(I am not necessarily interested but I guess many on here would help with your ideas.)
It depends on what you mean by
technical stuff ?
1) Have you a specific idea in mind?
2) Does it include shell scripting, (or other coding languages)?
3) Are you biased towards a known start like Arduino or Paspberry Pi?
4) Over what time period are you looking at for any specific type of project?
5) What age group are you aiming your ideas at?
6) What limitations are you putting on said project(s), e.g. cost, complexity, tools etc?
7) What are you thinking of at this point in time?
8) If no hardware is needed what are your ideas for SW apps'?
9) More I can't think of at the moment...
