Hi all,
I’ve finally updated my mechanical logic gate pages with a couple of new
(ish) creations. The XOR gate and the Half Adder. You can find them by
going to http://www.goldfish.org.uk/xor.html and
http://www.goldfish.org.uk/halfadder.html.

Nice work Martin! I’d point out a typo in the text for your 1/2 adder though
- you say “1+1 = 1, carry 1”, the sum should be 0 :)

Thanks for the comments and pointing out the typo.
Martin

Well, technically, 1 + 1 = 2, or in binary, 1 + 1 = 10. The sum isn’t 0, the S
output is 0.

This stuff is cool. I like your mechanical logic gates better than the pneumatic
ones I’ve seen. Yours are definitely cheaper to build.

| So basically, when designing a mechanical walker, the use of these types of adder/half adder creations is to see how the machine will walk? I ask because I have never built a walker. (19 years ago, 12-Mar-06, to lugnet.technic, FTX)
