No, to many other metals as well - and that's just 'normal' solder, special solders are available that handle stainless steel and aluminium.lord loh. said:Solder adhers only to tin and copper...
Oh yeah!! How could I be so stupid!?! I have a broken pocket radio with the perfect capacitor and knob.Can you not find a suitable value with the
knob inherent? Small transistor radios might
yield up a usable substitute.
Assuming it's an AM/FM radio, you use the FM (VHF) side, which will give the perfect value and range for the FM transmitter. There should be four variable capacitors in the tuning capacitor, two high capacitance for AM, and two low capacitance for FM.Dean Huster said:Zach, the cap from the transistor radio that you're pursuing will have anywhere from 10 to 100 times the maximum capacitance of the trimmer that you illustrated. That can make it very difficult to adjust if a portion of its range happens to cover what you need. In addition, its minimum cap value may actually be MORE than the maximum cap value of the trimmer, making it difficult to use in your original circuit unless you slide another cap in series with it.
