An interesting note for these blocks [at least something I was unaware of]. The microblocks in unleashed will block/absorb a redstone signal!
Setting up my bee lab's genepool. DNA gets piped out the top via liquiducts, and the connection needs to be powered. It's located in a corner of the room, so I removed a window and plopped down a redstone torch. Verified DNA was moving, both visually and in the machine's GUI. Then I remembered Unleashed has a version of microblocks, so I threw some glass covers around the torch. Went away for a bit and noticed no DNA was flowing. Machine GUI said "tank was full" but the other end of that liquiduct is a max-size steel tank and I had only just started processing my waste bees. Verified steel tank nearly empty and Tesseracts config'd properly. Then I remembered the glass cover I put between the torch and the pipe. Removed that cover and DNA was flowing again.
I don't remember this being the case for RP2's microblocks and I realize these ain't those. Also, the cover was able to sit inside the same block space as the torch. Also, can't use them to cover over placed redstone dust...unless I'm just doing it wrong?
