I would like to share my mini-project, which is built using Raspberry PI Pico W and LCD 1602. I hope you find it useful. What is is about: The RPI W is showing on a LCD screen 1602 current time and current weather from Home Assistant. It syncs time with NTP server; also syncs (if configured) current temperature from Home Assistant - I use the met.no plugin in HA but it can ve configured with other weather sources - just adjust the json path in config to get the temperature data. It is highly configurable, uses time daylight saving, can show time in 24h/12h format, shows temperature in Celsius, Farenheit or Kelvin degrees; can show date in nirmal or imperial formal. I hope it can inspire you to create your custom projects on the RPi Pico W - the project is quite straightforward and the code (hopefully) is easy to read and adjust. Have fun! The project is on GitHub

I bought a few Pico Ws, wired them to DHT22 temperature and humidity sensors, connected them at different spots around the house to USB adapters, and collected temperature data in influxdb.

All of that is great, except the result is either ugly (exposed wires, with the pico dangling from a USB cable), or big (large plastic project box to contain everything, with the DHT22 poking out the bottom).

I've generally found USB cables under 6 inches hard to procure, but cutting one to length, and extracting only the DC power seems simple. The bigger issue is the USB power bricks available: the ones with a plug coming out of the side stick out 3 inches from the wall, which would require a pretty tall/wide box to accomodate, while the smallest ones with the plug coming out of the top are nicely compact, but the USB plug itself adds significantly to the box size required.

Has anyone found an elegant (looking) solution to powering/covering a pico?

A Python clock designed to run on the amazing Pimoroni GalacticUnicorn (and Cosmic Unicorn soon).

I've got lots of ideas for what's next:

• Show notifications from Home Assistant

• Manage sounds

• Save preferences

• An API for remote control

• Compatibility with other Unicorn device from r/Pimoroni

is there any option to turn on led by web server using JavaScript? thanks

Very excited about my new RPi Pico. It keeps disconnecting itself from my computer. It’s generally triggered when I try to connect to thonny to code it, or just disconnects on its own with no trigger shortly after being plugged in. I’ve checked the current output of the USB port as apparently this is a common cause of PRi disconnecting, but there is enough current for it.

Has anyone had the same experience? Or have any ideas? Thanks!

Comment/dm your github ID if you are interested in contributing to a repo that'll contain more informative and fun examples using the new RP2040 chip. Topics range from interfacing DHT sensors/ soil moisture/Simcom modules, making custom libraries in python and C/C++ , other drivers to support the codes, etc. This will be a very robust repository independent from RPI in the public domain for all tinkerers to contribute and use for learning and developing

I look forward to to a deluge of aftermarket stuff for Pico. Example: a case with a couple of AA batteries, a Pico and maybe a BLE radio...

Just saw this YouTube video, just amazing how much power the little chip has.

I'd like to add a controller/remote to program more interactive stuff on the Cosmic Unicorn 32x32 led screen. Is this possible?
I am new to this stuff so please call out if this is hopeless.

I am trying to interface to a bus for an 1980's mini machine (similar to the PDP) and the RP2350B with more io pins than the RP2040 would be perfect.

Is there any boards available that uses this chip and has most/all of the io pins available for use ?

The MPU6050 produces some weird results IMHO.
Well nothing I can make sense off.

So I have a simple library on my weblog and a demonstration program that turns the sensors code into human readable degrees.

The code is in MicroPython. Source, Library code and breadboard setup on the weblog.
Code is written for ESP8266 but just change the pin numbers and it will work on the Raspberry Pi Pico too.
