My hardware design described earlier has been proven to be working:

DG403: two chips - no more components

Today two DG403s, four chip-capacitors 0.022 uF and 15-pin header were composed by me to the dual ternary multiplexer TRI41D:

1st test of TRI41D

TRI41D pins description:
1. S – select command (choose pins to connect)
2. N1 – connected to C1 if S=”N” (negative)
3. O1 – connected to C1 if S=”O” (ground)
4. … Continue Reading

Explanation of idea about ternary hardware based on DG403 switches and also attempt to apply the same approach to 4-value logic:

DG403: one chip with resistors

Here I use undocumented feature of DG403 when normally closed switch opened by voltage lower than required to close another (normally opened) switch. Variable resistor is used to move that “both-opened” window to ternary “0″ zone (up from -3.0V…-0.8V to cover 0V).

DG403: two chips - no more components

Second scheme is more “correct” (nothing from undocumented features were used).

P.S. Ternary selector may be used as ternary inverter when RP=-5V, RO=0V, RN=+5V. … Continue Reading

Another portion – now about extension of 3niti alpha simu1 board:

Way to convert Morse code to balanced ternary code and back:

Today I created second test for my quasi-ternary board – it is a ternary clock:More about board is here

Today I did real test of this board with simple test program inside pic16f870 that reads “ternary” input (15 3-position slide switches) and sends it to “ternary” output (15 red-green LEDs):See details about this board here

If you are interested in ternary computing check open source Java emulator of my ternary computer 3niti alpha:http://ternary.info/ternary/java.php?applet=3

I found great resource about creation of simple ternary computer:http://jeff.tk/wiki/TrinaryThey started at November 2007, but they have built a few ternary modules already!P.S. On January 2009 I found out that they changed port number for their web-site, so newlink to them is:http://jeff.tk:81/wiki/TrinaryBut unfortunately nothing was updated over there for a long time…

I created new web-site about open source ternary computer – www.3niti.org.I hope it will have emulator soon. Then I will try to build REAL ternary computer…
