I put this in a box this morning. Arduino + AD9850 shield by Paul M0XPD and Kanga UK. Code by AD7C. One stage amplifier by Pete Juliano N6QW. Useful as a VFO or a sig generator. Thanks to all involved.
Note the cool translucent feet!

Where do you put the Tubes?? and Analog parts?? and what are you ordering breakfast??? LOL It looks great Bill...
ReplyDeleteI also used the code by AD7C. When I put a picture of mine on Twitter a while ago I got a comment back saying "The 'h' in Mhz should be uppercase". Factually correct I think but I can't be bothered to open up the box to re-program it.
ReplyDeleteIt's the soul in this particular machine!
I would have responded by changing it MC/S if there is enough room on the line.
ReplyDeleteBill - which buffer output circuit did you choose?
Can you please post the links for the code and buffer amp?
ReplyDeleteThanks

Richard, AD&C's code is available here. There is a version that allows for IF offset:
