Aerospace engineer, maker and terrible amateur programmer. I will probably toot when I've made something, mainly 3d printing and plotting; if you want to make what I've made you'll probably find it on Printables: https://www.printables.com/social/152251-pittance/models

I am also on Pixelfed: https://pixey.org/fastness

The first PCBs that I've designed has arrived :)

I've been running my #penplotter with a high voltage brushless servo for a while but it was connected with an awful hacked-together nest of wires, perfboard and iffy sockets. This should both be better for me and be easier to share with anyone else who wants one

I designed it in KiCad (which took a while because I have no idea what I'm doing) and I ended up using PCBWay: with their $5 promotional coupon the boards were ~free, $5 delivery

I do not want a meat tea bag

Thanks for clearing up that worry for me, PG Tips

Parsnip found a sunbeam #caturday

Maybe it's working after all?

#penplotter

Trying some new plausibly CMYK pens in a halftone plot. Before where I've found the right colours the pens have had very large tips so they're not good for detail. These (Staedtler ball 4320, 10 pack assorted colours) are ballpoints so perhaps the better detail might compensate for the probably worse colour matching?

We (youngest and I) tried making macarons

We used every utensil in the house but it appears we've achieved macaron

Experimental 4 Colour CMYK plot with each colour being built with a different conversion technique:

Yellow: fast marching method contours
Cyan: strips where lines bunch up in darker areas
Magenta: halftone dots made from spirals
Black: large spirals where multiple lines spread apart for darker areas

The pens are random fibre tip markers I found, they worked ok but the colours aren't really right. Also the pen shifted on yellow so there's a bit without enough colour

KLM have ensured that this trip to Montréal is the gift that keeps on giving: my flight to Schiphol today got cancelled so now I have to go to Paris then Amsterdam tomorrow. In the meantime I'm in a totally generic airport hotel armed with meal vouchers

But: I got my bag back! That means I didn't lose the lovely hand knit woolen socks I had brought to deal with the temperature

This was a very boring post so here's a lovely photo of Montréal by way of apology

So I'm in Montréal this week for a work thing and it's amazing. I'm in the ICAO building and it's got lots of fascinating art everywhere. It has also been the coldest place I ever went to, -22degC over last weekend

However I made the mistake of flying KLM and, since Friday, they have still not got my bag to me and haven't really offered any help or information - their website doesn't even say where my bag actually is. How can people who make it so hard to contact them also have awful websites?
