DipJar Puts New Twist on Cashless Tipping

DipJar, a startup with offices in New York City and Boston, digitizes the all too familiar tip jar found at many coffee shops and restaurants. It allows credit and debit card users to leave a tip with a simple swipe of their card, providing service employees with yet another opportunity to collect that well-deserved gratuity.

DipJar lets coffee shop patrons leave quick and easy tips in a single swipe.

At a business where a DipJar is present, customers simply “dip” or insert their card into the device to leave a tip in an amount set by the establishment. The DipJar, which houses a card reader, circuitry and software to complete the cloud-based transaction, displays the amount tipped and makes a “change clinking” sound to notify employees of the payment. DipJar also is positioning the device as a way for charitable organizations to collect donations.

The Reviews Are In!

We recently published a comprehensive, 72-page “Digital Manufacturing for Dummies” book that covers the benefits of using additive manufacturing (3D printing), CNC machining and injection molding for custom prototyping and low-volume production.

Well, a few editors of industry publications have had a chance to read and review the book. Here’s what they’re saying:

5 Design Considerations for Multi-Cavity Molds

Moving from a single cavity mold to one that produces two, four or eight parts at once seems like an easy way to increase production volume and reduce part costs. This can be true in many cases, but only if the right steps are taken and the requisite homework done first.

The 3D CAD model for a multi-cavity mold.

Designing a part for multi-cavity molding is not as simple as copying the CAD file for a single-cavity mold multiple times. It’s important to recognize that parts that behave perfectly in single-cavity mold might not play well with others, at least not without first making some tweaks to the part, the process or even the material.

In July’s tip, we look at important design considerations for multi-cavity molds that include gating, side-actions and pick-outs, material flow and how family molds are used differently than multi-cavity tooling.

Design Tip: Leveraging Low-Volume Injection Molding

Investing $50,000 or more in high-volume steel tooling is an inherent financial risk that comes with a move to large-scale production. Compounding the risk is months of idle time as you wait on your steel tool to be ready when you could be iterating part design or even producing products that generate revenue.

11 Reasons Why Launching a Crowdfunding Campaign is Valuable

By Joel Townsan, creator of the Flipout Screwdriver

When my crowdfunding campaign failed, I was pretty devastated. I couldn’t figure out what went wrong — my Flipout Screwdriver had just won the Proto Labs Cool Idea! Award, had gotten tons of press coverage and people really liked the video (not to mention the product). Yet, I fell short, raising only $17,000 of the $50,000 goal I needed to move forward. I’ll admit, the product was priced a little high ($130 compared to most electric screwdrivers that go for $30 to $50 in stores), but I still couldn’t understand what went wrong. I had spent six weeks emailing every gadget magazine, tech blog and DIY forum I could find, but was somehow unable get my project into the coveted “Popular Products” category on Kickstarter — a section on the site that can seemingly make or break a product overnight. I thought it signaled the end of Flipout. Fortunately, it was just the beginning.

The Flipout cordless driver has a 360-degree range of motion with 380 possible configurations.

In addition to simply raising capital, there are a lot of bonuses to running a crowdfunding project that can actually benefit an inventor more in the long run. When the Kickstarter clock expired, I thought my project had failed, but really, it was the beginning of a crazy roller coaster ride that would result in a DRTV deal with Lowe’s — one of the largest big box retailers in the world. Regardless of the success or failure of a Kickstarter project, there’s a lot of good that can come from the campaign. It’s kind of like running a marathon; it takes months of training and then you run like you’ve never run before, but once you cross that finish line, it can be life-changing. Thus, my excitement crowdfunding.

Here are 11 reasons why every inventor and entrepreneur should consider a crowdfunding campaign:
