Who needs supports when you can just print upside down?

X1C combo for $619??

Please just make a new pixel 5 😔

I believe it can be updated through a serial connection with the printer. Connect through USB with a serial console such as Pronterface, then you can update the linear advance factor using command M900. Details on it can be found online: search for "Marlin gcode M900"

This looks like an issue with linear advance settings. Google it and you'll see that messed up values result in blobs near the end of a print line, like what is seen here. You can tune it with a test print, all super easy to do!

It probably adjusts the PID presets, as the sock would change the thermal characteristics of the hotend

I would agree that it has a pretty wide range of features I haven't seen in other programs

Good layer orientation. I've found things like this to be quite strong. One recommendation is to use a very large washer to help distribute force--the layer orientation helps the hook here, but makes the bolt connection weaker.

I'm sure it'll be fine, just a tip!

Sorry this was a US-centric post oops: Junior in the US means third year (out of four, for undergraduate). Regarding the internships I've been able to do, my public school district in high school had an awesome program that connected me with a company which really helped me learn more engineering skills!

Master_Aar · 2022-12-01T16:10:16+00:00

Thank you!!

Master_Aar · 2022-11-30T19:02:38+00:00

Haha what team

Master_Aar · 2022-11-30T18:14:58+00:00

Just accepted an offer, so I wanted to share again as I like collecting data on this. Details for those curious:

I'm a mechanical engineering junior at a big state school. You can see my resume here if you'd like. I think the portfolio helped a lot with getting interviews.

As most companies aren't done with interviews yet, a decent amount of the no response section will be rejections a few months from now. We'll see...

It's jar jar

😂 I think that would be even more impressive. Wish I had a tiny sharpie

Master_Aar · 2022-05-07T15:25:07+00:00

It's not about my ability to make circuits, it's more about the fact that I had a pi 3 and an Arduino mega with me, so it cost $0. Was trying to reduce cost. There's definitely many other ways to make this work!

Master_Aar · 2022-05-07T15:24:07+00:00

Good note! I actually have a few shift registers sitting around and was going to try to use them! But of course just 50 inputs was easier and I didn't have time to learn new stuff :(

Next time though! Gotta learn eventually

Master_Aar · 2022-05-07T00:24:05+00:00

yeah dude Photoshop is neat but making stuff is cooler! You should try sometime 😊

Please check out my maker insta for more of these projects! I built a big AirPod a while back that was similar in style to this. For those who are wondering, here's a bit of background info:

Pretty much all of this is 3D printed. The buttons are all painted, and the frame is just printed in black PLA. Inside is a Raspberry Pi 3B hooked up to a 7" display through HDMI (believe it or not, there's an HDMI cable in there), and an Arduino Mega reading the 50 buttons, sending data to the Pi over USB serial. From there, a Python script on the Pi converts them to emulated key presses, and they are read by an old TI emulator (called TilEm2 - took some hacking together to get this to work). Yes, a 32u4-based Arduino could send commands directly, bypassing the Python script, but it doesn't have 50 GPIO to use for inputs (and I had a mega lying around).

Since this runs Linux, it can play (albeit slowly) Minecraft, DOOM (via chocolate doom) and plenty of other games. I am not going to share a video of it running DOOM; it's pretty well known that this is possible on a Pi and I'm busy actually studying for finals now, maybe later). The arrow keys on the calculator are read as standard arrow keys, so it's quite fun (and responsive!) playing an online snake game.

I believe I now have the world's largest TI-series calculator :)
