ESP Clock Needs More Power

[Victor-Chew] is tired of setting clocks. After all, here we are in the 21st century, why do we have to adjust clocks (something we just did for daylight savings time)? That’s why [Victor] came up with ESPClock.

Based on a $2 Ikea analog clock, [Victor] had a few design goals for the project:

• Automatically set the time from the network
• Automatically adjust for daylight savings time
• Not cost much more than a regular clock
• Run for a year on batteries

The last goal is the only one that remains unmet. Even with a large battery pack, [Victor’s] clock runs out of juice in a week or so. You can see some videos of the clock syncing with network time, below.

It is easy to armchair quarterback, but we think [Victor] should investigate putting the processor in a deep sleep mode for most of the time. That probably means you’d need a button to wake it up for configuration and there might be some other modifications required.

If you want to waste a few more ESP modules, you could try this clock instead.
