Greetings from across the pond near Albuquerque, New Mexico, USA. Another idea for this LCD1602: attach a laser module to the pico, set it up in a doorway, and count foot traffic. Also, with some reflective tape and a little programming, determine rpm's for a fan or even a hobby propeller, much like what you did with the weather vane. I think most might be surprised at how fast the pico can measure rotational speed. By the way, my intermittent contributions to this channel are always based on all your work, not just any one video. Thank you for working so hard to be such a great prof/instructor/teacher.

Great Video Chris! A real walk down memory lane with the 1602 LCD display. My 1st micro project was with a PICAXE micro,and 1602, around 10 years ago. I ended up using a pin and code compatible OLED for a much better visual with no backlight, but I have used the 1602 with many projects since then. Nice to see how useful they are. Thanks for the modern adaptation of an old reliable (and inexpensive) display.

Besides reading the wind speed we can also read the temperature, the humidity, precipitation and we'll have a full weather station, we can utilize this push button to cycle through all different readings. But since I walk a lot I think I can find a way to count my steps. as always, that was a very nice project Thanks Chris!
@DFX2KX 10 місяців тому
there's a few different ways one could count their steps, the cheap/easy/old-school way would be to use a weight hitting a microswitch and then a similar count program. measure your stride length and get distance too. though modern pedometers (like the one inside my smartwatch) use a 6-axis Gyro/Accelerometer, which is also doable.

Thank you Chris. I am always looking for inspiration for displaying Ham Radio data, Grid Square, Lat/Lon, Time, etc. I had a couple of other LCDs but they dies, and 3.5" screens are such a pain. I also appreciate the Waveshare products, as they have proven easy to use/support, cost effective, and very available. The PicoW and Pico W-BT are beginning to draw my attention for inexpensive, dedicated micro-controllers with no bloat, and easy programmability for Ham Radio. I'd like to see something tying an SDR to a Pico for a self-contained package. I was using PiZeros, but we all know about them...

I enjoy watching your videos. I’m most interested in the SBC reviews. It would be really interesting to see cool projects with these boards, perhaps as a series. It would be really neat to partner with other channels that are way outside your wheelhouse. So like how about using an SBC as a controller board for a vintage motorbike project with a channel that builds bikes? Using an SBC to control a very novel set of lights for the bike to keep it safe and visible on the roadways. You mentioned maybe looking at ESP32. You could make content for months easily just scratching the surface with how these things are used. Especially if you start seeing it through with home automation use cases.
@ExplainingComputers 9 місяців тому
Thanks for this. There are indeed many microcontroller and SBC project video possibilities. But I earn my living running this channel, so what is most critical is what the viewers want to watch. And sadly this kind of content does not pay my bills. Today I posted an Arduino video -- my first! But again, not that popular (so far). But I will always return to such content when I can. :)

considering how little power the Pico uses, you could make a self-contained Weather Station. Temperature, wind speed and direction (few ways to do this, via microturbine or anamometer and weathervane combo), sunlight, and rain guage would all fit pretty easily and I think you could get all of those parts on a single I2C bus with some work as well. Or if you know how button matricies work, you'd be able to make an old school calculator.....

Those little electricity meters the energy companies supply work by sending a radio pulse for every 1wh used. The battery on those lasts for months. The same principle could work with an anemometer. Each time the mill turns it would send a radio pulse instead over wires.
