Gotta love HN, the LED has been flashing all day

Your site looks to be down right now as well -- getting a DB connection error.

May I suggest going static with the site if you can? Dunno what you're using or maybe if there's some dynamic content but I use Hugo[0] and it's quite convenient.

Thank you I fixed my server now.

awesome thanks! I finally got to read the article :)

Way back when "X10" was a thing, a friend of mine made a webui for his lighting controls, he then published this on IRC.

He realized this was a bad idea when people kept turning his lights on and off for days lol. He'd neglected to put any real security or controls on it heh.

I'm glad to see that same spirit is alive and well on HN.

This is cool. I like that you’re connecting with your users in a real-time physical way.

Years ago I wanted something similar which would alert me that someone was looking, and I wanted to be able to login and see what they were browsing.

I imagined looking from the other side of the glass and everything was backwards. Haha.

Since the site is down, here's a random project idea instead, loosely based on the submission title:

I would be awesome to have a high fidelity, perhaps even ray-traced visual LED simulator showing the light diffusion patterns of some classic LEDs and 7-segment LED displays.

Kinda like the popular CRT emulation shaders...

This is amazing, I absolutely love this idea! Must be so cool to see the light flashing haha

I'd love to see more stuff like this, nice work overall!

Thanks, the LED flashed on and off all day here!

>rather than doing this on the ESP8266 EEPROM – which maxes out at 255!

ESP8266 is quite capable of counting higher than 255...

You are right, ESP8266 doesn't actually have EEPROM - the EEPROM library is just faking it apparently. I just used some code from a previous project of mine - on Arduino Nano - which actually doesn't work on ESP8266. Need to update that part. (it does still increment the counter while it's plugged in, though)

Look into EEPROMAnything, and store the number in a long.

I've used EEPROMAnything on STM32duino and it worked well - I think it would work for ESP8266.

Note to self: Show HN for surviving a Show HN on WordPress

Good idea - is the headline, "Don't use Wordpress"?

My server fell over on it's own, apparently, not due to HN (but it has happened to me before)

Hug of death. Poor little server never had a chance.

Wasn't that - an unrelated issue due to an expired certificate and domain, just my luck it happens when people want to see a post I made, while I am in bed, sleeping

wow! Thats amazing things. Keep up the good work.
