Fascination: Sketches

Sketches

Here are the scanned documents of sketches when creating the game.
I will have to go through and make an overview level of pics then have the real ones in the build process. This is just for my reference right now.
Also note, there's a Version 2 (crash detection senors) and Version 3 (IR Breakbeam Sensors, currently working on)

Box Frame Designs

4x8' Plywood cut layout.

Have HomeDepot cut 24" (plus blade gap) to make a 2x8 long piece.
Ability to make main box 1.5" wider if needed, going to try 6.5" first.
Also supports inset and outset door.
I was not able to cut a single piece of 3/4" for a solid door, but this will decrease weight.

4x8' Plywood cut steps.

Have HomeDepot cut 24" to make a 2x8 long piece.
Make the next 3 cuts at 34.75", 22.5", 22.5".

If getting the 1/4" plywood, cut out: 24" x 72" and 24" x 22.75". Add to picture later.

Playfield Measurements

Measurement Distance between the supports and layout.

Brainbox Door sketch idea

Probably final measurements. But it a tad smaller for easier opening.

2.5" Spacer Tool

CAD design.

Slicer labeled.

2.5" Spacer Tool, 4" wide

Slicer labeled.

2.5" Spacer Tool, 6" wide, No 1" Spacer Block

This will be used on pieces, like the drop holes supports, where a corner is needed.

Drop Holes Design Sketches

Holes Sketch 2025-12-05

Just holes/border.

Holes Sketch v3 2025-12-10

With sensor cutouts, before wire channeling.

Drop Holes Magnet Locations 2026-01-29

5mm depth cut out for 60x10x3mm magnets.

Hole Depths for Sensor Screws

Different options for depth measuring.

Comparing hole depths for sensors

Test block to see if 12 / 13 mm deep holes will work.

Drop Hole V3 Bottom CAD

Holes_3D v3 2026-01-09

Holes 3D Expanded.
5mm Cut Out
Missing screw hole for #8 x 1 - 1/4" Spax Screws

Drop Holes 3D Sliced

There are two possibilities of slicing, one through the holes and one not. Initial thoughts are slicing through the holes so less warpage, little areas to smooth/clean up.... but not sure, other thoughts are not slicing through the holes so they'll be perfectly round and might be easier to sand the surface. So I'm listing both cutting options below.

Drop Hole Connectors_3D v3 2026-02-22

4.5 holes for Threaded Rod connecting drop holes together.
Place off center of screw holes to not interfere.

Drop Hole Sensors

IR Sensor Case 2025-12-09

Mount for IR Sensor onto the Drop Hole

IR Breakbeam Sensor Case 2026-02-25

Use the 5mm 'base' to sit flush with the top inside the 5mm drop hole depth.

Sensor Case Caps 2025-12-10

Option hold downs for Sensors.

Sensor Cap Single Sided

Connects to a single sensor.

Sensor Cap Double Sided

Connects 2 sensors back to back.

Wire Cap

Still looking into options.

Drop Hole Wiring Center Wires

My first thoughts, need to product test.

Drop Hole Wiring Center Wires All Channels

Option 2, less wires per channel, easier to fix.

Downramp

Currently, the end of the downramp sits on the 7mm Playfield (Floor planking) the slides into the Drop Holes w/ Threaded Rods.
I thought about making the Down ramp go all the way to the cross support and add the ability to put own spacers in, but then it wouldn't slide forward w/ the threaded rods.
So for now, use 7mm thick flooring all the way up to the drop holes.

Downramp v3

Cut in the Center
Choose Dowel 4.5 Width, 25mm depth each side (50mm total)

Downramp v3 Cut

Split into two pieces. Use the Threaded Rod to connect.
