Hi, I'm Dick Lyon. I am a research scientist/engineer in Silicon Valley, California. I've been contributing to Wikipedia since May, 2005.

Some of my work outside Wikipedia is linked on my ancient techie home page dicklyon.com. More recent research pubs are found here. And don't forget my always-popular Otis King pages, from 1997 (the contact phone numbers there are hopelessly out of date, but I've lost the formula for how to update the site; some of the comments about being on a modem line are also a bit quaint).

And now I'm an author; so buy my book (or see my book blog to access a free online copy) if you're interested in Human and Machine Hearing.

My contributions are mostly related to photography, photometry, color, electronics, and signal processing. And in recent years, mostly photos and style gnoming. And creeks.

Thanks edit

I just noticed that I've received about twice as many WP:THANKs as I've given, so I'm going to try to be more appreciative going forward, and give more. Dicklyon (talk) 16:03, 31 October 2021 (UTC)

I'm particularly grateful whenever someone reverts a mistake I made, so I always thank those! Dicklyon (talk) 23:30, 9 July 2022 (UTC)

I've reduced the discrepancy to more like 4:3 in the last year. That feels better. Dicklyon (talk) 09:20, 26 March 2023 (UTC)

Pictures added edit

Here I collect most of the pictures I've uploaded, mostly my own, but including some public domain images and photos licensed by a few friends.

I uploaded over 100 photos in 2017, and well over 100 in 2018, about 300 in 2019, and somewhat fewer in 2020 and 2021 with reduced travel. Hundreds more from several big trips in 2022 and 2023. Now a few from 2024 (including a few 2024 uploads of older shots).
