Also similar: Join a local Toastmasters group. This is a global organization where you learn and practice to speak in front of a group, both prepared speeches and spontaneous. It may find weird to join it, but I would advice to visit one once in your neighborhood: They are all super friendly and I have seen dozens of people come in and move from shy and awkward to great storytellers in just a year or so.

I live in The Netherlands (actually in the same city as the photo's were taken): There is a very large difference in traffic density and complexity between the larger cities such as Amsterdam, Rotterdam, The Hague, Utrecht and the rest of the country (including middle sized cities).

When I visit one of those larger cities, I am also constantly looking for bikes everywhere not to be crashing into me.

Nice, these are located less than a mile from my home and nicely situated along a stream, just like a bunch of mushrooms in a forest.

They have been around for decades and were an innovation project from an alternative living cooperation in the city (Den Bosch).

I think they are now mostly occupied by students and 30-.

Author here. Thanks for all the great and different insights and experiences. Especially also about 'feeling being listened to'.

To be fair, I was a bit short in my description: I do have a great relationship with my manager and he is one of the best managers I ever had. Also, I am not a developer, but a product manager, so already used to steering the 'ship'. We are in a relatively small team of 6 and we are all sitting together (including manager).

CTOUCH | Senior Backend Developer | Eindhoven, The Netherlands | ONSITE (hybrid)

At CTOUCH we develop large-format, Android-based touchscreens for education and business up to 86". We have been operating for seven years, are about 80 people and have been profitable for a long time.

We are looking for a senior (backend) developer to head our growing development team of frontend, backend and Android developers.

I like what Steven Covey writes: "Love is a verb".

I find that both my wife and myself, and myself and my kids get closer by doing things together that we all enjoy. This ranges from trying out a new restaurant in town, to going to a museum or themepark we all enjoy, to going on holidays.

What I am trying to say is that experiencing things together may help you bond more and experience pleasant feelings together.

In my family and friends group, friendships and partners can often orthogonal: You do different things with different people and they add to life experience, not substract.

I can imagine that if you state to your partner that they are number two and always will stay, it might already put a strain on the relationship: In a sense a self-fulfilling prophecy.

For these simple designs (and more complicated ones), my experience shows me that the problem has been solved with Eagle and a decent design rule file. I have autorouted tens of 2-layer designs with between 5 and 200 components with Eagle's autorouter and the seeedstudio .drc file as constraints. It's good and quick, give it a try (would take a few sec <50 parts, couple of minutes > 100parts)!

BTW nobody professional uses curved traces (except very rare cases), have a look at any electronics PCB

It is certainly true that you can spend this amount of money on a product and not make money on the first 5000 product run.

But it is certainly possible to make money on such a first batch: Why do you need inhouse EE, ME, DE en Embedded Engeneer for a headphone. Many of these functions can be done by a small design firm or freelancer that you hire for a much smaller fee. In addition, these people do this all the time for different companies and have a huge experience this way and good contats (you can also go with teh bigger firms, but then you probably need the same amount of money).

The standard bootloader needs a resonator or crystal to run the oscillator. You can also program a bootloader which uses the internal oscillator in the Arduino IDE, in that case no resonator or crystal is used, like I did with the attiny.

Thanks for the nice comment.

To answer your question: 1) Yes, they do. But by measuring the moisture in the soil, you will get an alarm when a certain amount of water is extracted from the soil, being caused by heat, sun or a thirsty plant. After quite a bit of experimentation, we found a threshold value that works for most plants. Not cactuses ;) 2) Indeed we check more often than needed. But if the plant is getting dry, we want to briefly signal every five minutes and before we do that, we do a quick soil check.

Thanks for your reply.

The resonator is shown in the 'Eagle schematic', right in the middle of the picture. The first schematic is just for the moisture sensor. I used it as a crystal to run the ATMEGA.

When the battery is gone, you just pop open the enclosure and put in a new CR2032 coin cell battery. You can get those at every gas station or supermarket.
