I had never heard of the system that this radio used to be used on. It was tied into the telephone system and received the audio programming over the phone line. Since this system has been discontinued the 1953 Radio was upgraded to play MP3s and FM Radio. The neat thing about the conversion is that it still uses all the original electronics to make the sound so it still
Kiriakos Triantafyllou from Volos – Greece is a 40 years old Industrial electrician. He shares this project on the EEVBlog Forum which shows us how he built a professional looking DIY Resistors Decade Box. Have a look at some of the very neat wiring, I am thinking this looks better than some of the vintage electronic gear I have taken apart where everything used to be point to point wired.
Frank has completed the next phase in the Dune Bug E Build, we saw the last build update back in May. It is interesting to see what is involved in making a normal differential into a locked differential, this process allows both rear wheels to always be powered with no slipping. The gearing has also been changed increasing the top speed of the vehicle. “Since the internal gear ratios were
Renkku is able to take some great action shots with this PIC AXE Microcontroller based High Speed Photography Trigger. The system is connected to a flash unit and triggers the flash as soon as it hears something. This makes the unit very flexible since it can then listen for almost anything. If you want to see more of these type of cool images have a look on Flickr. “I hacked
All speaker systems need a housing of some sort. Normally we see boring wood boxes with some holes cut in them so that round speakers could be mounted into them. There are a few companies who make some speakers which are not just boxes with holes such as the Bazooka Tube Subwoofers. Instructable user djairjr had an old vacuum cleaner which had reached the end of its life. After cleaning
Mike Szczys from Hack a Day shows us how to Programming Launchpad MSP 430 with Linux. The basic method that people use to program their Launchpad MSP 430 is a Windows box but for those on Linux there is still hope. “We’ll be working with Ubuntu 10.04 Lucid Lynx. When the Launchpad is connected to USB it is identified and mounted to /dev/ttyACM0. It’s not immediately apparent how to use
If you are into audio electronic projects have a look at this ECC802S Shunt Regulated Push-Pull Tube Preamplifier. One thing about these tube amp builds is that the housing looks just as nice as the circuit construction. Thanks Gio. “After the success with the various Odd Block amplifiers that used a SRPP (shunt-regulated PP) driver stage I started to do some research and modeling on a SRPP. The advantages of
