lineScale 2 project update #4
Production STARTED on 19.1.2019

Oh yeah… with the trustful support of the community we really made it.
Funding was successful and production is now running.

We send a sincere THANK YOU to all the backers for the 42 pre-ordered linesScales. We truly value the trust and faith you put in us by helping to crowdfund this project.

So if you were hesitating to pre-order before production start, now’s the time to strike – there’s still 8 easy-birds left!

Watch the video on Facebook for some indepth details demonstrated on a 3D-Printed lineScale-2 prototype.

We’re sooooo excited to embark on this fantastic journey!
Stay tuned, there’s a lot more to come in the next weeks…

lineScale 2 project update #1
12.12.2018

Good news: Looks like we’ll be able to reduce the weight to about 500g while easily retaining 60kN MBS.

Our production partner has also confirmed a scan rate of 50-100Hz today, which significantly speeds up the load readings to one every 10-20ms!

Theres still more than half of the 50 early bird deal units available 😉

Every backer is needed now to reach the 50 pre-order units so this awesome project can transition to production asap.

Cheers
– the lineGrip team

lineScale 2 project update #3
29.12.2018

The final design and production schedule is established!

Now its up to you, all the yes-voters of our FB survey who have not ordered yet. Cummon, be true to your word, don’t let all the active supporters down! We only have 16 more early-birds to go… lets make this happen by the end of 2018 🚀

Grab your 399€ early bird deal (*) now!

We had 67 yes votes with some multiple order announcements, adding up to 86 prospective pre-orders in total. So far we have 34 orders, thats just 16 short of production launch. With your support we can reach the 50 units necessary in the next 3 days.

(*) regular retail price will be 499€ (export w/o tax), thats 594€ (incl. tax) for orders within the EU.

We promised to pull this off, if enough backers come forward, so here it is 😀

Thank you all for the lively participation and the overwhelmingly positive feedback on the Facebook lineScale 2 survey!

To be honest, we had not expected that many potential backers for this project. In just 4 days we have 66 Yes-Voters (44%), some of which announced to pre-order multiple lineScales right away, as soon as available… this adds up to 84 prospective pre-order units, which is a fantastic number 😀

Of course we’re aware, that clicking a simple poll button is different from placing an order, and thereby contributing to a crowd-funding style project, by paying the early bird bargain 5 months ahead of delivery.

However, we have good faith in the community, that most positive voters will indeed be true to their word and commit to the pre-order.

Therefore this pre-order article was released on Dec. 10 2018 at 20:00 CET.

50 units of the first batch are allocated to the 399€ early-bird deal on a first come, first serve basis 😉

The 50th sold lineScale will trigger full steam project launch – design finalization, prototype production and app development. We don’t start from scratch, and can build on the solid base of the lineScale v1, therefore we’re positive that 4 months will easily suffice for development and production of a first 100 unit batch.

We’re excited. Lets make this happen, together!

Thank you in advance for your trust and support

Andy & Arthur Riedrich
and the LineGrip Corp. team

REFUND NOTES
In the unlikely event that the projected minimum of the 50 necessary pre-orders for project launch is not reached, we will fully refund all payments in the first week of January 2019.

Please be aware: Since project funding is dependent on the total number of orders, your payment will only be refundable in above mentioned event of falling short of minimum total order quantity.

PROJECT NOTES
We personally guarantee with our good reputation that the lineScale 2 will meet up to your expectations, that it will be manufactured in the accustomed lineGrip Corp. highest quality, and that we will do our very best to maintain the planned dispatch date of May 2019.

On a regular basis we will post project updates – as you may know it from crowdfunding platforms – and try to involve each customer in contributing with ideas and requests to end up with the best product, that meets as many requirements as possible.

30kN WLL, about the size of a large hand, 22mm thin, and ca. 600g light.
For highest possible safety, the lineScale unibody is milled from a solid block of high-strength aviation aluminum, which results in 80kN breaking strength. The generous D-Shape chamfered attachment eyes are cross-load proof and will accept almost any conceivable connector such as steel shackles, biners, industrial slings, ropes, webbing and soft-shackles.
Bluetooth connectivity allows you to display/log the load values on your smartphone and set a custom load alarm threshold via the lineScale-App.
It comes with a light, perfectly fitting protective felt pouch.

Safety aspect
This device is milled out of one solid block of high-tensile aviation aluminum (LY12CZ), giving it a whopping 80kN MBS. In terms of safety this is the best deal you can get. Theres no bolts, screws, rings, pistons or joints that could possibly fail… this is the security of mind you need when leaving the scale in the highline rig while walking it!

Versatility
The lineScale 2, with its 80kN MBS, is perfectly suited as a bomber, generously dimensioned, nicely organized anchor/distribution point for your highline rig. The large omnidirectional, cross-load proof eyelets can easily accommodate 6-8 strands of 10mm rope from your equalizing anchors, which makes multi connector management an ease.

Working priciple
The lineScale works by the priciple of material micro deformation: Wikipedia – Strain Gauge

User configuration
The displayed unit (kg, lb, kN) and the auto power off time can easily be selected and saved as preset by the user.

High Tech Power Management
If no load change is registered for the preset shutoff interval the device will auto power off. It was essential for us to assure, that the scale does NOT calibrate its sensors to 0 when powered on, but immediately shows the current load. This enables you to power on and off manually anytime when you need a load reading. This saves an enormous amount of power and makes your scale go for months without having to recharge.
Of course the device has a low battery warning indicator, but additionally it also displays the voltage reading of the battery pack when powering on, so you can recharge in time. The lineScale also has a low power emergency operation mode that ensures your batteries are not drained without you noticing. When power is in the critical range it will automatically power off after 3 minutes in any case to save power.

Accuracy
The 24Bit pro AD-Converter with dual strain gauge configuration has a resolution of 1kg with a measuring error of less than ±1% (only inside the “sweet spot” area of 300kg – 1500kg / 3kN – 15kN, which is 10-50% of maximum load). Please note: Below the “sweet spot” area the measuring error might be up to 15%, especially under 100kg… this device is NOT a precision micro scale! See “Limitations” tab for further details.

Scan Rate
The sensor scan rate (cycle rate) is 40Hz, meaning the lineScale reads and calculates the sensor load every 25ms, which makes it sensitive for fairly short peak loads. We promise to aim for the lowest possible scan rate within our budget.
Any peak load shorter than 25ms may be missed by the sensors, however this is very, very unlikely for slackline use. See “Limitations” tab for further details.

Please note: Specs subject to change slightly during design and production phase!

WARNING!
This device is NOT a professional analytical device or laboratory/reasearch qualified dynamometer on which to base a single 100% reliabilty calculation of an unredundant life support system! The lineScale scans the load every 25ms, which might lead to the fact, that an ultra short peak load is missed, such as may occur when doing anchor bolt testing with short slings in factor 2 falls, for instance. It may also lead to slightly reduced reading of a leash fall in a very short highline, because the 25ms reading interval might have occured a few milliseconds before or after the peak load.

Please note: Specs subject to change slightly during design and production phase!

There will not be any extra costs from our side on the 399€ early bird price – no taxes, no shippig, nothing… no matter where you live.

But please note if you have your lineScale shipped to countries outside EU:
Your local customs office might charge you import taxes and customs fees when importing to your country. Due to the many different regulations worldwide we are unable to list and specify all potential costs that may arise for you during the import.
Please check with your local customs office if you’d like to get clarity about what you might be confronted with once the lineScale is dispatched to your location in May 2019.

To facilitate this you may use the following customs specs:
