Need help with cards

[Fenster]

Cards that can produce artifact tokens and doesnt rely on any color but {U}
For example {Thopter foundry} without {b}{W}

[Double-O-Scotch]

{pentavus}

[scarsabrex]

{Sharding sphinx}
{thopter assembly}
{nuisance engine}
{summoning station}

[Fenster]

I like i like!
{Summoning Station} doesnt make artifacts though... But! With {mycosynth lattice} its fixed!
Any untapping functions for artifacts that doesnt use non blue mana?

[Greg54js]

{unwinding clock}
{voltaic key}
