One Primary To Rule Them All? HANDHELD QCW Tesla Coil Ep5 

Thanks mate. You're absolutely right, I've added a warning in the description. Are there any gloves that would be suitable?

@@HexTheDex Yes and no - with good gloves, you'll find a list of various solvents and their gloves resistance to them given in form of time values called the penetration time - its the amount of time the solvent needs to diffuse through the gloves. With decent standard lab gloves and DCM, you'll often see penetration times around 30 seconds. There are gloves that can withstand for several minutes, half an hour or longer, but in the end, super non-polar stuff just diffuses through every single substance you could make a glove out of. Unfortunately, DCM happens to be carcinogenic as well, which means whatever expensive glove with super high penetration times you buy, you will have to throw them away after contamination. So as someone working with DCM on a regularly basis, my method is just not spilling it on myself. For things like DCM I usually use normal gloves because the thicker stuff ruins my dexterity, and aside from that I just switch them immediately after I get a smear onto my glove. Same with acids and bases btw - imo wearing gloves often even can be worse than wearing no protection at all, because I would notice a drop of sulfuric acid on my skin pretty quickly and could wash it off without it causing any damage, but when I don't notice it because I'm wearing gloves, I can smear it anywhere, including my face if Im not mindful. Things like DCM are a bit different story though. So I really don't have any special recommendation for you, I just wanted you to be aware that these gloves do not protect you properly and to work with the DCM accordingly. They're still better than nothing and the alternatives arent that much better imo

Thank you for taking the time to reply as you have. PPE is last in the hierarchy of control and often taken for granted.​@@covodex516

Thanks mate. Yes plenty more to come :)

Funny seeing people from styrocord here now.

Hello mate. Thank you for this. I agree and have just taken delivery of some new FGA60N65SMDs (some of the last available in the world it seems!) and will be going full bridge. But before that I plan to continue with the IRFP460 half bridge and test the coil with the LabCoatz schematic Staccato DRSSTC, with some rectified 240v mains input. Your advice to master DRSSTC first is excellent, however maybe charging ahead like a fool makes for better youtube?

Thanks mate! Your boost converter idea sounds interesting. Do you know anyone who has documented/implemented it? I'm currently planning to use phase shift for the ramp. I've got a design working in LTSpice but I don't know if it'll work in reality. Would be good to have a backup plan!

@@HexTheDex Interesting approach, I don't think I have seen anyone use phase shift before. Regarding my boost converter idea I don't have a direct documention of someone doing it, but you may be able to regulate the output voltage of your boost converter by adjusting the on-time of it's squarewave. You could start at almost 0% and then ramp it up to 50%. Doing that should ramp up the power and thus also the voltage, assuming that the load on the converter is constant. Alternatively loneoceans has another article on QCW coils (they're first one, the QCW DRSSTC1), which contains even more useful info than they're tinyQCW. There they used an asynchronus buck converter controlled by a microcontroller to generate a ramped bus voltage feeding the DRSSTC. Lot's of useful info there in my opinion. Hope this helps/gives some more inspiration and good luck with your coil:D

It takes all sorts ;)
