Kickstarter started out as a platform for group buys, low-volume manufacturing, and a place to fund projects that would otherwise go unfinished. It would be naive of anyone to think this would last forever, and since these humble beginnings, we’re well into Peak Kickstarter. Now, Kickstarter, Indiegogo, and every other crowdfunding platform is just another mouthpiece for product launches, and just another strategy for anyone who needs or wants money, but has never heard of a business loan.
Of course there will be some shady businesses trying to cash in on the Kickstarter craze, and over the last few years we’ve done our best to point out the bad ones. Finding every terrible Kickstarter is several full-time jobs, but we’ve done our best to weed out these shining examples of the worst. Following up on these failed projects is something we have been neglecting, but no longer.
Below are some of the most outrageous Kickstarters and crowdfunding campaigns we’ve run across, and the current status of these failed entrepreneurial endeavors.

We all remember the good ol’ days when smartphones were just getting started. Realizing that we could take a fully functional computer and shove it into something the size of a phone was pretty revolutionary. Some of the early phones like the original Motorola Droid had some features that just aren’t very common today, and [liviu] set out to fix this situation by adding a sliding QWERTY keyboard to his modern smartphone.
The build started with a Samsung Galaxy Note 4 and two cases: one for the phone and one for the keyboard. [liviu] found a small phone-sized bluetooth keyboard and removed all of the unnecessary bits before shoehorning it into the case. He then built the sliding mechanism from parts out of a PC power supply and two old flip phones and then was able to piece the two halves together. Using the two flip phone hinges gave this case the additional feature of being able to flip up after sliding out. The result is a modern smartphone with a fantastic and classic smartphone twist that looks very useful.
We’ve featured projects that give new life to old smartphones, but this might be the first to give old life to a new smartphone. We wouldn’t mind seeing more flagship phones that come with these features, but [liviu] has done a great job of making up for the manufacturers’ shortcomings!

As a society we are moving away from land line phones while mobile devices are becoming more and more prevalent. It is not uncommon for people to only have a cell phone and completely skip out on the corded home phone. While this move may be for convenience, there is one difference between the two phone types that didn’t ring well with [Stavros]. He’s an angry phone talker and misses the ability to slam down a phone handset. Now [Stavros] could just have a corded home phone but he wanted a mobile option for handset slams so he came up with a project called iRotary. It’s an old school rotary phone converted to be battery powered and uses cell phone networks for making calls.
At the heart of the project is an Arduino. The Arduino is a great choice as it can easily decode the phone’s rotary dial pulses. The Arduino code takes all of the individual dialed numbers and combines them into a phone number. The sketch is set up so that after the 10th digit is read, the phone call is placed using an off the shelf GSM shield and associated library.
Since a battery would be necessary to make this phone mobile, one was installed inside the case along with a charging circuit. [Stavros] hasn’t done any long-term endurance studies but he has had the phone on for several hours at a time without any problems. So, now he can rest easy knowing that an angry hang-ups are never out of his reach, regardless of where he may be. And since he’s a nice guy, he’s made the source code available for anyone wanting to make something similar.

The Nokia 3100 is a classic in the circles we frequent. The LCD in this phone is a very cheap and very common display, and it was one of the most popular phones since the phone from Bell, making it a very popular source of cool components.
Now everything is an Internet of Thing, and cellular data for microcontroller projects is all the rage. [Charles] thought it would be interesting to use the famous Nokia 3100 to transmit and receive data. After battling with some weird connectors, he succeeded.
The Nokia 3100 doesn’t have a USB connector, as this phone was made before the EU saved us from a menagerie of cell phone chargers. Instead, this phone has a Nokia Pop-Port, a complex connector that still has TX and RX pins running at 115,200 bit/s 8N1. By fitting a USB socket onto a prototyping board, adding a few level shifters, and connecting the pins in the right order, [Charles] was able to get his Arduino talking to an old Nokia Brick.
[Charles] isn’t quite at the level of sending SMS from his confabulation, and even following a tutorial from [Ilias Giechaskiel] didn’t work. [Charles] is looking for help here, and if you have any suggestions, your input would be appreciated.
There is a problem with using a Nokia 3100 as a cheap Arduino cellular shield: it’s only 2G, and sometime soon those cell towers will be shut down. For now, though, it works, and once those 2G towers are shut down, there are plenty of options with cheap, early Android and iOS phones.
[Seandavid010] recently purchased a 2004 Volvo. He really liked the car except for the fact that it was missing some more modern features. He didn’t come stock with any navigation system or Bluetooth capabilities. After adding Bluetooth functionality to the stock stereo himself, he realized he would need a secure location to place his iPhone. This would allow him to control the stereo or use the navigation functions with ease. He ended up building a custom iPhone mount in just a single afternoon.
The key to this project is that the Volvo has an empty pocket on the left side of the stereo. It’s an oddly shaped vertical pocket that doesn’t seem to have any real use. [Seandavid010] decided this would be the perfect place to mount his phone. The only problem was that he didn’t want to make any permanent changes to his car. This meant no drilling into the dash and no gluing.
[Seandavid010] started by lining the pocket with blue masking tape. He then added an additional lining of plastic wrap. All of this was to protect the dashboard from what was to come next. He filled about half of the pocket with epoxy putty. We’ve seen this stuff used before in a similar project. He left a small opening in the middle with a thick washer mounted perpendicular to the ground. The washer would provide a place for an off-the-shelf iPhone holder to mount onto. [Seandavid010] also placed a flat, wooden paint stirrer underneath the putty. This created a pocket that would allow him to route cables and adapters underneath this new mount.
After letting the epoxy putty cure for an hour, he removed the block from the pocket. The stick was then removed, and any gaps were filled in with putty. The whole block was trimmed and smooth down for a more streamlined look. Finally, it was painted over with some flat black spray paint to match the color of the dashboard. An aftermarket iPhone holder allows [Seandavid010] to mount his cell phone to this new bracket. The cell phone holder allows him to rotate the phone into portrait or landscape mode, and even is adjustable to accommodate different sized phones.
As convenient as cell phones are, sometimes these power-hungry devices let us down right at the worst time. We’re talking about battery life and how short it is in modern cell phones. Sure that’s totally inconvenient sometimes but it could be way worse. For example: during a natural disaster. A cyclone hit [Ganesh’s] home city and the entire area had lost power for 10 days. He couldn’t plug in his phone to charge it even if he wanted to. After realizing how dependent we are on the electrical grid, he did something about and built a phone charger out of parts he had kicking around.
The charger is quite simple. The user cranks on a DC motor and the output power goes into a LM2596-based step-down voltage regulator. The output of the regulator is then connected to a female USB connector so that any USB cord can be plugged in. As long as the motor is cranked fast enough to put out at least 8vdc, a steady stream of 5v will be available at the USB connector. Max current output of the system has been measured at 550mA.
[Ganesh] admits this isn’t a practical every-day charger but in a pinch it will certainly do the trick. It is even possible to build a makeshift charger out of a cordless drill.
