Tachyscope 1.0                                                              June 2023

In this Blog I will go through the complete build process of my Persistence Of Vision project I called " TACHYSCOPE"

To begin with, Tachyscope was an early animated-picture machine circa 1880, refer to Google for image of it.

My version is a two channel SERIAL led display unit. 

An earlier prototype can be seen here at

 HACKADAY.IO,     link here   https://hackaday.io/project/190143-dual-channel-pov-display

 INSTRUCTABLES.com link here  https://www.instructables.com/DUAL-Channel-SERIAL-POV-Display/

 

My Final version can be seen here at

Lets get started 

What it looks like


Below is the FRONT view

The aluminum "pan" holds the DUAL led displays on a rotating spindle ( circular PCB) as well as 4 selector switches ( black Knobs). The selector switches determine the source data to be displayed on either  the front BLUE or the rear WHITE displays, Displays are inserted into a glass test tube, 8 SMT leds mounted in a vertical line and a 9th colored led as a marker indicator.

On the right 1/2 there are 4 more function switches  "Knobs" relating to the NIXIE displays, The left Nixie displays, Temperature in Celsius and Fahrenheit then Humidity, cycles them 1 at a time.

The right NIXIES display a series of functions determined by a multi-position switch. Can display voltage, blinking counter, Up counter, Time clock , and finally RPM of the spinner POV.

Victorian Teletype AKA SteamPunk themed

 This is a short intro to my TTY Teletype project ( addition)  to my Cosmac Elf 1802 family. Here is a YouTube link to the INTRO video, 2:23 mins in duration. https://www.youtube.com/watch?v=n57a-BLW3nY&ab_channel=DanielRoss The finer details...The No7 as I received it.. DOA. Donor # 1 typewriter,  A Remington No7, circa 1900, this one was rusty and covered in soot, must have been involved in a fire at some time, possibly hosed down, the wood bits where staring to rot. Donor # 2 typewriter, A Sharp PA-3000 from 1990s, daisywheel print, no display, limited character buffer memory. Mashup result, ( not fully completed) as you can see the keyboard is 1/2 there. The blinking lights on the keytops reflect what character, digit is been printed by either the computer or the operator, also shown in the display. Below is a test during the build, I'm using the  electronic Typewriter keyboard and adjusting the travel on the carriage platen.   Another test example,...

My Cosmac 1802 build

Image
 Back in 1976 Popular  Electronics published an article about an RCA CPU called CDP1802, COSMAC ELF. This was to be the entry point to computers for me. Had fun building it on a perf board and point to point wire soldering.   Below my collection of  "1802 bibles". Each one of these magazines had 1802 projects/ programs/ or  schematics. Fast forward some 4 decades and now I'm re-visiting that humble little computer and super sizing it a bit. Here is my latest incarnation the Steam Punked  COSMAC VIP - ELF project.   What is it?  Its made up of  5 parts, The MAIN cabinet, The Glass TUBE Display, The BCD-HEX keyboard, The ROTARY HEX keyboard and Audio Speaker (horn), and finally the VIDEO CRT display unit. The main electronics are made up of  custom made PCB 4" x 4" stacked on a 5" x 10" motherboard. They are located in the MAIN cabinet, ( the unit with the 8 blue 7 segment VFD displays). Above are the main ELECTRONICS located in the cabin...
