Some IT focused DIY articles could be fun (original, not copy paste).
Example 1:
Maybe go buy a Raspberry or 6, build them each a custom cover, test them with different peripherals, different os's, applications, environments etc.
Make a few original or less well known devices out of them. Basically instructions as well as final conclusions (you could compare all the Kodi versions out there as an example or make a little server array or whatever).
Then once done (eventually) give them away if you can't use them.
Example 2:
Test similar themed applications and compare, use different os's, brands etc and try to achieve a similar goal.
Example 3:
Build and burn in test some of the hardware you report on.
Example 4:
Build a home network uing wired and wireless technology.
Example 5:
Put in a cctv system.
and so on...
The above need not just be articles, you could turn them into a wiki...
