Not sure I understand the problem fully, but you want a circuit to operate when you push the horn button, without affecting the horn operation.

Chances are the relay coil is drawing to much power.

Have you thought about adding a transistor to your circuit? It would draw very little current from the horn circuit but should allow you to drive something else. - such as your relay. It would of course require you to do some electronics.

Ermmm.... If you use several pins to get the current rating, what happens if one of the pins fails or gets corroded? Won't you risk generating heat? Think I'd prefer nice big connectors for the power and to keep the data lines safely segregated. Depends on your needs and design I suppose.

It's like everything, practice slowly, get good form wired in, then when you write fast for exams your writing will be worse than normal, but still legible.

Practice writing slowly and with good form. Write regularly, give yourself practice pieces. At uni you will be writing FAST, so it'll get worse if you don't keep disciplined.

Alternatively, learn to touch type, and type any work you need to hand in. - if your handwriting is so bad, you may want to make your notes legible to yourself for revision.

Brilliant, many thanks. With all the old phones in my cupboards I'd hoped this was the answer, but it's good to get a second opinion.

 

I want to store a battery powered device long term (decades) as a reference article, it will never be switched on or charged again. The problem is that it contains a small LiPo battery that will be very hard to remove.

Is there likely to be any significant risk I need to worry about? Once depleted will the battery be relatively inert?

This is very interesting. Have you considered studying social engineering? - I've found SE techniques quite understandable to help form a process to deal with people in a 'useful' way. Many years ago I was sent on a positive influencing course via work and discovered that most NTs can be quite easily manipulated with a few simple tricks. In the end I stopped using them as it felt unfair.

Butt your enclosure right up against the lock body, then you reduce shearing forces trying to pull it off the door. Extend the pull bar through your enclosure so you still have a manual override.

While I'm not adverse to home automation, is this something you need in your life, or just want? I like my perimeter security too be simple and tight, extra complications make the security audit much harder.

Will your insurance stand up to home made remote control unlocking?

To answer your question, place the servo in a suitably large enclosure and practically any adhesive should work, e.g. 3mM command strips or even velcro or double sided sticky. When confident that this is what you want, use a screw.

I've avoided the conversation entirely. Ever since the pandemic I've done my own hair with clippers. Made a good enough job of it, even if I've sometimes needed to do a small adjustment the next day.

For a simple style it's not that difficult if you take your time.

Do you on now anyone who uses disposable vapes? There may be a useful battery in one of those if you can't find an alternative.

As a reddit refugee, this is my first post and it's taken a few hours to get to this point. My work involves getting non technical users to use high end tech and agree that language and terminology can make or break a deployment. Reddit is easy, sign in here and away you go, not quite so with Lemmy. I have learned that if a system isn't explained as simply as possible, in terms that your grandmother (or boss) can understand, adoption will be harder.

I'm not saying dumb it down entirely, but nobody cares about servers. Providers may be too abstract. Maybe go as far as calling them 'Homes' - or something else real world tangible. Once a user gets that on board they can then understand that different homes can talk to each other to form a village or community.

I enjoyed the 'thing explainer' books... Cut out all the technical jargon, focus on the user experience and save the detail for those who want to know.

As I say, I'm new here so apologise if I have spoken out of turn out caused offence, I'm watching and learning, and thought my fresh first hand experience may be of use.
