Cool ticker with cool features to come! I like this case design with a epaper display.
When i turn off the device will the last image remain visible ?
Does it run on a battery ? if so how long ?
Hi klaaas, thank you for your interest.
Yes, the last image will be retained until the next boot cycle (in the photos the device is not powered on).
At the moment it only runs out of a micro usb cable, but the pcb inside already has a battery connector and charger.
It is within my plans to add the battery and make it more power efficient.
Some similar devices can run for more than 1 year on a single charge (querying data once a day) and using deep sleep.
So, in the current state, it works (i.e. takes power) only if it is connected with a micro usb cable. When you are saying that it is in your plans to add the battery, what do you mean? You will release a different model that supports a battery, or all the previous sold models, will be compatible with the battery integration?
What do you mean "Some similar devices can run for more than 1 year on a single charge". So, can we charge this device (and hence work without a constant power supply) or not?
Any other color case option, except of white?
Does the device work over Wi-Fi?
Hi klaaas,
Q: When you are saying that it is in your plans to add the battery, what do you mean? You will release a different model that supports a battery, or all the previous sold models, will be compatible with the battery integration?
A: All of the devices are already compatible with a battery, as the electronics already have a battery connector and a charging circuit. At the most the case will have to change in order to fit in the battery.
Q: What do you mean "Some similar devices can run for more than 1 year on a single charge". So, can we charge this device (and hence work without a constant power supply) or not?
A: The current model does not come with a battery. Firmware adjustments will have to be made, as at the moment the goal was not to make the device power friendly.
Q: Any other color case option, except of white?
A: Soon I will have red and black available (quality is the biggest issue when dealing with different colors).
Q: Does the device work over Wi-Fi?
A: Correct, soon I will post a guide on how to perform the initial setup. Basically the device create an access point if no wifi is found named PaperLedger. The user then connects to the access point and browses the web portal at
http://paperledger.local. A prompt will appear to setup the network. Once that's done the device will connect to the wifi and tickers/alarms can be added using the web portal
Hope this answers your questions.
