“I already own the Unicorn HAT. This one is less bright, but offers more options for pixel art. I'm having lot's of fun with it! I also like the diffuser, it looks so elegant on my Pi. Like others said, the individual colors of the pixels are notably a bit away of each other, but for me this isn't a bother. I also agree that it's a tight fit. Overall a great product.”
“The Unicorn HAT HD is as bright as I expected. So nothing to complain about there. What I'm concerned about is that once it's put on the GPIO pins, its very hard to remove again. I'm afraid it might break if i pull it off. I'd like it to be modelled after the Sense HAT by Raspberry Pi foundation. Or better still: with holes instead of the black thingy (sorry, don't know what it's called) for securing it to the Pi. Apart from that, i couldn't be more happy with my first purchase from you guys.”
“I am amazed by the beautiful light performances this display can produce.
I've started a serious open source project to control this device with a web interface. It's great for showing off animations to others. https://github.com/njbbaer/unicorn-remote”
“This is a lovely upgrade to the original Unicorn HAT 144p-edition, and really makes designing graphics for it a lot nicer. Pixel art really comes to life on the display and looks great, especially when diffused with the kindly included diffuser.
The software is also super easy, as per usual!”
“A very easy product to program with. Nice having HSV support directly.
However...
* The brightness option in the API is incorrect - it says the max brightness is 1.0, but setting it to 4.0 makes it noticeably brighter
* The header block is a very tight fit onto the pins. I've lots of different hats and I think these would have be the hardest ones to install. The blinkt! also suffers from this.
* The subpixels within each pixel are noticeably different places. If you have a row of pixels with different colours you'll notice them not being aligned. The diffuser doesn't fix this.”
“I'm using it to display weather conditions and air quality. API for controlling leds is very simple but functional. There are few interesting examples which can be easily extended to provide more complex solutions. One thing I'm missing is the ability to get data from the buffer to identify what is currently displayed.
I use this hat for weather station and in general it does the job pretty well: https://youtu.be/u-e2rMbgelA”
