Is there someting to improve in this design? - Milliohm meter
Arek_R:
Hi I'm making Milliohm meter basend on the design from "Scullcom Hobby Electronics" youtube channel:
And I was thinking if there's something that I could do better on my schematic, any suggestions?
spec:
+ Arek_R
Hell, that is a nice piece of engineering: very professional. :)
Attached is another approach, which I have had on the back burner for a while. Thought you may be interested. The schematic is hot off the drawing board, and has not been prototyped or tested, so it may have some errors, but it's the principle that I am trying to convey.
Arek_R:
Thanks :D
That looks like a EEVblog electronic load xD
It's a good idea as well, but I will stick to my concept as I have all the parts and I like it, was just asking maybe swap one or two components and add something there and there.
spec:
Let us know how it goes. :)
Gyro:
Here's a Maxim app note (AN106) that shows a possible alternative current source. Deriving the test current from a 1.5V cell would offer a longer life than step-down from a 9V battery. Ref, opamp and mosfet can of course be substituted.
