Many thanks to SWLing Post<\/em> contributor (and certified mad scientist), Emilio Ruiz, who writes:<\/p>\n

Recently I was given a broken Grundig G8 Traveler II.\u00a0 This radio had an accident–the case, speaker, tuning knob, and volume controls were all broken or damaged.<\/p>\n

\"\"<\/a><\/p>\n

I discovered that the tuning and volume controls are not potentiometers, they are a rotary encoders, so I substituted the tiny and broken original controls with rotary encoders (typically used for Arduino projects), but I needed to remove the 10 kiloohms resistor to work properly (only used the CLK, DT, and GND pins).<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

All materials were reused from other things, the result is like a “Frankenstein radio”.<\/p>\n

The “telescopic” antenna is a tape measure\/flexometer which was broken too. I replaced the original speaker (which I think was another impedance) with a proper 8 ohms speaker which produced low volume, so i decide add a Pam8403 amplifier module for best performance. The total current drain is 0.10 amp for a regular “loud” audio level.<\/p>\n

So the Grundig Frankie is alive!!… It’s alive!!<\/strong><\/p><\/blockquote>\n

This is brilliant, Emilio! Although this radio is quite scary–and, let’s face it, “post-apocalyptic”–I think it’s absolutely amazing! I love the handle and the tape measure antenna. You, sir, are a mad scientist and I look forward to your next creation! (I’ll just take shelter first!) \ud83d\ude42<\/p>\n

Anyone else ever created a Frankenradio? Please comment!<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
