Re: Portable PA System

Replace the $35 amp in sofaspud's post with this 10w amp kit for $9.70 (or similar) and you may be set.<p>It's been 10 years since I've built an audio amp, so I don't know if this one is high quality, but my guess is for vocals it will work fine.<p>Remember, if you get a high effeciency driver (like...

Pic circuit with built in programmer

Hello,<p>I'm *imagining* a simple circuit that has a serial port for two way communication with a PC. With the flip of a switch (or pound of a fist) the serial port becomes the interface to a programmer for the pic processor. This would be for a newer Pic, such as the 16f628 of 16f88.<p>Am I barking...

Re: Magazine On Racks where?

I get mine at Barnes & Noble. They often also have a nice "Thomas the Tank Engine" train table, if you happen to have a train fan in your house.

Re: Out of toner in a printer...

I'll never buy anything but an HP again.<p>I avoid the cheap models like the plague, no matter what brand it is. Look for the "business class" models if you want to lower your cost per page and increase the life of the printer.<p>One thing I like about the HPs is that the print head is in the cartri...

Printable breadboard

Hey all...<p>I had a schematic that was being difficult to breadboard, so I created a printable PDF breadboard in Visio. Since others may need it, I've linked it on my website here: Printable Breadboard . (you don't need visio to use it, just Adobe Acrobat Reader )<p>If you can suggest any improveme...

Re: hooking up an alternator, question

A VW beetle my brother and I are working on has a generator instead of an alternator. It puts out voltage that is dependent on RPMs, so the VW has a "regulator" which keeps the voltage in proper range for the electrical system.<p>I don't know if that's any use to you. At 2,000 engine rpms the genera...

Re: CAN ANY ONE TELL ME WHAT TO DO NEXT?

To go to the next step, you'll need a volt meter. You can get a digital multi-meter (DMM) at cheap hardware stores for about $10 USD. Paying up to $25 is reasonable if you don't have an ultra-discount place near you, such as Harbor Freight Tools.<p>You'll likely need a soldering iron before the proj...

Re: electric fence

The lm3909 are very hard to find. Now, you would probably use the very common 555 circuit. The link I posted above has some excellent explanations of the 555 and some example circuits.<p>Someone confirm... what is out these days that works well at 1.5 v?<p>I think the LMC555 is a lower power/voltage...

Re: Disabling MCLR on Pic 16f628a

Thanks, I will be using ICSP. At this point it won't be until next week before I get back to this circuit so I'll probably have some more specific questions then.<p>I'm really pleased with the features and price of this 16f628. I realize the 16f88 has even more, but I really don't need that stuff an...

Disabling MCLR on Pic 16f628a

I've noticed the 16f628a allows you to use MCLR as an i/o. Can anyone point out the pros and cons of doing so?<p>I like the fact that 16f628a is *cheap* and can have up to 16 i/o pins using the internal clock. If I disable MCLR and use the two USART pins for serial communications it will give me jus...
