I’m writing this beginning paragraph last. Is this a wish-list for the engineers who have everything, or just for myself. Nevertheless, maybe you didn’t get what you wanted – or needed this year. Maybe you didn’t get that special person what they wanted. Now is the time to spurge. Ring out 2020 with some last-minute ideas specially tailored to the engineers in your life, whether professional or student.   Additions to their workbench Small purchases can make a bi ...
Fiber-optic cables connect state-of-the-art devices to demonstrate high-fidelity quantum teleportation. (Image Credit: Fermilab)   In a collaborative effort, scientists from technology companies claim to have achieved sustained, long-distance quantum teleportation for the first time. This is a breakthrough that could pave the way toward quantum internet becoming a reality. Their findings are published in PRX Quantum.   “We’re thrilled by these results,” said Panagi ...
Whether you're celebrating having time to yourself, or with family, unwrapping presents or enjoying a tall receptacle of your beverage of choice, from us at the element14 Community, here's hoping you all have a very happy holiday and a great new year!   It's been a very odd year this year, last year I came down very ill, so I was mostly working from home, and this year I've been ... mostly working from home because everyone else's getting ill! What a weird turn of events.   Here's to ...
This is a continuation of my previous post Seeeduino XIAO Expansion board .  I'm going to use the RTC and microSD card to datalog time stamped temperature and humidity data from the DHT11 sensor to a file.   I'm going to use the RTC (PCF8563) and OLED (Adafruit_SSD1306) libraries from my previous post and add the standard Arduino SD library for the microSD card interface.  The SD library will pick up the default SD SPI (MOSI,MISO,CLK) pins from the Xiao variant.h file so we only ...
The capsule collected an asteroid sample the size of dust and pebbles. It also contained fine, black grain outside the chambers. (Image Credit: JAXA)   JAXA revealed that the recently-returned Hayabusa2 spacecraft successfully collected about 5.4 grams of material from the asteroid Ryugu, exceeding its 0.1-gram target. In addition to the soil, the space agency discovered a gas sample inside the collector that “differed from the atmospheric composition of the Earth.” The soil sa ...
Be sure to go vote on the best caption for my Comic Strip Caption Contest #1 in this link. The options are in! Also check out the poll for Comic Strip Caption Contest #2. Vote now!   Also.. Happy December everyone! This is ALSO my Holiday Card for you all too. Thanks for reading, viewing, and participating all year!     When I sat down to make a holiday card this year, I was looking at a pile of dev boards on my work table. They’re an echo of my life, I thought. And du ...
I posted earlier about a couple of SAMD21 mini modules that I'm using SAMD21 Mini Modules .   Last month Seeed Studio released an Expansion board for their XIAO module  https://www.seeedstudio.com/Seeeduino-XIAO-Expansion-board-p-4746.html  .   I've been using their Grove shield for the XIAO and it's handy for prototyping sensor programs and it also has battery management for portability https://www.seeedstudio.com/Grove-Shield-for-Seeeduino-XIAO-p-4621.html  .   ...

M5StickC Modules

Posted by ralphjy Top Member Dec 19, 2020
I've previously posted about small SAMD21 modules that I've found useful for small standalone projects - SAMD21 Mini Modules .   I also frequently have the need for small modules that have WiFi or Bluetooth connectivity.  I've tended to use ESP8266 boards for this purpose because they are reasonably inexpensive and easy to use.  I became interested in the M5Stick modules made by M5Stack after I saw one used by kk99 in the Photonics competition back in March - Simple light flicker ...
China launched the world’s first quantum-communication satellite on August 15, 2016, from Jiuquan Satellite Launch Center. (Image Credit: Xinhua/Jin Liwang)   Chinese researchers have created a new and improved protocol for quantum communication. This allows them to send a quantum-encrypted message from a low-orbit satellite to ground-based stations over larger distances than other communication methods. The improvement could revolutionize how we encrypt and share sensitive data, kee ...
China’s Chang’e-5 mission lands on the moon The Chang’e-5 mission landed on the moon to collect samples of lunar soil and rocks. (Image Credit: CCTV) On December 2nd, 2020, China’s Chang’e-5 mission successfully collected moon rocks and dust from the lunar surface. The probe packed and sealed the samples after a 19-hour operation following its landing on the previous night. Powered by a solar battery, it only had two days to collect and drill for underground sa ...
These nanobarcodes could be used in a variety of sensing applications in the future. (Image Credit: University of Technology Sydney)   Barcodes are used to label and identify everyday items, but what if they could be shrunk a million times from millimeter to nanometer scale? Doing so allows them to be used in living cells to label, identify, and monitor life's building blocks. It could also be mixed into inks to prevent counterfeits. Researchers at the University of Technology Sydney (UTS ...
The image shows the crystal disk containing erbium atoms in the middle. Meanwhile, the red disks represent the light reflecting back and forth (Image Credit: Christoph Hohmann (MCQST)) The first quantum revolution introduced semiconductor electronics, the laser, and the internet. Now, the second quantum revolution expects to bring spy-proof communication, very precise quantum sensors, and quantum computers for previously unsolvable computing tasks.   Physicists at the Max-Planck-Inst ...
