Retro addons: Big box o’ SCSI part 3
I had given up on the SyQuest drive and sold it via eBay with a full description of the problem with it and suggestions on how to fix it. I decided to replace it with a cool tech that would work with my hardware. After chatting to Fletch from some of the retro Discord communities I decided to to get a MO drive. MO stands for Magneto-Optical and it is a sort-of half-way house between a removable magnetic media and a CD. It uses a laser to read and write, but during write the laser is just used to heat and a magnetic write head changes the pattern on the disc.

22 Best Operating Systems You Can Run on Raspberry Pi in 2023
Today, we bring you a list of the best Linux distributions you can run on the Raspberry Pi perfectly. But before we delve into that list, let me brief you on Raspberry Pi Imager.
Raspberry Pi Imager is an official software tool provided by the Raspberry Pi Foundation, which is designed to simplify the process of installing operating systems (OS) onto Raspberry Pi microcomputers. The Raspberry Pi Imager is available for Windows, macOS, and Linux operating systems.

New functionality: Bluetooth for Pico W
In June last year, we launched Raspberry Pi Pico W, a $6 wireless-enabled variant of our Pico platform, built around our RP2040 microcontroller. In the year since, we’ve sold over half a million of these tiny boards, and they’ve found their way into countless projects, from singing fish to web servers to communicative house plants.
But one thing has been missing: Bluetooth support. Now that’s been fixed – and you don’t even need to buy a new Pico W.

Launch your model rockets over LoRaWAN with this MKR WAN 1310-powered system
Milos Rasic of element14 Presents, in contrast, had the idea to create a remotely-operated launching system that would allow the user to simply flick a switch and press a button to achieve lift-off without the need for kilometers of wire. His ignition circuit relied on an Arduino MKR WAN 1310 to receive commands over LoRaWAN™ and the board, in turn, would begin charging a pair of supercapacitors via a series of MOSFETs, relays, and op-amps until they each reached about 8V. Once everything had been tested on a breadboard, Rasic soldered his components onto perfboard and arranged them inside a custom weatherproof case.

Recreating the famous Miller-Urey experiment with Arduino
The conditions that, theoretically, resulted in the first amino acids were an atmosphere of compounds like methane, water, ammonia, and hydrogen along with electricity in the form of lightning. Stanley Miller, under the supervision of Harold Urey, recreated those conditions in the lab with a closed system that heated the gases, passed them through a chamber with electrodes to produce sparks, then down through a cooler and back to the start. That produced many amino acids that could (again, in theory) come together to form genetic code. M. Bindhammer’s reproduction of this experiment works in a similar way, but with a plasma arc instead of sparks.

Updated OSHW Flash Drive Keeps Data Safe, Fingers Dry
For almost a year now, we’ve been following the progress [Walker] has been making with Ovrdrive — a completely open source USB flash drive that features the ability to destroy itself should it fall into the wrong hands. It’s an interesting enough project on those merits alone, but what really made this idea stand out was that the user was expected to lick their fingers before handling the drive as a form of covert authentication.
