Always put your accomplishments on your resume. Here's a few thoughts:
1. You never know who will find what valuable.
2. Even if it has the tiniest bit of relevence to your desired career path, it has value. But...
3. Don't give it more value than it really has. OK maybe a little more, but just because it is on your resume doesn't mean that you are claiming it as experience. Put it in the training and education section.
Those in a position to hire for tech jobs (especially if they have tech experience themselves) love to see that you are taking an active role in your own career in your spare time. That shows drive, initiative, willingness to learn and more.
So put it on there and don't look back.
Hope this helps,
