Re: Source for 796 kHz oscillator coils

If I recall correctly, they are the IMF cans for an AM radio. If I am wrong, I'm sure we'll find out. As for the rest of your question, I'll let the big boys take over.<p>CeaSaR

TraxMaker help

I downloaded the student version of CircuitMaker and wanted to see what a circuit would look like on a board. When I tried to export the PCB Netlist, Circuitmaker couldn't find TraxMaker. Is TraxMaker only available with the PRO version? If it is, what would be a free/inexpensive compatible program?...

Transistor pinout

As I mentioned in an earlier post, it has been a long time since I actually picked up and made anything electronic, so... I am trying to remember what the pinout of 2n3904/06 and 2n2222 are. Holding the transistor upside down (leads up in the air) with the flat toward you, are the leads C B E ? Than...

Re: VHS or hi8 recorder..

While it doesn't have it's own battery compartment, it does run on 12V! http://www.jcwhitney.com/autoparts/ProductDisplay/c-10101/s-10101/p-275645/mediaCode-ZX/appId-634955 <p>If you are looking for anything like this (battery powered) the best places to look are the RV markets. Try one in your loca...

Re: Bedini motor

Stephen,<p>No doubt they all work to some degree, but as you said they are usually impractical as the gains are so small as to not be of any real use. The law of diminishing returns as it were, and they all take some form of energy created elsewhere to start and run to the point of "exhaustion". The...

Re: Bedini motor

They (Jamie and Adam) pulled several "free energy" plans off the net and built all of them one by one. The first one was some bizarre scheme to capture space waves and convert them to energy. The test had 2 motors hooked to singular lithium bateries, one with the space wave gadget (looked like 3 tra...

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...
