For some motor vehicle lovers whose passions run in direction of older autos, only originality will do. [RetroJDM] for instance has an RA28 Toyota Celica from the mid 1970s for which he has absent to excellent lengths to source a pristine heart console to replace a weakened first.
There is only 1 issue with the center console on a 1970s Toyota, it doesn’t have a DIN lower-out for the typical-sized motor vehicle radios that have turn out to be common in the a long time considering that its manufacture. In its place it has a minimize-out for a Toyota-certain radio in the aged style with holes for volume and tuning knobs to possibly facet of a protruding heart unit that would have contained a tuning dial and a slot for cassettes or possibly 8-monitor cartridges.
His answer is an intriguing one particular, he’s set collectively his very own auto stereo in an enclosure ideal for the Toyota minimize-out. Within the radio there is an Arduino Mega controlling the breakout boards for an Si4703 FM tuner and a VMusic3 MP3/USB audio player, and a PT2314 audio processor. For show there is a established of retro LED 7-section modules, and an MSGEQ7 spectrum analyser. The outcome is a fashionable radio with FM, line-enter, and MP3 player, with all the capabilities you’d expect. There is no onboard amplifier nevertheless, but this purpose is fulfilled by an exterior unit.
The finished unit is topped off with a incredibly professional entrance panel, which you can see in his demo video clip below the crack.
We’ve had extremely couple motor vehicle radios from scratch below at Hackaday, but we have experienced extra than one particular bluetooth update or addition of a line-in port.
Many thanks [Darkspr1te] for the story.
