Now, after filling out the order form, you'll be taken directly to the credit card processor's site and you can pay immediately, instead of needing to wait for an email message with a payment link.

Building a PIC24F phase meter

Adjusting an MSK 007 Leapfrog VCF to its best possible operation involves a tricky process of feeding in a 740Hz sine wave and measuring phase differences between different test points. I also had reason to measure phase differences in my recent experiments on recognizing fake coins. Although my oscilloscope has a mode for measuring phase differences that works well enough, it can be annoying to use, and I thought it'd be a fun project to build a better tool. READ MORE
