Welcome to my little corner of Open Circuits.

I think I first stumbled across Open Circuits on 2006-03-01. I had been starting to set up a electronics-related wiki, but since this one was already here, why bother?

Feel free to leave a note on my talk page.

I created the WikiNode.

Electronic projects: (Should I move these to dedicated pages such as electronics workbench, etc.?)

Notes for David from russ_hensel

Getting tired of reverting, seems to be getting a lot worse, think you should consider severe steps, approved registration with a short essay prior to joining. Is this too hard. CUI has been spammed and reverted over and over, but it seems to be spreading.

Also how can we best exchange files, can we allow zip files? This would be nice for eagle and other files. Perhaps limit to people who have already done useful edits on the site.

You are currently the admin? yes?

Is there a better way of reaching you? I am at struve13 at the verizon dot net site.


A better way -- edits to my talk page ( User talk:DavidCary ) get noticed much sooner than edits on my user page ( User:DavidCary ).

 phone recieved and deleted 

But I prefer public communication so I avoid the problems associated with (the perception of) back room decisions.

I agree that spamming is getting worse, and Someone Should Do Something.

As you can see from the history of this site at Help:Contents, the User:Chazegh originally set up this site.

electronics workbench

What exactly do I need for "normal" electronics development? I have a pile of stuff, and I have a wishlist of more stuff ... I hope to document which things are important to have, which things are useful but not immediately necessary, and which things ended up just gathering dust.

I wish there were a place like TechShop somewhere local.

  • filing cabinet for all the miscellaneous bits of paper. If at all possible, I attach instruction manuals to the actual tool -- but if that is awkward, I stick the instruction manual in this filing cabinet.

data collection network

I'm building a "data collection network" that may end up with hundred of microcontroller sensor nodes, piping data into a PC. This may turn into a serious medical diagnosis tool.

POV display

(moved to POV display)

Full-color LED lighting

I'm planning to build a silly little toy with 3 LEDs -- one for red, green, and blue -- to show how "additive colors" work (a "color wheel"). (I might just extend it to have a whole spectrum of visible and infrared LEDs, and a prism to show the little spikes in the spectrum that LEDs generate).

"Red, Green, and Blue LED based white light generation" by Muthu, Schuurmans, and Pashley (2002)

LED illumination applications

"How Many Red, Green, and Blue LEDs to make White" by Don Klipstein 2001

LED Color Shifting


I maintain the unofficial PC Card FAQ.

I'd like to move it to a wiki. What would be the best wiki to put it on? Open Circuits?

Open Circuits Sysop

Whee! I'm a sysop at Open Circuits! The power -- it's rushing to my head! --DavidCary 15:20, 23 February 2007 (PST)

Hi David, will be nice to have antispam measures :).

Hi David can you give me some block IP rights ?

Hi David, I noticed that a bunch of open circuits is just a placeholder. I'm effectively retired so I can probably help contribute to this Wiki by expanding a bunch of the sections, but the spam here is really way out of control. I look at the revision history and I see a good 10+ spam edits per day. Don't you think it's time to try requiring a logon to make edits? I thank that would really reduce the spam. Asking people to use a human controlled e-mail address is not that much. It's not like people need to give their real name and address or anything. I think you will find that more people will be willing to contribute if the spam problem is handled. Eliminating the spam is more of a problem at this point then getting people to contribute. It would also free up your time to focus more on real editing. Mzoran 19:38, 12 December 2007 (PST)
