So I'm not sure if this is a common occurrence in pcbs or maybe in very small scale pcbs, or if ones I'm showing are just more budget level of design. Can anybody help me with feedback on my two possible ways provided in terms of it being a extreme No-No that I'm not aware of because of a beginner …

[image] mythn7: is this actually a mounting hole? Yes, it is a mounting hole. The idea is that you would attach it at the perimeter of a robot chassis. The board looks much too big for a single hole, It might rotate in place. I would say, a lot of modules seem to have mounting holes as an af…

[image] EmilyJane: think you missed the point of @J-M-L ’ s suggestion to use the plastic nuts/standoffs. They would not create any chance of short circuits as they are non conductive. There is no need to “tap” the circuit board mounting holes as there is a nut on the other side from the threaded…

Thank you the last three comments are very helpful, most of my questions are very awkward to ask making it ever more Awkward to answer in a way that actually helps me as I have a learning disability and all of my frustrations tend to form in the realm of the physical concept self plugging all this s…

thanks for the context. There is ton of fun to have without even going to build something "finished" (even if it's nice to have a finished product) - just using a breadboard and Dupont Wires. Make sure power is applied where it's due and look twice for shorts. Unfortunately getting a bit of magic …

Holy crap those look cool, and $$$ tho lol. I think i found something that will getcme by till i can find an affordable source of 3d printing. Started by making this using popsicle stick under tape to bind all the pin cubes in a line as if a single peice, then pinched these out of my helping hand…

[image] mythn7: Would anyone consider being my mentor for all this stuffs? Well, you have quite a few volunteers on this site that do just that. Ask your hardware and software questions and you will get a myriad of responses. For electronic hardware stuff go thru the 1000+ posts on this th…

If the print shop is looking at that view, a very big cost is that nearly every component is a different color. That means each part is going to be printing individually, followed by an employee spending the time to change filament color. A printer with multiple heads would help, but that would ne…

No they know that tinkercad picks s diff color automatically when imported. Each of those patrs actually has a separate stl, i just did that mash up for the est cost as i file to send them.

Blind Mounting Screws for PCB Stand-Offs The following describes a simple method for making effective low profile mounting feet for PCBs. ______________________________________________________________________________________________________ Mounting feet. 1/4” wide acrylic plastic strips are made with a CNC machine or a router. A centered 1/8” dado is made down the length of the 1/4” strips. These strips are .064” thick with the dado set to .032” Drill centered (on the dado) M2 holes every 1/…

4 component mounting shoes: [Fourteen.jpg] I like to use a standoff that is a bit longer than the material is thick. [Sixteen.jpg] Video speed has been sped up. [642F1132-7125-4BC8-975A-FBCE222516A3.gif]

Blind Standoffs, Mounting Feet for PCBs See also, post #1110 We have covered chassis PCB mounting without the need of drilling through the chassis itself. This method used a M2 brass insert in an Acrylic foot; the height of the finished foot is about 3.5 mm. The assembly is glue welded with DCM (Methylene Chloride) to the chassis inside surface. There are, however, times when the 3.5 mm brass insert foot is too high. See also: About 6 months ago I ordered Phillips M2 FLAT headed …

Tightening a Nut on a Blind Standoff Screw See also post #1110 It is very difficult to tighten a nut on a screw when you have no access to the screw head. A while back we discussed making a blind standoff. The nut used in the blind standoff can be quite difficult to tighten as the screw rotates. Using a modified brass standoff, we can make an effective tool to easily accomplish this task. Note: the brass standoff is made from brass and is tapped for an M2 thread. The very useful razor saw…

Convert a Stand-Off from One Thread Type to Another If you have a selection of threaded brass inserts, use these to modify an existing stand-off thread. The following images show the easy process. Simply compress the brass insert into the stand-off hole. You may have to enlarge the hole to accept the brass insert. You can also heat insert using a soldering iron. [A] [B] [C] [D] BTW Old Bic pens make nice stand-offs; add a brass insert to these too. [image]
