So, you wanna build your own electric skateboard but you're on a super tight budget? No worries, guys! It's totally possible to create a DIY electric skateboard under $100. It's going to take some resourcefulness, a bit of elbow grease, and a willingness to compromise on top-tier performance, but the satisfaction of cruising on something you built yourself? Totally worth it. Let's dive in!

The Challenge: Staying Under $100

The biggest hurdle is, of course, the budget. Electric skateboard components, especially motors, batteries, and ESCs (Electronic Speed Controllers), can get pricey real fast. To stay under $100, we need to get creative, think used, and prioritize essential functionality over bells and whistles. This means we'll be looking at repurposing parts, making smart compromises, and potentially sacrificing some speed and range. The goal here isn't to build a competition-grade e-board, but rather a fun, functional, and affordable ride. Consider this your entry point into the world of electric skateboarding. Once you get the hang of it, you can always upgrade components later! Remember, safety is paramount. Even on a budget build, ensure your brakes work reliably and wear appropriate safety gear like a helmet, knee pads, and elbow pads. Don't skimp on safety. Shop around for deals. Websites like eBay, Craigslist, and even local classifieds can be goldmines for used parts. You might find someone selling a used scooter or electric bike with components that can be repurposed for your skateboard. Be patient and persistent in your search. Don't be afraid to ask for help. Online forums and communities dedicated to DIY electric vehicles are full of knowledgeable people who are willing to share their expertise. Ask questions, seek advice, and learn from others' experiences.

Key Components and Budget Breakdown

Here's a rough breakdown of the key components you'll need and how we'll try to keep costs down:

• Deck: (Free - $20) - Use an old skateboard deck you already have, or find a cheap one at a thrift store or garage sale. You might even be able to snag one for free from a friend or neighbor.
• Motor: ($20 - $40) - This is where things get tricky. We'll be looking for a used scooter or RC motor. Keep an eye out for deals on eBay or at local repair shops.
• Battery: ($20 - $30) - Used laptop batteries or individual Li-ion cells can be salvaged. Be extremely careful when working with lithium batteries, as they can be dangerous if mishandled.
• ESC (Electronic Speed Controller): ($15 - $30) - A cheap ESC from an RC car or airplane can work. Again, eBay and RC hobby shops are your friends.
• Wheels & Trucks: (Free - $20) - Use the ones from your existing skateboard or find used ones. Scour local classifieds and thrift stores.
• Other (Wires, connectors, etc.): ($5 - $10) - You probably have some of this stuff lying around. Otherwise, a trip to your local electronics store is in order.

Important Note: These are estimated prices. The actual cost will depend on what you can find used and how resourceful you are. This project requires basic electrical and mechanical skills. If you're not comfortable with wiring and using tools, get help from someone who is.

Finding the Right Parts on a Budget

• The Deck: The skateboard deck is arguably the easiest and cheapest component to acquire. If you already own a skateboard, you're set! If not, check out thrift stores, garage sales, flea markets, or online marketplaces like Craigslist or Facebook Marketplace. You might be surprised at the deals you can find. Don't worry too much about the condition of the deck, as long as it's structurally sound. A few scratches and scrapes are nothing to be concerned about. You can even paint or decorate the deck to give it a personalized look.
• The Motor: The motor is the heart of your electric skateboard, and finding a suitable one for under $40 requires some creative thinking. One option is to look for used scooter motors. These can often be found on eBay or at local repair shops for a reasonable price. Another option is to consider RC car or airplane motors. These are typically smaller and less powerful than scooter motors, but they can still provide adequate performance for a budget build. When choosing a motor, pay attention to its voltage and current ratings. You'll need to select a battery and ESC that are compatible with the motor's specifications. Also, consider the motor's mounting options. You'll need to find a way to securely attach the motor to your skateboard deck or trucks.
• The Battery: The battery is another crucial component of your electric skateboard, and it's essential to choose one that provides enough power and range. Used laptop batteries are a popular option for DIY electric skateboard builders because they are relatively inexpensive and readily available. However, it's important to exercise caution when working with lithium batteries, as they can be dangerous if mishandled. Make sure to research the proper safety precautions before attempting to salvage or use laptop batteries. Another option is to purchase individual Li-ion cells. These cells are often used in power tools and other electronic devices. They are typically more expensive than used laptop batteries, but they offer greater flexibility in terms of voltage and capacity. When selecting Li-ion cells, make sure to choose ones that are rated for high discharge currents. You'll also need to purchase a battery management system (BMS) to protect the cells from overcharging and over-discharging.
• The ESC (Electronic Speed Controller): The ESC is responsible for controlling the speed of your electric skateboard motor. It takes the signal from your throttle and converts it into a voltage that the motor can understand. A cheap ESC from an RC car or airplane can work for a budget build. These ESCs are typically designed for brushed motors, but you can also find brushless ESCs for a reasonable price. When selecting an ESC, make sure it's compatible with your motor's voltage and current ratings. You'll also need to choose an ESC that has the appropriate connectors for your motor and battery. Consider the ESC's features. Some ESCs have features like regenerative braking and reverse. These features can enhance your riding experience and provide additional safety.
• Wheels and Trucks: Reusing the wheels and trucks from an existing skateboard is the most budget-friendly option. If you don't have a spare skateboard, check out local classifieds, thrift stores, and pawn shops for used wheels and trucks. Look for wheels that are in good condition with minimal wear and tear. Make sure the bearings are smooth and properly lubricated. Inspect the trucks for any signs of damage or wear. Check the bushings and pivot cups for cracks or deterioration. If the bushings are worn, you can replace them with new ones to improve the skateboard's handling.

Building Your Budget E-Board: Step-by-Step

Okay, let's get down to the nitty-gritty of actually building this thing. Remember, this is a general guide, and you'll need to adapt it based on the specific parts you're able to find.

1. Prepare the Deck: Clean and sand the deck. You can paint it or add grip tape if desired.
2. Mount the Trucks: Attach the trucks to the deck using the existing mounting holes. If necessary, drill new holes.
3. Motor Mount: This is the trickiest part. You'll need to fabricate a motor mount that securely attaches the motor to the truck. This might involve some metalwork or creative use of brackets and clamps. Ensure the motor is aligned properly with the wheel.
4. Wiring: Connect the motor to the ESC, and the ESC to the battery. Double-check all connections and polarities. Use heat shrink tubing to insulate exposed wires.
5. Mount the ESC and Battery: Find a secure place to mount the ESC and battery to the deck. Consider using zip ties, Velcro straps, or a small enclosure.
6. Throttle: Connect the throttle to the ESC. This will allow you to control the speed of the motor. Test the throttle to make sure it's working properly.
7. Test Ride: Before you go full throttle, test the board in a safe, open area. Start slow and gradually increase the speed. Check for any loose connections, unusual noises, or overheating components.
