By all calculations, the manufactured components should be able to take a little more. You really do want high gain, low Vsat parts that are intended for the current levels you’re running. I know the circuit suggests 2N or 2N mainly because he was looking at only 1 LED maybe a maximum of 3so the current draw isn’t very high. Select a valid country. I’ve been working on a second one, and it doesn’t seem to give very good regulation.

Report item — opens in a new window or tab. I never even checked my figures. First off we need power for the LEDs, that means watts out divided by the efficiency needs to be taken from the battery or in our case single cell.

Modified Item see all. Anyway, I just bought a couple of 2N and 2N transistors. At the kinds of Ic you’re running they’re running out of gain rapidly, keeping them saturating as they heat up you’re on the wrong 2sc25500 of the curve already could be problematical.

Image resizer by SevenSkins. I’ll let you know what I come up with. It appeared to the naked eye that regulation was achieved between 3. And of course, the thickness of the winding wire will help, since thicker wire reduces resistance.

However the power out looks about right. Could be the coil I was using, so I may do a little more playing around with it soon. Delivery options see all. Correct me if I’m wrong.

Low Vsat mean moderate gains, but the Ic is also datasheett low, too low for this purpose. Shop categories Shop home Capacitors Other. Is this suited for the Satcure-type circut?

Another Mod regulated SatCure circuit Sounds like you’re having a grand old time with this. Even though this is a simple circuit in terms of parts count, the demands on the transistor are not at all simple. Mouser Electronics har inaktiverat TLS 1.

This ‘high current, low voltage’ pulse is what “charges the inductor’that is puts the energy into it’s magnetic field, so that when the transistor shuts off again and the field collapses generating current this can be added to the battery voltage in order to get high enough to light the LED. Adding a third winding to the transformer will modify this somewhat, but he basic problem remains the same. The time now is Add to Watch list Watching.

Seller assumes all responsibility for this listing. The flash needs just this sort of transistor to run the converter to raise the few volts in the battery to the hundreds needed by the flash. It’s just the inductor I’m worried about. Terms and conditions of the sale. But the LEDs are datasheeet. FETs can also work, but not in this circuit. Another Mod regulated SatCure circuit Doug, thank you so much for your help. I definitely made a mistake somewhere. With any boost circuit like this, one of datsheet most important components is the transformer.

I’ve found two other transistors which seem to be better suited than the common 2NA and are available from another local non-bulk supplier. But they are not that dim! Probably both is better? Will changing the core material, the wire thickness or the number of turns change the efficiency or output power? It was bright enough to rival the Arc-AAA and had almost as good run time.

That’s where I began. Datasheey just doesn’t seem like a ‘general purpose’ application. I used a 22ohm current limited resistor, which shows 0.

Which is specifically part 1SS,L3M only; any accessories that may be shown will not be included. I’ve made the fix. Yeah, I’m going to have to order a bunch of Zetex parts, a commercial converter, or hack in to a camera. The item is Cat No. Buy 0 Inquiry 0. Another Mod regulated SatCure circuit.
