Tomas OK4BX came prepared with an excellent slideshow presentation of the DDS-driven MEPT that he and his father recently put on the air. W0EA was able to show us the schematic and PCB layout of the amplifier T/R switch that he just sent out for manufacturing. You are also able to switch betweenmultiplecams while in the Hangout, which AK6L used to give us some nice closeups of his projects.

I`ve got a USB microscope which is basically a webcam with a high-power lens, so it would work great for showing off close-ups of things as necessary. We also got a neat treat to a live view of WG0AT`s goats Rooster and Peanut, courtesy of his iPhone connection to the Hangout. The only potential downside that I could see when compared to EchoLink is the free-for-all format versus the way that EchoLink facilitates traditional roundtables. It wasn`t really a problem for our group, but I was at a bit of a loss on how to handle moderation. In the future, I think we`ll start off with a sign-up queue to speak, then end with a free-form chat. There`s also no native list of callsigns to call upon, but using a Hangout plugin (Lower Third), you can add a caption to your video stream with your name and callsign just like a TV chyron. The overall impression was that the hangout went better than expected. We had some really interesting information presented and the turnout was excellent for a first time. I think this definitely is superior to the EchoLink chat. Now that I have an idea of what`s going on, it should run even smoother next time. If you are not already a member, go to our Google+ Community page ( Ham Radio Homebrewing ) and join. The next time there is a Hangout, you`ll get an invitation. We`ve scheduled the next one for two weeks from today due to it being close to Christmas next weekend. I`m not sure if this will continue...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
