[@hybridjohn1]

love this book

I built everything, and I mean everything, from the 1st edition. I still have Charles Platt's Make: More Electronics, to work through. Forget about 2nd and 3rd editions of Make: Electronics. But I'm still going to watch your videos. Cheers!

Hi Laurence, Thank you for your work 😍 I'd like to buy the 3rd edition of the book AND the kit. (Already have the 2nd ed. in PDF.) Would you recommend buying the kit (which is quite exoensive, 100 GBP in the UK) or just to buy a cheaper kit and other parts for the experiments? Thank you.

I haven't bought the kit I'm afraid, so it would be a bit unfair of me to comment on its value. I'm sure, in the long term, it's likely to be more expensive to source individual components, as you are generally buying more than you need for just these experiments. That being said, I do like to have spares to hand, especially for things that are easily damaged such as logic chips - I've managed to fry a couple of those just by being careless with letting wires come lose and brush across pins while the circuit was powered.

I think this is a book I'm going to get

I don't have any edition so I don't need to worry.
