  • where did you get that pre-board base, it seems a digital lab...

  • @dannyhd29 You are right... it's a multi-purpose PCB developed by a team at Singapore Polytechnic. The breadboards are the standard $5 ones you can buy easily. Nothing too high-tech. The data switches and other inputs go via TTL gates for buffering/minimising short-circuit damage. You can easily put one together yourself!

  • @axel1973w Exactly. I came here for the Schmitt Trigger explanation too. :| He could easily do what he did using 4011 :|

  • so... where is the Schmitt Trigger explanation ? where is the tutorial? how to wire up things is not that interesting. but how to read a datasheet and what sections are most important would be more interesting. i still dont know what a Schmitt Trigger is. DONT GET ME WRONG! I like your vid. its HD, it got good sound, but the topics or sections in there are not very educational in this one. would love to see more from you focusing on more detailed content.

  • that is a pretty cool looking development breadboard!
