Check out this new Learn Guide for emulating the NES on Fruit Jam!

The Nintendo Entertainment System (or Famicom in Japan) still holds a certain mystique, with genre-defining games like Super Mario Bros. and The Legend of Zelda. The console remains a popular target for emulation, which is what we’ll do here on the Fruit Jam paired with an HDMI TV or monitor for display. You’ve got several controller options for single player or two player using a USB gamepad and/or a Nintendo Wii Classic/NES Classic/SNES Classic controller over I2C with a breakout board.

The software for this guide is Frank Hoedemakers’ pico-infonesPlus — which came from Jay Kumogata’s InfoNES, ported to RP2040  by Shuichi Takano (building on Luke Wren’s PicoDVI library), Frank’s work on the SD card and game menu, Gavin Knight for metadata file work, and some controller code from Adafruit. That’s a lot of pieces…but you can use a ready-made .UF2 file to make installation easy.

In this latest version, Frank has ported it to Fruit Jam and included support for:

• DAC headphone output
• Onboard speaker output
• NeoPixel VU meter
• Two player gaming with one USB controller plus a second I2C Nintendo classic controller (Wii-chuck style)
• Screensaver using metadata-based game info and box artwork

YouTuber Alexander Gorovenko built this futuristic watch using some sleek micro 5×7 dot matrix displays. Like an iced out Rolex, this watch is instead covered in displays.

Prototyped on a raspberry Pi Pico, in the build he opted for a STM32U083kCU6 chip. He designed a custom flexible PCB to comfortably wrap around the wrist. Great video and project, especially for his first one!

The main parts I used for the watch are as follows,

• The display, which is the HCMS2901 (A more 3.3V friendly HCMS3901 exists now and is easier to find new). I got my displays on eBay.
• The microcontroller, the stm32u08, offers a real time clock and USB programming.
• A vape battery.
• STC4054 LIPO charger IC.
• Generic 3.3v LDO regulator.
• and several capacitors.

I got most of my parts from Digikey but many places sell most of the parts I bought.
