What is Solderdoodle?
Solderdoodle is a portable, cordless, USB rechargeable soldering iron. It is based off my original Open Source project: "Solar Powered Soldering Station" http://www.instructables.com/id/Solar-Powered-Soldering-Station/
Solderdoodle does what other portable soldering irons have failed to do, and that’s the ability to last hours and charge the soldering iron from a USB port. You can literally go anywhere and still have a way to charge your Solderdoodle if there is a laptop, USB battery, wall adapter, or even a USB solar charger nearby!
Solderdoodle uses a high-efficiency, high-power charge controller from Maxim and uses the same battery that's used in the Tesla electric car, which is the best battery of its kind. The soldering iron tip is replaceable using off-the-shelf components.
After learning how to use 3D printers, one of my friends asked if there was such a thing as a USB soldering iron and I said that I had instructions to build one, but the battery was external. I then realized that I could create my own case design on a 3D printer and put the battery, charge controller, and other parts inside as one single unit! It worked!
Where Do the Funds Go and How Long Will it Take to Finish?
The Solderdoodle is designed be as simple to manufacture as possible and it is always being refined for the most efficient assembly. Our suppliers have given us great quality prototype parts and they are ready to manufacture the components in larger quantities. Typical manufacturing lead-times for components are about 30 days and test batches are always ordered before going in to large-scale production. Realistically, it should take about 4 to 5 months to set-up shop, order parts, manufacture parts, inspect components, assemble each batch, final test each unit, package, and then ship them.

A special thanks goes to the Brainsilo hackerspace for letting me use their 3D printers and other resources to get Solderdoodle made!
Risks and challenges
I have a M.S. in Mechanical Engineering with over seven years of experience in the semiconductor industry. I also gained a lot manufacturing experience working at my Dad's sheet metal shop since I was a kid. Unforeseen issues that can delay the shipment of rewards to Kickstarter backers include, but are not limited to:
* Delays in receiving components on time from vendors.
* Delays from rejected parts during inspection.
* Delays from the carrier in shipping the product to the Kickstarter backer.
As a backer of other projects, I understand the importance of honest communication, even if the news is not so good, so I will make it a priority to answer all backer questions as fast as I can and give updates as soon as possible. We are on this journey together.Learn about accountability on Kickstarter
Solderdoodle solders up to 24 gauge wire with leaded and non-leaded solder. Perfect for small Arduino type projects.
Yes! I bypassed the 5V DC-DC converter and wired the heating element directly to the charge controller output and Solderdoodle was able to reach over 700ºF!
The only reason I used a headphone jack was because it was the only connector I had on hand at the time. The final production version should have the standard micro connector. The new PCB designs will incorporate all those standard features.
Solderdoodle cools fast when cleaning the tip on a wet sponge, so it does need full-on power to recover and work consistently. It is all controlled with a high-quality charge control circuit that has an over-temperature switch that activates if the circuit goes over 120ºC.
Yes, the BP645 tip that is currently being used is replaceable. The production version may include other brands depending on which supplier can sell the heating elements off-the-shelf easily:
If a custom heating element needs to be designed, we will explore that option too.
