Happy 4/20 FC! The ideas and experiences shared on this site are the cornerstone of this endeavor. Before I go any further I want to say: THANK YOU, FC! I would have never found the road I am on without you and the knowledge shared. I am pleased to announce my company: Glass Symphony. The first vape for sale will be called the: Glass Symphony XLR. It is a direct draw convection vape head with an XLR jack for pid controllers. The Glass Symphony XLR 120V is a simple glass vape with a complex air path. It uses precision ground spheres to add surface area around the heater. This gives the vape a large amount of heat and a distributed draw resistance. You can add or remove spheres to change the amount of heat in a draw. The vape can be single hitter power house or a gentle session vape. Tune it to what you like and keep the same comfortable draw speed. Features: - Fast extractions - Adjustable mass - Temperature control - 100% convection on top of the bowl - 100% cleanable 100% glass air path - Filtered intake - User replaceable heater - Works with any 100W pid controller with an XLR (power at pin 1-2). - Parts won’t stick due to thermal expansion (glass expands less than many metals) Parts: The heater is a tried and true industrial cartridge heater. These can be found in some vapes already and a variety of other industries. The sub 100W cartridge for this vape is inside of a glass adapter. The temperature is measured inside the heater’s hot spot. This is great for seeing the max temp of the cartridge and preventing overshoots. Set to 660F, the controller + Glass Symphony XLR was connected to a “killer” watt meter for 12 hours. It calculated the power consumption running 24/7 to be: $30.83 a year, $2.53 a month, or $0.08 a day (@$0.11 /kWh). It took 15 hours to consume 0.49 kWh and that works out to the vape using 0.0326 kW an hour at vaping temps. So 32W is all it needs to create very dense hits. (The vape does pulse at a higher wattage to maintain the temp.) The 3way adapter (body), spheres, handle, and bowl are the rest of the air path. All that can be tossed into a bucket for cleaning (don’t really toss). The whole thing is held together by two stainless steel clamps. So that’s really it! It is meant to be simple, effective, and easy to clean. I’m working on a small batch that will be sold to early adopters who like to mess with pid numbers. My jld612 pid controller uses code “36” to get into the settings. I think that the auto-tuned numbers from this box could be a start for any others that use the same code. tldr; a guy that self medicates with scientific glass is selling the vape he’s been making for the last few years. It will cost $175-275 and be out this summer for pid controllers with XLR jacks. Oh, hey elephant in the room.., Glass breaks. Let’s talk about it. It happens! However, I think this is where this vape shines. I will have very competitively priced parts. But since this is lab glass you have more options. One is your local scientific glass blower – most do repairs for less than the cost of new. Or if you need a bowl or a handle there are off the shelf equivalents that can be found all over the world. So there are many options out there and no plastic along the way. Here's a high temp hit of some purple herb. I'm working on the website now. I can be emailed at firstname.lastname@example.org. More to come!
