Annie Isobel Hall is a jumper (US: sweater) maker and illustrator, creating hand made knitwear using a Brother KH950i knitting machine in London, UK.

My garments are mostly one offs and everything is sold through commissions. Commissions are taken on a first-come-first-served basis until my waiting list is full. I reopen commissions around once every three months, please check my instagram bio for the next date.

The latest one celebrates computers with a “Hello World” theme.

The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit Radio FeatherWing – RFM69HCW 433MHz – RadioFruit!

Add short-hop wireless to your Feather with these RadioFruit Featherwings. These add-ons for any Feather board will let you integrate packetized radio (with the RFM69 radio) or LoRa radio (with the RFM9x’s). These radios are good options for kilometer-range radio, and paired with one of our WiFi, cellular or Bluetooth Feathers, will let you bridge from 433/900 MHz to the Internet or your mobile device.

These radio modules come in four variants (two modulation types and two frequencies) The RFM69’s are easiest to work with, and are well known and understood. The LoRa radios are exciting, longer-range and more powerful but also more expensive.

• RFM69 @ 433 MHz – basic packetized FSK/GFSK/MSK/GMSK/OOK radio at 433 MHz for use in Europe ITU 1 license-free ISM, or for amateur use with restrictions (check your local  amateur regulations!)
• RFM69 @ 900 MHz – basic packetized FSK/GFSK/MSK/GMSK/OOK radio at 868 or 915 MHz for use in Americas ITU 2 license-free ISM, or for amateur use with restrictions (check your amateur regulations!)
• RFM98 @ 433 MHz – LoRa capable radio at 433 MHz for use in Europe ITU 1 license-free ISM, or for amateur use with restrictions (check your local amateur regulations!)
• RFM95 @ 900 MHz – LoRa capable radio at 868 or 915 MHz for use in Americas ITU 2 license-free ISM, or for amateur use with restrictions (check your local amateur regulations!)

This is the RFM69 @ 433 MHz version These are +20dBm FSK packet radios that have a lot of nice extras in them such as encryption and auto-retransmit. They can go at least 500 meters line of sight using simple wire antennas, probably up to 5Km with directional antennas and settings tweakings

• SX1231 based module with SPI interface
• Packet radio with ready-to-go Arduino libraries
• Uses the license-free ISM bands
• +13 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)
• 50mA (+13 dBm) to 150mA (+20dBm) current draw for transmissions
• Range of approx. 350 meters, depending on obstructions, frequency, antenna and power output
• Create multipoint networks with individual node addresses
• Encrypted packet engine with AES-128

Currently tested to work with the Feather ESP8266, Teensy 3 Feather, WICED Feather, Feather 32u4 and Feather M0 series, some wiring is required to configure the FeatherWing for the chipset you plan to use.

The Radio FeatherWing Guide provides details and use examples.

Discord is a great place to hang with people you like who like the things you like. We like it. Here are Adafruit, there’s a great Discord community where we explore Adafruit projects, plans, and customer projects, as well as hang out during our live shows! Here’s how to run Dicord on your Raspberry Pi, from PiMyLifeUp:

While Discord does not offer an official client for Linux ARM systems, plenty of third-party solutions exist. These solutions are pretty simple as most of them just load the web browser version of Discord but make it act and feel like the native application.

In particular, this guide will be showing you how to install and use a third-party Discord client called ArmCord on your Raspberry Pi. ArmCord is a lightweight Discord client that uses a newer version of Electron.

NASA’s podcast “Universo curioso de la NASA” shares incredible stories from NASA’s Hispanic and Latino workforce with Spanish-speaking audiences from around the world. Its second season is being released this month in celebration of Hispanic Heritage Month, Via NASA

Lee este comunicado de prensa en español aquí.

In celebration of Hispanic Heritage Month, NASA is releasing new content for Universo curioso de la NASA, the agency’s first Spanish-language podcast, now in its second season. A five-week season starts Tuesday with new episodes released weekly.

Listen to the preview of the second season of Universo curioso de la NASA.

In each episode, Universo curioso highlights the contributions of NASA’s Hispanic and Latino workforce to the agency’s work in Earth and space exploration for the benefit of all.

“Through the Universo curioso de la NASA podcast, we are thrilled to tell the story of NASA’s efforts to open space to more people from across the world,” said Tonya McNair, deputy associate administrator for NASA’s Space Operations Mission Directorate in Washington. “In the second season, you’ll hear from NASA’s Hispanic and Latino workforce, like flight director Diana Trujillo and astronaut Marcos Berríos, helping lead some of the agency’s most vital space exploration missions and inspiring the world through discovery.”

Episodes focus on some of NASA’s top missions, bringing the wonder of exploration, space technology, and scientific discoveries to Spanish-speaking audiences around the world.

The de minimis exemption is a special rule for small packages. When companies (mostly in China) ship small, low-cost packages to the U.S. and if the package is worth less than $800, it gets in faster and doesn’t need to pay extra fees, or much/any customs documentation. This rule was made in 1930 to make trading easier, but a lot has changed since then!

The current Administration announced that they’re going to try to stop the misuse of the de minimis exemption. The administration plans to issue new rules for data collection for these shipments, exclude goods subject to U.S. trade tariffs, and require electronic certificates of compliance for consumer products. And, the administration is calling on Congress to pass further reforms to modernize rules like the de minimis exemption. I think this has been announced a few times, and it’s an election year, so unclear to me if anything is really going to happen.

From CNBC –

“…”report – Shein and Temu and determined the two companies are “likely responsible for more than 30 percent of all packages shipped to the United States daily under the de minimis provision, and likely nearly half of all de minimis shipments to the U.S. from China.”

Here an easy DIY for building a Fiber Lamp using WLED. Based on an original idea of andrei.erdei, but completely redesigned (bigger with 36 leds, improved, simpler with WLED)

This fiber lamp is controlled exclusively in WIFI via the WLED interface (power on/off, choice of effects, etc.)

This visor is very light, prints in one piece, and snap-fits to the arms of the glasses.

Worn on the glasses protects your lenses from the direct sun rays, giving you clear vision of whatever is happening on the beach (or you can wear a hat, of course, if it shades your glasses)
