Yesterday I put the final touches on the wooden case. Everything has come together wonderfully, and just under 6 months of work has paid off:---------- more ----------I have made a video demonstrating some of the features. It is a bit long (about 9 minutes),...
This week we took BowlerStudio on the road. We taught a class of 15 students ages 9-14 years old, kids programming. We went through variables and functions by making calls to JCSG. The students made each step in their own Github Gist, so that have a...
Designing for this project required many different approaches. Sometimes it was easy enough to take measurements, design the part in question and make it according to those dimensions. Other times it would be exceedingly difficult to measure all aspects...
So I finished the schematic. I have implemented:Raspberry Pi ZeroAnalog audio outTeensy LC Capacitive touch interfaceWS2812 wakeup lightESP12-E for internetUSB Hub (mainly backup)MPU9150 9 DOF IMUI removed the audio amplifier. There are a lot of cheap/good...
So, I split my Sketchup file into a couple STLs, then imported them into XYZware.When I went to print the rails/corners/connectors in the previous log, my printer went BONKERS!!6 attempts and cleanings and still getting bird's nests. Tried different...
Finished modeling the two axis motors today and came up with a first pass at the motor to slide holder interface. It's not pretty but it should get the job done, assuming it isn't too much friction for the tiny Y-axis motor to handle. I'll print these...
I finished the main functionality for the scope last week and took to the University of Alberta Engineering DiscoverE camp for a demo. It was the main, end demo for a little talk I gave a grade 7-9 "Awesome Arduino" campers on the idea of "software-enabled...
Here's a realistic 3D printable case idea. Larger than I want for a final design, it will be sufficient for a prototype.It's 4.6" W X 6.2" H X 1.25" D. It would use 3D printed keys as well.There's still a lot of mechanical design that will have to be...
What's up guys!It's midnight here and I just launched the Indiegogo campaign for my shield. Check it out here and be sure to share the link on social media because every view counts for me! Contributions are also greatly appreciated and will help me...
I've been building the GTXL one step at a time and checking as I go. So far, the power system, clock, program counter, IR/D registers, and control system is working. I made one mistake with the diodes. The artwork is reversed, so I installed...
Recently required a USB keyboard, so I had to update the PCB (v5) in order to work with the nrf52840 Feather Express. The idea was to enable hot-switching from bluetooth to USB automatically when connected via USB, and back to bluetooth...
I've been fairly busy at work (as in the job that pays the bills) but I ordered a knob for my lerdge X and soldered it in. Lerdge X and K pin mappings seem to be right, though since I'm not remotely using all the functions I can't be certain everything...
Just ordered some components from US suppliers, so they should get here fast:10 x 3Pin 10cm Servo Extension Lead Wire for Futaba RC Connector Cable LB10Pcs 2.54mm Pitch 0.1 1x15 15 Pin 15p Female Dupont Header Arduino Nano HeadersAnd then when those...
Hot off the press... Routing was just completed using 8 mil traces with 7 mil spacing. This was 100% hand routed and took about 30 hours. The original attempt using 10 mil traces with 8 mil spacing failed after about 24 hours of work. The ability to...
