AM radio built around 555 timer chip. The only active device (silicon, germanium, or otherwise) is the LM555. The tuning is accomplished with an inductor and a capacitor, and the LM555 acts as an AM demodulator and class-D power amplifier to drive the speaker. The TRF radio above operates on the AM broadcast band in the range of 550-1650 Khz. It's similar to a crystal radio with the addition of a couple buffer stages and audio amp to drive a speaker. Reception is limited to strong local stations. KFI (Los Angeles) comes in loud and clear at a range of about 7 miles from the 50KW station.

Of these, UpHere has come up with the UpHere RGB123-5 120mm RGB Wireless fan that is similar in that it offers two-way lighting. Unfortunately, customization is much reduced since lighting is set with the included remote, but UpHere is a relatively reliable brand and at $35 for a five-pack (or $7 a fan), it is hard to complain. Likewise, the writer had no receiver which could tune these frequencies and set out to design a simple receiver for just that purpose. The superheterodyne receiver described is the result. It has been designated a VLF-LF receiver, because it tunes the VLF-LF range from 10 to 300 kHz, but it also tunes part of the MF spectrum from 300 to 500 kHz. Mar 28, 2014 · AM receiver with TA7642.
