7400 competition entry: Signal strobe
Check out Matthew’s 7400 contest entry, a 74xx based signal strobe for emergencies, as well as search and rescue situations.
This a signaling strobe, an enhanced one with a siren. My device is built off of 7400 NAND Quad Gate, 2x 7476 J/K Flip Flop, 7432 OR Quad Gate and 4x 555 Timers. Now of course, there are a few passive components like capacitors, resistor, 5 volt regulator, LEDS, and several switches. All built on one large breadboard, but I believe this could be fabricated on a 2×4 PCB, maybe smaller
To be able to complete the project for the 7400 competition, I wasn’t able to find locally the I/R diodes or the high output LEDs that will be mentioned later. I will go over it POU, point of use, and a bill of material will be included at the very bottom.
