Re: Why is Earth so biologically diverse? Mountains hold the answer

Thanks for the praise from all!.. I will try to post things that I think the members here would enjoy.. I am not a Biological specialist.. My chosen field was Mechanical Engineering, but I take interest in fine instruments, hence my attraction to microscopes and optics..

Re: Compound scope for home education

If a re-seller on Ebay states" I know nothing about microscopes", beware.. There is usually something wrong with it and/or parts missing..

Re: Home made (Very Basic) Microtome

Hello,

This is a good idea.. Where did you come up with your divisions?.. Did you take the pitch of the screw into account?.. The bolt you are using looks fairly coarse.. a finer pitch nut/bolt combination would allow for thinner sections...

Re: Upgrade Olympus BX40 Halogen to LED

"zzffnn, I think that the PWM dimmer has no pot positions, it just changes the duty cycle, not the voltage or current supplied to the LED."

Yes.. That is what PWM stands for.. Pulse Width Modulation.. It changes the amount of duration of the on-off cycle...

"Actually I'm a little inclined to get a bunch of photography gels and make my own filters as Oliver illustrated, that way I can make them lots of different sizes and leave a tab sticking out and not feel like I have wasted a lot of money on filters I don't use." Yes.. The gel filters work very well...
