Re: Young Engineer
There are a few around. I'm privileged to be in contact with one, who has an astonishing grasp on theory, building (and understanding) FM super-regens at 12 and exploring relative merits of pentode, cascode, and grounded-grid triodes as preceding RF amplifier.
Now at 13 she's been building step-up converter, 12V to 90V, using a tapped-inductor boost converter topology, eschewing off-the-shelf custom IC's and using a pair of 555's and a TL431 as reference/error amplifier, to produce a battery version of the super-regen.
However, this is on temporary hold due (a) to outdoors weather, and (b) her friend's Ford Fiesta has collapsed front suspension so she's replacing the suspension units after another friend (temporarily incapacitated with knee injury) removed the old after a struggle with rusted nuts.
There's hope for the future!
