    Tesla Coil Build Thread

    But changing to the helix would also generate larger sparks in comparison just because of better coupling, right? Something I want to be sure of before I dismantle the pancake coil which took me days of frustration to get right :cryyy: oh well live and learn Yeah, will definitely want to run it...

    Tesla Coil Build Thread

    Hey, could someone give me some advice on my SSTC build? I have a 7 turn primary (pancake coil) made of quarter inch copper tubing and a secondary (2ft, 34awg, 3415 turns). I am currently running it at 12v, which at resonance brings the voltage across the primary much much higher and it can...

    Best earbuds under 20 bucks?

    I personally use MEElectronics earbuds which go for under $20. They are meant for use when doing physical activity so they are durable, and their warranty is a +; have gotten 2 replacements over the course of 4 years from them when an earbud connection gets faulty from abuse (in my case)

    An Apology for Everyone

    :crackup: that is for sellers who actually deliver their products Also the fact that you were using the money you received to 'live' makes you sound extremely irresponsible, almost like a drug addict.... and why would you keep 30% of your money in PayPal? How old are you?

    Tesla Coil Build Thread

    Hey, I finished my SSTC build and have been testing it at 12V. I was wondering if anyone has any experience with arcing at the bottom of the secondary? The bottom of the secondary is only connected to the strike ring. The only arcing I am seeing is from the bottom between the wire connecting...

    Ophir 20C-A-1-Y Modification

    Hey everyone :D Thought I'd share something I did in my spare time. I had always wanted to set up the Ophir head I have nicely in some kind of case or something like that, but as time went on I figured I was too lazy to build a casing to house the components, display and head itself. I figured...

    SOLD: Scientech 365 + 38-0101 Calorimeter LPM

    Here is what I am finding when I look the datasheet up: General characteristics item description: 1.000 in. aperture size; 0.4 to 1.2 microns spectral response; 10uw to 10w power range; max cw power density 30w/cm2; 30 max joules single pulse energy; output (mv/w nominal) 100; o/a dim. 4.000...

    SOLD: Scientech 365 + 38-0101 Calorimeter LPM

    There is no difference from my understanding since they are both using heat as a form of measurment, calorimeter is just the technical term that is used specifically in the Scientech manuals so I thought I'd be consistent in respect to that

    SOLD: Scientech 365 + 38-0101 Calorimeter LPM

    Hey everyone! Up for sale is a Scientech 365 with a 38-0101 Calorimeter (tripod not included) that I thought I would post here before heading over to feebay. I've had it since 2014 but have only used it maybe twice since then (I have a 20C-A-1-Y too) because it is too big for my current space...

    Ophir vs Scientech?

    Hey everyone! Long time no see (school among other things). I was wondering what different people's opinions are on an Ophir 20C-A-1-Y head vs a Scientech 365 with a 380101 calorimeter? I ask because I am currently in possession of both and was hoping to get rid of one, and if you were in my...

    I'm back, and I need help! (Please)

    It should fit into the host if you wire it up nicely (I assume you aren't using a PCB). Use as an example Also, you won't need a host extender if you just use two 18350 batteries. Seeing as how the driver on SL is only 5 bucks, I would say it would be easier to buy the driver from there, but...
