The first print in my own 3D printer is on its way! ☺️

and tagged it with Narrating my work ΠiFi Music Player The second attempt at 3D printing a base plate for the πFi went much better but there’s still plenty of room for improvements. Currently I’m testing out sizes for the QR cards and how those sizes effects the necessary distance between the cards and the camera, which in turn effects how large the whole device will need to be. Currently I’m leaning toward a 7,0×8,5 cm large card with a 5,5×5,5 cm QR code centered on the card and this means that the full enclosure doesn’t need to be any bigger in the base than the Pi itself is.
If stand for the QR cards are on top of the USB och Ethernet ports with just a couple of mm of plastic between them, the camera sensor need to be about 55 mm above the surface of the Pi.
If I connect a display to the Pi I can use raspivid to display the output of the camera on that display. The display needs to be connected to the Pi but the command itself can be run either locally on the Pi or remotely via SSH.
For example: raspivid -o video.h264 -t 180000 -w 640 -h 480 will display an image for three minutes, showing the same that the QR Reader script will see.

This morning I drew up a quick 2D sketch in OmniGraffle and then I worked from that one to get the 3D version in Fusion. Hopefully this one will work better. The printer says about six hours to print.

The first print is done but I will need to redo it tomorrow. I forgot that the front mounting holes in the Pi isn’t at the very front so the space between the QR holder and the camera pole is too narrow.

The first prototype of the Pi base plate is in the printer.

and tagged it with 3D printing Narrating my work The Year of Music ΠiFi Music Player I’m changing things up for the πiFi Music Player.
The way I intended to make the πiFi I would need to do most, if not all of these and it just makes it too large of a project. So I’ve scaled it back. At it’s core it is still going to work the same way but instead of having a built in power amp and connecting it to custom built passive speakers I’m going to make a device that gives line level audio out and connect it to a pair of powered speakers that Iris already have but rarely use.
At first I decided to do this using a Raspberry Pi Zero and a JustBook DAC Zero and that was what I sat down to work on tonight. Unfortunately I realised that the Pi Camera Module needs a different cable to be compatible with the Zero and none of my usual suppliers for these kinds of things have that cable in stock. As I was thinking about whether to keep working on other parts of it hit me, why not use the Pi 3 that I used before but without the power amplifier hat? It has a line out built in and works with the camera cable that I have?
So tonight I’ve been working on the first iteration of a simple 3D printed base plate to mount the Pi on, with place to stick the QR codes on in front of it and a mount for the camera. So far the camera mount isn’t finished but I do have a prototype sketch that should work for mounting the Pi and the QR codes. I’ll try to get it printed tomorrow.

I’ve had the MoPho synth for so many years now but I’ve never really felt like I was able to program it the way I wanted. Today however, things sort of clicked for me in a new way. 😊

8 mars, 2021 15:27@MrHenko Is it done? I’d like to have a 3D printer some day, wonder which one you’ve got, and if you’re satisfied with it.

9 mars, 2021 16:12@MrHenko Thanks for your reply. It all looks very interesting to me, but I really shouldn’t get another hobby. Even so, I think there’s a lot of little things that I could fix using such a machine. I’m terrible at 3D construction though, so maybe it’s not for me…

10 mars, 2021 10:00@odd Yeah, that’s how I keep rationalizing the purchase to myself. ”Imagine all the things that I can make that makes life easier.” 😀
But it is a very fun toy to have! And the web is full of free things to print while you build up your own 3D modeling skills.
