I'm willing to bet that I'm the only one whose girlfriend got them a
USBProg for Christmas. ;-)

You may well be right - it only occurred to me this morning that I should
have asked for an Atmel programmer :-)

Very nice. Please report back how you like USBprog if possible.
Thanks.

AVRdragon looks nice and it is supported under Windows/Linux/Freebsd
with avrdude.

Well, the parallel port JTAG cable has worked out pretty well for me so
far, for the ATmega at least.
How long do you think, before the PICs support JTAG? I suppose they
probably wouldn't be called PICs anymore though.

A quick search of http://ww1.microchip.com/downloads/en/DeviceDoc/70165d.pdf seems to show that some dspics already do, the explorer 16 manual also claims that there is a jtag connection from the 4550 to the main pic (though there isn't any software for it yet).

Probably :)

I did get a shiny new Sony K750i (read: neat little uber-customisable
Java-powered {cell|mobile}phone) though. I spent most of the evening flipping
between the UI Theme Creator and GIMP, creating a couple of neat little GUI
themes for it. The defaults are so damn boring...

OK, which one of you geniuses designed the baseball with a built-in
speedometer?  It's cool - has a small LCD display, (an) accelerometer(s)
and reads the speed (using negative acceleration I guess???) when it
hits the glove or wall or whatever.

My favorite gadget is a 18 inch high rocket that uses hydrogen & oxygen
for fuel.  The gases are separated from water by electrolysis in the
launch base for the rocket. The gases are then ignited to
produce...water and F=ma.   Cool stuff - can't wait to shoot it off...

I found some extremely cheap white LED flashlights stuffing my stocking. Turns out they drive the three LEDs in parallel without any form of current control. Not surprisingly, one LED is much brighter than the others.

Looks like I'll have to rewire it so the LEDs are in series and setup a little boost converter to drive it off the three AAA cells.

Anybody have a favorite circuit you'd recommend?

Gaggafle some combinations of

       Dean Wheeler Hydrogen Rocket electrolysis

(Dr Professor ...)

for an electrolysis cell for water rocket design.

He has withdrawn his electrolysis cell details from the net due to the
potential for abuse but will provide them on request to meature enough
sounding enquirers and it's not rocket science (coff coff) to build
your own.

Overdo the electyrolysis and you instead get your own Hydrogen bomb
:-)

It won't work any better a a rocket than an optimised pumped air water
rocket (as one can push ottles close to destruction [or beyond]
already, but it has a certain class to it.  With a little effort one
could make a dual in-rocket electrolysis and igniter head so it could
be primed and then fired remotely.

Roman Black's convertor may do you

http://www.romanblack.com/smps/conv.htm

You'd have to cut it back to 11-ishV for 3 white LEDs

Many established companies make white LED drivers,
for lighting, displays, mobile phones etc

eg Maxim have a new one in just about every newsletter

Yeah this looks a nice phone.

Interesting to know that this is still "new" in UK. It seems to me this
phone is now obsolete in Singapore. Now they are offering K510i/
K610i/K800i. But it seems to me the Walkman phone W810i/850i
and W950i are more popular.

It is 'on the way out', so to speak. Thing is, the Walkman phones are stupidly
expensive (and ugly IMO) and the new K800i is expensive. Plus if it's anything
like the K750i, the firmware is going to be damn unstable for at least another
six months - because the K750i has been out a while, most of the bugs have
been eliminated.

Personally, I'd rather have a reliable not-quite-up-to-date phone than
something that's up-to-date and crashes every day or two. Oh, and it doesn't
force you to up/download stuff via WAP like my old Samsung did (even after I
had it feature-unlocked and SIM-unlocked).

I got an interesting book for Christmas.. "Hacking Roomba".
I've only glanced at it briefly, but it looks to have some
interesting content regarding how to connect my toys to the
Roombas internal network.

My wife has made it clear that she is less interested in a
Roomba, she would much rather have a Scooba. Washing the
kitchen floor doesn't get the attention that it probably
should. :-)

Happy Merry Holiday of your designation,
Lyle

Off the top of my head I'd say look into a 'joule thief' circuit.

You should find plenty of search engine hits on that if you include the
quotes.

Actually I did the same thing, I bought the Nokia 6280 phone for my
wife which is pretty new but "on the way out" in Singapore. If you
come to Singapore, you will be amazed to find that there are so many
mobile phone shops and people changes their phone so frequently.
Not me though, still using either a Nokia 8250 or a 3350. I'd like to
get a smart phone like Blackberry/Palm/PocketPC phone but the
data plan is not so cheap and I really do not use my phone very often.
In fact I am using a prepaid plan and my monthly usage is about
US$4...

However my wife seems to like the Walkman phone more. They
ran out of stock last week. Maybe I will have to buy her a new
phone later if she still does not like the phone after some adjustment.
She is using a Nokia 3120 from her employer and that is a very
basic phone.

Regards,
Xiaofan

I picked up a box of solar-powered LEDs yesterday. Dirt cheap,
some for parts, some for deployment other than garden ornaments.
They work well (a bit of dodgy soldering though). Attached is the
circuit as I figure it, E&OE. The LED brightens as the sunlight fades

Jinx's 1 transistor circuit looks similar to the circuit I elucidated
a year or so ago, no doubt from an identical unit. Alas, they seem to
have settled on a single style of pathlight for the el cheapo Chinese
units on sale everywhere here and the lenses are inferior for my
purposes to several that were on sale up until about a year ago. With
units with clear outer plastic lenses I tear out the internal mottled
diffuser and bend the LED at an angle so it points out one side at an
angle. These then make small spots/pools of light on a path and  a row
of these will actually illuminate a path rather than just lighting up
to tell you that they are OK thanks, but not actually lighting your
way to any useful extent. The current ones have ribbed external
diffusers which scatter the diagonal LED beam excessively. .

The inductors are not, AFAIR, coupled magnetically. This makes it a
nice 1 transistor inverter with the inevitable complexity coming from
the two inductors, at the saving of not having to tap an inductor or
use more than 1 transistor. The Schottky diode makes sense in the
path-light application but costs efficiency. A switch or a FET based
circuit may be better in some applications.

__________________


Attached is "my" 1 inductor 2 transistor LED flasher powered from 1
cell (or more), which also serves as a boost converter. This is the
simplest circuit inductor wise of any I have seen (ie there's only 1
and it's not tapped). I had not seen this circuit elsewhere before I
'designed' it quite some years ago BUT it is based on a very very very
old flasher circuit (I added the inductor) and I would not be
surprised if it was first developed in the 1950s. My 'inevitable
complexity' comes from the two transistors, at the saving of having a
single untapped inductor and very few other parts. As supply voltage
is increased and/or for somewhat better efficiency, adding a few more
resistors can help. eg a resistor from Q2-C to Q1-B is highly
desirable for increased supply voltage. A resistor in series with the
capacitor will alter the discharge characteristics etc.

Depending on time constant this circuit may be either run so slowly
that it functions as a discrete flasher, or at a high enough frequency
that the individual pulses are unseen and the LED becomes apparently
always on.

I looked at your previous schematic for quite a while trying to make it
work in my head...  no luck.  Glad to see it was simply drawn wrong.
Thanks for the update!

Pre christmas madness at the wireless companies here had them
practically giving away SE 810 s and Samsung D807s. Free memory cards too.

Chose the D807 for its HUGE fonts- 50yr_old_eye friendly :)
Do miss the logic of nokia menus tho...
