bought and picked up a second-hand T460 thinkpad yesterday; did some customisation today

… good thing I already chose ‘spotty’ umm.

anyway, here’s a belated video with a startup beep courtesy of GRUB_INIT_TUNE

My thinkpad turning on, showing the ‘BIOS’ screen, then playing a 994.3Hz POSTing BIOS beep before switching to the GRUB boot menu.

(it’s from this thing. we will be taking it apart before even considering turning it on, and/or replacing the socket+cord combo)

Cardboard box, “Mechanic”-brand “iX5 Ultra”, “universal preheating platform”, 220V.

TIL: 1.27mm hex-head keying exists. This being distinct from 1.3mm.

I have a driver that is, turns out, 1.27mm, and our Tangara screws are currently 1.3mm. I have been gradually fucking up the sockets in the screws with my 1.27mm bit.

1.27mm is... [drum roll] 0.05 inches. FUCKING IMPERIAL DOES IT AGAIN

Side note! 0.05 inches is 50 mil.

This is distinct a unit from "mm" / millimeters (often said here in short-hand as "mils"). Sorry if you just learnt this fact.

@buzzyrobin if I ever become responsible for writing datasheets I'm going to design parts with dimensions like 25.4mil and 50.8mil to really throw people off.

Tangara prototyping! Just churning out some different shapes and detailing to see what feels or looks nicer.

(feat. black tangara stand-in PCBs + displays + touch wheels)

Same, but this time an assembled beige case. The sides pull in little bit down near the touchwheel.

@buzzyrobin @bnys it would be so cool if an australian manufacturer replied to my request for a quote. it would be so cool of them to do that. alas,

@jacqueline @buzzyrobin I might be able to intro you to someone who knows someone if you need machining or molding on the cheap. HMU!

[thinks a bit]
actually I think computers have been shit for a long time, and I much prefer computing of the present.

I think the only reason I enjoy retro tech is that it’s like medieval reenactment; I can have my fun, but then pack my gear and go back to my microcontrollers, a laptop with 3D modelling and video playing, and a desktop PC with a kinda-old VR headset that lets me fucking fly convincingly-real planes. I don’t have to go back to leeches and uploading files via cPanel or whatever.

buzzyrobin,
@buzzyrobin@chaos.social avatar

There’s a bunch of proprietary shit baked into computing these days, and tightening lock-in, but I feel like the possibilities for escaping that are a lot better too.

I mostly think in terms of hardware; computing power (that something like the mnt pocket reform is even possible and hand-assemble-able still makes me :U), storage (I can host jellyfin and a pile of media in a lil box), and connectivity (a friend and I dreamed of a multiplayer x-wing game in primary school; look at XWAU now), …

Further explainers on the MiniBrute replacement cheeks I posted pictures of earlier:

I used a plane to do the sloping nose bit (shaded in pencil, pic 1), then coarse sandpaper on a sanding block at an angle to get a flat surface to use the plane again to make the big 45° chamfer (shaded in pencil, pic 2+3) on that now-smaller nose.

Two blocks side-by-side, now with areas around the front outer corners shaded.
One of the pieces clamped in the work table, with a little 45-degree chamfer sanded out of it (cross-section diagrammed), to rest the plane on to make further, more precise cuts.
The resulting piece, the wood reducing in height from the mid-point forwards, with a triangle chamfer cut out of that shaped area. I put a plane in the background of the photo because I’m a wanker.

buzzyrobin,
@buzzyrobin@chaos.social avatar

I chiseled out the inset rabbet (??? the step the bottom metal panel fits in) first by scoring with a knife (to reduce tear-out), the using a mallet + chisel to take half of the amount out, then half again, then rotating the piece 90° to come at it from the side, then using the (resharpened) chisel directly to clean up the edges, rotating it a couple more times. I’m very new at this kind of thing, and I’m not happy with my edges, but it’s good enough for now.

The rough chunk now removed to show the partially-chiseled area.
More taken out of the channel.
Mostly done. A pile of rough wood shavings next to a stair-step of a cut-in.

buzzyrobin,
@buzzyrobin@chaos.social avatar

Oh! I fucked something up while chiseling. I went too far, and took a chunk out between the front of the piece and the inset cut-out. PVA + clamping sorted it out.

(Then I did it again. Oops. Oh well, I don’t think it’s visible.)

A clearer shot of the same kind of damage, on the other end of the piece this time.
The same area on the finished piece. Seems okay…?
Ditto; the rear this time.

do you like reading a listing full of "the wall plug can break off the main body of the charger exposing the internal wires" and "the power bank may overheat and catch fire" for Comsol and Keji products?

@mcc i think "touching mains wires" is a pretty well-known weakness by this point

@buzzyrobin because of how they process knowledge, the robots don't know that unless they're presented with a great many specific examples of it. honestly they're pretty crummy robots, it's kind of pathetic that they're inevitably going to defeat us

I roughly use "number of browser tabs open" as a lagging indicator for my stress / burnout / how on top of things I am.

uhhhhh okay, so, umm,

update: my mini screen didn’t work for the Debian installer, so I used its TTS mode and stumbled through the install steps (I would anti-recommend doing complicated partitioning schemes this way 😰)

works now

Same, but I’m editing the boot config to add “fbcon=rotate:1” to the linux boot line.
Login screen (for ‘LCARS’) displaying now, in landscape orientation.

finally got the m625q out of the box, and even though I’ve seen one irl it still strikes me how comically teeny they are. just look at it!

(mouse and my ramshackle prototype tangara for scale)

buzzyrobin,
@buzzyrobin@chaos.social avatar

One downside: I went to test my little HDMI screen, but the M625q is 'only' DisplayPort; guess someone didn't wanna pay the licence fee. 💁‍♀️

Serious question: the port is marked as DP++, but I can find nothing that'll tell me what version of DisplayPort this is (an accordingly whether I need to buy an active DP-to-HDMI adapter or if I can get away with a passive one). The box is an M625q 10UY ThinkCentre. Uh. Help? 😅

@buzzyrobin
this is why I'm super annoyed that my laptop only has a single HDMI out, and not a single DP out

and I know that the igpu has a dp and two hdmi outs because it shows up under linux sysfs

they just didn't wire it up on the motherboard 😭

@gsuberland @buzzyrobin I thought there was something about Autodesk and being sued or threatened by regulators about their subscription policies.
It was Adobe:
