SHAOS

I got one PIC32 in DIP

It’s time to learn MIPS opcodes

If you want to play with TRIMUX for free then just e-mail me request for a free sample (1 pcb per 1 person or address):

TRIMUX may be used as memory element:

or as buffer and inverter:

To test TRIMUXes we may use 17-rows breadboards:

1K resistors may be removed for faster operations (1 MHz instead … Continue Reading

1st application of TRIMUX devices – ternary-half adder:

Now you can buy TRIMUX PCB to create real ternary hardware (including ternary computer)!

It is dual ternary multiplexer board – $13 for each PCB (plus $10 handling and plus shipping):

Another page about building binary circuits with memory based on 74F00:

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

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

Now I’m thinking about building binary circuits based on 74F00:

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

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).

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
