Linux to Support Firewire Until 2029
Further, Takashi Sakamoto says that his work will help users transition from Firewire to more modern technology standards (like perhaps USB 2.0). Apparently, Firewire still has a dedicated fanbase that is big enough to warrant six more years of support. But we suspect this will be the final stretch for Firewire support, surrounding Linux operating systems. Once 2029 comes around, there's a good chance Firewire will finally be dropped from the Linux kernel altogether.

Doom on a LEGO brick
We’ve seen portable games projects before, but nothing quite this small! Maker James Brown took on the huge challenge of embedding a playable game of the classic first-person shooter Doom in a LEGO brick, powered by Pico’s RP2040 chip and featuring a tiny OLED screen.

New Product Preview: RP2040-PICO30 Raspberry Pico with 30 GPIO available!
For our new Neo6502 design, we needed to use all 30 GPIOs on the RP2040. Although the RP2040 has 30 GPIOs, only 26 of them are available for the user, as GPIO23 controls the power supply, GPIO24 detects if USB is connected, GPIO25 is connected to the status LED, and GPIO29 measures the power supply after the 3.3V voltage regulator. While all these features are nice to have, there are many situations when you need to use ALL available GPIOs.

This board is currently in the prototype stage and will be available for sale in late May. [...]

What Can You Do With Teensy?
So, let's say you've got a few Teensy's lying around or have been interested in working with the Teensy line. Maybe you've been sitting on a Teensy or two, just waiting to be inspired to make your next project. This crazy fast microcontroller equips makers with a wide-range of potential use cases and possibilities - so many that it might even get a bit overwhelming. Good news! We've assembled some creative fodder from around the web for you to chew on while you contemplate what to make next with a Teensy.

The Environmental Sense Mask monitors air quality in real-time
In order to get values for the air quality index (AQI), CO2, volatile organic compounds (VOCs), and temperature/humidity, Karthik selected the Nicla Sense ME due to its onboard Bosch BME688 sensor module. In addition to providing this data over Bluetooth® Low Energy, the Nicla Sense ME also sends it over I2C to a MKR WiFi 1010 which is responsible for parsing the data. Once done, a comment is generated for the current AQI ranging from “excellent” to “hazardous.” This reading is displayed on an attached OLED screen and a ring of 24 NeoPixel LEDs are illuminated according to the level of dangerous pollutants.
