16F628A microchip question

Ok. 1st of alI I am brand new to electronics and do not know much at all but I am interested in learning. I want to build a 2 segment counter and found a circuit but it uses the microchip in the question. I was wondering if these chips come pre-programmed to count or does it have to be programmed? Thank you.

which chemical to deactivate microchips? Answered

Hi, I'm making a cryptex, such a thing like in the Da Vinci Code, and I'm going to make an Instructable of it later. But I'm going to hold USB-sticks in it instead of a piece of paper. That's a little more modern nowadays people lose a lot of usb sticks with secret important information so I'll use a cryptex for it. The crpytex like it was invented by Da Vinci contained a paper, which was rolled around a tube with vinegar in it. If someone decided to just smash the cryptex, the tube breaks and the vinegar would destroy the ink on the paper, making it unreadable. I don't think that works good in real but I don't think it will deactivate a usb stick either. So I want something else in the tube that DOES eat the chip. So I'll remove the outside wrapping of the USB-stick. What fluid can I use?

What does this chip actually do? Answered

Its labeled MACH210-15JC-18JI I've looked over the data sheet, and it says: 44 Pins 64 Macrocells Peripheral Component Interconnect (PCI) compliant 32 Outputs 64 Flip-flops; 2 clock choices 4 “PAL22V16” blocks with buried macrocells So, it holds data bits with flip flops? In the specs it says D or T type flip flop. Its programmable, but what does it mean by that, how would you "program it" it has 44 pins, and some I/O. What do you think the applications of it are? I have the pinout, but that doesn't really do any good if I can't figure out how to "program it"... It can run at 133MHz tops, but if this was memory there would need to be a section that says when to read/write on rising or falling edge of said clock. It doesn't say that. EDIT: So.. what does High-Density EE CMOS Programmable Logic mean? Sorry for the questions lately, just trying to figure stuff out

How Do these work? What is the difference between microcontroller and microchip ( are they the same thing? ) Answered

Well I have been opening things like VHS, DVD players Computers and a lot of other things ( since my family is not the richest around we usually buy stuff second hand ) But even if we did get new stuff I would probably be the same. I am a curious kid by nature ( it must be a hundred times i heard the line curiosity killed the cat from teachers to even my family and friends ) Ok so to the question What are these microchips/controllers What ever they are. Like how could I use one if I would be able to get them out of the circuit? I heard they get programed to do something. How do i program one? Why do the circuit always so complicated?

Custom PIC

Savage innovations does not offer a small OOPic chip. OOPic is my favorite MCU and I want a small one. Soooo, I decided I want to make one. In theory, The process is simple. The OOPic 2 is a PIC16F77 with custom firmware. I ordered a similar chip (PIC16F876A) to put the firmware on so I basically have a smaller OOPic. Savage innovations does not offer the OOPic firmware as a download so I have to extract it from my OOPic2. Here's my questions. Will a JDM2 programmer be able to extract the firmware? Will WinPic800 work to do this? Will this erase my OOPic's firmware entirely? Is it even possible? I would like some input and if you guys say it will be okay, I am going to do it. (I'll post and ible if it works.

Mass production and led's and arduinos?

I'm interested in making something that will have several led's that I would like to flash randomly and some flashing slowly, some fast, etc.. Some with the "fade in/ fade out" kinda deal (sorry, don't know the terminology). Anyway, I'm in the process of learning all about the arduino and I'm just beginning. What I would like to know is, say I figure out how to make these led's do what I need them to and I make up one "unit" and I put it all together etc.; will I have to buy and use an arduino for every single one of these? That would get very expensive. It's kinda like those pictures I've been seeing lately for Halloween/ fall/ Christmas that have led's flashing at different times, and some come on slowly, and then fade out slowly etc.. Or anything really maybe like those little rubber balls that have flashing led's in them. How do they accomplish this? Do each of those pictures have an arduino in them or is it a matter of "programming" some kind of cheaper "chip" and using it in each project? Like I said before, I don't know the terminololgy. Just looking for most economical way of accomplishing this on several different projects. Thanks so much for any help from anyone!!

Arduino Coders: Idea for an instructible

I tried building this Performance Monitor project that uses a PIC device.  http://www.waitingforfriday.com/index.php/USB_Performance_Monitor The project is 4-5 years old, and Microchip has made changes to compilers and the MPLAB IDE that break the code in this project, and the maker has expressed that he is not interested in updating his old projects.  He has since switched to AVR processors for new projects because of the difficulties with the Microchip compilers and IDEs. For me, fixing his project or making a similar project for Arduino is beyond my newbie coding skills.  For someone with skills in this area, making an Arduino version of this project might make a good I'ble.
