This log includes major upgrades included in the current system.Till now we had been using an older OS incompatible with RPi 3 since the display could have only worked with that image. Additionally it caused the trouble where the onboard or external...
Earlier version of the device was reconsidered in terms of following aspects:• Accommodating for different refractive errors • Aesthetics • Ergonomics • Weight distribution OIO ASSEMBLY EXPLODED ASSEMBLY1. ACCOMMODATING FOR DIFFERENT REFRACTIVE ERRORS...
7/29/2013: As I stated; been working on the cabinet for the Mirror universe project. I bought a couple of "project" Bally Star Treks from a fellow pinball collector out of Shertz a few years ago. These have been setting in storage for a while... and...
During the initial design stages of the SpiroBot, the issue came up of how the robotic "arm" was to hold the pen. Our particular design required that the pen be able to move vertically to adjust to small irregularities in the height of the platform and...
I've added a small Z-axis out of an old DVD-Drive and hoocked it uf to my CNC. At the z-axis i mounted a pen, so now my machine can plot pictures on a Paper or flat surfaces like my "Sprit" or alcohol bottle.
the first two prototype was just figuring out the frame and kinematics . I didnt want the the pen to have any kind of ugly wires hanging outside which would be the case had i used a normal solenoid or a servo to lift the pen. To avoid that i used a h-bot...
Many people who have aphasia cannot grip a tiny pencil. A common adaptation to a pen, pencil, or artist's paintbrush is to fatten it up to make it easier to grip. This 40mm x 150mm cylinder has a 9mm hole in the middle to hold a standard "Bic" pen. It...
I got myself a nice little linear rail from smalltec.de for 50 bucks: This will now serve as the z-axis and also provide suspension so that the pen will have more or less constant pressure on the paper. The parts for attaching all the stuff were made...
After usual wait of one month I got pen adapter ordered on Aliexpress:I chose this model because one can change tip position by screwing in or out part with cylindrical protrusion. This gives some versatility, but also creates a few challenges. First...
Summary about 4:00 pm, Monday, January 21, 2019 Soldering stuff together. Out of fear of destruction, this was done in steps, testing along the way. Deets First, the NodeMCU board has pin headers soldered on (or at least mine do). These aren't...
I finally make it working (at least on Windows 10). I already committed to my GitHub, so the latest code is now working! Also, I'm now understanding the way to report the correct hid event, so let me guide through. the number in parentheses corresponding...
SHOULDER and ELBOW The 2 main articulations (shoulder and elbow) are equipped with stepper motors. The transmission uses toothed belts and their pulleys. These 2 articulations are very rigid. They are made with 3mm aluminium sheet, and braces made with...
We are part of Wimbledon Art Fair this weekend, and the plotter (which I have named "Picoplot" for the sake of having a title!) is hanging just inside the studio door, as a nice way to draw folks in. Blinky lights and moving robots! I've painted...
I am currently a little bit obsessed with making the construction as simple as possible.I figured to draw up some sketches and plan out how the parts and functions will be like.This is the sketch for the corner bracket(???) thing at the four corners,...
