So I am wanting to make a Raspberry Pi clock with either a Pi Zero or a full size Pi.

I am thinking of using this OLED screen but don't know if it's big enough to see from a distance.

It will be a digital clock, I was thinking of using OLED because it will be better at night because it's not as bright.

My other option would be the negative version of this.

I think the first option might be a bit on the small size, the screen is only 1.3" diagonal.

This is about full size on my pc screen you can check it by measuring across the yellow arrows.


The 16x2 LCD will be bigger about 2.25" diagonal, you can read the 16x2 LCD from about 4-5ft away.

This is about full size on my pc screen

Or you could use a "Clock LED Display":
Two examples: ... splay.html (Software multiplexed) ... splay.html (basic data) ... PcbHS.html (Hardware multiplexed**, inc. brightness controls)
** + an RGB led

Still running Raspbian Jessie on some older Pi's (an A, B1, B2, B+, P2B, 3xP0, P0W) but Stretch on my P3B+, P3B, B+, A+ and a B2. See:

Thanks for the replies guys.

I decided to use a Scroll pHAT HD as I can then do animations and other stuff as I am planning on making it a smart clock, kinda like a LaMetric time, should have said that in the first post. :)
