Intel 8008 Information

For anyone interested... Here is some documentation I have gathered on the Intel 8008 microprocessor. The project to implement a functioning 8008 computer currently stands at level 26, in my queue of things I'd like to build. In this Dropbox folder you will find: 8008 User Manual 8008 Data Sheet Cutting from "The Intel 8008…

WiFi Camera

I am closing on the completion of a "contract" to create a set of three WiFi camera enclosures. The electronics consist of a Raspberry Pi Zero W, and a Pi Camera with IR LEDs. The 3D printed parts were to provide a protective enclosure for the camera and to attach the Raspberry Pi to a…

Robot Shop/ Infrastructure

So... I can't seem to get a way from it. Therefore I will formalize it. Kinda like an "Undocumented Feature." While robot development is moving forward, it does so ever so slowly. Partially due to work in building up the "shop." Over the past months I have been acquiring lab equipment and materials. Some donated…

And life goes on… (and UPS)

Well it seems that life (and all its marvelous flavours, fluctuations, and failures) will just. Not. Go. Away. While my endeavours in robotics have not ceased, they have taken somewhat of a backseat to some of my other investigations. This realization has led to my decision to expand this blog (term?) to cover these other…

Back from life

It's been a long nine months, since my last post. As it's known to, life has gotten in the way. On the robotics side, it's not been totally unproductive. I've done a major reshape of the process flow and redefined the individual processors' jobs. Partially due to understanding of the capabilities of the processors, but…

Inter-Processor Comms

Below please find links to information on using I2C and SPI to communicate between Arduinos and RPis. There are others and I'll post as able.

Get to Git

In preparation to dig deep into programming Rover II, I decided to implement a popular content management system (Git). The concept is simple (Track changes to your code and be able to back out a change if it breaks every thing). It also enable you to share and collaborate on code development. I was luck…

Rover II – Admin Console

Admin console is wired up and programmed, with the help of Adafruit directions. Hopefully this will be the last of the Python programming. I hope to complete the Raspberry Pi coding in C++. Maybe I'll have some time to go back later and re-write enough of the BC library to implement the LCD in C++…

Rover II – Power & Control

Made some more progress this week with building up the administration panel and power management system. I still have a great deal of wiring to complete, but at least I have things to wire to. One neat little addition is the Adafruit Trinket that sits on the power management board. It's a little 5 port…

Rover II – Stop-ability

And there you have it. A bumper. Works fine. Next steps; wire up the Arduino to the motors, encoders, & bumper switches, and migrate Rover I's code from two wheel to four wheel.
