUTH product line by the NSA/CSS [1] in which an RF device is hidden inside a USB plug. Those hidden devices are referred to as implants. The device itself is marketed as a location tracker usable in cars, where a thief would not be able to identify the USB cable as a location tracking device. Its malicious use-cases can, however, not be denied. Especially since it features no GPS making its location reporting very coarse (1.57 km deviation in my tests). It can, e.g., be called to listen to a live audio feed from a small microphone within the device, as well as programmed to call back if the sound level surpasses a 45 dB threshold. The fact that the device can be repackaged in its sliding case, after configuring it, i.e. inserting a SIM, without any noticeable marks to the packaging suggests its use-case: covert espionage.
“I thought using loops was cheating, so I programmed my own using samples. I then thought using samples was cheating, so I recorded real drums. I then thought that programming it was cheating, so I learned to play drums for real. I then thought using bought drums was cheating, so I learned to make my own. I then thought using premade skins was cheating, so I killed a goat and skinned it. I then thought that that was cheating too, so I grew my own goat from a baby goat. I also think that is cheating, but I’m not sure where to go from here. I haven’t made any music lately, what with the goat farming and all.”
As neuroscientists continue to conduct brain stimulation experiments, publish results in journals and hold conferences, the D.I.Y. practitioners have remained quiet downstream listeners, blogging about scientists’ experiments, posting unrestricted versions of journal articles and linking to videos of conference talks. Some practitioners create their own manuals and guides based on published papers. The growth of D.I.Y. brain stimulation stems in part from a larger frustration with the exclusionary institutions of modern medicine, such as the exorbitant price of pharmaceuticals and the glacial pace at which new therapies trickle down to patients. For people without an institutional affiliation, even reading a journal article can be prohibitively expensive. The open letter this month is about safety. But it is also a recognition that these D.I.Y. practitioners are here to stay, at least for the time being. While the letter does not condone, neither does it condemn. It sticks to the facts and eschews paternalistic tones in favor of measured ones. The letter is the first instance I’m aware of in which scientists have directly addressed these D.I.Y. users. Though not quite an olive branch, it is a commendable step forward, one that demonstrates an awareness of a community of scientifically involved citizens.

Bruno Sanguinetti and pals at the University of Geneva in Switzerland have worked out how to generate random numbers on an ordinary smartphone using genuine quantum processes. And they say their new technique can produce random numbers at the rate of 1 megabit per second, more than enough for most security applications.
In ‘Maker to Market’ spaces, things can get even messier. Several of the companies on this path depend on ‘open innovation’ models that allow them to engage with keen communities, providing ongoing feedback and mass customisation. This also allows customers to be used as a cheap form of R&D; a practice common in the creative and culture industries, described by Miya Tokumitsu as ‘Do what you love’ where a volunteer workforce works for passion and social capital rather than actual hard cash.
In contrast to academia or industry where knowledge and the market are the main driving forces, DIY biologists’ motivations are broad – entrepreneurs are looking for low-cost and open technologies, artists for new sources of inspiration and materials, scientists for a laid-back creative environment and enthusiasts simply for accessible instrumentation and expertise to satisfy their curiosity. The latter are given an opportunity that few traditional institutions provide, making biological research accessible to the lay public. Even though the mission of DIYbio communities is hard to define without a case-by-case analysis, their potential to benefit society should not be in doubt.
In Yugoslavia in the 1980s, computers were a rare luxury. A ZX Spectrum or Commodore 64 could easily cost a month’s salary, and that’s if you could even get through the tough importation laws. Then in 1983, while on holiday in Risan, Voja Antonić dreamt up plans for a new computer, a people’s machine that could be built at home for a fraction of the cost of foreign imports. The Galaksija was born, and with it a computer revolution.
In this article, I’ll demonstrate a method for modifying a naval telecommunications dish to track moving targets in the sky, such as those in Low Earth Orbit. My dish happily sits in Tennessee, while I direct it using my laptop or cellphone here in Europe. It can also run unattended, tracking moving targets and looking for downlink channels.
Caffenol Recipes that are proven to work can be found here. If not stated differently, the temperature of the solution should be 20 degrees Celsius or 68 degrees Fahrenheit. For all other temperatures, please adjust the developing time accordingly. If you have never used caffenol before, I suggest that you start with films that are proven to deliver decent results, for example the 400 ISO films Ilford HP5 Plus, or Kodak TMAX 400. Slow films that work are Ilford FP4 (ISO 125) and Ilford PanF (ISO 50). Developing times and links to example pictures can be found in the Film Development Chart.
The Journal of Peer Production seeks high-quality contributions from researchers and practitioners of peer production. We understand peer production as a mode of commons-based and oriented production in which participation is voluntary and predicated on the self-selection of tasks.
