Using your multimeter directly on the output tells you nothing, you need to load the circuit to the same level as an LD. You could try the known dead LD as the load with the miltimeter in series measuring ma.....or you could make a test load for a few cents.... I know which I would do;) Look at...

Sorry I just had to share that... anyhoo, what is it you are trying to do M? Post the circuit, 555s are great chips I have used dozens of them for different devices. Regards rog8811

I just had a wierd moment as I was about to reply to this thread...... Regards rog8811

As has already been said these switches vary a lot, I did this drawing to show how to get the switch on a KD50 to work better..... It may be the same problem with yours, the outer contacts are folded back and are just pressed into the case and when the brass tarnishes you get intermitant...

If you look at other builds you will see that everyone has used 2 supplies, the reason being that the red is case neg, BR can be case pos or neg and the green is case pos. If you are mounting modules to a common aluminium base you may run into problems with supply isolation with one supply...

Did you do any testing before connecting the LD to the driver? It looks like it has a 1ohm test resistor built in that you connect a multimeter onto. The driver appears to have no fixed resistor in series with the pot to stop you winding it up to, in your case, 800ma. Sad to say you have...

Just think, they spent this money suporting inept/corrupt institutions, to put money flow back into the system........ If they had given every tax payer $80,000 would they have put it under the matress? No they would have put it in the bank.... or bought a car...or used it to buy a home. That...

Horizon to horizon cloud expected here with a possible gap on thursday so second year running not much of a chance....but I will be looking. Regards rog8811

To use the above picture as proof of shenanikins you need to know when it was taken, when clearing up the mess it is probable that torches were used to reduce the mass of material for ease of disposal. The front row left hand column looks to me like a typical oxy acetaline cut when the torch is...

Until quite recently london cab drivers had to carry a bale of hay for the horse... Regards rog8811

Yup you can get the host for $31, a few parts rescued from sleds and a couple of hours work will give you a tricolour laser:) It can be done - Low cost yellow pointer Regards rog8811

Not my fastest but the first time I did over 100 miles an hour was as a teen, 3 up in an E type jaguar, I drew the short straw and had to lay on the parcel shelf..... the folly of youth:) Regards rog8811

When I saw the title I thought along the lines of shaving lather:) Just for future referance use the word machinist;) Regards rog8811

TW said it first so I quoted him for ease.:) Ebay has, over the last 2 years made buying and selling far more prone to scams/shill bidding/dishonest listings and so on whilst all the time saying it will be safer. This is just another nail in the coffin, as stated above if I am buying I want to...

Take it apart and you will see a small printed circuit board with a notch at the front, that is where the LD chip is. behind it will be a little square block soldered to the board, that is the limiting resistor. Remove the resistor and solder a pot in its place (somewhere around 500ohm) Set the...

I have hardly been into my workshop since then, I have been too busy with large projects at work that leave me too knackered to think about laser building at the moment. I will return to it when things are quieter. Regards rog8811

I just had to post this one for you all :) Video - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting I have forgotten how to embed, sorry. Regards rog8811

A very nice matched set! You have done a great job with them by the looks, that is a small host to work with :) Regards rog8811

Intrestingly the traffic to my forum has doubled in the last few days, mainly looking at the Laser lighter page :).... In fact I had a look at KK's instructable and see that someone who commented has linked to my site :) Regards rog8811

:D :D And I was gracious enough to say on my website that it was the discussion here that got me thinking.... Laserbee is correct, my designs are out there to be used, I don't do production. Regards rog8811
