Experiments continue on the 2020 Bot! The robot on the left was built using the ubiquitous 28BYJ-48 geared stepper motors and ULN2003 drivers. The robot on the right uses the famous yellow gearboxes plus brush motors with an L9110S dual motor driver board. Which one should I use for the 2020 Bot? Continue reading

Maker Faire Shenzhen 2016
Here’s a somewhat long slideshow of photos from Maker Faire Shenzhen. I decided to skip World Maker Faire (NY) this year and instead go back to China. The trip was really short, fly 16+ hours, arrive Thursday night, attend Maker Faire Friday, Saturday, and Sunday, then fly home 16+ hours on Monday. Typhoon Haima didn’t really think that was a good plan, and decided to hit the Shenzhen area mid-day Friday. The organizers of Maker Faire postponed the whole event to Sunday and Monday, and scrambled to take down all the outdoor structures Friday morning. Fortunately, the typhoon wasn’t a direct hit, and while it was very windy and rainy, the area was spared a major impact. Faire organizers reassembled the event during Saturday, and opened up on Sunday. As for my visit, well, I’m glad I had at least one day at the Faire! The bright side to the whole trip was that I spent quality time with some really great maker/hacker people in Shenzhen.
NRB – Robot Networking: Socket.io and the ESP8266

Introducing the EB1
Well, the EB1 has actually been around a while. It’s the brain child of Tully from Samurai Circuits. A few years back he tried to convince me to work on an inexpensive Arduino compatible platform that could be used for teaching electronics and programming, but without needing a lot of extra pieces (like a breadboard, power supply, USB cables, etc.).

These are the slides from an ESP8266 presentation I gave at a Nashua Robot Builders meeting.
NRB – Robot Kit Presentation
This is a short presentation about robot kits I gave at a Nashua Robot Builders meeting.
Cheap Robots
To get started with off the shelf robotic kits, there seems to be a price threshold of about $50 for a bare bones ugly hack-kit.
