I have tripods with both 3 segments and 4 segments. A 4-segment tripod has 3 clamps per leg, which means 9 of them to open and close in extending and collapsing the tripod. That's a pain. Enough of one that you sometimes find yourself asking whether a shot is worth setting up the tripod. But even 3 segment tripods are only a bit better.
Ok, this is something I have to believe somebody else has thought of, but I haven't seen it, so I thought I would ask readers if they have, and if not, to put it forward.
Everybody has a socket wrench set. The wrench heads tend to come with a square hole in the top, typically 1/2" or 3/8" square, into which the square drive from the ratchet inserts. There are sometimes spring-locks to keep it in place.
As our devices get more and more complex, configuring them gets harder and harder. And for members of the non-tech-savvy public, close to impossible.
Here's an answer: Develop a simple browser plug-in for all platforms that can connect a USB peripheral to a TCP socket back to the server where the plugin page came from. (This is how flash and Java applets work, in fact this could be added to flash or Java.)
I put pens in my pockets. However, sometimes I put them in without caps, or I put in retractable pens without retracting them to keep the tip inside.
The result, as all who do this know, is from time to time a pen leaks out and ruins a pair of pants, sometimes more than that. It's expensive, and hard to solve. Since the earliest days the badge of the nerd has been the shirt pocket protector, but I put them in my pants. You could try tyvek pocket liners, I suppose, but it's hard to see how to easily add them.
Digital Picture Frames are finally coming down to tolerable prices and decent resolutions. We are about to give my mother one that's 1024x768 and 15" on the diagonal. In part that's because I never got around to building one out of a laptop though I still think a linux distro that turned an old laptop into a digital PF would be a great idea because the ability to do wireless networking to subscribe to flickr and other feeds is the waiting killer app for these frames.
Here's an idea for a way to bring reputation based shopping to the brick and mortar world.
More and more people are walking around Borg-ified with bluetooth earpieces. It's convenient, and a good idea when driving, but otherwise looks goofy and also wears on the ear. I've been a big seeker of headset devices that are wireless, but meant to be only put on while talking, and thus very easy to put on and remove. Self-contained bluetooth devices, with the battery in them, tend to be hard to put on. Nothing I have seen is as easy to put on (or as bulky) as a typical headphone headband.
I get forms to fill out and sign in electronic form all the time now. Often they come as PDFs or word documents, every so often by fax, and more and more rarely on paper. My handwriting is terrible and of course I no longer have a working typewriter. But none of the various tools I have seen for the job have had a nice easy workflow.
Videophones are still an early adopter thing, but I was imagining an interesting application for them -- reunions. Recently a theatre company I was in had a reunion far away, and I couldn't come, but I wanted somebody to bring in a laptop so we could run a SIP or Skype videophone there. It would not have given me a true sense of participation, but individuals I wanted to catch up on could have come to the video phone and chatted.
Most conferencing applications assume there is going to be one big meeting with everybody talking together. That's useful, but I can see a use for something that facilitates a lot of parallel one-on-one or small group conversations, for something like a reunion. In fact, one might be able to do a decent reunion entirely on the internet, or mostly on it.
So many people today are using tags to organize photos and to upload them to sites like flickr for people to search. Most types of tagging are easiest to do on a computer, but certain types of tagging would make sense to add to photos right in the camera, as the photos are taken.
Those who know about my phone startup Voxable will know I have far more ambitious goals regarding presence and telephony, but during my recent hospital stay, I thought of a simple subset idea that could make hospital phone systems much better for the patient, namely a way to easily specifiy whether it's a good time to call the patient or not. Something as simple as a toggle switch on the phone, or with standard phones, a couple of magic extensions they can dial to set whether it's good or not.
Those who travel on trips through many countries face the problem of how to plug in their laptops and gear. Many stores sell collections of adapters, but they are often bulky, and having multiple adapters for multiple gear can be really bulky. (Usually you get one adapter and then use a 3-way splitter or cord for your type of plug.)
Today, however, almost all my travel gear is 2-prong, not 3-prong. It's mostly my laptop and various chargers for cameras, phones etc. And all of it runs on every voltage and hz found in the world.
Everybody who has used a microwave oven has wished at times for a "microwave fridge" that could cool things quickly. Of course the process is very different.
The fastest way to cool things, however, is to get lots of surface contact with a very cold fluid that will absorb and coduct lots of heat. And indeed, drop a drink can into ice-water, which is of course at 0 degrees centigrade (32F) and it will cool reasonably quickly.
We often travel as a couple, and of course both have the same e-mail and web addictions that all of you probably have. Indeed, these days if you don't get to your e-mail and other stuff for a long period, it becomes unmanageable when you return. For this reason, we bring at least one, and often two laptops on trips.
Password security on the web is a troublesome issue. We have hundreds of web accounts, some of them with access to all our money, and it must be secure, not just from phishers and people snooping the web line, but from viruses and keyloggers that can take over our own computers or roaming computers we want to use to access password protected web sites.
The only way to be secure if you can't trust the very computer you're logging in from is to have a security dongle which contains the real secrets and does the logon negotiation, plus confirmation of any big actions like large cash transfers. People have carried login dongles for years, typically which have a screen with a constantly changing number (securid) or which can do challenge/response.
Most of the world is moving now to having a smart phone, in particular one with a standardized data protocol such as bluetooth. I propose a protocol so that web sites can, given a limited channel to the phone, do a login dialog with the phone. The computer would just be a conduit for the data, it would not matter if it were compromised, as the passwords would not be sent in the clear.
The sound of digital pianos continues to improve, and expensive ones also have a good feel, often by building individually weighted keys that go beyond simulating a key on a real piano.
What might be done with more modern technologies, such as super-fast servos, and fluids whose viscoscity can be varied based on the strength of electric or magnetic fields applied to them. (Some of these fluids are being applied to the development of dynamicly responding shock absorbers.)
For many the guest bed has for years been the sofabed. But they are usually terrible beds, with too-thin mattresses that get lumpy. People are moving more towards inflatable beds they put on the floor or a stand. On the floor of course is not comfortable either.
Millions now use PCs for VoIP and online audio chat, and you soon realize the quality is vastly better if everybody uses a headset.
But there's a problem on PCs. If you plug in headphones, it usually disables the regular speakers, often in hardware. So if you leave a headset connected, the system can't play a ring sound when somebody calls you.
Hard disk drives these days are cheap. Too cheap, in that while we love paying 30 cents/GB, the reliability is getting pretty poor. Doing backups, especially automatic backups is a must, but what about RAID?
One of the problems with RAID, at least RAID-5 is that you need to have 3, and ideally 4 or 5 drives in a machine. That's a lot of drives, a lot of power, a lot of heat, a lot of noise. And many machines only have two IDE controllers so they can barely do 3 drives and can't readily do more even if they had the slots and power for them.
So I propose a software RAID-5, done over a LAN with 3 to 5 drives scattered over several machines on the LAN.
Slow as hell, of course, having to read and write your data out over the LAN even at 100mbits. Gigabit would obviously be better. But what is it we have that's taking up all this disk space -- it's video, music and photos. Things which, if just being played back, don't need to be accessed very fast. If you're not editing video or music, in particular, you can handle having it on a very slow device. (Photos are a bigger issue, as they do sometimes need fast access when building thumbnails etc.)
This could even be done among neighbours over 802.11g, with suitable encryption. In theory.
Not that there aren't some major issues to overcome. The machines must be on most of the time. (A single disk can be taken out of a RAID temporarily, and thus a single machine hosting one disk can be turned off or rebooted, but not for long periods.) If you lose access to two disks (or your LAN) you can't get access to the data. And it's going to use a lot of your network capacity, though gigabit networking is starting to get cheap. And the idea gets better...
We hate waiting in line at the cashier and stores don't like paying cashiers so some have self-service cashiers which are still hard to use. So here's an idea.
Provide shoppers who wish to self-serve a scanning wand, which is battery powered and attached by coiled cable to the shopping cart. In the shopping cart, have a number of shopping bags present and numbered. Paper bags which hold a square shape are better. Also have an open area or special bag.
