Not childish at all. Remember that inventors have many ideas in their heads, but still go for one or two that seem the most interesting. Write them down though, and if one is good enough... you can even patent them!

Microcontrollers are booming with IoT around the corner. It pays to invert time in them to learn about it. And people that have cross-over skills (knows software and hardware (for example, how to protect a sensor with shrinkwrap so it lasts longer) AND has knowledge of, say, winddirection, so know how to place a box in the shade, away from rain) are valuable.

Also: the same set-up you make for monitoring your bees can be used in a tomato-greenhouse, where humidity (air AND soil) etc need to be measured too... so it pays to understand the full process (where to buy cheap hardware, how to set it up, how to read the data, software) and you can support other farmers. And you either get free tomatoes, or a bit of money for support/maintenance.

And it is not hard. I mean, you can go for the expensive humidity sensor or a very cheap sensor made of mostly recycled stuff.

On this website you learn about using bottles wrapped in white paper to keep the sun and rain out. Low tech does not mean bad tech...

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
