Buy an electric hand tool like a grinder. Get a nice, plastic, case.

But the case does not have room for discs.

It is more a rule than extra ordinary that there isn’t room for drills in a case for a drill, discs for a grinders or sand paper for a sander.

The idea is that when a hand tool manufacturer sends along a case with the tool; the case should also be able to hold necessary parts.
It can’t be that hard. I create wooden boxes for my electric hand tools to keep all the extra stuff.

Why is this necessary?

Because children loves to play with batter torches. But they don’t remember to turn them off. And grown ups are not that keen on buying new batteries.

A remedy could be to have rechargeable batteries. But it still means the batteries get discharged, if not worn out, and there has to be an extra pair to swap with.

I it is 2013 and we still don’t know how to attach big files to email.

If you have sold your soul to Google through Gmail you nowadays have a way; but as a free spirit you don’t.

Tired of dirty butter on you picnic?
The butter is half melted, there are bread crumbs (in best cases but quite possible pine needles, regular dirt and possibly caterpillar droppings) mixed in and a spreading knife with butter on the handle. Then there is the lid that happened to be stepped on and then invaded by ants.

Why not have the butter on tube? Either a disposable tube or a reusable one.

To get rid of the knife and all the work to have it clean throughout the picnic, create a small spade on the opening of the tube. This way one presses and spreads at the same time.

All is covered with a hat that closes the opening and covers the spade.

( I have tried having butter in tube; when the temperature is right it works. Other times margarine is better. )

Already today you don’t have to have a SIM card to make emergency calls.

Why not take it all the way and provide emergency phones that does one and one thing only – call an emergency number.

It can be cheaper, more sturdy and have better battery life since it isn’t used much (if at all) and doesn’t have that many buttons, screens, in/outputs and whatnot.

Kids are famous for rising the audio to 11 just for fun.

I am not writing about youngsters and rock but toddlers and kids listening to walkman/mp3-player/whatnot that for a shorter or longer time raises the audio volume to hearing damaging levels.

Why not create headphones that are limited in themselves. Electronics it them limit the amount of energy allowed to push through. Since the mechanics of the ear phones are known it shouldn’t be too difficult.

Sometimes a folder gets filled up with junk. The web browser’s temp and download folder, Visual studios test run results folder etc.

Why not have a service or daemon to surveil this folder and erase old files when it gets over a certain size?

The Visual studio test run results folder could be emptied a day after the test runs (YMMV). The web browser download folder could be set to erase files older than 30 days or so while keeping the large files since they probably took a while to download. The surveilling application could send an email or enter an entry to the event log instead of erasing.

An other use can be for all the log files, one per day, on a web server. Why not send each file to another disc at the end of the day?

I have a Google Nexus 7 stand made of Lego (duplo to be exact). Why isn’t there a site to upload a picture and maybe a construction drawing?

Can this drawing be in a well known, open, format? so it can be used to send as an order to Lego themselves?

And then add 3D printing drawings for even more real word applications – print a brick that fits in an Iphone charging port to make the stand fit better.

As a web developer I am keen on weighing my pages.

Yes I know kb is not a fool proof measurement when there is caching, proxies, DOM rendering and all to make measurements more complex.

Instead of weighing my pages now and then – why not weigh them all the time? Say I have a proxy like Fiddler and there count the kilobytes, number of calls and whatnot to dump into a database. A program then does some calculations and returns a graph and some figures about what it has found. It can either send me an email at noon and an hour before I leave or it can show data continuously like Growl or Miniprofiler.
I believe there has to be some data filtering to erase pages not fully loaded (I develop you know) and loading times of the scale (I develop you know).

I am getting tired of opening favourite editor and navigating to the folder for the hosts file to check it. (as a devops i do this a lot)

Why not have an application that does this and only this? For Windows it should also be easy to restart it as admin to update the hosts file.
