Any updates? It's like an electric version of the Vaponic vape design, seen a good DIY thread on cloning that one, but not using electric heating and temp control. Great craftsmanship and engineering! :clap::clap:

I working on my own vape that is similar to this in how it works fundamentally. The central piece I'm using is a glass one-hitter or Arizer stem, so its more suited to upsidown use, while the BudToaster looks great for upright use.

Have you thought to use something to thermally couple the coil to the glass tube? It could greatly increase the energy efficiency and heat up time, insulation like ceramic fibre wool could also be good, and can be used in combination. For thermal coupling I have been experimenting with fire cement, but my tubes have been cracking, might apply a very thin layer by watering it down as one of my prototypes didn't crack when I used that approach. I am also looking into high temperature silicone, but still trying to find something that fits my low budget and can handle the temperature (which I need to measure). My design only needs about 15w for a full extraction.

This is my first ever post on this forum!

Welcome to FC! i am honored that your first post was in my thread. best of luck on your vape.

Which glass tube are you referring to? there are three: the oven tube, inside the body of the cube; the vial, which holds the herb and drops into the oven tube; and, the draw tube, which is external to everything.

the heater coil, which is a ribbon not a round wire (used that for the first 11 years), is wrapped tight around the outside of the oven tube. so, the vapor air path is all glass.

i've been meaning to do an update ... still kind of pandemic shell-shocked these days, actually since the end of February.

Hi! I was referring to the oven tube. Ribbon sounds like a great way to get good heat transfer. I just applied a very thin watered down coat to a new oven tube prototype for my design, hoping it wont crack this time, but might try out some ribbon next!

I guess an advantage of a dry friction fit (no cement etc.) with the coil is that after repeated use if the oven tube gets dirty, it can easily be taken out and cleaned easily

well, it isn't advised to take out the oven tube due to the way the k-type thermocouple and the RT probe for the BBQ thermometer are tucked between the ribbon and the oven tube ... i'm sure there is a better way to mount them, but this currently works, is very reliable. i have labored over the probe positioning since the beginning.

fortunately, the oven tube does not get dirty. even after years of use with herb. i don't do concentrates in this vape (very much), so that may be another issue. a q-tip when the oven is still warm should be adequate. the warm draw tube (after a session) cleans up beautifully with a swab of a paper towel. the vial also wipes clean (i scrape a toothpick against the inside surface) when warm.

i tried some ceramic cement a number of years ago to try to add some thermal mass. the initial tests were not promising so i dropped that approach. this was before i switched to PWM heater control - which, in my mind, is the only way to fly ... it is like inventing fire. such heat control is revelatory. (i live a simple life, it would seem)

well, that's a problem as we roll into 2021, what with the new law prohibiting sale of vaporizers - or rather, regulating them out of existence for the small maker (me). looks like it will have to be purchased from a retailer. if and when.

after a december sales rush in my real world business i am finally getting back into the GCODE. it is always a struggle to switch mindsets between the projects in my life. and then there are the distractions: i.e. covid-19. i have been spending many hours studying the mRNA vaccine and the immune system ... just found a Dutch programmer's blog about reverse engineering the BioNTech vaccine - breaking it all down in computer programming terms ... can be very distracting.

anyway, i am working on a final piece of the maker puzzle. it dawned on me recently that the plastic bezel of the BBQ thermometer (which i hate and have hated from the beginning) can be replaced by a CNC Router version in cherry (which i love!!!) - where the grain of the wood will match the grain of the cube face around it. same idea as the bottom cover matching the grain of the cube bottom.

so, investing some time in a GCODE generator (Excel VB) to allow minor adjustments without the pain of my current tool. tomorrow!!! first prototype. maybe.

about the last thing i did (back in August) before getting diverted by work (spouse had a new book come out and that required updating the website, which required updating the programming tools for Windows 10 to get off Windows 7) and more recently covid, in order to get the cnc router in production mode is installing two 5-piece jigs so i can load 5 covers and 5 cubes at one time. parameterized the GCODE to do 5 cubes/covers to minimize tool changes. a little hard to see without the covers/cubes loaded, but there are vertical metal strips to align the pieces for milling.

so TL;DR - no pre-orders yet.

well, i finally tamed my monkey mind enough this weekend to finish refining my GCODE generator ... really hard to pull away from studying biochem about covid and the immune system, but i did it at least for a few hours.

so the big effort was to develop and test the GCODE to mill the bezel for the BBQ thermometer from the cherry wood:

here it is from the back side:

my POCKET-RECTANGLE generator needs to do a smoothing pass along the left and right edges.

here is with the LCD display and elastomeric contact strip (pink-black-pink strip below display) in place:

and with the BBQ pcb in place:

while i am in GCODE-mode i will update the cube and cover GCODEs and configure all to step across 5 pieces.

then i need to gird my loins to dig out and setup the old table saw and do some wood pre-processing, and cut out 20 cubes.

progress in the new year!!!

Well, well, well – another February.

End of January 2020, i was poised to start my February project with 20 of the brand new pcb design. Then i got distracted for most of the ensuing year by biochemistry and a little botany.

There were a few points of progress during the year – such as acquiring some new tools: cnc router, cnc leather cutter, shear-roll-brake tool. But all in all, thoughts of moving toward production were put on hold.

And, there was (? is, i guess) that pandemic thing - which kicked off an interest in mycology and, more recently and more passionately (i.e. spending a lot of time), in virology. So much to learn – always a click away. i am amazed by the internet every day – answering every question i throw at it, sometimes correctly.

By the end of August 2020, the GCODE for the cube and cover had been created and verified. Four faces of the cube, front and back of the cover. Then i started getting ideas – things that were impossible to mill by hand, but (conceptually) trivial with a cnc router. Like: a bottom cover that is cut from the cube stock, so the grain of the cover matches the grain of the cube. Like: a wood bezel to replace the plastic case of the BBQ thermometer, also cut from the cube stock so the grain matches. Plus, total control of the diameter of the cutout for the pcb (and cover), to accommodate the actual pcb diameter of +/- 0.01” on the nominal 1.7500” diameter requested. And now that is all done.

All this crap about the cover may seem trivial, but it eliminates a vendor (1.75” dowel supplier - with another uncontrollable size tolerance – didn’t want to get a lathe and do that additional woodworking myself) and provides a more aesthetic presentation, imho.

i have only played with the cnc leather cutter a little bit – can’t really say much more about it at this time, except it appears to be perfect for this task. It can cut the seven 1/16” thick matte board panels and the ten 1.5 mm thick (2 oz) leather cover pieces no sweat(shop). The leather case adds so much to the design and function – happy to see this might actually become real.

So, the main effort this February was to develop a GCODE generator specific for my manufacturing task, with 5 cubes and 5 covers mounted at a time. This maximizes milling per tool change, which operation takes several minutes. Using two router bits, plus a 1/16” drill bit (PIC programming port access) and a 60deg engraving tool (text on cover).

The plan is to have the router bounce between cubes and covers, rotating cubes when covers are milled, and flipping cover when cubes are being milled. At least that’s the plan. Each milling operation per face is only taking several minutes – still thinking 10 to 20 cubes per day is possible. And very easy to scale-up with more machines if needed.

And I got the GCODE generator done about a week ago. Using Excel, with a standardized sheet layout for each of the surfaces to be milled with specifications for the type of cuts, choosing from:
  • boss – round,
  • boss – rectangular,
  • hole – round,
  • hole – rectangular,
  • pocket – rectangular,
  • tap,
  • drill,
  • countersink
and the positions and dimensions.

Other sheets have specs for the four tools, offset locations for the 5 pieces in a line, and templates with boilerplate GCODE – feeds and speeds, parking the tool, etc.

And there are VB subroutines to generate the actual GCODE and output as a .ncc file for the cnc router controller.

i avoided doing this for most of the year, but in the end there was just no getting around it. GWizard took me far enough to create and test some GCODE but is far too cumbersome for small changes of position and size.

Now i just need to calibrate the position of 5 cubes and 5 covers … which is delayed due to the cold weather and an unheated workshop. At 73, cold slows me down ... i can find other things to do in the heated spaces.

But! Spring is coming. Wednesday will be in the high 50s … i will drag out the table saw and start some serious woodworking. Most likely.

Onward to 20 cubes!

I hope you do realize, that the vape ban only affects concentrate vapes. Dry herb vaporizers are safe from the law. You can even read the act itself, as it only refers to vapes that can vape liquids or concentrates. So yours would be safe...

Here's a link that talks about companies banding together to create a shipping company that will verify the age of the recipients, since USPS, Fedex, and UPS refuse to:


Quoted from the beginning of the article:

"The definition of products covered by the law is so broad that it captures not just nicotine vaping devices and e-liquid, but anything that can be used to vape any liquid- or oil-based substance (and the substances themselves)."

I like it! I hope that is indeed correct, and that this whole vape mail ban ends up being less of a big deal then it could be (depending on how it is interpreted and implemented)

Here's a little tease that what I said is correct, getting worked out hopefully, and even heard that the government was postponing it as well due to the confusion of what it's supposed to affect.... So it's looking brighter and brighter.....

I saw that and thought of callous the whole thing is to those that couldn't make it this far. Everyone else was hit too. I wish the industry would sue the government and win. There should be a penalty for their (govt's) ignorance. Did they procrastinate reading about the industry until the last day? Seriously!
