About this project
PEGS began as a simple working prototype built in a single day by one of Chimp Systems' founders. After sharing a demonstration video on YouTube, we knew they were too big to keep to ourselves. We received hundreds of views and emails from people asking to buy a pair. Here's the video that started it all!
Here at Chimp Systems, we do our best to design and build things so that the people who are in the market for a product can easily get it! We never want price to stand in the way of someone owning one of our cool products. We could have built and sold PEGS for the initially projected $90 dollars but we wanted to invite everyone to the party, so we made affordability one of our top priorities. We worked closely with our manufacturers to create a product that is high in quality, yet low in price. It took months of hardware and software revisions to get to this point and we know we're finally ready. We could not be happier to bring you the finished product!
PEGS are a light weight and self contained pair of LED glasses. Unlike other light up glasses that just blink around the edges, PEGS feature display patterns that utilize the whole face and scrolling text as tall as the frames, all without interfering with your vision.
The PEGS in action!
The batteries are mounted on the glasses, so there's no wire or external battery pack; just unfold them and they light right up. Yes, they are folding! They fold like regular glasses, so you can put them in their case and carry them in your pocket or purse.
PEGS are powered by two coin cell batteries that can provide over 12 hours of continuous use. We purposely chose a battery that is low in cost and readily available. There is no need to go hunting for a specialized battery online, just stop by your local supermarket and pick some up!
If you know how to put on glasses and take pictures with a camera you will have no problem using PEGS. As soon as you unfold the arms, they light right up. We have also included a simple on/off switch to prevent accidental operation. To change your pattern, simply click the top mounted button on the right, just like a camera. To cycle though your custom text messages, click the top mounted button on the left. Simple! Custom text messages can be programmed using a method similar to texting on an old cell phone. Simply press the left button until you reach your desired letter, then move on to the next character. You can even program up to 50 individual characters in each of the 4 memory banks!

PEGS have been through three distinct iterations. This first set we developed is the cardboard frame prototypes. These are the ones seen in the original YouTube video. They were thrown together using some spare parts, cardboard, hot glue and lots of extremely small wire. Most of the initial concepts were forged with this pair including the batteries on board, shutter shade style frames, 16 columns of LEDs, as well as a few other features. This pair was built as a one-off proof of concept prototype. There are many things that needed to be changed in order for the PEGS to be mass produced.
The second stage of development was done completely on the computer using a combination of Eagle CAD, Eagle UP and Sketch Up. Many different models were designed and visualized in this 3D environment. The ICs were originality on the sides of the glasses but were moved to the front after being ruled impractical having 15+ electrical connections per side. We also attempted to move the batteries to the front as well but it severely degraded the 'look' of the PEGS. With the circuity falling into place, it was time to work on the outer fame. The initial concept was to use a three piece plastic injection molded frame to hold the three PCBs (two battery boards and one front board). The three plastic pieces would be two sides and one front that would allow for hinging. Spring contacts were built into the battery PCBs and mating pads were added to the front PCB. The PCBs were sent off for fabrication while the plastic frame was designed. After many budget reviews, manufacturing checks and crafty engineering, the idea to use an outer plastic frame had to be cancelled. The added cost to the PEGS was to great with very little improvement when using only PCB material. When the PCBs arrived, we strapped on some cardboard in order to test and debug the design.
The final stage of the design was to make the PCBs form the entire frame. Sourcing and incorporating a hinge was also one of the final tasks for us to accomplish. The PCB part was easy, as we simply made the frames thicker and shaped the battery PCB into glasses "arms". The hinge was a little harder since they are usually custom built. We eventually found the perfect pair! The manufacturer was kind enough to send us four sample sets (enough to build two pairs of PEGS). This was perfect for mechanical testing of the hinges and mating connectors. An extra part was added to the PCB to allow a rigid connector to hold the PCBs together and provide the needed electrical connections. If you notice in some of the video shots, the glasses are fixed (non hinged). This was simply done for ease of demonstration. With the hinges tested and working great, the PEGS are ready for you!
Now that we have finalized the PEGS design, they are ready for you to own for yourself!

Risks and challenges
So far, we have produced and sold two consumer products and made a few custom products for individuals and businesses. We have experience building tens, hundreds and thousands of units so we've learned how to scale our operations accordingly.
We have done our best to minimize any risks involved with this project. We have fall back manufacturers, so if problems arise with one, we can switch to another. We used proper DFM (Design For Manufacturing) techniques to help increase manufacturing efficiency of the PEGS.We also perform quality assurance inspections including full product testing on every item we sell.
The main risks associated with this project are unavoidable delays. These include natural disasters that effect supply chains, delays in customs, lost shipments and incorrect shipping labels.
-Customs can hold goods and 'forget' to inform you about it (unfortunately- or fortunately for you rather- we've had some experience dealing with Customs). We stay proactive with this process and use package tracking to uncover any hold ups before they become a problem. Sometimes a simple phone call can get a package moving again.
-Natural disasters are by far the hardest thing to overcome. If an earthquake causes massive flooding at the LED factories, we would experience delays in manufacturing, which of course would create a delay in shipping. There is not much we can do in those situations.
-Lost shipments happen. Even the best couriers can misplace a package. We use shipping insurance to cover the cost of replacing the items but a delay is unavoidable in this situation.
-Mistakes are very unlikely, but they can happen. Sometimes labels can be printed wrong, or boxes can be packed incorrectly . If you don't receive your items, receive the wrong items or receive damaged items, email us so we can resolve the issue.Learn about accountability on Kickstarter
