The AVR DA Curiosity Nano Evaluation Kit demonstrates Microchip’s new
range of AVR128DA microcontrollers. These have several very significant
advantages over commonly used AVRs, such as much more flash memory
A 12.48 Inch (1304x984) Three-Color E-Paper Display by Waveshare
Introduction
I m running a solar-powered blog and I wanted to add a low-power display to show the daily solar harvest
1 and maybe some additional information.
So I decided to use an
e-paper display. I wanted a display that would be readable from a distance, so bigger would be better. I therefore chose the Waveshare 12.48 inch e-paper display
an example based on data from the summer, generated with Graphite
This particular display costs $179 excluding taxes and shipping at the time this article was written.
Specifications
Waveshare sells a two-color (black and white) and a three-color version (black, white, red). I bought the three-color version. The three-color version is the (B) model.
I bought a Denford Novamill off e
ay for £600 without electronics and built the controller, basically 3 drivers, a PSU and breakout board for less than £200 buying from eBay. My S7 lathe conversion cost around £150 for 2 drivers, steppers and sundry components. I also got a Dell desktop from a local s/h computer store for about £80 plus a flat panel display. Mach3 at the time was about £100 but I wouldn t recommend it any more, it hasn t been supported for years. LinuxCNC is free but reputedly harder to use. There are other controllers, UCCNC for example that many people recommend.
some useful food for thought and questions I need to properly consider many thanks!
