Had a thought about making the eyes go dark for a few seconds with sound. Any thoughts on hardware and code?<br />Thanks,<br />RichAnonymoushttps://www.blogger.com/profile/00090758892307805553noreply@blogger.comtag:blogger.com,1999:blog-1634572204034071649.post-20788786774943048782012-10-24T08:32:17.812-04:002012-10-24T08:32:17.812-04:00Hi Anonymous,

You will also see these symbols elsewhere on the schematic such as on pins 10 and 20 on the ATTiny2313. Anywhere you see these symbols, they should be connected together electrically. Often, we draw schematics this way to avoid having excessive lines drawn and we assume they are to be tied together.<br /><br />-PetePetehttps://www.blogger.com/profile/10432659350949374712noreply@blogger.comtag:blogger.com,1999:blog-1634572204034071649.post-55786285938680030272012-10-24T01:39:52.898-04:002012-10-24T01:39:52.898-04:00Very cool!

I took a look at ...Hi Raven's Hollow Cemetary,<br /><br />I took a look at the schematic and must admit I am not sure where the " TV " part of the 7805 designation came from. <br /><br />The 0.33uF and 0.1uF capacitors on the input and output respectively, of the 7805 are pretty standard so I will say yes, you can almost certainly substitute any 7805 5v regulator that you have.<br /><br />From the datasheet, the ATTiny2313, running at 8MHz will operate from 2.7v - 5.5v. If you were to change the operating voltage of the system for some reason, don't forget to recalculate new current limiting resistors for the LED " eyes ".Petehttps://www.blogger.com/profile/10432659350949374712noreply@blogger.comtag:blogger.com,1999:blog-1634572204034071649.post-49939903291929349822012-07-04T00:03:00.334-04:002012-07-04T00:03:00.334-04:00Hi Pete :) Love the design, and I'm in progre...Hi Pete :) Love the design, and I'm in progress of making one of my own for my haunt. I do have one question for you though. I have several LM7805's lying around, but I've never seen a 7805TV as you indicate in the schematic. <br /><br />My question is (since I can't find a data sheet on the "TV" variant): Can any other LM7805 be subbed in place of? If so, which is the closest match in specs? <br /><br />Thanks for the schematic & posting this tutorial. Much appreciated! :DAnonymousnoreply@blogger.com
