    PCB mounted to aluminum enclosure without standoffs

    Thanks for letting me know its common as I didn't see any issue with it but struggled to find an example . The high voltage warning is appreciated as well

    PCB mounted to aluminum enclosure without standoffs

    Hello, I was wondering if anyone can think of a reason why this is a bad idea as I project that has a board that gets very hot and was thinking having more surface area between the board and case (heatsink) would be good. I feel like I am missing something obvious but can't think of a reason...

    Moving Target on rail system design discussion

    itsmoked That's a great size and you mentioned and I will PM you if I go down this route. It does seem like a solid option and more inexpensive and versatile than a sled rail system As for the positional accuracy I need to get this requirement better defined, however, my guess would be around...

    Moving Target on rail system design discussion

    Thanks for all the input and with positional accuracy being important I am going down the design route of using a laser range finder so I have an accurate position when measurements are taken and can greatly open up the mechanical positional constraints which would be very challenging and costly...

    Moving Target on rail system design discussion

    Thanks for all the replies and I wish I had more information but I am just beginning this design and currently have limited requirements. I was thinking of used two tracks but the position of the tracks in relation to one another sounds like a real headache vs. a single track. Some...

    Moving Target on rail system design discussion

    Yes. This device is moving horizontally so this view is from the top down. The trolly will have a small vertical load on it but shouldn't be more than 10#. The motion will be stopping at discrete distances for a short time and then moving to next distance so being able to control motor is...

    Moving Target on rail system design discussion

    Thank you for letting me know about upload (I have attached drawing here). I thought about that as well and with long distance having the motor on the track using a rotating wheel on the track could make sense, however, the distance to the target is critical and although it can be calibrated...

    Moving Target on rail system design discussion

    Hello, I am working on a target system that needs to move lineally and have a few things I would like to ask the community about. Attached is a simple diagram of the system but it is basically a cart that attaches to a rail using a carriage ( either roller bearing carriage or sleeve...
