James Lewis writes about the ThunderScope which features to 350 MHz analog bandwidth with 1 G/s sample rate streamed to a PC at 1 Gb/s:
Oscilloscopes can be an electronics engineer’s best friend. These highly versatile tools are helpful, from basic debug to verification tests to compliance checks for standards. Not only are their measurements varied, but so are their form factors. Two common styles are “bench” scopes, which go on a bench, and PC-based oscilloscopes, which, until now, have primarily used USB. An Ontario-based EE graduate student, Aleska Bjelorlic, is launching a Crowd Supply campaign for an open source software-defined oscilloscope. The four-channel ThunderScope has up to 350 megahertz of bandwidth and can stream acquisition data to a PC at one gigasamples per second.
Since we last covered ThunderScope, Bjelorlic and friends have further developed the hardware to a near-final state and have continued extensive work on the software side.
ThunderScope comes in an unassuming box that is just large enough to house 4 BNC connectors, a compensation output, four fully-functional front-end stages, an ADC, and an Artix-7 FPGA to capture the data and transfer it to the PC.
OreSat0 is a fully open source CubeSat satellite system built from scratch by the Portland State Aerospace Society, an interdisciplinary student group at Portland State University. Roughly the size of a tissue box, the tiny satellite includes everything larger satellites have — including solar panels, batteries, a color camera, and an amateur radio system. It’s scheduled to fly onboard our SXRS-6 mission no earlier than January 2022 on SpaceX’s Transporter-3 launch.
Slated to be Oregon’s first satellite, OreSat0 is the first of three satellites being built by the students. It’s mission is to test the modular, expandable, open source, and education-friendly OreSat CubeSat system. With this first flight under their belt, PSAS will build its next, larger satellite for the NASA CubeSat Launch Initiative (CSLI). This second CubeSat has a global climate science and STEM outreach mission: it will help refine global climate models by measuring the global distribution of high altitude cirrus clouds.
Oak Development Technologies has unveiled another board built around Raspberry Pi’s incredibly popular RP2040 microcontroller: the compact, castellated, surface-mountable Cast-Away RP2040.
“Cast your project fears away with the Cast-Away RP2040, a small and easy to use RP2040 dev board designed to take your project to the beach,” writes Oak’s Seth Kerr of his latest board design. “This board uses the popular Raspberry Pi RP2040, a dual-core Arm Cortex-M0+ microcontroller.”
The twin challenges of the pandemic and now the semiconductor shortage have been particularly hard on the designers of event badges, as events have been cancelled and uncertain supply issues render their task impossible. When an event goes virtual, how do you even start to produce a badge for it? Make the badge and rely on enough stalwarts buying one? Or maybe produce a badge that’s a fancy take on a prototyping board?
So if you’d like to chase the full Remoticon experience with a badge there should still be enough time to order a set of boards, but to design your own electronics you’ll need to get a move on. What you might build upon it is up to you, but if you have an ESP32 module lying around you might wish to consider cloning the SHA2017 badge or its successors with the badge.team platform.
Got a Halloween project that you think is prize-worthy? Submit any project published in October 2021 with a spooky theme, and you could win a free Ouija-esque planchette PCB that you can use to program an ESP8266-01 module with Arduino code! Plus, you can attach the bare board to an earring hook, keychain, or lanyard for personal tech flair.
Thanks to our awesome friends at OSH Park, 3 winners will each receive a code to order a three-pack of boards in the “After Dark” colorway (which gives the PCB its seasonal black-and-gold aesthetic). Yep, that means one to keep and two to give away – or two to wear and one to use! It’s up to you.
The AIS-ILIS1 Ionic Liquid Ion Source Electrospray Thruster represents the first generation of micro-ion propulsion development at AIS. The ILIS1 offers unprecedented access to advanced ionic liquid electrospray thruster technology for nanosatellites, bringing this state-of-the-art, high-performance technology to a level that is affordable for any nanosatellite team. The ILIS1 is also the first ever PocketQube-compatible ion thruster to be successfully designed, built, and fired in the field yet.
The ILIS1 takes a new approach towards ionic electrospray by utilizing low-cost CNC manufacturing of the emitters as opposed to conventional micromachining technology. Coupled with high-performance 3D printed parts and readily available components, the ILIS1 achieves unparalleled accessibility and cost reduction. Using highly stable, safe, and well characterized EMI-BF4 fuel, with passive capillary feeding, the ILIS1 elimiates the need for any high pressure fuel feed or complex valving requirements.
Ionic electrospray technology is one of the most promising technologies for low power, higher thrust and ISP performance for nanosatellites. The first round of testing has been completed for the AIS-ILIS1, which has paved the road for the next generation AIS-ILIS2 development.
In the last few years Application-Specific-Integrated-Circuits (ASICs) have become one of the most interesting fields to work in for Physicists, Computer-Scientists, Electrical- and Nano-Engineers. It was only a question of time before toolchains for the design of ASICs were democratized.
This event is for anyone interested in learning and sharing how to design ASICs with open source tools.
We’ve already unveiled multiple keynote speakers and a slate of fascinating presenters that will be showing off everything from reverse engineering vintage calculators to taking those first tentative steps on your CAD journey for this year’s Remoticon. You’d be forgiven for thinking that’s everything you’ll see at the conference, but there’s still plenty to announce before the two-day virtual event kicks off on November 19th. Normally we’d be promising to make sure you get your money’s worth, but since tickets are cmpletely free, we’re shooting a bit higher than that.
