Once the project is complete, the next step is to submit an application for review. In this, you’ll need to submit a description of the project and an explanation of how you’ve used the required skills. Additionally, you’ll need to submit a link to your completed portfolio entry for the project.
One of the fields on the application asks for you to submit the link to your project webpage that includes photos and a description. There are lots of free web portfolio resources. Here are some web portfolio resources for hosting your project:
- WordPress.com: WordPress.com is a free blogging platform where you can host a portfolio page for your projects. If you’re working on the digitalharbor.org/wordpress-skill-badge, this would be a good way to practice your skills.
- Weebly: Weebly is another resource that you can use to host a portfolio page for your project. There are paid plans available, but the free plan would be more than enough to host your badge project.
- Tackk: Tackk is another free resource to build out a quick portfolio entry. Tackk has added a lot of social media streams and content, so if you’re using this make sure to monitor this aspect.
If you’re unable to create a webpage for your submission, you can create a Google Document and place your writeup and images in that document. You can then submit the URL for that.
There are several excellent soldering resources out there, but the best way to develop your skills is to practice. Here are some to get you started:
- Soldering Instructable: Great beginning resource with clear instructions and images.
- Adafruit Excellent Guide To Soldering: Detailed guide from Adafruit that includes preparation steps.
