From Maker’s Box on Tindie, a 3D printed drawing robot you can build, program, and modify:
At Hackaday, we’re constantly impressed by the skill and technique that goes into soldering up some homebrew creations. We’re not just talking about hand-soldering 80-pin QFNs without a stencil, either: there are people building charlieplexed LED arrays out of bare copper wire, and using Kynar wire for mechanical stability. There are some very, very talented people out there, and they all work in the medium of wire, heat, and flux.
At this year’s DEF CON, we opened the floodgates to competitive soldering. Along with [Bunny] from Hardware Hacking Village and the many volunteers from the HHV and Soldering Skills Village, dozens competed to solder up a tiny kit full of LEDs and microscopic resistors.
The kit in question was an SMD Challenge Kit put together my MakersBox, and consisted of a small PCB, an SOIC-8 ATtiny, and a LED and resistor for 1206, 0805, 0603, 0402, and 0201 sizes. The contest is done in rounds. Six challengers compete at a time, and everyone is given 35 minutes to complete the kit.

From Cynthia Huang on the Tindie blog:
Tindie has been a favorite platform for creative makers for quite some time now. Hundreds of thousands of hardware craftsmen, hackers, and enthusiasts gather here, share their ideas and create a lot of amazing products.
Three years ago Tindie published an article that used the tools of data science to look at what makes a product successful. It’s been a very popular article, providing insight to the inventors who build their communities of customers through Tindie. With so many new products and sellers since the previous article, we were inspired to dig into the numbers once again to determine if the criteria for selling a successful product on Tindie has changed over the years.
From Bradley Ramsey on the Tindie blog:
When you take your first steps on the road to becoming a maker, one of the first skills you’ll need to master is soldering. It’s the backbone of just about every electronics project, but it’s not an easy skill to master. Don’t let the fear stop you, soldering opens up a lot of DIY projects for you.
With the I Can Solder Badge, you’ll not only learn the basics, but you’ll also have proof to show the world. This badge project is unique in that it also teaches you about circuits and includes a switch to save the battery power.
Included in the kit is a purple PCB manufactured in the USA by OSH Park, an RGB LED, a resistor, a switch, and a battery holder for the CR2032. Keep in mind that you’ll need to purchase the battery yourself as it cannot be mailed out with the kit due to USPS guidelines.

The Robotics Module Challenge just wrapped up and last week we featured two of the twenty finalists who are also Tindie Sellers. Today let’s look at several other Tindie Sellers who got in the game with their own robotics module designs!
Tindie seller Citrus CNC Store is working on a low-cost automatic pick and place feeder and entered it into the robotics challenge. The pick and place machine is a valuable resource for building electronics.
The end goal here is to create a fully featured pick and place machine at a mid-range hobby 3D printer price point, with support for at least 20 automatic tape feeders and loop control of every motion related component. Check out this project on Hackaday.io.
Another Tindie seller who owns the proto-Phi Store is working on a modular design for a soft robotic gripper.
The design is for soft robotics fabrication and emphasizes the molds and subsequent actuators. The current method combines the softness of a silicone actuator and a 3D plastic exoskeleton.
