App for finding sports mates for friendly match in the vicinity

Feb 05 2017

What if you have an area suitable for football in the vicinity but not enough friends to play?

Why not have an app where you describe the lawn and level of seriousness to let others join?

Or say you have a team of 6 but want another 6 to play with?

Or you want to play some sports but don’t know where people are playing?

There should be an app for that.

Enter location, time andlevel of seriousness in an app. Other interested in the same area; who feel like playing, get a popup and you all get together and play.

The idea could be extended to the drummer calling in sick at last minute, garage sales, apple picking, sailing crew, swimming company or shopping company.

A shopping app that adapts to your behaviour

Nov 05 2016

Most shopping apps are a list of text. They typically contain some aids for easily writing gherkin, and cantaloupe and how many but they are still a list from top to bottom.

Most grocery stores have vegetables in a part of the store so when you pick the tomatoes you probably want the corn and the apples at the same time; but not the milk, chocolate or spices.

So I suggest the list reorders itself when you start picking to show what’s nearby.

One can also use the localisation features of the phone to find out which store you are in and adapt even more as it then can know whether bread is in the start of the store or later.

Painting by numbers and jigsaw puzzle in one

Nov 05 2016

Why not mix painting by numbers and jigsaw puzzles?

One can either choose to paint each piece by itself or puzzle it all together and paint it afterwards.

Fast and simple chat

May 27 2015

Say you (involuntary) started an SMS or email avalanche with some friends. Why not have a site with a very simple chat. No usr/pwd and no functionality; if you know the URL you can get to participate.

The chat is erased after a few days.

But in that time the participants have sorted out where to meet and who brings what and the SMSes/email flood can trickle down to a more manageable level.

“hey everyone – information overlaod – please continue the discussion on”

The GUI code is reduced to as few bytes as possible to load blazingly fast on mobile devices.

Send clipboard to/from mobile/computer

Feb 11 2015

Say you get an SMS with some information you want to email togther with some information on your computer.
Today you copy the SMS text into an email which you send to yourself. You open the mail on your computer and fusion it with the other information. Finally you create a new email and press send.

Why do the intermediate email? Instead send the clipboard directly to the computer. And vice verse.

Square or angled stackable blocks

Jan 13 2015

Having a square, being it a try square, a carpenter’s square, a mechanics square, a speed ruler, combination square or whatever is necessary but often not enough. A big square is good for measuring big things like walls but more or less totally useless for dove tails and vice verse. There is also the problem with not begin able to use a square since the very corner is protruding or misshaped in a  way.

So why not have square blocks to stack and clamp to each other. Make them non magnetic to not gather metal dust. Make holes in them to make it possible to clamp them together in various shapes. Make room for magnets to put in an take out to stack them. Make the surfaces so even that they stick like Johanssons måttbitar. Make other angles and radiuses.

An application or device for measuring interruptions per hour

Sep 22 2014

There is some talk now about how much an interruption in the work flow costs when you are, for example, a programmer.

Why not measure it?

Say one sits by one’s computer. One can then have an application with 1 button on it which says “I was interrupted”. This application then tracks the time of every interruption and creates some output like a diagram or some statistics.

Since it is to cumbersome to activate a program to press a button one for instance use AutoHotkey and map a never used key combination or maybe the scroll lock key to press said button.

If one is moving the cellular is oft kept within reach so have an app that reacts on a simple drum solo or morse presses. (one could of course have an ordinary app but since it too much job to grab the phone in the pocket, unlock it, find an application, activate it and then press a button, a simpler user interaction should be used)

Create a router plane from a chisel

Sep 15 2014

This is already done by creating a hole in a board and then jam a chisel in this hole; but it is a clumsy and imprecise.

There are also already perfectly good router planes but they are expensive and have only one cutter and hence only one width.

But… as a carpenter one has a bunch of chisels. So why not have a holder for them that does what a router plane does? It is probably not as good as there isn’t any flat part of the cutter against the wood but for much of the work it should do.

Take this idea further to a rebate or shoulder plane.

Let the hot stove shine red

Aug 12 2014


One cannot see on a stove’s hot parts they are hot; in best cases there is a red dot somewhere else to show the burners are hot.

Possible solution(s):

If a red light cannot be mounted into the very burner, being it metal, glass or any material, have a pin spot mounted in the fan shine a red light on the burner.

Buildable boxes

Jun 24 2014

I like to put many of my things in boxes.
For my tools I build special purpose boxes, typically out of plywood. It takes time.

Why not have box building pieces like lego, meccano and fischertechnik but more sturdy?

Say the pieces are built of 100mm x 100mm pieces. Then one could build a box in any multiple of 100mm size.
The best would be if the pieces weren’t glued together so when your box is too small, too big or your tool is broken and no longer needs a box – just rebuild.
Still, having a bunch of cheap pieces to just build a glued box is better than having no pieces.

One idea

Build the boxes like log house. The “logs” could be “small planks” with already made corners to fit to each other, like the log houses have, but more relying on fastening and less on timber weight.
The corners could snap together or be fastened with a rod going through or an outside fitting corner piece.

I am not necessarily thinking of only wood as material here; plastic or metal or sturdy paper would be just as fine, possibly even better with mixed material.

Another idea

The construction could be more like ordinary plywood boxes with metal edging but as DIY. The edging is easy – buy it in 500mm lengths and cut as needed. The plywood can be considered easy too, just buy a 2 square meter piece; but that only works if one has plenty of storage space. Instead have them 500mm long and 50 mm high; cut them as needed and fit together with metal edging and some sort of metal not-edging.

Yet another idea

One could get away with less tools if the pieces came in 100mm x 100mm pieces with fasteners already attached. Say continuous casted aluminium profiles made to fit each other with or without a third piece. Just join the pieces and have a box. This idea looks like it would possible to pick apart and rebuild too.


I found the OS project that solves many of the question regarding dimensions.

At Low tech magazine is an article that talks about modularity and reuse.
