If you are visiting consignment, make sure you check out the beautiful plotter art by @paulrickards

These are such a great example of creative and technically competent application of vintage technology, and great art pieces for your home!

I really liked the 5 1/4 floppies that had been drawn on with the glitter Sharpies. Very clever.

For anyone keeping score, we just published the 50,000th post on @hackaday

I've added a note to the top of the post to mark the occasion. The fact that it's about something as oddball as the right to repair ice cream machines seems particularly on brand for us.

I don't really understand why people use e-ink for their projects when Sharp memory displays are available. Sure, it's only 400x240, but that refresh rate (note that the video is scaled up to show the contrast and refresh rate; it does not do justice to the resolution of this 2.7 inch screen).

The Bad Apple video playing in monochrome on a 2.7 inch display attached to a breadboard and being driven by a much smaller board, maybe an Adafruit Trinket?

@freakazoid
I've used these displays a few times, and honestly struggled to see the appeal. Sure they are fast, but if you're using e-ink for your project, refresh rate is generally the last thing you're worried about anyway.

Though I think the the bigger problem is availability, unless your project happens to need that exact size/resolution of display, you're pretty much out of luck. Whereas I can get e-ink panels in almost any size and shape, some even with one or two additional colors.

@freakazoid
No argument there -- if you need the daylight readability and low power consumption of eink but want something more interactive than an ebook reader, it's a great solution.

I did a hands-on with the SQFMI Beepy a little bit ago that used this display, and it was definitely impressive for terminal use, especially outdoors.

Star Trek: Prodigy feels more Star Wars than Trek at times.

tomnardi,
@tomnardi@hackaday.social avatar

@dgar
I did get that vibe early on, but after a few episodes it started to introduce more Trek lore and felt like things started to come together. Ep 6 (Kobayashi) was a particular standout in the first handful of episodes.

Once it crosses over the mid-season break at episode 10, it really takes off. Ep 13 (All the World's a Stage) is maybe one of the best Trek episodes in years.

Really looking forward to S2. I had my doubts at first (same with Lower Decks), but they've grown on me for sure.

Experimenting with using side-firing 1204 SMD #LEDs to light up #pcbart

The idea is to have a few #sao in this general layout for 2024 so I can swap the logo/text on the front by just replacing the copper/mask layers.

Here you can see the first attempt with the @somafm logo. Needs a diffuser on the back so the light is even. Using clear hot glue now -- works, but messy. Will be experimenting with a printed diffuser soon.

Don't think I ever posted picture of the finished project. Using 3 mm color-change LEDs and a pair of CR2032 cells in parallel which should give decent enough runtime.

This Christmas Eve, there's going to be a 13 year old elf assembling these at the dining room table.

IT GLOWS

Coolest filament yet, but kind of a pain to print with; it’s more brittle and stringy than the PLA I’m used to. But it’s so cool.

The same dinosaur on the print bed, with supports and lots of stringing.
The same dinosaur in the light. It is barely off white.

@tomnardi@hackaday.social avatar

@cassidy
Fair warning, glow in the dark filament is known to be HIGHLY abrasive to brass nozzles. Run a roll of that through, and you can easily find the nozzle has been worn down to the point it's out of spec.

You can get a hardened nozzle if it's the kind of thing you want to print with regularly, otherwise, just keep some brass spares on hand.

Cyberpunk moment of zen: when it's faster (and almost as cheap) to have Amazon Prime send you out complete modules and strip them for their battery clips than it is to put an order for them through DigiKey/Mouser.

Since I've seen other people posting their Supercon SAOs, I suppose it's time to show off mine: the Cyberdeck SAO.

Keeping the specifics a surprise, but pressing the button on the side will cycle through animations that reference various cyberpunk and hacking movies, plus a few other fun things.

Will have 30 of these on hand, trades for other SAOs would be appreciated, but not necessary.

    We're very excited to see what folks do with the badge this year, it's a design that's going to bring some people out of their comfort zone for sure.

    Just opened up the GitHub repo with hardware info, firmware still under active (frantic) development:

    The Gridfinity system looked interesting, but unless I can do the whole thing in OpenSCAD it's just not as interesting to me...

    Luckily there is an OpenSCAD version!

    ➡️ https://github.com/vector76/gridfinity_openscad

    Now I need to decide if I really want to go that route.

    tomnardi,
    @tomnardi@hackaday.social avatar

    @rasterweb
    While the OpenSCAD version definitely seems interesting, I still struggle to see how Gridfinity would benefit me personally as an organizational tool.

    That said, I'm a big fan of the Honeycomb Storage Wall (HSW), and have designed a number of add-ons for it -- and yes -- there are OpenSCAD variants for both the wall grid and attachment points.

    Finally got to use the Carvera for some more advanced PCB milling. So far I think its exceeding the Othermill in performance just alone with the multipoint z probing.
    Those are 0.5mm pitch pads, they are a bit undersized (still learning the ins and outs of Coppercam) but all part legs fit.

    I've been using FlatCAM for isolation routing, haven't heard of CopperCAM before. It is giving you better results?

    The @hackaday Superconference bonus event is GOOOO!

    This is an extra day on the beginning of where a bunch of us degenerates ride the Coast Starlight down to LA instead of flying. I get on in San Jose, but others got on in Oakland, as well as a big group last year who got on in Portland the day before and got an EVEN EXTRA 24 hours of hacking on a train.

    This is an informal event, so you just need to make sure you end up on the right train, which is the southbound arriving at LA Union Station on Thursday night, 11/2. The train arrives in LA around 9-10PM, in time for either a late dinner or going straight to your hotels.

    Last year I recommended business class since that would ensure that we all ended up in the same car and had access to the diner car, but due to current equipment shortages Business Class is unavailable, so I'm getting a coach ticket. We spent essentially the whole day last year hanging out in the lounge car, so coach vs private room class doesn't matter. I'd recommend packing your own meals if you're in coach, since the diner car only offers meals to coach as capacity allows, and none of the food options on the train are very good. I usually pick up a Subway sandwich on the way to the train station.

    Any users using to manage (at least a few of their) packages? Developing on Mac myself and it feels really convenient being able to target both Mac OS and Linux using a single tool, but I have honestly no idea if anyone on Linux is using brew. Are they?

    If not, what would be the best way to distribute CLI tools for Linux? My apps are mostly written in Go, so basically just a binary without dependencies.

    tomnardi,
    @tomnardi@hackaday.social avatar

    @anderseknert
    I've been using desktop Linux full-time for about 20 years, run dozens of distros, and have installed untold hundreds (thousands?) of programs -- and I've never once even seen brew suggested as an option for installing something on Linux. So no, I wouldn't go that route.

    That said, if it was me, I wouldn't go with any kind of package. Just offer a compiled binary. If you want updates, build the capability to self-download the latest GitHub release like yt-dlp does.

    My review of the new WAINLUX K8 is now live on Hackaday.

    Verdict: while a diode laser will always be inherently limited compared to CO2 units like the K40, this turn-key enclosed and ventilated machine is a compelling package for hackers and makers with limited space.

    I've taken apart a lot of stuff over the years, but I think this Epson printer front panel might be the only time I've ever seen reverse mounted SMD LEDs used like this.

    Usually this is the kind of thing you'd see in a hacker conference badge, which is making me wonder who got the idea from who...

    Working on a review for new WAINLUX laser, and part of that is making interesting things that are applicable to the hacker/maker crowd.

    Recently came up this Kerbal-inspired flight sim panel out of black acrylic. Have to say, the capabilities of a small desktop laser (especially one that is designed with some level of safety in mind) are very exciting.

    Full review on Hackaday sometime next week.

    Hey, @hotdogsladies, you might also take a look at Printables.com and Thangs.com for higher-quality models, etc. I personally think Printables is the best maintained and user-friendly site for finding what you’re looking for. Often, people will even upload ready-to-print gcode files so you don’t even have to slice it. Thingiverse is where everyone starts, but it is a bit neglected by its host. Glad to hear you’re having fun printing stuff!

    tomnardi,
    @tomnardi@hackaday.social avatar

    @chrishuck @hotdogsladies
    Got to say, I'm still a little leery of running somebody else's G-code on my machine, but definitely agree that Printables is doing everything right so far -- finally seems like we have a viable alternative to Thingiverse that the community is willing to get behind.
