Don't you mean that we have gone from an age of wooden ships and iron men to composite ships and synthetic persons (must be P.C. here).

at what? pse provide a link to the product - tks Allard 73 PE1NWL

take a look at this. Buy it as a kit or finished product. I bought one. It works very well on most antennas I have used. One of the keys is to have the correct balun or Unun for the antenna. I did

Back when men were men, ships were made of wood, men were made of steel, and electrons were the size of marbles. 73 Kees K5BCQ

You also had CROS cards which you could modify by cutting the lands by hand on a blank CROS card (80 column). Model 30 used them and inflated thin plastic bags to make contact. Made one of those late

Ah, you clearly missed the point. All those editors and compilers and stuff are sissy too. They were hand coding binary bits into those transformers. Got us to the moon! Haven't been back since.

"None of this sissy IDE stuff." What? I think IDE's make life easier. Those who want to use discrete editors, compilers, assemblers, and linkers are welcome to it. I prefer to be a sissy. Jack, W8TEE

There is a trick i use for this. I stack all of the S/H enables on one bus (one processor pin and it can be multiplexed with a whole host of other events). Then you have all of your samples taken at

Yeah thats the one i was thinking of... Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois Owner –

Do not despair, I ordered March 24th and got word from DHL that it will be here Monday May 14 ANG KM4TRT

what is the best way to solder the ISP header pins to the NANO without having to remove it from the Raduino board? I want to back a backup copy of the firmware already on my Raduino bard before I

Thanks, Don. That clarified it. ----- Mark, KE6BB

I don't think that's a win. The only way to tell the S/H to take a sample is to communicate via the i2c bus. I suppose you could have two i2c buses, drive them simultaneously when taking a

Great book! As an engineering intern in 1973, I worked on a fire and security system that included DG Nova serial #4. One of my mentors later moved on to DG at Research Triangle Park to work on the

You could also use 2x MCP3221 parts with an I2C interface and you would have 2x S/H,12 bits and 2x SOT-23 package for even fewer $ 73 Kees K5BCQ.

Had to look that one up: transformer read only storage Now that's how a real programmer writes his code. None of this sissy IDE stuff. In the rope format, it was TROS in the Apollo guidance

My father worked at IBM during the days of core storage. I remember touring the Poughkeepsie plant and watching the cores being strung by hand under strong magnifying lenses and bright lights. You

Actually, JackAl has very little to do with my FDIM presentation, which is on homebrewing. The JackAl board will be shown at the Show-and-Tell, which I think is Friday evening. Jack, W8TEE
