A while back I bought two of those Maclocks with the intention of modding one into a tiny Mac.
-
More #TinyMac progress. Wired up some smol speakers to a smol audio amp.
Designed and printed a volume knob in the style of the original to fit the B50K pot. Biggest issue is how to mount it inside (the amp board has no mounting holes).
The amp turns out to be too noisy, I can hear WiFi and BT traffic. Also draws about 300mA even when the volume knob is switched off.
I think I'll leave it out.
@paulrickards I found exactly the same noise problem with mine. The 3D printer is very nice. I tried filing down the Maclock one to fit in the slot cut in the pot and just wound up snapping it 😔
-
More #TinyMac:
- Swapped in a Raspberry Pi 3A+ for the Pi Zero 2 W. Slightly faster and has 5GHz WiFi which is so much better.
- Mounted the LCD/Pi to the back of the front case with some hot glue.
- Kept the front floppy switch as a power switch when floppy is inserted.
- Installed a LX-2BUPS (2x18650 UPS) inside for power, exposed a USB-C port on the back for charging.
@paulrickards oh, using the floppy switch is a nice touch! Does it do clean shutdown when you eject?

@paulrickards love the mounting behind the screen, too. That’s much neater than having it in the case, which I’d been trying to figure out.

@WiteWulf I can post the STL if you want.
Funny, the noise isn't present until you stuff it all inside the case in close proximity to the antennas 🙃

@WiteWulf Nothing fancy, it just switches the power to the Pi on and off.
I would love to use the touch sensor on the top of the case for a soft shutdown though! Any ideas what's in the top?

@paulrickards no idea; mine’s held in firmly with hot glue. There are scripts available that trigger a clean shutdown when you put a signal on a GPIO pin. I’m sure you could rig the fdd switch to that.

@paulrickards Now you can write a Maclock emulator to run on the emulated one... 😀

@paulrickards
but can you make the toasters leave the left-screen and pick up (exactly) on the right? 🤔
* the first time I saw that was on an attached Two Page Monitor for SE/30 in 1990 ... and I almost fell over because someone else installed it, and the timeout was really long so it had never "kicked in" -

No idea if Basillisk II supports addition displays.

@paulrickards very cute. Almost therapeutic:)

The top of the Maclock includes a touch sensitive area that would turn the backlight on and off, this area marked in red. It doesn’t move, it’s just plastic.
Underneath is a board that is likely difficult to remove, embedded with glue. It has two leads coming off of it.
Without seeing the board, can you theorize how it works and how it could be utilized with a Raspberry Pi GPIO?

@paulrickards Touch sensitive and "two wires" to me smells like it's literally just a bare capacitive sensor, with all the sensing smarts being on whatever it's connected to. (one wire being GND and the other being 'sense')

@paulrickards Capacitive touch sensor ?

@spacehobo @paulrickards but with only two wires to the board that's tricky if it's anything other than just a pair of pads for a touch sensor.

@paulrickards does it just function like a momentary switch, by chance?

@paulrickards if not touch capacitive, could be an IR led & photoresistor in series. The toucher reflects the IR back, reducing the resistance and increasing the circuit's current flow. Not sure if that could be measured over just two wires going to a Pi's GPIO pins. This method of "touch" sensing probably needs more signal processing than capacitive touch, but it's not the worst way to do it

@paulrickards I’m looking forward to my über-portable AIR router project once my Maclock arrives. I also bought a pre-made-but-3D-printed-case mini Mac to maybe shortcut things.
