Compact Warning Flasher


Compact Warning Flasher
This little project should give peace of mind to bicycle riders pedaling in the dark without street lighting. At the same time it provides early warning to faster, motorized road users to pay attention and pass with care.

Lesson 7: How to build the circuit

It's build day! That's the best day of the week. But first: Have you ordered the components yet? If not, go back to lesson 6 to see how to get your hands on the right components. In this lesson, I'll show you how to build the blinking light circuit. Let's start with the complete circuit diagram: (The numbers next to each pin in the diagram represent the pin number of the Hex Schmitt Trigger Inverter.) Component List: BATT1: 9V Battery U1: Hex Schmitt Trigger Inverter (74C14 or CD40106) C1: Polarized Capacitor (100μF) R1: Resistor (10 kΩ) R2: Resistor (10 kΩ) LED1: Light-Emitting Diode (low power) Breadboard Connections: If you just want to know how I connected it on my breadboard, here's how: Step-by-Step Instructions: I've created step-by-step instructions that will explain each step I did to arrive at the connections shown above. And you can use the comment section to ask questions if you're struggling to get

Lesson 6: Getting components

It's time to get your hands dirty! So far you've learned how to blink a light on paper. But the real fun is in building it. The first circuit I ever built was a blinking light circuit. I built it with my dad in our basement when I was around 13. Seeing the circuit working for the first time was such an amazing feeling! So in this and the next email, I want to help you build the circuit. I can't stress enough how important it is to build things, not just read. How do you build things with electronics? You need to have the components for the circuit. Most of the components can be found for a dollar or less. I'll show you where to get them soon. AND - you need a way to connect the components as shown in the circuit diagram. To connect the components, you could either solder them onto a prototyping board - or you could use a breadboard. I recommend using a breadboard. It's quick and easy to build a circuit. And you can reuse the c
