Small Details Matter.

Nice one William, but it could have been a bit more user-friendly. I know you made it for your own use, but if someone else in your home has to use it, they will be confused about it, like i was while watching the video. The reset button should have been a separate button instead of holding two buttons simultaneously and the buttons are also not self-explanatory.
It's a great device you made, but adding these small details to it will enhance its use.

Daniyal you are right about keeping small details in mind for a better device, but we cant  take credit from the product as it ia an amateur s attempt. Good work . keep developing.

I agree. But I believe the unit he built was a proof of concept, therefore the product was rapidly prototyped. I like the concept of repurposing old electronics by enhancing them with with current or advance technology. Nice work William!

PIC16F Assembly Language Source files

Noticed you wrote the code in PIC16F Assembly Language. Was wondering why this programming language as to using C? Also, where will one gain access to the assembly code source file for the project?

Detail Circuit Schematic Diagram

In reviewing the build document, I was wondering if you have a detail circuit schematic diagram showing the 4 digit 7 Segment LED display with actual pin numbers on it. I understand the display used is based on the hobbyists preference but showing your example as wiring template will help others to build their gadget successfully.

I agree mrdon. It is indeed a good prototype and i am not taking any credit away from him. I was just trying to guide him for his future endeavors so that his next prototypes are even better for him and for the rest of us. Even the great inventors in today's fast developing world sometimes ignore the small details which can make the difference between them and their competitors. If we get into the habit of paying attention to our small and rapid prototypes early in our lives, we can create beautiful products as we move forward.

I understand your points about getting  into the practice of insuring the small details are captured during a rapid prototyping phase. I stress this with both my adult and high school students I teaach in electrical/electronics and robotics technology. My books have the same philosophy as well. Therefore, you and I are definitely on the same page. Just curious, what type of products are you currently developing?

I agree paying attention to minor details for future improvement is necessary.

I guess if you don't play billiards, you don't know what the gadget does. The ASM code has almost no comments in it, making it extremely difficult for someone else to figure out what the code is doing.

You'll notice in my GF projects that when I use a PIC microcontroller, the ASM code is heavily commented. Without the comments, even I would forget how the code works after a year or two.

Other than that, I think it's a nice project. I certainly appreciate the engineering talent that went into making it. Just please comment your code, so that the rest of us can learn from it.

D_A, really it is better to have the reset function use two buttons since that is a good way to prevent an accidental rest, which I have done with other equipment on a few occasions. So I would vote that the two button reset is a good choice.

I would also offer that the box did not need a PIC processor to deliver that functionality. The CD4510 is a handy up/down counter that needs no programming, and just by examining the circuit diagram the function is quite obvious. Plus it is a chip that will be around for a few more years, unlike the cute little micro chips that become obsolete a year after release, and are mostly single sourced. One can be hurt quite badly by using single sourced parts, I know first hand about that.
