While the term is used in many different ways, on this blog I would suggest that hobby broadcasting is about trying new ideas and exploring interesting concepts. Unlike community radio, which is focused on the audience, I feel that true hobby broadcasting is mostly about the broadcaster. Trying new frequency bands, using different content delivery modes and exploring little used technologies .......

My attention is drawn towards the noise behind me. I cannot believe it. There it is. The Arduino is taking a SELFIE !! How did this happen? Well actually, it is not that difficult for an Arduino. I found out that my Canon Powershot SX50 HS camera has a port on the side for a remote switch. In the "Optional Accessories" section of the camera brochure, it identifies th.......

Finally, I was able this weekend to get some time to update the blog, God it feels like an age since I have been able to get a moment of time to sit down and put stuff together. It's been driving me mad, I've spent every day of the past 2 weeks saying to over and over "I have to update the blog, I have to update the blog!!" juggling shoots 4-5 days per week and working every second weekend on my Delicious contributor feature means I nowadays get so little time to myself. I am currently working a.......

This is an electronic stethoscope circuit diagram. The operation of the circuit is very simple. It's work is similar to general home audio system. The heartbeat sounds catched by electret microphone and then the amplifier amplify the signal. Component List:R1 = 10K 1/4WR2 = 2. 2K 1/4WR3, R9 = Not usedR4 = 47K 1/4WR5, R6, R7 = 33K 1/4WR8 56K = 1/4WR10 = 4. 7K 1/4WR11 = 2. 2K to .......

The latest version of the lap timer includes two new features -1) External Audio - There is now an option to use a very simple amplifier circuit which is small enough to fit inside most project boxes. This will give you a lot more volume when you are using the system outdoors. 2) Countdown - With countdown switched on, the lap timer will beep to count down the last few seconds of the current lap time - it adds a little extra pressure - to beat the lap you have to beat the beeps. For previous ste.......

An adventure of the Southern Appalachian Space Agency, by Travis Goodspeed , as presented at Summercon 2013, inspired by the lectures of Adam Laurie and Jim Geovedi, with kind assistance from Skytee. At Black Hat DC in 2008, I watched Adam Laurie present a tool for mapping Ku-band satellite downlinks, which he has since rewritten as Satmap. His technique involves usin.......

The LTC®6419 is a dual very high speed, low distortion, differential amplifier. Its input common mode range includes ground, so that a ground-referenced single-ended or differential input signal can be DC-coupled, level-shifted, and converted to drive an ADC differentially. The gain and feedback resistors are external, so that the exact gain and frequency response can be tailored to each application. For example, the amplifier could be externally compensated in a no-overshoot configuration, whi.......

The Teledyne LeCroy HVFO103 is a high voltage fiber-optically isolated 60MHz oscilloscope probe that is optimally designed for the measurement of small signals floating on a high voltage bus in power electronics designs. Optical isolation between the probe tip and the oscilloscope input reduces adverse loading of a device under test.   It also reduces noise, distortion, ringing, overshoots, and transients on the measured signal. It far surpasses the measurement capabilities and signal fidelit.......
