Hi All,

I remember reading a thread a few weeks ago where someone submitted an image of a breadboard demonstrating some feature.

What caught my attention, was that the designer had included a "daughter" circuit board to the breadboard which looked like its purpose was to provide a regulated 5 volts aligned perfectly to the positive and negative rails of the breadboard circuit.

I remember thinking thats a clever idea, but I didnt bookmark it and now I can't find it.

Does this ring any bells?

Thanks

Mark

 

I don't know if it's the same one but I've used this one on one of my breadboards. Works fine.

Thats it!!!

Thanks, it looks quite simple, it could be my "first" soldering project.

Those are very handy. I have 3 or 4 of them.

While you're ordering from HVW, get yourself one of these as well. Why build that MAX232 circuit over and over, eating up a chunk of your breadboard every time. Just buy one and plug it in when you need it.

Thanks Futz, sounds like a good idea.

I would like to tinker with RS232, but as I said in a previous thread it would be tricky as my laptop doesnt have any serial ports.

Then consider giving your lappy a serial port with one of these as well. Slightly expensive, but coming from HVWtech you can be sure that it has been tested for use in programming. You won't have to try multiple converters until you find one that actually does work.

I own that one and used it for a while for programming/debugging a 68HC912 board. No problems whatsoever. It works great in Linux as well - you just have to remove the braille driver. An odd quirk for sure - what the hell is a braille driver doing being installed by default? And why does it break the USB-serial converter driver? But I digress...

You can also use this-> http://www.sparkfun.com/commerce/pro...roducts_id=718 . They have it with different USB connectors.

And this-> http://www.sparkfun.com/commerce/pro...roducts_id=114 is their breadboard power supply.

 

Hey, that's a handy little board! Sparkfun has so many nice products (I remember when they first started - they had a crappy little site with like one or two products). One day I'm gonna get a fatty order together for them.

The reason I was pushing HVW products is that UTMonkey was already going to be ordering from them anyway (besides the fact that they're a good company with good products).

Theirs doesn't hit both bus rows, so you still have to jumper across. Might be handy in some cases, but mostly I want both bus rows powered identically. In their favor theirs does 3.3V as well as 5V.
