<P>요즘 흐르는 세월이 유수같이 빨리도 지나가길래 얼마나 빠른가하고 측정하고저 FC를 만들어 봤습니다 ㅋㅋ</P>
<P>원칩 마이크로 프로세스인 PIC16F877A 을 사용하여 부가장치없이 바로 입력단에 인가하여 무려 50MHZ를 카바하게 되었습니다 보시다 시피 아주 간단하게 구성되었고 정확도가 아주 좋습니다 </P>
<P>그간 배운 케드로 직접 아트윅하여 PCB기판을 만들었습니다 그것도 grounding pattern<공통어스채우기>로</P>
<P>고주파에 용이하고 노이즈에 강하겠지요 .. </P>
<P>여기 회로도및 소스 첨부합니다 ..</P>
<P>특히 고주파 <라디오>가지고 놀분은 한대쯤 만들어 놓으면 쓸모가 많겠지요 </P>

첫댓글 기판 제작을 직접 레터링을 이용하여 애칭 하신 것 같습니다. 저도 한때는 열심히 기판 제작을 하였었는데 이젠 엄두가 나질 않는군요. 자작의 진수를 보는 것 같습니다.
진정한 자작파이십니다.~~
자작으로 50Mhz 이상 FC 만드는일 흔치 않습니다~역시 ! 좋은기능 나타내는군요~ 바람한점 없는 뜨거운 여름날 만드시느라 수고 많았어요...짝 ! 짝 ! 짝 !
멋진 작품하나 만들었군요. 이번에는 mfj 같이 만들기를 희망합니다.
