Black Beauty` is my nickname for this classy Bakelite set. Sporting a dramatic, assymetrical design, with deep wraparound louvers and a bullet-like profile, it`s a great example of 1940s Streamline design. Definitely a keeper, in other words! I`m restoring the electronics of this radio as well as the cabinet, so let`s look at some highlights of ea

ch process. This radio came from the factory with an ivory paint job. By the time I got my hands on it, though, the paint was deeply chipped in many places. After spending some time trying to smooth out the chipped spots, many of which were on the delicate edges of the louvers, I gave up and removed the paint with a chemical stripper. I don`t normally resort to such drastic measures, but the original paint simply wasn`t salvageable. Before removing the old paint, I brought the cabinet to an auto parts store and found a can of spray paint that looks like a great color match. When it`s time to repaint, I`ll have exactly what I need. I also carefully masked the bottom to preserve the original paper labels. I first taped a layer of plastic over the labels, using blue "painter`s" masking tape, then covered that layer entirely with a second layer of tape. Stripping the cabinet took a couple of hours. I worked outdoors on our deck, using a brush-on liquid stripper. From aluminum foil, I formed a temporary container about the size of a cakepan to catch the excess stripper and old paint. Most of the paint brushed off after softening, but a few areas required some careful scraping. For the flattish areas, I used an old putty knife that once belonged to my grandfather. For close crannies and details such as the raised Farnsworth lettering, I used various smaller tools, including toothpicks and a straight pin. Click the thumbnail...
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.....
