Rick,

You posted an answer to a question that was asked a few years ago. The question was about how to measure the inductance of a coil at home. You said that the easiest way was to " Place a capacitor of known value in parallel with the Inductor and apply a voltage of known frequency to the setup; vary the frequency and to determine when resonance occurs".

My question is: is there a way to determine the resonant point, without using an Oscilloscope.

Hi I was reading some of your comments in an old article on using no. 6 plastics and was wondering if you might know if gift cards can be used. The number of the plastic is not listed on the cards. My children have stacks of these and they have illustrations on them that are very cute like squirrels and transformers and even their favorite TV characters. I thought it would be neat if I could somehow shrink them a bit for necklaces or just melt them a tad for key chains etc. Any help would be great. Thanks :)
Hi. Thanks for helping me with that question, I chose it as best answer. I will hopefully take your advice and move on! :) Have a great life while it lasts
:-) Thanks, I always enjoy myself - made it a rule when I was very young.

Life is not a rehearsal! so make the best of every day!.

Hey rickharris, I was wondering if you had any tips or could provide any information on cutting acrylic. Your idea for the mood light is awesome and I want to try it, but I haven't the first clue on how to (besides scoring with a utility knife over and over again) best cut acrylic. Thanks, Adam

I cut it with a band saw but any saw that will cut wood or metal would do - and a bit of arm effort.

Hi Rick, If you fancy doing some more LED mods let me know and I'll do you a deal on the LEDs. I'm already a fair bit cheaper than your current supplier! Ben
