Underdog Log Vapes

Yes, I originally bought the 10 foot but it stopped working after a couple months, well it didn't stop working but fiddling around trying to get the cord in the right angle was becoming bothersome, so later I got a 15 foot cord and it seems to have the same issue.

The cords we get (bought in bulk) usually work pretty well but I think they're pretty lightweight. You might try one from Amazon and see if theirs are any better.. if so let me know and maybe we can buy ones like those next time.

Here's some on Amazon: http://www.amazon.com/s/ref=nb_sb_n...eywords=2.1mm x 5.5mm DC Plug Extension Cable

A male/female 2.1mm is what you're after, in whatever length you need.

i played hooky at work today stayed home in my small backyard w my dogs, hitting my ud twig, listening to the sound of birds and it's gently drizzling w light thunder but still nicely bright. wow, the ud with the gong & a nice bubbler is really rocking me , and the wood just gives it a 'natural' kinda-feel. a lot of people out there making a living every day, and it ain't easy so i'm just thankful i got this day to share w you underdoggers...

thanks dave, here's one for you .....hhhhhhhh.....sssssSsssssSss ......ssssSsss...ssssSssssSss..ssSssssss....... ( and my dog's chasing a butterfly )

I recently had a friend tell me that my Underdogs are his favorite of all my toys and that he will be purchasing one of his very own this week! Looks like the beauty, quality, and performance of your functioning artwork has spoken for itself...again.

I can't wait to try out the "neighbor's dog"!!

On top of all that, throwing in their awesome customer service & price tag, well, you got yourself a wonder of a vape

my UD is kicking ass.. i just got it a new power supply
i really needed that..

Hey UDs hope you're all having a great weekend.. haven't posted in a while so figured I'd stop by and say hi.

Working on pieces for the next refresh, still a week or a little more away though. Hoping to have some of the mini-VVPS back in stock by then, wasn't too sure if I was going to reorder and ended up procrastinating until we ran out lol.

Speaking of VVPS I've been buying and testing different ones again trying to see if I can find anything much better. So far not a lot of luck, of the 10 different ones I tried in the past two weeks 8 of them were such junk that they didn't even last 24 hrs. One of the remaining 2 looks a bit weak but maybe it'll pan out, the remaining 1 is looking somewhat promising.

This is the promising one, it's a very lightweight lab-style supply.. obviously not real lab grade but at least they made a little effort lol. Might be an option to consider for those of you thinking about buying a (hopefully) better VVPS than the minis. Lab-style VVPS on eBay

Alright, back to the shop.. laters.

Hey Guys,

So it's been a year and half I've been using my UD and it still works as a charm. It used to be on 24/24 during the first 365 days but now I only plug it once in a while since I decreased my consumption.

I need a new power supply and I did not come on this site for a while. I can see there is a lot of discussion about changing output voltage of your charger. I would like to know if those kind of devices really offer something more than just a regular universal power supply which I can change the voltage output to 13.5.



Here is an example of what I'm talking about: http://www.conrad.fr/ce/fr/product/...0-V-24-V-DC-2-000-mA-48-W-VOLTCRAFT-SPS24-48W

You have the standard 12v output but you can swith it to 13.5v. Would that be risky for the heat core of my UD? what do you think about this option?

thank you!

ps: @underdog Dave, I just noticed the heat core seems to be a little "detached" (I don't know what would be the word) from the wooden unit. It does not compromise the efficiency and it is probably caused by the fact my UD suffered from several falls over the time :/. Do you think it may be a problem in the future? is there something I can do without needing to send it back to you from France (which would be expensive)... ?

I hope I will still be able to use my UD for a long time.. what I'm sure is that if it dies, I will not hesitate to buy a new one..

thanks for your time

This looks like the same one only $20 http://www.storeinfinity.com/new-yh...justable-variable-dc-power-supply-15v-2a.html

i've always wondered about this:
how does an ud unit look like inside after some years of usage?
Does a lot of the material collect?
Does it get black?

Thanks dave for the great UD

I get to try this UD tonight after work, my buddy said he's really impressed with the quality of craftsmanship!


Since Dave was out of the VVPS minis, he ordered a wall wart and I'm gonna trade him one of my minis since I have 2 that I'm not using ATM. That way he gets to adjust, and I get to try the brick, win-win! I'm also gonna take some bubble hash and keef and show him how to make the perfect layered nylon stem for one, gives about 10-15 strong hits and an amazing effect. Tonight should be great!

Hahaha.. thanks placetime!

I'm going to try and wrap things up early today so I can go do something very similar to that..

Hope I can pick up a piece during your next refresh Sold my purple days a long time ago and been wanting to get back into the vape world. Log vapes are definitely one of my favorite styles.

Nylon stem love! I love going back in time! Bringing back old habits! 2 bowls then smash them up finer after one hit, then put both bowls into one bowl. 2 fresh hits and a monster last one to get it all out.

Hi Muut - glad to hear you're still enjoying your European Underdog after all this time..

If that power supply is a regulated one, if it actually outputs 13.5v instead of just saying that but outputting higher voltage it would probably work just fine. You'd probably have to try it and find out, carefully making sure it's not overheating the UD.

Re: the detached/loose core its probably an original core which we screwed in place and those ended up loosening over time as the wood degraded around the core. With the way they were built and installed there's not much that can really be done to tighten/repair them unfortunately. If shouldn't affect the efficiency though as you noticed, at least if/until it moves enough to break or short a wire and then the UD is probably done.

Oh man I was all excited and went to order a couple of those for testing.. and discovered they're charging $40+ just for shipping. I hate it when vendors do that kind of sneaky shit..

Update for the Dogpound: Though I have a "classic core" model, I got an old Zap stem from Dave before he introduced the new core and his own stems. And I use it with my classic core and I LIKE IT!

I had complained in this thread before how I had not been roasting stems to the color of my liking. I soon discovered the fault of my "stem packing." The silicone stems are amazing for loads greater than maybe .05 grams, but weren't giving me that "almost as dark as coffee" dark roast that I was looking for for really small loads. A good roast not only depends on the heat core temperature, but have everything to do with airflow. And restricting some airflow is good for high temperature roasting. But how do you restrict airflow when the amount of material in your stem doesn't even cover the screen?

Fast forward to the present and the new core (and nylon stems) has resolved this issue. By narrowing the diameter of the roasting stem (5/16 ID at the stainless steel tip), the same amount of material gets "packed tighter" and roasted darker.

But those of us with classic cores? The nylon stems seem to work damn well! Just hold stem tip directly against heat port screen (which, on my classic core, is about 1-2mm recessed from the top of the heat port walls) and draw. NOTE- the downside of using a classic core Dog to do this is that you need two hands...one to hold the stem and one to hold the Dog.

I'm getting super dark roasts with VERY VERY little material. In fact, I actually combusted once using this method (via the wallwart running HOT, which it seems to do, particularly in the evenings), so watch your roast, playa!

i have been wondering why those zap stems and the classic cores don't work right w/ each other.. i was wondering if it was a ID issue.. or if it was because of that little screen in the core.. because it seems that screen can be removed and replaced, right?.. my screen kit has extra screens for that.. maybe the screens can be pushed down further some?? i have never wanted to try messing w/ that little screen, but i have been kind of wondering about it for the past few days. anyways, cool to hear it works w/o messing w/ the screen.. i had a feeling it could work w/ the classic cores.

The screen in the core is not meant to be replaced and for most practical purposes cannot be. Screens in the screen pack are replacements for various stem screens.

Ohhh FedEx just showed up with a couple hundred wall-warts and VVPSs.. guess I better stop slacking and get back to work on pieces for the refresh.

So... I left my Dog today running at 15v for about 9 hours =/ I have an adapter with a turn-able switch that goes from 12 to 15; moved it on the morning before work to 15 ''for a few second'' just to get a one big hit before going to work, and guess what, I forgot...

Luckily, it seems that the unit is fine and it didn't started any fire I let it cold down for a bit and then plugged it back on 12v and it is hitting normally... I get at the long term I may have caused some damage, but so far I'm amazed at the dog resilience

As long as your power plug isn't loose and the vapor tastes okay, sounds like you dodged a bullet!

Hey UDs, we're still hard at work to get the pieces up for the refresh. We lost a few days in the schedule because we had a piece of equipment die. We're aiming to get the new pieces up before the weekend's over.

On another note, our email server via the website has had some issues the last few days. If you tried to send us a message through the website and haven't gotten a response, please message us through FC, Facebook or send us a direct email. We're working on the issue and should have it resolved this weekend as well.

Hey Dogs we're almost caught back up, pieces for the refresh are in testing and nearly done.. will probably let them go through tonight and pull them in the morning. Lost a few days for some forced machine maintenance but everything is back on track now.

(More) patience grasshoppers..

Good news! Underdog pulled all the pieces for the refresh and did final assembly today. We're planning to take all the pictures tomorrow and have them on the site and live tomorrow evening.

Thanks for all the patience Underdogs.. the new pieces are up!
