Hi gang,

Update, April 4, 2011: Unfortunately, a lot of this thread got lost in the crash. I made another batch of boards, and have plenty left. I usually have a few built up, and if I don't have the one you want, I can build small quantities to order and ship in a few days.

This is the sales thread for the driver I've been building, and has been discussed in the "High Current (SST-90) driver" thread in the Custom & Modified Flashlights > Homemade and Modified Flashlights forum. This is my first attempt at a sales thread, so if I've forgotten or screwed up something, please let me know. PLEASE CHECK THIS POST FOR UPDATES if you are ordering, as I will be updating order status at the end of this post.

For those who haven't been following, this driver is 1" diameter, 5/16 (approx) thick, and has high/low/off modes controlled not by a pushbutton or clicky, but by a toggle switch. By connecting the H terminal to C, you get high, and by connecting L to C you get low. Disconnect both and you have OFF. The driver draws about 0.5 mA in off mode. This could be eliminated by using a double-pole switch.

The high and low settings can be reduced by adding a series resistor in the appropriate control line. This resistor does not carry the LED current, so it can be very small, or even a potentiometer (I've found that 500K linear taper works best, and gives about a 11:1 range of control from the high setting). For those who can solder small surface mount components, you can change the settings by changing on-board resistors.

The IS1006 is offered in the following configurations:

[code]

model Hi (A) low(A)

IS1006-10100 10 10

IS1006-1025 10 2.5

IS1006-0880 8 8

IS1006-0820 8 2

IS1006-0550 5 5

IS1006-0512 5 1.2

[/code]

Other models could be made available on request. There would likely be a small setup fee (new parts and shipping to get them) and some time to acquire the parts. PM me if you need something that's not listed.

PLEASE NOTE: This is a linear driver, not a switchmode driver. What that means is that if the input voltage is much higher than the LED voltage, it will generate a LOT of heat. In most applications it will need to be attached to a large heatsink to prevent overheating. The amount of power dissipated in the driver can be calculated using the following equation:

P = (Vin-Vled) * Iled.

The efficiency of this driver depends entirely on the choice of battery and LED, and the wiring configuration. In the basic configuration, the efficiency can be calculated using the following equation:

Eff = Vled/Vbat

I've written a draft of the data sheet, but I'm not allowed to post attachments, so if you want to see it, PM me your e-mail address and I'll send it to you. I'm still interested in feedback on it if you have something to add.

Note the pictures are of a board that hasn't been cleaned after assembly. I will be cleaning them before shipping any.

3/9/10 edit: I've realized that the H and L terminal markings are reversed on the board. I will swap R5 and R6 values so that the H and L markings will be accurate (H to C as marked on the board gives high current, L to C gives low current).

The price is $25.00 each plus postage, prepaid. I recommend USPS flat-rate box at $4.95 within the US. I can ship UPS or FED-EX if necessary. Shipments outside the US may incur other fees. PM me before ordering if you want it shipped outside the US.

The easiest way for payment is paypal (dlburdette 'at' juno 'dot' com). If you want to pay some other way, let me know. Please put your username in the Paypal notes so I can match up posts with payments. Thanks!

Please check the end of this first post in the thread if you are ordering or waiting for an order. It is regularly updated with order, shipping, and stock status.
