We just saw Colin's great video on 555 timers, who doesn't love these classic chips? You can still get them, heck they are one of the few things you CAN get! So, if you want to make a one-shot timer or a mini synth, check out Digi-Key for all your 555 timer needs. They've also greatly improved in performance since the '70s, with wider voltage range, lower quiescent current, and higher frequency outputs.
