Automatic power cut off for stove

Jan 24 2012 Published by under Uncategorized

I know this already exists for elderly people and people with bad memory: a timer for the stove.

I think it is a good idea for every household.  Just press a button at the wall and the stove is powered for 1, 2 or 4 hours; should be enough for most cooking.

Never be afraid of having forgotten the stove turned on again.

The power cut off can (of course) be overriden when need arises.

Protection to make your tablet a child’s toy

Jan 13 2012 Published by under Uncategorized

The tablet is a fantastic educational toy with fantastic feedback possibilities but it has two big drawbacks.  One is the “home” button that always works.  It is very good for knowing users but kids are more… experimenting.  The other is the breakability.  A third is the price but I keep that issue out of this idea.

Start the edutainment app of choice and put the tablet in a case with the Home button covered.  The case is padded too to protect the tablet.  I have yet to find a way to protect the very screen.

I almost forgot another threat – saliva.  The cover must cover any hole in the tablet.

The price tag can possibly be remedied by not having a full blown tablet with all the horse powers needed for adult use.  The screen must be responsive but I believe the rest of the tablet can be slightly slow.

A big remote is easier to find than a small one.

A toaster that works as expected

Jan 07 2012 Published by under Uncategorized

There is still to develop a toaster that roasts evenly, toast the first slice as much as the next, roasts the bottom side as much as the top and doesn’t burn the edges.

Let’s start with the even roasting, shouldn’t be too hard. Then take away the need to adjust the roast level between the slices. Continue with not burning the top side while the bottom just ok.  Finally find out how to avoid burnt edges.

Also let’s find out a way to check the bread without having to raise the slice and reset the timer/temp feeler.

Here is a solution with see through sides.

Headset with homing sound

Jan 03 2012 Published by under Uncategorized

Why isn’t there a way to make the bluetooth earplug whistle loudly? It would come in handy every time one misplaces it.
For instance: Start an app on the mobile phone and press a button and the headset makes a sound.

One can also use the strength of the bluetooth signal to at least find out which room(s) it is in.  Maybe one could use a sieve or pan to make the BT signal more directed.

Then evolve this to include glasses, carkeys and whatnot.

Temporary password

Jan 02 2012 Published by under Uncategorized

Say you want to read your email.  But you are at an internet café and the paranoid version of you wonders if there is a keylogger on the machine.

Wouldn’t it be nice to get a temporary password.

Say you use gmail.  So you open your phone.  Surf to and log in as you usually do.  Back you get a temp password that is valid for 1 minute.
Now surf to gmail at the café computer and use your temp password.

A variant of this is to have your tablet at home logging in to your email and then change the password at work. The tablet keeps logging in with the old password and your account gets locked.

This happened to me with my VPN connection and secureid.

Maybe a solution is to have several usr (probably with different pwd) to the same account. For instance a usr for public machines which you can lock without affecting you other pwds you use at work or home.

Quickly log in to your site on another’s computer

Jan 01 2012 Published by under Uncategorized

Say I get an idea I want to publish on my site.  This very site for instance.
Also say I am at a friend’s place and my computer is at home so I have to borrow my friend’s computer.

My password is of course 40 ch4R4ct!ers-long and impossible to remember.  Or at least very hard to remember.  Opening Keepass at my phone and copying character by ch4r4ct!er is boring and error prone.

Wouldn’t it be nice to somehow magically copy the password (or temporary password even) from my phone to his computer.  I haven’t figured out how to connect my phone and his machine and authenticate and authorize and do the copying and all other stuff that is involved but the idea is nice.

This could be taken further.  Why talk about a friend’s machine?  Some work places, typically point of sales, have a card you have to insert into the machine or a magnet to attach to interact with the computer.  I have seen ads for a RFID tag? which you have in your pocket; leave he desk and the computer notices you have left and locks.  One could use the all present mobile phone for the same stunt
