In a post-apocalypse would it be possible for people to recycle e-waste into new products? Booby traps, new makeshift radios or computers, etc. If so what would they need to do so?

Present day electronic is pretty sensitive to ageing. With a smallest feature of 7 nm and decreasing, it doesn't take long for diffusion processes to destroy the artificial path of dopants which is used to create the circuit.
Diffusion is influenced by temperature and time: the higher the temperature, the shorter the time needed for diffusion to take place and jam the component.
Add to this that dust and (dirty) water can also contribute to cripple the components to a point where just a good cleaning will not help. Not counting how many components would be fried by the EMP of a nuke exploded nearby (or by cosmic radiation induced damages).
Depending on your scenario and how long after the apocalypse it is happening, most of the electronic will be gone. What can still be used would have been found in a dry, cold place, possibly underground and protected from EMP.
There would be no need.
Understanding how e-everything works, how to dismantle it, refurbish and re-use would be time and resource consuming.
You want a booby trap? Use a fishing line, 300 metres in one package. You want a new radio? Re-use lamp stuff form the hi-fi store or just Cat's-whisker detector You want a computer? Let me introduce you to math tables (usually printed on...) slide rules.
ALSO: Let's assume that the apocalypse wasn't EMP related. Some usual monkey/zombie stuff. Then you don't need to recycle anything. Just find power generator, fuel and plug that PC in. Hmmm, but Mac would be better as it has compiler built-in so you wouldn't need to look for a programmers PC to write new programs like "how to hunt a rabbit with a 1000 spare RAM".
