Digital Guitar Signal Processor (Embedded Systems Final Project) DIY

This is the final project presentation video for our digital signal processor, which we created as a final project for our Embedded Systems course at the University of Iowa College of Engineering. As stated in the video, our circuit is built around an ATMega88PA. We use an external ADC and DAC to handle the audio signal. The guitar used to demo the effects is a heavily-modded “Fullerton” brand guitar with a Dimarzio Super Distortion from the late 1980s in the bridge position wired with a coil tap and volume control only. The “half-stack” amplifier shown in the guitar demos is a Crate “Flexwave” SS amp set to its “clean” channel with a flat EQ and no effects. Theoretically, this means it did not color the sound significantly. It was used merely to amplify the signal coming out of our circuit’s power amp. Images used in the video are credited within. If you own either of the images we used (“Roadrunner and Coyote” or the “Pedal Board”), and you do not wish for them to be used in this video, please let us know and we will remove them immediately. Thank you, and enjoy the video.

Yaesu ATAS 120A Antenna Maintenance – What’s inside

My ATAS-120A was acting quirky and locking up so I disassembled it for inspection. BE VERY CAUTIOUS if you attempt to do the same. The ATAS antenna needs a very good RF ground to function properly. Most problems that people encounter with them are ground related. Another issue is that the center pin of the PL-259 style base connector it uses is slightly smaller than other center pins resulting in a loose electrical contact with the antenna mount. One way to correct this is to bend the prongs of the mating connector inward slightly so that a good contact is maintained. Thank you KB5WIA for posting a very good guide on this antenna!
