74ls163 Clock Counter Project|Atanua


PictureA while back I posted a blog about the 74ls163 Synchronous Counter. In this blog I will revisit the same TTL using Atanua software. After playing with the 73ls163 I gained a little more insight about it. 

I found that (referring to the diagram) by changing the input values you can program the count up starting number. This TTL can only count up! To do this you will use input switches 1-4
Switch A is used to clear the counter and pin 2 is for clock connection. The "Ripple carry output" (RCO) used to enable successive cascaded stages. *floating pin in the diagram.

After setting your desired starting number, you can enable P, T & Load to start the count. You will see your project initiate from the programmed value. However, to keep the clock in a loop additional TTL's must be added; the 4 input Nand & Invertors. A nice project write up can be found here:

DesignSpark|PCB Settings








First you will need to start with a new PCB Design. You are able to specify how many layers your board requires and if you will start with a circle board. The file should open with a square PCB by default. To erase the pcb press the Select Mode icon (second to the last: arrow icon) select the pcb and press delete on your keyboard or click the red X icon.
Now you can proceed with your new pcb shapes. To do this, on your tab bar go to ADD: scroll down to Board and select any shape. You are now able to make your desired board shape. Try a few different ones. Next option to choose is changing the colors of the pcb, components, traces, silkscreen, and pins. There are 48 standard colors to choose from and also a color palette option!
As you can see DesignSpark allows you to design many pcbs in one work space. However, selected pcb settings will apply to all boards within the work space.

DesignSpark: 3D Modeling Software Review


DesignSpark PCB Review                                                            
By: Larsha Johnson

When it comes to PCB/3D modeling there is a plethora of software to choose from, such as Altium, DipTrace. PCB 3D, Target 3001, NI Ultiboard, DesignSpark and more! For those of you who have read my previous blogs you'll know the past circuit designs were created using NI Utliboard. In this blog I ventured out into the world wide web for more 3D rendering software options.DesignSpark is what I found and here are my results.

What I like about DesignSpark so far (an hour in) is that there was no cost! I simply downloaded the software and was able to jump right in. However, the downside is that you are required to create an account to use it. Coming from NI Ultiboard to DesignSpark I was very knowledgeable about how the user interface worked. I will admit I watched one YouTube tutorial to get things moving. 

I soon found myself designing (placing a few random components if you will) my very first circuit. The purpose was simple, test the user friendliness of other 3D software. Overall I will say that DesignSpark is definitely easy to use. And the components look amazing.

There is one feature that I liked the most in this pcb 3D software and that is the option to change the color of the board. Join us next week for an update on colorful pcbs.
