What is it?

InkyDash is an ESP8266 powered, WiFi connected minimalist E-ink calendar that shows current date, time and weather information. It is Arduino programmable with a simple UI design that shows the current date, time (as a daily progress bar between the date and calendar section) and weather information.

Technical Specification

Programming Notes

The firmware is developed with Arduino IDE. You can get the source code on this git repo. For modifying the coordinate use in weather forecast, modify weather.ino file according to the comments on the top of the file.

Why did you make it?

My friend from Germany sent me a InkyCal (another e-ink calendar product) a few years ago and it broke down due to the Raspberry Pi was damaged after long period of use. That is why I am developing a new one for myself with a new e-ink display and driver boards with ESP8266 so it can be used as both battery powered and USB powered.

I also take the chances to simplify the UI and make it more minimalist to fit my new Japandi room design.

What makes it special?

Most of the e-ink calendar project out there use the Raspberry Pi Zero as its brain. However, this design is powered by an ESP8266 with the source code (written in Arduino) released on my git repo. You can easily modify the code by updating the coordinate of where you place it and it will update the weather information using web API (no need to bring your own API key).

The PCB that uses to power the InkyDash also come with a battery charging circuit where you can open up the InkyDash back plane and solder on a 3.7V LiPo into it, making it completely wireless :)

Buyer Notes

• I only make 3 of these displays (and one is made for myself). Once sold out, there are no further production plans ahead.
• Battery is not included. But you can easily get a LiPo and solder it in. There are a lot of space reserved for battery and I guess you can easy fit a 3.7V 3000 - 4000mAh LiPo inside it. Remember to get one with protection circuit!
• Before shipping, I will program the InkyDash for you with your coordinates and timezone (base on your shipping address). If you want another coordinate or timezone be programmed, please use the "Additional Request" feature when placing your order.
• As all units are handcrafted, you can expect some minor imperfection to be found on the calendar. But I will test all the units before shipment and try my best to wrap them with layers of shock absorbing foam. In case of any damage is found that effect the operation of the InkyDash, please let me know so I can send you the required replacement parts. (This did not include accidentally connecting the battery with reverse polarity. So please be careful when you are modifying the InkyDash to battery powered mode!!!)
