New Guide: PICO-8 Fruit Jam Reality Console

PICO-8 is a delightful “fantasy console” by Lexaloffle that simulates an imaginary retro system that never existed. It is intentionally constrained to 128×128 pixels with 16 colors, 4-channel chiptune audio, 8KB RAM, 32KB storage per ‘cartridge’, and a Lua-based programming language.

You can run wili8jam on Fruit Jam for a lovely, tiny computing/gaming experience. This port, by freewili, puts PICO-8 cartridge running, code editing, and a REPL right on your Fruit Jam, just add monitor, keyboard, and gamepad.

Many of us have been there: working with Claude, ChatGPT, Copilot, etc. and BOOM, the token allowance runs out and you have to wait a few hours for it to reset. All you want to do is finish your project.

Well, you are on your personal computer which can compute things. Perhaps your machine can even play some fairly recent games? If so, you have free compute right at your fingertips.

– This guide walks readers through running a local LLM on a personal computer, covering how to assess your hardware, pick compatible models (using canirun.ai), install a model interface like LM Studio, and tune settings (context length, GPU offload, CPU threads) for best performance.
– It also explains choosing models by capability and license, how to download and run models in LM Studio, and how to add tool plugins (e.g., Beledarian tools) to enable the model to interact with local files and the web.

Today we look at Chinese American Physicist Chien-Shiung Wu

The Wu experiment surprised the physics community by showing that parity was not conserved at the nuclear level; symmetry was not maintained and nature did distinguish between left and right. Chien-Shiung Wu also worked on the Manhattan Project and helped develop foundational methods for separating uranium isotopes.

She acquired many praising monikers through her career “First Lady of Physics,” Queen of Nuclear Research,” and in the recent children’s book “Queen of Physics”

Queen of Physics: How Wu Chien Shiung Helped Unlock the Secrets of the Atom Written by Teresa Robeson, Illustrated by Rebecca Huang

When Wu Chien Shiung was born in China 100 years ago, most girls did not attend school; no one considered them as smart as boys. But her parents felt differently. Giving her a name meaning “Courageous Hero,” they encouraged her love of learning and science. This engaging biography follows Wu Chien Shiung as she battles sexism and racism to become what

In 1752, Benjamin Franklin conducted his famous kite experiment, as depicted in this c. 1816 painting by Benjamin West. This experiment established the connection between lightning and electricity. Public Domain. via Quanta Magazine

Quanta Magazine explores the causes of lightning and why they’re so mysterious to begin with.

Thunderstorms have captivated humanity for millennia, and yet their inner workings remain deeply mysterious. Storm clouds are opaque. They’re dangerous to approach. And they’re too big to fit in a lab. Inquisitive researchers have been sending kites, balloons, and rockets up into them for nearly three centuries, and they’ve learned a lot. But every time lightning lovers get closer to the action, they discover major gaps in their understanding. For the past 50 years, researchers have focused on one particular gap: How does the jagged channel of white-hot air we call a lightning bolt get started?

Gareth Halfacree on Hackster.io found this artistic flight tracker. It’s remeaniscent of an old-school screen saver but tracks realtime flight info. It uses a Raspberry Pi with a 64×64 RGB LED and a MatrixPortal S3.

System administrator Joseph Little has designed a desk accessory that visualizes live air traffic via ADS-B capture and decoding — but instead of the usual radar-like display, shows it on an LED matrix as colorful paths of light.

The Whiskey Tango Hotel blog writes:

The Austin N5OAK Ham Radio Club Repeater seems to be pretty active.  That shouldn’t surprise us much because the club has a lot of activities and a lot of enthusiastic members.  Still, we wondered just how active and opened the spare parts drawer to see if it held a solution.

Turns out the spare parts drawer did; take a look at the wiring diagram at the top of the page.   We simply used an Espressif ESP32-C3 Dev Board with an input pin wired to to the output speaker of a Baofeng HT tuned to the repeater frequency.  We monitor the C3 input pin and if it sees a signal the repeater in transmitting.  We push that data to Adafruit IO at the top of each hour to graph the history.

The post lays out the details and has Arduino code. See it here.
