EDIT: I didn't mention the most important part. The device switches on a ventilator when the absolute moisture content outside is lower than inside a a certain room. This results in drying of the room that you ventilate like a basement with moisture issues. The dew-point acts as a proxy for measuring absolute moisture content.

The file is parametric to some extent and the main footprint is based off of a master sketch. Many parts were imported as step files from grabcad. I used FreeCAD 1.0-rc1 which works like a charm for many things. Next thing I would like to do is to use the new assembly workbench. What do you think?

! Manual "Exploded view",

! Opaque view.

Excellent article about energy efficient farming in colder climates using walls.

Who can suggest an ethical SMTP provider for low volume transactional mail? I'm willing to pay up to 2€/month for a few hundred mails per month.

Have some random images from the Meise (little town next to Brussels in Belgium) botanical gardens. They are specialised in endemic plants but also bananas, coffee and succulents. I also included pictures of the seedbank (the short term, max. 10 years part).

I need a beautiful electric kettle that will last a lifetime. Any recommendations? I'm willing to pay quite a bit.

One of my tomato plants is doing excellent due to the warm weather recently (was planted 2 Weeks earlier).

Also some pics of beans in blossom. They don't seem to be that happy though, any ideas why?

! !

And more tomatos: !

I'm writing a little plotting library for LCDs. I'll try to publish it once it's more polished. What do you think?

For now it supports reading data from a Vector, arbitrary scaling on both axes, linear interpolation, different point styles (square, circle), arbitrary many graphs.

The beans, salads, tomatoes and others are finally growing a bit quicker. With the fourth or fifth start of spring, I hope this time the temperatures keep staying up.

! Tomatoes are still small but growing nicely.

! The new raspberry bushes produce first red fruits.

! Bonus: Happy chicken sharing some leftover melon.

I've used django CMS for a few projects and I'm quite happy with it. I've been wondering what wagtail has to offer that sets it apart from django CMS. I installed it some time ago but didn't dive very deep.

So what are the strengths and weaknesses of both systems?

After a cold and rainy start of spring, finally the beans are sprouting. We also have a bunch of tomatoes and brassicae.

Let's hope the abundant snails don't take too much.

We got a Tetra hen from a friend who can't keep it anymore yesterday. Fortunately we were looking to get a couple of chickens anyways, so we had purchased a used coop some weeks ago.

To our surprise, our cute new chicken, Clémentine gave us an egg already on the first morning. What a nice surprise.

Don't worry, we won't keep it alone for too long, we're looking to get one or two more friends.

From the article

The great promise of Spritely Goblins is to make networking easier and safer. For the past few years, we've focused on developing a toolkit to facilitate this goal. Today, we're proud to announce an incredibly exciting project that will put this toolkit to the test in the largest real-world deployment of Spritely technology so far: a port of the GNU Shepherd system layer to Guile Goblins — the first step in making Guix the object-capability operating system!

Tomatoes, cucumbers, paprika, cannabis, brassicas, etc.

Say hello to my tomatoes, peppers, brassica, cannabis, cucumbers, basil, ... ! ! !

I just got an old Ender 3 for cheap and wanted to replace the crappy extruder with a nicer bowden extruder of my (now) direct drive Kobra Max. When I connect the new stepper, nothing moves. It's a longer stepper and a different manufacturer. Is the wiring different or VREF wrong or are there other reasons why it wouldn't move? The driver is good, since the old stepper is still working.

Thanks for any help!

Hello fellow bike commuters,

I have the impression that my underwear doesn't last as long as it would without me cycling to and from work five times a week. My boxer briefs get holes too quickly between the legs. Since I can't remember a time where I didn't cycle, it's difficult for me to know if this is due to cycling or the normal way for them to die.

Can anyone here tell me about their experience? Is this related to cycling frequently? More importantly, do you know of special cyclist underwear which is not the sporty padded type but something you could wear all day and which would't rip so easily.

Has anyone thought about printing narrower lines in order to get sharper corners? Once Linear advance or Pressure advance is activated, you don't get bulging corners anymore... but can we do better?

Has this been implemented anywhere yet? Does it have a name?

Hey, I've recently designed a Poster about the FHS since I often forget where I should place or find things. Do you have any feedback how to make it better?
