ehehe, I have wanted one of these since I was 13 years old… :3

the two cats now high resolution and not on an e paper display!

the left one has shiny whiskers, as if tinned

Not quite ready to show off the current flipdot prototypes, but here’s my first proof-of-concept using Carl Bugeja’s pcb coil :3

boards I designed for an artist ~a year ago, now installed in the garden of a tiny gallery in London c:

a brick wall with small square junction boxes with transparent lids mounted to it - there are 9 of them, led matrix panels inside showing pretty patterns and text the artist designed.

there are some pretty flowering plants in the foreground.

gold star if you can guess what the <thing> I’ve been designing today while waiting for my landlord to show up for an inspection is

a render of a section of curved steel, with a small aluminium part attached. the part has a counterbored torx screw and a small hole below it.

finally found safety glasses I like, and they’re functional / cute enough I don’t feel the need to swap the shields onto a nicer frame just yet :3

I recieved a parcel from a friend with an incredibly important object inside* - my collection of strange nuts grows larger!! :3 *also PCB’s for a project we’ve been working on for ~2 years I guess

an “M0” nut, a hexagonal piece of metal about 4mm thick, and 12mm across the flats.. with no hole or threading in the middle at all

the M0 “nut” sitting inside a massive M56 nut, which is in turn sitting on an even more massive M64 nut

10 months of (sporadic) work turning into an ugly minimum viable prototype that performs better than I could have hoped - such a good feeling :3 #WitchStaff

Weights for Witch Staff machined and bead blasted in my bedroom :3 I’ve been dreaming about manufacturing capability like this forever,,

this is what happens when you let mechanical engineers near ECAD software..

it’s going to be quite a pretty device I think (amusing myself with renders while I’m prepping the silicone mold for the wand head..)

procrastinating building the device by spending half an hour fixing the off-center engraving on the e-stop button? possibly..

a small e-stop button with “STOP” and three concentric arrows - the font is ugly with weird kerning, and the arrows are strange too. it’s also off-center and poorly laser engraved

the same button but with a large crossed out circle neatly engraved to cover the previous engraving

Erin Rose @erinrose.bsky.social · 15/06/2026

am I procrastinating molding the silicone magic wand head by over-engineering the test rig control box? ..maybe, but the aesthetic vibes are very important I feel

an engineer friend of mine who designs press-molds for recycled plastic convinced me to visit their workshop yesterday :3 I got to knead the plastic like dough to make the patterns! so much fun 🧡

a bunch of bright pink / blue / translucent parts in a press mold - they’re about 30mm in diameter and round

the colours swirl together in a pretty way

one of the parts now trimmed out and pressed into a small aluminium tag

I feel like it’s judging me for harvesting components I forgot to add to the lcsc order a few weeks back..

same :3 ..so I gave in and am building a silly little long range 18650 explorer that I've been designing

a tiny little drone which is basically just an 18650 battery holder with propellers (and an HD camera)

It has a cute little heart cutout in the front end of the holder, exposing the battery contact

it’s finally warm weather workshop outfit time again! ..I probably won’t keep the “tail”, I need it for an actual project

me, standing in front of a mirror in red shorts and a sports bra - In the background is my workbench with my laptop and plants.

I have long dark hair tucked behind my shoulders.

a photo of my "tail" - an F-16 ejector seat remove before flight tag, for some reason..
also my butt I guess, it looks pretty nice in the shorts.

friendly creatures (small) 🥺

made a shark holder for my workbench

a long magic arm mounted onto the linear rail with a swiss plate quick release - the linear rail is mounted onto an aluminium extrusion lighting frame. it’s holding a small stuffed shark.

there is a pothos plant in the background, along with two giant nuts, and two crocheted queer bees.

I gave in to an urge to make a vacuum fixture plate and spent ~16 hours machining this on my comically ill-suited plastic framed cnc - it works really well! if only for my health (remembering to eat mid project), I really need a better cnc machine..

a pretty looking aluminium vacuum fixture plate in my hand

it has a rectangular black o-ring indented, and a grid pattern machined inside it with an air hole.

there is a pneumatic fitting at the top, and 4 mounting holes recessed around the edge.

it’s about the size of my palm

I love modifying second hand fabric tool rolls for my own purposes - quite often only a stitch unpicker is required! here’s version 2 of my portable soldering kit

a small fabric tool roll open showing a set of tightly packed electronics tools - in order from left to right:

- solder
- iron tip
- ts21 iron
- metal solder sucker
- small brass wool tip cleaner
- luer lock needle
- glass luer lock syringe of flux
- knipex flush cutters

the roll now folded up, showing a silicone usb-c cable tucked into an external pouch.

in the blurry background a pretty green plant is visible.

successfully smuggled the M64 nut that a cute person gifted me at #39c3 through UK border control :3

a giant M64 nut strapped to the top of a yellow backpack

a eurostar border control prohibited items poster showing red crossed out icons - a gun, a knife, a giant nut, and an aerosol

it has in various languages:
“ATTENTION! if you are found in possession of a weapon (knife, tear gas, pepper spray; etc) during your journey or on your arrival in the United Kingdom, you risk a penalty of imprisonment or a fine.

emergency battery holder! (1 minute of pcb machining, 4 minutes of fiber lasering the steel)

being able to laser cut steel on my desk is so useful.. initial tests tomorrow, if I can figure out the simpleFOC devboard I got :3

the eccentric weight motor assembly now real and assembled - the weight layers are cut from thin mild steel - they are blackened around the edges from being lasered

I finally got a production Tangara! …couldn’t resist swapping in the aluminium back from my prototype unit, but it still feels special I love working on open source hardware with my friends 🧡

a tangara music player held in my hand

it’s got an ipod-1 type chunky industrial aesthetic, with a large capacitive touchwheel

the front case half is translucent polycarbonate, and the rear is silver aluminium - the buttons are gloss black aluminium.

out of focus in the background is my desk plant

Originally intended for this weight adjustment mechanism to be solely for testing, but honestly it might be a pretty neat feature on the final device?

the best thing I ever did for my seasonal depression was mounting a 75W office building LED light bar to a frame on my desk.. (at eye-level so there's no bright spot that triggers my migraines)

the desk (workbench) is pretty large, with an alu extrusion frame on top for lighting, as well as some plants. A laptop and ipad are mounted on a monitor arm.

MGN7 rail looks so cute next to HGR20! 🥺

designed this eurobox racking system ~1 year ago - finally managed to start cnc machining wooden parts for it this month :3

a frame made from 3030 alu extrusion, with wooden ply runners going from front to back

the runners have channels that let euroboxes slide in and out nicely.

the bottom tray is slid out showing a bunch of neatly bundled usb cables.

We made an aluminium Tangara! :3 Bluetooth seems to work fine, even face down on a metal surface (??) We love how it feels!

a Tangara music player with an entirely anodised silver aluminium case, held in my hand.

the case has a slightly rough bead blasted surface, but looks quite pleasing.

the screen is on, showing the device is playing “Equilibrium” by carbon based lifeforms over bluetooth.

in the blurry background of the image is a plant and an air quality monitoring device.

it’s definitely always this tidy c:

the bench has an aluminium extrusion lighting frame built on top, with a monitor arm mounted.

on the workbench is a small chc machine, keyboard, pile of project parts and a blahaj drinking glass.

a drawing tablet is on the monitor arm, with a trans flag themed idc cable design on it.
