Evaluating the Unusual and Innovative Perf+ Protoboard

Posted on by

Back in 2015 [Ben Wang] attempted to re-invent the protoboard with the Perf+. Not long afterward, some improvements (more convenient hole size and better solder mask among others) yielded an updated version which I purchased. It’s an interesting concept and after making my first board with it here are my thoughts on what it does well, what it’s like to use, and what place it might have in a workshop.

Perf+ Overview

The Perf+ is two-sided perfboard with a twist. In the image to the left, each column of individual holes has a bus running alongside. Each hole can selectively …read more

Colorful Fan and LED Controller for 3D Printer

Posted on by

[Dave] just couldn’t take the ambient noise from his Lulzbot Mini anymore, so he built a fancy fan controller for it.

He measured some points on the printer’s Rambo controller board to see what actually got hot during a print. The hottest components were the motor drivers, so he taped a thermistor to them. He also placed one in the printer’s power supply. He replaced the main fan with a low noise model from Noctua (which have the most insanely fancy packaging you could imagine for a computer fan). The software on an Arduino Nano now idles the fan at …read more

The Raspberry Pi Zero Contest presented by Adafruit and Hackaday came to a close last week, as the clock struck 11:59 am on Sunday, March 13, 2016. Since then our team of judges has been working to pick the top three entries. It was a hard job sorting through nearly 150 amazing creations.  In the end though, the judges were able to pick three grand prize winners.

Hackaday Links: March 6, 2016

There’s the R2 Builders Club, hundreds of people are building BB-8, but there are a few robots that don’t get enough love from the amateur propsmiths. [Kenneth] just finished up his build of Crow from MST3K. He built Tom Servo a year or so ago and K-9 from Doctor Who. The beautiful thing about building MST3K robots and Doctor Who props is that you’re probably working with a larger budget than the prop department had.

Heathkit’s new website is up. The two products we know about so far – an AM radio kit and a slim jim antenna – can …read more
