A project log for DYPLED

a thin LED display in SIP module format, much better than TIL311s to visualise your computer buses

The development of DYPLED had stalled for several reasons. Some were described here, such as the naked vias. There was work, too. And a big problem: the type of LED.

The naked vias are just a matter of ordering yet another batch of PCB with the right GERBER.

Work is done now (#PixelAvenue will open next week)

The LEDs though are a different story. I needed to decide which type of LED I will commit to, from now on. With or without the integrated Zener ?

The choice does not depend on me though.

The only way to decide was to see what type of LED I could use from now on. So I bought more of these : https://www.aliexpress.com/item/3000pcs-lot-0-2W-SMD-4014-LED-Lamp-Bead13-26lm-White-Warm-white-SMD-LED-2800K/32353970900.html (note: I ordered "warm white", the Zener are in the earlier "cold white" order).

They have been delivered and I just tested them : there is no reverse diode (just like the previous order). This means that the PCB requires no change and I can move forward, with enough stock to ... whatever :-D
