Today (2018-04-27) I found these tips on Twitter by @heydebigale, they seem like a good collection:

• Keep color schemes simple. Try to stick to no more than 3 colors beyond black & white.
  • If using 3 colors, try using the 60/30/10 rule for percentages of use of each color. This will allow color to emphasize.
• Consider using contrasting colors to emphasize difference & harmonious colors to illustrate unifying concepts.
• Consider color vision deficiency. Use different value (not just hue) to be sure that your text is easy to read.
• Never use color alone to convey your meaning.
• For screen layout, use the rule of thirds.
  • Split the screen into a 3×3 grid.
  • Important elements should be placed at 1 or more of intersecting points.
• Always create a strong focal point.
• Avoid holes in layout and move white space to the outside boarder.
  • LESS IS MORE.
• When considering typography and text, use text size for hierarchy/importance.
  • Avoid using more than three font sizes.
• Text should not be more than about 1/4 to 1/3 of the real estate on the screen.

Another couple of interesting rules:

• Mayer’s Multimedia Principle: people learn better from words paired with pictures than words alone.
• Mayer’s Modality Principle: People learn better from graphics with narrations than from graphics with on screen text.

In my day job I need to do a lot of testing during hardware development.

Over the years we developed an in my opinion quite good template for our test reports.

I simplified it to simple text format just to provide the structure and required information. Design is up to you and your corporate needs such as header, footline corporation logo, font and so on.

So, if you also feel the need to have a structured document for your hardware test reports, here you go:

I own an older head-lamp (one that has a rubber band which you wear on your head) that still operated with a light bulb.

But LED technology has made impressive progress in recent years and therefore I had the idea to transform this lamp to a LED light source.

For fast prototyping or small circuits strip grid PCBs are ideal.

The components are fast placed, the connections/routes in the one direction are yet there. One only needs to place the wire jumpers or sometimes needs to cut a PCB route.
