Making a light dimmer (triacs) with 110v instead of 220v?

[ostef]

Hi everyone, well my doubt is the next one, I was searching for a simple project I could make with triacs and I found this one.

Well the diagram says it will work with a 220v AC , but in my house the electrical connection is of 110v, my main doubt is will this work with the previous diagram, or will I need to make any modifications in it?

Thanks a lot guys, any comment is appreciated.

Should be ok as is. C1 and C2 values presumably are in pF, i.e. C1 = 47000pF =47nF and C2 = 100000pF = 100nF.

I found a somewhat similar circuit with the following diagram for 117 VAC, I just found out that in my house the voltage is 127VAC, will it be ok to implement it? or still would I need to modify it?

Couldn't find data for the 40502 triac. May be obsolete? If so you could use a BT136, BTA06_600TWRG, 2N6075BG etc instead. The other components are fine as is.
