I’ve randomly bought these on eBay.

They are Feuerhand Model 275 Baby Lanterns. They just caught my eye and think they look gorgeous.

Can’t wait to get hold of them to see if I can date them. The glass says ‘Made in W. Germany’ so sometime after 1949.

Three things have come to mind with them:

1. Sympathetic restoration i.e. a bit of a tidy up.
2. Full restoration including a respray.
3. Wire in an LED bulb to combine old with new.

Who knows?!

My partners espresso machine had an electrical fire last month.

Decided to fix it myself and long story short, $65 in parts and a trip to Autozone she has a working espresso machine again.

Makes me wonder if I could help others locally save money by helping them repair things.

Side note I was very happy to see Autozone still has their DEI in place. I checked before going because no company who shuttered DEI is getting a penny from our pockets.

A technical question about SPI. I'm looking at a machine, that has 5 SPI peripherals and a controller. The same CS signal is connected to all of the peripherals.

Am I correct in my thinking that if I would want to reshuffle the devices without access to the firmware in the controller, I'm basically out of luck since it pushes data to all the peripherals with the expectation that the first one takes its piece, forwards the rest to the second and and so forth until everyone has had their share?

Hey hey HEy I spent today designing and laser cutting a box to fit the fan and filters and adapt to my 75mm pipe.

this thing is gonna work super well! Just put together the box and spun up the fan and there’s so much suction.

Now I just have to buy some air filters. It’s designed to take Toyota car cabin air filters, which are super cheap (literally like $10), rectangular, available with activated carbon media, and fit the fan size great.
The filter will just slot right in the top here (will be the side in operation)

Major project today was installing the new hotend assembly on Comrade the 3D printer.

Recently I’ve been wanting to redesign my already custom hotend/direct drive mount as the one I made a few years ago has always been an awkward shape, fitting an extruder assembly that was really designed to be front-mounted, not slung under the X gantry.

I found that someone designed a very cool custom mount for the TwoTrees SP-3/SP-5 series called the Diamond Mount, and decided that it was ideal for my needs. I bought a new hotend with annular ceramic ‘volcano’ heater with integral nozzle thread, which is a very neat recent innovation, with much less mass than a normal volcano hotend block for better thermal performance.

So I spent the last few weeks printing and assembling the bits and pieces. Finally today I did the big job of rewiring everything up to the mount. The odd solder joint, and I added a few heat-shrink labels. Heat-shrink tube transfer labels are so cool.

I ran out of time to really fire things up and work out all the new settings to change for the extruder, hotend thermistor, fans, and work area. Maybe I can do some tomorrow?

Also need to fix up where the wiring goes from the mount to the split sheath. The stock design didn’t have enough space for all the extra wiring for probe, endstop and accelerometer, so I’ll have to modify the design a bit to fit them better.

Ok let’s start off with this weekend. Project #1: design and print some brackets to mount this LED strip light over the bathroom mirror for makeup & skincare.

I CADed it in Fusion as usual — they’re a simple extrusion, just with holes perpendicular to two of the faces. One clearance for a countersunk woodscrew, and one pilot hole for a small self-tapping screw attaching the springy clip for the LED strip.
(Photos to come.)

Sliced and printed 2 pieces in white PETG, in final orientation, to keep the holes round.

I mounted them up on the mirror, then screwed in the LED clips, and clipped in the LED strip.

The 45 degree angle was a good balance for a useful distance lighting the face at our height.

At my previous place I had two strips either side of the mirror for less shadow, but this works just fine.

To do:

  1. replace the overspecced 24V 2A brick PSU with a little wall wart, ideally in white
  2. Somewhere I have a little DC inline PWM dimmer module with a capacitive touch pin — I want to see if I can wire that to the aluminium body of the lamp for touch control. If not, I’ll make a little 3D printed box attached to the side with that touch area.

I’d like to keep better track of all the little projects I work on through the next year. So I’m planning to continue with using #Tinkering but also add #s0Projects and try to remember to throw those on posts about my projects.

I wish there was some kind of post-facto categorisation here. Yes, I know the correct answer is “write a blog”. I need some way to do that with similarly low friction to just posting.

After almost one year in Mastodon, I thought it was time for an #introduction :

My name is Emilio (he/him).

I’m a child of the 80s, but I can’t remember much from that decade —because I was a child. If I had my own theme music, like Peter Griffin, it would definitely be #rock music
(youtu.be/XPM1o9QKw1Q?si=uVM2yy)

At work, I make a living by creating technology #products in the #elearning sector with #moodle 🧡.

Here, I don’t post much, but I do re-toot things I like and support.

My interests are, in no particular order: #technology, #rock, #moodle, #montypython, #scifi, #tinkering, #apple, #gadgets, #fediverse, #edtech, #product, #design, #photography, #coffee, #chiquitodelacalzada

**originally I had planned to strip this down to mount an old treadmill motor on here (spin it and it feeds out 12-24V!), pushing it through a solar regulator to charge up a 12V battery... which could then be used directly to power a ham radio, and or through an inverter to power some kind of A/C equipment. I may still do that. #hamradio #tinkering

Critical Silence

Progress in my latest project using #ESP01 and #HD44780.
I wrote a class that handles texts and its printing to display. I had to test around, since some words (see "Serverkommunikation") are longer than a row of 16 chars. There I just cut off and continue on next row or "page".
After hacking a bit related to umlauts, I now start to design my server, which later receives messages that should be shown.
