it has adjustable current o/p so perfect for controlling a
LED, you could take off the potentiometer that controls
the current and bring it out to the surface of your
enclosure to a pot with a nice big knob on it ;-)<br>

heard from the space, webcams down so not sure whats going
on tonight, so shall give it a miss.<br>
was called Emyr to see if he was going... his brake lights
have failed on car, so you may/may not see him too.<br>
if Dr Tim is there...say HI TIM... to him for me.<br>
<br>
will try again.<br>
<br>
ps.<br>
Got the sensor kit for 23 from banggood so djd gets his
points or whatever and some other stuff and then used ALi
express for a couple of other things.<br>
it took me about an hour to finalise my order on banggood.
order interface/address very clunky. wouldnt give me a
county, no drop down and wouldnt let me carry on with order
until I selected a county from the drop down it wouldnt show
me! aaargh.<br>
and each refresh meant typing it all in again. oh joy.<br>
<br>
but done now.<br>
<br>
Also.<br>
My cousin just asked me to make a light for his microscope
with variable power with a super bright LED><br>
the flowery shaped affair.<br>
<br>
easy I said! you can use an arduino to play with it and use
pwm to er...umm switch something...erm.<br>
<br>
then I did some googling.<br>
not that straight forward.<br>
<br>
curses.<br>
<br>
any suggestions on where to start? Id like to play with the
arduino and program it...because ive got one. but not sure
what to drive LED with.<br>
<br>
and then maybe use a pic or something. Im open to ideas.<br>
<br>
oh and with that sensor kit.<br>
I noticed that some of the sensors, have a rectangular blue
pot with a tiny 8 leg chip on them.<br>
any idea what that chip would be about and would it make the
sensors voltage specific, ie, 3.3 as opposed to 5v , Pi
/arduino etc?<br>
<br>
ok cheerio<br>

but need to move stuff around to make room.

frick.<br>
<br>
anyone have advice on the old etching thing? quantities of ferous
whateer it was? sourcing it etc.<br>
