Tony - Laser Pointer Warmer

[Ian]

Maplin do a similar thermostat to the one I showed you at DSC but it's a kit. How's your soldering?

[Tony G]

The nearest I got to soldering was walking passed the TA centre in Grove Park,

[Ian]

so what you're saying is, Ian could you pick one up and put it together for me

If so, not a problem mate

Of course, if that's not what you meant, let me know...

[Tony G]

Sorry,

I thought you said soldiering

Tony G

PS Ian, truthfully very, very little experience in soldering.  

[Tony G]

If you could do that, it would be greatly appreciated. Let me know the cost and I'll sort you out.

Thanks again

What's all this about then...? RU planning on wrapping a heater of some description around your laser pointer....

[Ian]

yup, I built a little box of tricks to do just that on a cold night. The one on my side-by-side plate can't easily be put in my pocket.

Tony's gunsight has the same problem.

[Tony G]

John,

At DSC Ian and I were talking about the cold weather and how it affects the laser pointers, as they need time to warm up, and seeing that instead of a finderscope for the WO I have the gun laser fitted, I thought I could do with another gadget, and Ian showed me a mini heater that he made with thermostat and a little, little red light thing, and may I say it looked very professional. The ordinary laser pointers don't have this trouble due to them being kept in the operators pockets and so are constantly warm.
And so this is where this thread has developed from.

I'll have to learn to type quicker as I tend to write a couple of sentences, and someone seems to post the same comments about 10 minutes faster.

[JohnP]

umm.. Interesting - Can you post your design for the heater Ian... Is it using heater tape or regular resistors...

John

[Ian]

From memory, it's a 68ohm 5 watt resistor. I wanted something that would warm the pointer reasonably quickly then switch off, hence the thermostat...

[Mike]

Manufacture them and sell them to Ian King and Bern.

[Ian]

the thought has occurred

[Tony G]

Ian,

If there is any way I can help, just let me know.

Tony G

PS ...........Ian, did you say you needed some armoured flex, or cable????????

[JohnP]

Tony - I still have the roll - if you need it back let me know - I only need to cut a short length off...

Cheers,  John
