Thanks for noticing the bug! The code snippet is out of the mag loop controller code ( /g/BITX20/files/A%2040%20meter%20magnetic%20loop%20antenna ) . It's only using about 30% of the

Another way to minimize LCD activity is to only display the text "delta". The following function is one I created to display text on an LCD. The display being "broken" into a number of "fields"

After endless hours and more diet coke that should be allowed by law, I got the RTC to display on the LCD along with the antenna port. I have this grandiose idea of when the switch is off (But power

Right now, I'm not sure. If there is enough interest, I'd do a short run of 50 or so. I'm thinking about $20ish a pop The photo is deceptive, the board is about 9" square. Double sided, plated through

John, I designed the board and laid it out using diptrace. I had a few made. They are expensive, because of the size of the board. The photo is deceptive as it's about 9" square. Here is a close up

Yeah, and/or: static char oldrig[21]; since strcpy won't malloc any space for you. I actually intended it to be that way but forgot the [21]. I also changed it all 3 or 4 times before I sent

John: There's a subtle bug in your code that could cause problems. In the for loop, the second expression: ??? for ( i = Buffer_Length; i <= LCD_Width; i++ )????? // Yep! puts a space where

And where do you get it? ? -- John - WA2FZW

In addition to what Jack said about not re-writing something that is already on the display, instead of clearing the display (or just a single line) before writing, I just pad the string to be written

Hello Yep, I looked at the circuit and the Hendricks kit already has pads for the DDS. The key question is what can we leave leave out of the board ? I have not built the board yet. The VFO seems

To cure the flicker, store what you already wrote to the display (eg. rig). If it's the same as it was, don't rewrite it. void printrig(char *rig) { static oldrig; if(!strcmp(rig,oldrig))

Wow...nice looking board. How much is the board? Jack, W8TEE To: [email protected] Sent: Tuesday, October 3, 2017 12:19 PM Subject: Re: [BITX20] A bit OT, blame it on W8TEE Here is the RF end

Here is the RF end of the remote switch.

Two ideas I can think of. One, a disc with a hole in it and a led and optical sensor or a disc with a cam lobe on it to trip a microswitch. The 2nd approach is how the old clunk-clunk rotators (AR-22

What Jack said! Writing code isn't all that hard once you learn the language. The important part is being able to define the problem to be solved and then think through how to solve it in a logical

Well you can just count in software knowing there is not enough resistance to miss steps. Once the 3D printer starts on a part, there is no feedback of position, but the do start at home with micro

Great Fun Project. Watch out, Jack will tell you to use a Case Statement! So are there pictures of how you switch the antennas? The Action end?? Relays and stuff? Mike, WA6ISP

What about a Hall Effect sensor fixed to the fiberglass shaft? That way you wouldn't have to contend with figuring out microsteps, but only shaft revolutions. Jack, W8TEE To: [email protected]
