Update #13

You Make The Call after One Week of Vacuum

Thank you once again for continuing to tell your friends and associates about ThriftyVac® because your efforts just pushed us past the $42,000 mark, and we have been on a straight line upward for the past 14 days.  I am deeply grateful, which I’m attempting to show by my actions. 

Speaking of actions let me clarify this thing about a “SPECIAL BONUS REWARD,” which I promised to announce at the end of the ThriftyVac® campaign. I couldn't wait – because I wanted to be sure that the bonus was something that you really wanted. Accordingly, I decided to ask you what you wanted most. I got a lot or feedback and the top two things mentioned were (1) an extra ThriftyVac® Mason Jar Lid (TVL), and (2) an extra Check Valve. As it turns out, each TVL has a Check Valve embedded inside of it, which you can remove by hand. Thus the TVL bonus would satisfy those backers wanting TVLs as well as those wanting extra Check Valves. If the voting continues along these lines, the TVL will be your SPECIAL BONUS REWARD.  Further, since you already earned a TVL for reaching the $35,000 stretch goal, you would get a total of two TVLs added to your shipment.

There is one other thing: It is easier for some backers to use a battery-powered pump than a manually operated pump, and some of those backers already have battery-powered pumps supplied by other vendors. To accommodate those backers, I will provide an adapter that mates the ThriftyVac® Check Valve with the inlet port of battery-powered pumps. I can’t afford to buy production tooling to make the adapter, so I am now making them one-at-a-time on my 3D printer. Any Backer who really needs an adapter can request one, free of charge, when I send out the Post-Kickstarter Survey (shortly after the end of the campaign).

Now for the verdict – you make the call. Last Sunday, June 23, 2013, I used ThriftyVac® to vacuum pack a bag of almonds. (Subsequently, one of my Backers told me that almonds were a bad choice because they have pointed ends that can puncture thin polyethylene bags). I posted a photo of the vacuum-packed almonds in last week’s Update #12 and promised to post updated photos each week thereafter, date-stamped with a current news article clipping. The first such photo, date-stamped Sunday, June 20, 2013 (via the Washington Post front page) appears below. There are two photos, one showing the date printed on the Washington Post newspaper, and another one giving a close-up view. The photos show that the bag has retained almost all of its original vacuum – pointed almond ends and all.

BTW, many of you told me that the main reason you wanted ThriftyVac® was because it supported sous-vide cooking. The new Codlo Kickstarter project (http://www.kickstarter.com/projects/codlo/codlo-a-powerful-compact-controller-for-sous-vide) that I mentioned last week is off to a good start and meshes well with ThriftyVac®‘s minimalist approach because it allows you to do sous-vide cooking using a simpler, smaller, and more affordable system.

Thank you once again for your support.

Regards,

Tom Cannon

      Thank you Christopher.
      The Lid seems to be the overwhelming choice. The retail price of the Lid will be approximately $7, and Thrifty Backers will get two for free, if the voting trend continues in favor of the Lid for the SPECIAL BONUS.

      I'm all for an extra mason jar lid. That's good to know about multiples. I have friends and family who are unwilling to create a KS account.

      Hi Dan,
      The voting booth is right here, so you can cast your ballot right now.
      Yes, you have it right regarding pledges and units. You will have an opportunity to affirm what you would like when you respond to the post-Kickstarter survey.
      Regards,
      Tom Cannon

      Where is this voting you mentioned? Also can we double or triple our pledges for multiple units?

      Hi Marie-Andree,
      You may be right, but I would like to focus my energies on meeting commitments to my existing Backers, and address add-on opportunities a bit later.
      Regards,
      Tom Cannon

      Tom, I don't think that rule is for add-ons, but for the main product. So if you annonce Add-ons, you should be able to provide check valves at a unit price + shipping.

      Hi Nacho,
      Kickstarter rules prohibit selling multiples units of hardware. However, you may contact me directly at Tom.cannon.jr@gmail.com and I can help you get the parts that you need.
      Regards,
      Tom Cannon

      I would support the reward of simply extra check valves. I continue to be interested in not one or two, but perhaps 12 to 15 extra Check Valves which I can then install in lids of a variety of other containers. Would it be possible to pay a few extra dollars and have an add-on purchase available for 10 Check Valves? The only info I think we'd need form you is the diameter hole we'd need to drill into whatever lids we want to put the CV in. Many thanks for considering this.

      I have no intention of boiling my dinner. I am looking forward to a great way to force infuse meat . And then freezing my cooked results for later. Your almond experiment is enough proof for me.
      And for everybody's information: Those expensive bags aren't perfect either. I have had some valves in those fail.

      Hi Andros.
      Both the seal and the plastic are porous. Please see the explanation in the FAQ section. The little gadgets that you describe work sometimes on some bags (depending on the bag thickness, contents, and smoothness), however we need a consistent solution. Also, heat sealers cost money and add an additional step in the process. Accordingly, we have identified other methods for retaining the vacuum for longer periods of time. Finally, once ThriftyVac is generally available, bag manufacturers will have an incentive to produce bags having better seals, out of better materials that work exceptionally well with ThriftyVac.

      Thank you for your suggestions.
      Regards,
      Tom Cannon

      i have an idea. is it the plastic that is porous or is it the seal at the top? although i dont know what the tech is, ive seen these little gadgets that press down and can sort of almost melt plastic together to form a seal. if you used a device like that, do you think we could make a better seal at the top and therefore make the bag able to hold its vacuum better?

      i would be fine if this extra sealing process is destructive/non-reverse-able because these plastic bags can be found for less than $0.20.

      Yes Daniel, you are right, I meant June 30th. That date is visible in the lower right portion of the photo. Thank you very much for catching this.

      Hi Michelle.
      I had a similar experience as yours. I invented ThriftyVac® after I had already bought one of those big boy electric vacuum machines.

      Creator michelle kelley on June 30, 2013

      I really like this little device idea, because it doesn't need power. We have one of the big boy vac machines, but it's so pricy, I only use or for meat.

      We use ziplocks all the time, so this will be perfect!
