Clock Module

The idea behind this project is to have a standalone clock circuit to debug ICs at a very low clock speed.

It is mainly inspired by Ben Eater's version.

Features

• Manual pulse Mode.
• Variable frequency clock.
• DC Input Jack 7v - 15v @ approx. 100mA.
• Raw 5v power in for breadboard compatability.
• Lots of LEDs :)

• 2x 0.01uF - Ceramic Capacitor
• 2x 4.7uF - Capacitor
• 1x 470uF - Capacitor
• 1x .33uF - Ceramic Capacitor
• 4x .1uF - Ceramic Capacitor
• 1x 1uF - Capacitor
• 1x 1N4007 - Diode
• 4x 5mm LED
• 2x 01x02 Female Pin header
• 1x DC Jack
• 6x 1K - Resistor
• 2x 51K - Resistor
• 2x 10K - Resistor
• 1x 100K - Potentiometer linear
• 2x Button
• 3x NE555P
• 1x L7805
• 1x 7400

What does it look like

KiCad Render

Todo

• Use CMOS ICs for a 5vpp output
• Add partslist
• Add photos
• Swap silkscreen position of c3 and c4
• Different footprint for c8
