Trouble deciding on how to build a LiDAR system for 2D and/or 3D mapping

OVERVIEW OF MY LIDAR PROJECT Three of us are attempting to build a 2D LiDAR (Light Detection and Ranging) system to scan an indoor area or tunnel system. The data will be used to reconstruct a 2D image. If 2D is accomplished within our timeline we…

LCD driver: What changes in 3-D mode?

Facts: We know that a system needs high data transfer speed if it works with +120 Hz refresh rate and +1080p resolution(This mostly requires DVI dual link). We know that in a 3-D system with shutter, the method is to flash for Right and Left eye…

Altium: STEP File of Board with Multiple Layer Stacks Exports Incorrectly

I have been having this issue for some time and have not yet figured out whether it is a user error or an Altium bug. I have a PCB design with two layer stackups: In the Altium 3D view it looks good. You can easily see where the different layer…

How do you measure a distance along the Z axis in Altium?

If you hit CTRL+M, it's easy to take a measurement along the x or y axis. If you want to measure along the Z axis (for instance, the height of a 3D body), how do you do it? I googled "measure the along the Z axis altium", "measure standoff height…

What tool can make a nice 3D image of a via?

I found this graphic somewhere on the web, but now I need to create a similar illustration for some training, but with a 16 layer board having traces coming in on other layers etc. What is the easiest/fastest/cheapest tool to do this? What tool…

How can I securely mount this PCB to a 3D printed case?

This will be mounted to a 3D printed case that will have extra room (2x bigger than this PCB) for other accessories and cables, therefore will need to be secured to the back. I see there are holes, but I'm not sure if those are mounting holes that…

Altium not showing PCB's body in 3D view

I am trying to copy the Arduino schematic, but when laying out my PCB in Altium I have issues with the 3D view. As you can see from the picture below, the PCB appears without problems in the board planning and 2D layout views. In the 3D view, the…

Altium STEP export has missing 3D parts

I'm relatively new with Altium Designer and I'm trying to export a pcb to a STEP model in order to build a chasis in solidworks, but when I export it, there are missing parts. Let the images guide you: The fisrt is from Altium and the second from…

What characteristics for 3D-printed capacitors made of interlacing conductive filament?

There are conductive filament for 3D printers which seem to have between 30 and 115 ohm/centimeter resistance depending on the axis. (Proto-Pasta conductive PLA) They can be 3D printed as a capacitor of 2 cubicly-interlacing-but-not-touching…

Is there a way to use constructive interference to create a specific sound in a specific location?

With 8 speakers, one in each corner, can a combination of waves be emitted that are silent from the sources but form a coherent emission somewhere between? I mean that even if you walked around the room the sound of something, say a ball bouncing,…

When Altium exports a 3D step file, how do I control whether it has separate bodies for each component or not?

I try to share the exporting step file from Altium with our mechanical department (they've already used the NX Siemens CAD tool). When exporting a 3D file from Altium and opening it into NX program, each component creates a 3D step file because of…

Can I find a file of a microchip for a 1:100000+ version on a 3D printing machine?

It would be cool to replicate a semiconductor microchip on a 3D printer, i.e. a C64, an intel processor, an AMD processor. Can you think of a kind of map file format which graphs many transistors and which can sent to a voxel engine or something?

Does alumide provide any electromagnetic shielding?

Alumide is a new 3D printing material that contains aluminium dust. It is mechanically stiffer, but little is said about its conductivity and electromagnetic shielding properties. There is probably not enough of the aluminium dust in it to make it a…

Resistor with first band in color black

I recently bought an Ender 3 3d Printer that comes with a cheap Chinese 24V 15A PSU. Unfortunately, the PSU went dead and by inspecting the board, I found out that two resistors were fried (both the same value). By looking at the resistor’s code…
