Chris Greening has looked at speeding up JPEG image decoding on ESP32 processors.

This is pretty interesting – SIMD (Single Instruction Multiple Data) can potentially really speed up decoding of JPEG files.

Normally when executing code you run an instruction that operates on a single piece of data, then you run the next instruction, and the next instruction etc.. we have Multiple Instructions operating on Multiple Data elements.

With SIMD instructions we have one Single Instruction that can then operate on Multiple Data elements.

This can give a significant performance boost.

Extreme power naps: These penguin parents sleep for four seconds 10,000 times a day. Antarctica's chinstrap penguins could get the same benefit of longer periods of snoozing by taking microsleeps during nesting season, according to a new study documenting one of the most extreme examples of incremental sleep in the animal world.

 

Check out John Park’s new guide on building custom, animated lighting for your LEGO models.

Light up your LEGO buildings, spacecraft, vehicles, and more with super-tiny LEDs. Sets such as the Winter Village and Star Wars lines are just begging to have lights added. You can add lights exactly where you want using pre-wired SMD LEDs. Then, you can animate them to blink, dim, and flicker exactly as you like using CircuitPython.

Or, you can keep it very simple using an on/off coin cell battery holder breakout.
