    Useful books about electronics and telecommunications

    I'm eagerly awaiting the 3rd edition as well ;-) Just out of interest, what architecture would you propose as a suitable alternative to the 68008? I'm not sure a Microcontroller would or should cut it as it doesn't show you how it works and cannot be programmed standalone i.e. without a...

    Useful books about electronics and telecommunications

    I don't know why people complain about The Art Of Electronics. Yes it's relatively old but it covers everything adequately. Not that much has changed from a theory point of view and it still covers tangible things and not virtualized components such as FPGAs and DSPs. I will say that the...

    Decent calculator to replace TI92

    I'm rather fed up of the screen and the lack of decent unit support on my TI92. I looked at a TI Voyager 200 but it's a little pricey to be honest. Is there anything newer with a decent CAS, native SI unit support that can handle boolean types?

    [SOLVED] 1 Hz clock pulse for digital clock

    You could do it with a simple 32.768KHz XTAL oscillator then divide it a few times with a prescaler/divider or a chain of D-type flip-flops (ripple counter). However, TTL really is a waste of time here. You can use a single 74HC4060 as an XTAL oscillator (at 32.768KHz) and a 14 stage...

    Going on a retro kit mission

    It's a hobby for me now. It was a living for about 10 years but I got dragged into management (which I hated) and then inevitably software. Things were good if you ask me. Only because they were simple. I'm only a fan of the old kit as if you throw $15k on a nice new LeCroy scope and it goes...

    Going on a retro kit mission

    Firstly - Hi this is my first post. Posting this is more of a validation exercise to make sure I'm not insane. I'm getting rather frustrated with the non-availability of certain integrated circuits. There seems to be a complete vacuum of formerly useful ones. Particularly OTAs and a lot of...
