What is Local Hack Day: Share?

Local Hack Day: Share is a week-long celebration of sharing everything you’ve learned as a hacker. If you’ve been hacking with us all year, we’re excited to have you back. If this is your very first event, we’ve got a ton of beginner-friendly challenges for you to complete that’ll have you shipping your hack like a pro in no time. You’ll have your pick of technical, design, and social challenges to complete - each with an emphasis on sharing your work. The more challenges you conquer, the more points you’ll earn. Tune in each day to check out the leaderboards and share what you’ve built. To start hacking at LHD: Share, register here. 

What are these Challenges?

Local Hack Day: Share will run from Sunday, March 28th to Monday, April 5th. During this time, you can expect challenges for all skill levels. We will have plenty of both week-long and daily challenges to keep you busy. Week-long challenges will be accessible for the entire week, so you can hack on them whenever you have free time. Daily challenges are only available for 24 hours after they’re originally posted, so make sure you come back each day to see which challenges you’re going to conquer. 

Challenges will range from social challenges urging you to connect with other members of the community, technical challenges that will expand your coding skills, and design challenges to refine your skills as a creator and artist. We cannot wait to see all you learn, build, and share.

Hackathon Sponsors


Redesign Your Favorite “Sharing” Site

Ever been frustrated with how a website was laid out? We want you to pick any website and imagine a new layout for it. Specifically, pick a website or application designed to let you share (twitter, devpost, whatsapp, product hunt, etc) You can simply draw it out, wireframe it, or even write the HTML/CSS if you’d like.

Build Something to Reduce Single-Use Plastic

One of our favorite hacks to see built are ones that help the planet. We think these projects are common to see at hackathons because they’re genuinely useful for the world. Create one of these - it could be an application that helps folks understand how to recycle their plastics, or even a prototype for a reusable item that will replace a single-use one.

Create a Music Visualizer

You might listen to music while hacking, but have you built anything to elevate your music listening experience? Try building a project that visualizes the music you’re listening to.

Make a Sports Analyst Hack

Create a hack that analyzes a sport you enjoy. The sky's the limit here - you could have an AI watch and analyze footage, a database store scores, or any other analysis you think would be fun to implement.

Use Weather Data

Create a project that uses weather data to do anything you’d like. Maybe you’ll suggest a commute based on the weather, predict future weather trends, or pick out the best days to plan a picnic on.

Use the Largest Tech Stack in a Demo

How many technologies can you fit into a demo video? Push yourself and submit on Day 2 Devpost (and yes, you can count Devpost in your tech stack)

Redesign your Favorite Mobile Application

Ever been frustrated with how an app was laid out? We want you to pick any mobile app and imagine a new layout for it. You can simply draw it out, wireframe it, or even write the code if you’d like.
