Those are absolutely amazing, brilliant job!

I worry that my meds are in need of adjusting, since I seem to be losing focus. I dithered about making new shoulders or new fenders, even though I don't really NEED either. I've started on the fenders for no good reason, but if I go as far as making the full set, I will need to upgrade my wheels. I think it will also restrict my transport options. Having to seriously consider the trailer purchase, which means getting a tow bar fitted. That DOES mean that we could transport the whole team along with the dalek in one vehicle, but I don't know what the protocol is for parking a vehicle with trailer in public car parks. Do you take up two spaces and pay twice?   Anyway, here's the six pieces I have printed so far. I'm going to need more nuts and bolts too, I guess...  

Today I have 3d printed epsilons gun. I have seceded once again to not do a grey Dalek as I will be making a death to the daleks leader with all the quirks such as the shortened neck and the machine gun. Due to some problems with adhesion on my a1 3d printers bed the barrel of the gun got knocked off mid print so I’m currently printing the parts that are missing but for the most part the gun is done of course I still need to sand, paint and assemble the whole thing. Today i was planning to go to my local diy shop and purchase a sheet of hardboard to draw out the skirt pannels and holes for the hemis so I could take it back tomorrow and have it cut but alas in classic British tradition my plans were ruined by a thunder storm and some pretty heavy rain meaning that epsilon will have to remain in his gun and eyeball form for a few more days until I have a gap of good weather.

Thanks for that @bertus since the op amp will be using a single rail power supply. Maybe you can do a simple schematic if possible as my one is wrong. I  just tried watching a video on op amps and biasing with signle rail voltage it I got lost.   Thanks for your help,
