IR location not locating
Log from Swarmesh NYU Shanghai
We started to assemble the infrared relative location circuits but it took us more than hours for the first two pieces. We spent other four hours to test their functions, finding many issues that were conflicting with the design. It was critical to our...

Log from The Digi-Gurdy and Digi[Nerdy]Gurdy
Many improvements to the code. - Strange extra click sounds all removed. Generally smoother sound.- Buzz sound is now at same pitch as the (virtual) trompette string.- 2 melody strings one octave apart.- 2 screen display options: Original with notes...

Cycloidal Drive
Log from 3D Printed Robot Joint with Active Compliance
Before reading anything else, go and checkout this excellent project by Paul Gould. His work was very inspriational. In fact, before stumbling on this I'd never heard of a Cycloidal Drive. I'd been looking for a way to rework my stalled robot arm project...

Progress in defining the PnP aluminum head
Log from Fox.Build PNP
We decided to tackle the most undefined portion of the project. The files for the laser cut wooden pick and place head were in the repo but all the final pictures had the aluminum head. Of course that meant we had to find a way to start in aluminum....

PCB Layout
Log from OpenHAP
We obtained the following aluminum profile(Code REH8253) from a chinese manufacturer www.robustcasing.com: Due to the sliding action and play within the enclosure, the copper was pulled back from the board edge to accommodate this movement. PCB...

Motor controller PCBs
Log from BLDC Walker
Finally the PCBs have arrived. I guess I imagined them a bit bigger, as I was surprised by how small they really are. The outline is just 33x33mm, so I will be able to fit it behind almost any of my smaller BLDC motors. Since I last wrote I've been working...

How I designed the Blackbox
Log from Multitool 3D Printer - Blackbox
As an Industrial designer, I probably got a different approach than other RepRap contributors, which are often mechanical or electrical engineers. With this log, I want to communicate how decisions are made from a designers perspective. Complexity and...

Mechanical design (part 2)
Log from Build your own TurtleBot 3 backbone
First Layer Switches holder I use two switches, one to power the SBC and another one to power motor. They come with they respective LED that indicates which device is on. The plate that hold them also serves as spacer to support the upper plate. A symmetrical...

Improvements for version 2
Log from Upright Laser Harp
The upright laser harp has been a successful first prototype, but there are a few parts of the design that make it difficult and time consuming to construct. My ultimate goal is to make the upright laser harp into a robust kit. I have the design plans...

Full-Metal Roving
Log from "Tenacity": Yet-Another-Sawppy-Project
I got these in the mail the other day:Sawppy builders will recognize these as the triangular wheel hubs used to mount the wheels to the drive shafts of the motor pods. My buddy Ed "Steamboat" Haas and I have been collaborating on replacing the 3D-printed...

End of year State of the Book
Log from The Open Book Feather
Some quick notes on The Open Book at end of year. First: after a lot of people asked about donations, I made a Patreon page where folks can support the work. But whatever, on to the work itself: rev 4 was a success! The new features (mic shutdown,...

Focus stacking (kinda)
Log from LadyBug BEEFY: 3D printer motorized microscope
Team member Yujie is quarantined, too. This has left him weak and prone to suggestions, like "instead of doing your homework, can you implement this very specific form of focus stacking to prove a point about focus stacking?". Say you have a lumpy...

Adding Movement
Log from Nova - A Companion Bot
The most important part of this project, and new skill for me, was creating natural and whimsical movements. One of the most compelling things about the companion bots I have interacted with is their randomized movements that begin to feel like...

Rotating Axis 1
Log from Camera slide
The rotating axis for the camera is in progress. The junk pile was full of steppers, but only had one decent reducer. The gears meshing has a little backlash in it, but I am curious to see if it will work for the end effect of the video. ...

PCIe Fun, and the PT NIC has arrived
Log from pfSense Router/Firewall Install
20200219 - Tuesday From now on I'm going to refer to the NICs by their most obvious identifier for two reasons: It's shorterI'm probably returning the original, but would like to easily be able to refer to either. I'll refer to the original as PT. I'll...
