Bit of a change of pace from the electronics, onto the CAD…Here’s a first draft of the first key on the C64 Keyboard – the Left Arrow!
Done at full scale, then at 50% scale
And here’s the cousin, relaxin’ in the sun with the Brim still on, fresh from the printer.
How I got there…………
I’d hoped it would be easy enough to model up a single key, duplicate it 60 odd times, occasionally stretching a few for the larger keys……
That would really make only 4 keys to model –
My very early attempt at extruding a few keys – it just looked odd
So, out with the keyboard, a few macro shots and some eyeballing of angles……..D’oh!
To get the below rough angles, I took some high resolution images, scanned them in and just used Fusion’s canvas feature to create a sketch that roughly made the angles. I’ll print a few out at some point to check
A quick google and I’d found out that this guy – http://www.calaquin.com/search?q=c64 had also figured out the keys were different depending on the row
Thingiverse – https://www.thingiverse.com/thing:2025280 Helped a little, a few others have knocked up some C64 Keys it seems
There’s also some ‘iffy’ looking ones up on the net….
There’s also some amazing models out there
and some good looking ones, but clearly flawed – lacking the curves of the original keys
So, because i’m learning Fusion360 and i’m a stubborn person, i’ll attempt to model one myself!
Here’s my first bit…………
Each Row of keys on the keyboard has a unique shape / profile…This ain’t good for my nerves, I’ve just ‘gotta’ do this properly and that now means I have to model a LOT more keys
The C64 has 3 Main key sizes, Plus a space bar….4 Key types total
- CTRL, Restore, Shift Keys and F Keys are all about 1.5 wide
- Return – About 2 Wide
- Space – About 9 wide and ‘raised’ convex profile, not concave like the other keys
- Standard Keys – 1 wide
Now, I have to model more keys
- Top Row – 2 Key types to model.
- 1 Wide, 16 Keys;
- 1.5 Wide, F1
- 2nd Row – 2 Key types to model
- 1 Wide, 13 Keys,
- 3 keys 1.5 Wide
- 3rd Row – 3 Key types to model
- 1 Wide, 14 Keys,
- 2 Wide, 1 Key
- 1.5 Wide, 1 Key
- 4th Row – 2 Key types to model
- 1 Wide, 13 Keys
- 1.5 Wide, 3 Keys
- 5th Row – Space bar! (1 Key type to model)
Total Key Types to model – 10!
That’s going to be 2 and a half times more work than expected………
