LED Cylon Scooter – 80s Larson Scanner

This project is a very 80s upgrade to a very 80s scooter– I’m putting an LED strip in the grill of my boyfriend Smokey’s Honda Elite to create a larson scanner animation effect while teaching him how to solder.

Supplies

For this project I used a strip of WS2812b LED strip, also known as NeoPixels. I chose the densest variety to pack as many LEDs in as possible for a nice smooth animation effect.

Easy LED Circuit

Today I’m going to show you how to create a simple yet customizable LED and battery circuit that’s perfect for putting inside your next project. This is a great first soldering project! Follow along with the video to practice your technique.

The most basic LED circuit can be made by sandwiching the legs around a coincell battery. This is also a good way to identify the positive and negative legs of the LED since it will only light up one way. That’s because LEDs are diodes, which allow electricity to flow one way, but not the other. The positive side of the battery should be touching the positive, usually longer, leg of the LED.

Put a little tape on it, and you can enjoy the glow for about a day before it gradually dies out. This is a hacky way to add LEDs to projects that only need to work for a short time, like costumes and props.

If you want to create a durable circuit, it’s time to bust out that soldering iron. In addition to your LEDs, you’ll also need resistors, some wire, some heat shrink tubing, a three-cell battery holder, either triple-A or double-A, and a switch, if your battery holder doesn’t have one already.

GH5s Studio Setup – My Camera Gear 2020

Here’s a comprehensive list of the gear I use to capture and edit my DIY projects, tutorials, and videos. My tool selection is optimized for my photography and videography practice and has been built up and refined over a long time. I maintain the advice that the best camera is the one you have access to, and you can get really far using just your phone these days.

Slack Status Updater

This project helps make your day a little easier if you’re a remote worker using Slack. I’ll show you how to build it using an ESP8266 wifi board. Don’t miss the video above for the overview.

Whether you’re new to using Slack or you’ve just been using it a lot more lately, you’ll understand the importance of setting your Slack status. It lets your colleagues know if you’re available to chat, in a meeting, out sick, etc.

Forget to set it when you leave your desk, and you may get interrupted by somebody who thinks you’re available. I thought it would help me remember to have a physical device on my desk that can set my Slack status for me. This project is a collaboration with Brian Lough, who’s an ESP whiz and author of many Arduino API libraries including this new one for Slack. You might remember my YouTube subscriber counter, which was also written using one of Brian’s API libraries.

If you’re new to Arduino, try my free Arduino class first.

Maple and Epoxy Resin Bedside Shelves

This project is a pair of bedside shelves made from maple and epoxy resin. This wood has a bunch of beetle holes in it, some of which I filled with silver wire as an accent. Let’s get started.

Hunter Cat Card Skimmer Detector Review

Today I’m reviewing Hunter Cat, a business-card sized circuit designed to root out magnetic card skimmers. Thieves use skimmers to collect your bank card information, most commonly at ATMs and gas stations.

Dip the Hunter Cat into a magstripe payment device and it will tell you with some small LEDs whether it’s safe to dip your bank card.

It works by detecting the number of magnetic stripe heads inside the reader. Too many and the Hunter Cat will tell you it’s suspicious.

I keep my Hunter Cat in the dash compartment on my scooter, since I’m most likely to need it when I’m getting gas, but if I were traveling, I’d carry it with me to identify safe ATMs.

Hunter Cat is a collaboration between Mexican hardware company Electronic Cats and security researcher Salvador Mendoza.
