How to build a versatile and compact 9v LED lamp

9v LED lamp
P.O. got so excited by all the responses from the TicTac flashlight project that he sent us another of his creations.
This time it’s a LED lamp created from the scraps of an old 9v battery and three LED’s. No need to use a resistor here as he’s used three 3.5v LED’s which adds up to a required voltage of 10.5v… which the battery can’t supply.
The benefit of this is that you don’t have any losses in a resistor and the battery will end up lasting longer – but the LED’s will not operate on 100%.

Take it or leave it, this is a great project that involves few components and has a compact and robust design.

TicTac flashlight

TicTac flashlight
P.O. sent us this how-to on building a very handy flashlight out of a old TicTac mint box. It consists of a empty TicTac box (duh!), three batteries (that fits perfect), a small switch, a resistor and a bright LED.
It might not take a rocket scientist to figure out how to connect it all, but still…

Grynx in the slow lane…

…but no way we’re gone in any sense.

Status I managed to get myself a new job far far away from home and with working long hours and spending a lot of time on the road I really haven’t had that much time for my baby (Grynx that is) in the last month. It’s really unwillingly, I promise! There’s nothing better then to have crazy idea, realize it, publish it and reading your comments about it.
So okay, I haven’t been posting that much lately but that doesn’t mean I’ve giving in. No way José!

Forum Some of you have notice that little G in the right hand side navigation. Most haven’t. That’s the link to our community, or forum if you’d rather call it that, where it’s a bit easier to discuss things then in the comments area on these pages.
I’ve added an area there called Hatching ideas which is really a good area for brainstorming, something that I’ve actually missed myself.
There are more areas there but I take it that this one is the most interesting one in the long run.


Ongoing projects I have two project in the pipeline right now and we’ll have to see when I can complete these. One is a non-electric cool iPAQ accessories and the other is a interesting LED dingy (as everyone else are building LED things now) which based on some LED’s I bought
from China recently.

HELP I don’t want Grynx to stagnate! We have between 80-120.000 unique visitors and we’re serving aroung 300-500.000 pages every month. Never though that when we started a year ago.
But with my limited time right now I need your help more then ever. You can send me link tips if they’re good and related to what we do here, or whole projects. What to be part of The contact information is in the right hand top of all pages.

I’d also like to say thanks to all the people keeping the discussions alive on Especially the ones on the VoIP related pages as the Siemens Skype, Build your own chat cord, and Simple Skype VoIP analogue adapter.
