Re: Microprocessor controlled drivers

Uff! i don't know why i cannot see the first and second page of this thread, this is the error:


Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 1083081 bytes)in /var/www/vhosts/candlepowerforums.com/httpdocs
/vb/includes/functions.php on line 4994

Anyone help me for this problem?

I want to make an order but i don't see the new spec of the driver.

Re: FS: Microprocessor controlled drivers **1AA boards available now**

These drivers focus on performance. The PWM frequency is over 5KHz so there's absolutely no noticeable flickering. The microprocessor uses "on" time to control mode switching - if you turn it off within 2 seconds since you turned it on, then it will be in the next mode when you turn it on again. If you leave it on for more than 2 seconds, then the next time you turn it on it will stay in the same mode (last mode memory).

1AA NiMH Now Available

Size: 16x6.5mm (L1P size); Diameter can be trimmed down to 14.5mm
Efficiency: >80%
Full output: 800mA
Reverse polarity won't fry the board nor the LED. But there's a current draw. So if you've just changed battery and find the light not working, turn it off and check the battery polarity.
Price: $10
Modes:
a) 4% - 20% - 100% (no strobe)
b) 4% - 20% - 100% - 10Hz Strobe

Airmail (I can not be responsible for lost mails.)
Canada and US: $3 per order
Other countries: $5 per order
Tracking: please contact me or visit Canada Post website for the cost.

3.7V Li Ion

Size: 18x7mm
Efficiency: ~95%
Full output: 1A until 90% discharge with a typical Cree and 18650; then gradually goes down until 98% discharge, when output will drop below 2mA and the battery voltage is around 3.1V. Safe to use with unprotected batteries. Full output level can be changed by replacing a resistor on the board.
Reverse polarity protection
Price: tbd
Modes:
a) 1% - 7% - 30% - 100% (no strobe)
b) 1% - 7% - 30% - 100% - 10Hz Strobe


-- 1AA Beam Shots ----------------------------
I modified a DX Elite (Elly with Cree) using one of my boards. Here are some comparison beamshots. The Rex2.0 has the whitest tint and the best beam pattern, while both the Elite and the MK2X are yellowish. Probably due to the difference in tints, in the photo the Rex appears brighter but to my eyes it's the contrary. After 10 minutes on high, Rex got hot but the Elite was just warm, supposedly due to its bigger size.

-- 1AA driver beta batch - July 20 --------------------------------------------------------
Some 1AA boards have been assembled. In 100% mode the board outputs 750mA at an efficiency of 81%. If you use a good switch and a Q2 Cree, don't be surprised to see 1A at the LED at 77% efficiency. StefanFS gets more than 1A with a 18650 sized NiMH. It can light up at 0.75V and outputs 70mA at 86% efficiency. With a 2300mAH battery the runtime (to 50%) is about 40 minutes in 100% mode and 4.5 hours in 15%. I believe this driver is taking the power and efficiency of 1AA booster to a new level. Now you get Li Ion performance with NiMH! Vive la NiMH!

Areas to improve: Compensation needed for the nonlinear relation between PWM percentage and actual output percentage (see beamshots below); efficiency in lower modes can be better; the size can be smaller (15x6.5mm). A friend of mine and I are working on these and will come up with an improved version in a couple months. But I'd like to keep this a hobby and thus can't promise a delivery date.

For those who have been waiting and are interested in trying out the current version, I'm offering a limited quantity at $8 each. No more of this version will be made.
Update: The beta batch was sold out on Aug 2.

Can you see it now?

Re: Microprocessor controlled drivers

Will it come with a diagram for wiring?

Re: Microprocessor controlled drivers

Rommul, great problem solving!

Will it come with a diagram for wiring?

The boards come with wires soldered on, as the picture shows. Red to LED+, white to LED-.

Try reducing the number of posts you see on a page in your User CP.. I think that's a problem a lot IIRC. Otherwise, post it in the Questions/Problems forum and hopefully a mod will be able to figure it out.

Re: FS: Microprocessor controlled drivers **1AA boards available now**

It's very nice of you CancerLad. CC fee is not required. But thanks!

ps. the exchange rate between USD and CAD is becoming more and more of an issue.

I know how you feel; have you seen USD vs GBP lately? :sick2:

Anyway, if you need to adjust prices, let us know. I don't mind paying retroactively.

Re: FS: Microprocessor controlled drivers **1AA boards available now**

RV7, please let me know if you need some more to make up for the exchange rate.
Based on you shipping list I'm hoping my order goes next:thumbsup:

Thanks for making these great drivers available to the CPF:twothumbs

Re: FS: Microprocessor controlled drivers **1AA boards available now**

:thanks: Guys you're great. :thumbsup: I can live with the rate now.

Today 1USD = 1.0011CAD. Probably it's time to do a little more shopping in the US - I live just 10 miles from the border after all.

Can you make me some with 100mA maximum current and 20mA medium, 5mA low?

TThanks,
