Re: Bedini motor

Did anyone catch MythBusters last night? They had a segment on "Free Energy" including the Bedini Motor. Damn thing started up slowly ,raised in speed, then slowed down to a crawl and finally stopped. BUSTED on national TV!!!<p>CeaSaR

Re: Project for interested 10 yr old

The 2n2222's that I looked at had ratings of 60v and 800ma, that's why I thought of using them. Not sure if they had any suffix or not. Plus, they come in a 15 pack, so if something happens they can be changed without a trip to the store. I'll have to look again to make sure what I read. You know ho...

Re: Project for interested 10 yr old

OK, I started a search and found Len's PSPICE Circuit Attic . His first PDF has a schematic I might just be able to scale for my requirements. Does anyone have any suggestions about what might need to be changed for 9-12 volt operation and using 2n2222's for the outputs? I would appreciate any help....

Re: Project for interested 10 yr old

I believe I found the schematic for the Qkits project here ,only it's a KitsRus.com PDF on www . electronics123 . com! Go figure.<p>Looking over all the info I've come across (thanks to all who have pointed the way!), I have realized that what I am actually looking for is a quasi-complementary topol...

Re: Project for interested 10 yr old

Paul, I like what Qkits has there - I just wish they published the schematic they reference. Circuit: complimentary pair feeding an emitter follower - output at the emitter... Hmmm, an idea is fomenting...<p>Philba, Great link! Got a few pages printed out. I know RS is more expensive than most anywh...

Re: Project for interested 10 yr old

OK, here's the scoop. I looked through my junk "pile" and came up with several Jim-Paks of 2n3904/06's, tons of resistors (mostly 1/4 watt, various values), many electrolytic and ceramic caps (also various values and voltages). Looked in Radicle Slack and found that the single most prevalent transis...

Re: Project for interested 10 yr old

Read a post get a reply! That's what I call service. Yes, that is pretty much what I am looking for. Does anyone have a schematic and parts list I could use? One channel would be enough for me to duplicate out to stereo. I would still like to walk into RS and buy all the components from the boxes. M...

Re: Project for interested 10 yr old

Hey!<p>You 2 got in there before I could post. Peter - my thoughts exactly. Like I stated originally, his buds at school don't get into the guts of things. It's easier to buy new instead of fixing or building. If he can build this amp, his next project would probably be an alarm to keep his little b...

Re: Project for interested 10 yr old

So far,<p>1. Rat Shack doesn't have S*** in the way of real kits anymore. The only time they have anything close to what they used to have back in the late 70's and early to mid 80's is around now. But they are just the snap together/springclip all in one type thing - which I already have, thank you...

Project for interested 10 yr old

With the holiday season here and some time off coming up, I thought I'd let my 10 yr old son build something to get him started in electronics. Though I've been an avid reader of many publications for over 15 years, I still am not at the design end (the thread on CIE reminds me how well real schooli...

Re: A vision

Did someone say science FICTION? OK, good sf is based on fact, but a writer has leeway with the truth. Perhaps this should be Science Fantasy?<p>Dean - loved Silent Running when I saw it premiered on TV. Just rented it last year - even made my non-techie sister-in-law fall in love with the little bo...

Re: Floating point equations to integer equations?

First thing that comes to mind is: 'to raise a number to a power use the carrat sign between the number to be raised and the power'. Ie: 2.45^20is 2.45 raised to the 20th power or 60718591.32 (that's as far as my handheld calc goes). At least that's the way QuickBasic does it.<p>Here's a sample:<p>1...
