My dream would be to know enough to be able to reverse my favorite electronic device, a Casio Ex-Word dictionary. I uploaded some PCB pictures here: https://electronics.stackexchange.com/questions/522340/unknown-component-in-an-electronic-dictionary/522344?noredirect=1#comment1344263_522344 https://electronics.stackexchange.com/questions/522340/unkno... It's such an advanced piece of equipment, and I'm unable to find most of the components listed on it, plus the major processors are under epoxy blobs. I feel totally overwhelmed just looking at it and not knowing where to start. I wish I could have an expert examine the device with me in real life and help me walk through it a bit; using random bits of online resources still leaves me feeling lost. I would love to have a resource that teaches elements of hardware hacking step-by-step by reverse engineering cheap electronics I can get my actual hands on, starting with simple and moving on to complex items.
