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.

The artificial horizon display might be good for someone in an earthquake zone…
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!

U4 was fun. Found the obsure not that says to bend all the pins underneath so the part can be solders. The pads were meant for a different part than is currently shipped with the kit.
The 1206 parts are easy to do. Only 3 Ics are scary, the PIC, U2 and U3. The rest are not fine pitched if you have done any other SMT kits.

This a review of a Yaesu FT-817 Solar Powered Go Pack. I built this solar powered case for my FT-817 radio so it can be used portable without the worry of power and keeping it self contained. It’s all contained in the case so it can easily be taken to a picnic, on holiday or attached to the backpack for a QRP adventure. Total cost for all the bits excluding the radio is about 0-0 (most bought off Amazon). solar powered ham radio

Earth Changes Explained: The cause and what we can expect in the very near future. * Symptoms: Earths Erratic Magnetosphere, Mysterious Magnetic Blasts, Intense Electro-Magnetic Interference, Wobbling Earth, Changing Weather Patterns (Global Warming/Climate Change), Worldwide Drought and Deluge Conditions, Extreme Crop Failures and Food Shortages. Increase in Major Earthquakes and Tectonic Plate Activity, Unstable/Shifting Ground Reaping Havoc on Man’s Infrastructure, the Mayan Calendar, 2012 and Crop Circles.
This location is an anomalous area and believed to have a gravitational or atmospheric disturbance in which its natural properties in the area possess electro-magnetic interference that effects sporadically with humans, machines and electronics and that it still remains to being unexplained. The zone lies just north of the Tropic of Cancer and south of the 30th parallel, which places it in the same parallel planetary anomalies such as the Bermuda Triangle. Considered to be the Mexico’s version of Bermuda Triangle, Zona Del Silencio (Zone of Silence) is four hundred miles away from El Paso, Texas surrounded by deserts. The place of its surrounding and territories have mysteriously enough been blocking and draining radio and TV signals, and have been associated with the UFO phenomenon that may have cause several crashes including the Roswell UFO craft that went through here over lighting. The US military have sent down several technicians and scientist to the region to investigate its surprising odd phenomena that have affected some of their surface to air weapons and aircrafts testings and operations, most note worthy are: missiles (a known incident is an Athena missile fired from the White Sands Missile Base, went off course inexplicably in the vicinity of Zone of Silence, where it crashed) and rockets (an upper stage from one of the Saturn boosters used on the Apollo project broke up over the very same area) and other top secret projects. Just had to follow Coyame Crash …
