My Projects, PCBs, and Designs and play time

By: Engr. Firas Faham

The following images are some of my projects and designs I worked on, I haven't had the chance to include everything I designed and worked on due to time availability and convenience. Please do not copy any of these images without my permission. If you have any question or need any technical assistance email me at fifaham@yahoo.com

14. I run out of bookshelves.

15. Still have over 200+ of them on floor.

16. But have no time to buy book shelves.

17. I designed this wireless system for reporting and monitoring purposes.

18. This wireless system I designed works with the wireless system of item 17.

19. One more security board I redesigned, but can't disclose whom I designed it for and what it does.

20. A hygiene system I designed around a water tap! I can't disclose more than that.

21. I designed this On Screen Display (OSD) so it can display an overlay text on your NTSC TV.

22. Don’t touch this high voltage stuff. My house electric main panel. Something I like to play with.

23. My busy hours with these nice creatures.

24. They just look wonderful.

25. Such a beauty.

26. Tons of electronics parts.

28. This is a wireless system that I designed to ignite a firework by remote control so children can use it to play safe with fireworks. Go to the top ^

29. This is a very powerful development tool by Free Scale I used to develop around Microcontrollers.

30. I designed this board to demonstrate firmware of various projects I did. Status of circuit is displayed at the LCD at any time.

31. I designed this large display to use with electronic banners and public reminders. It is basically composed of decade counter, BCD to SSDD, and is controlled by the Microcontroller.

32. Look at these thousands of lovely IC chips.

33. My life partner art lab.

34. This is one of the audio amplifiers that I designed for use with many of my projects.

35. I used this dev board to develop many of my prototypes and designs. Very handy and powerful.

36. This is one of the Eval-Boards I used to develop my own switcher power supplies.

  37. I made special modification to the pager so I can control any device from the telephone.

41. Very powerful and versatile wireless high-speed transceiver that I used to control various instruments via the microcontroller based designs.

42. Regenerative wireless receiver that I used in so many wireless projects to control may house equipment and appliances.

 43. This is a wireless transmitter the size of your finger tips. So tiny that it can fit almost anywhere. I used it to transmit control signals for various controls.

44. I designed this circuit to use with the RS232 computer port so I can control things from my computer.

45. Here again. Different flavor of regenerative wireless receiver I used to control various devices via my computer wirelessly.

46. Very nice board to send wireless signals via my computer to control many things. I wrote a GUI VB program that does many wireless controls such as wireless door lock, monitoring, and camera manipulation.

47. This is a $5 toy I tortured to use its RF receiver to embed inside anything that is small in size. Not very reliable but it works!

48. I used this wireless reviver with the above transmitter, item # 27 above.

49, Ethernet board I am using to control things via the internet.

50. This is a fly back transformer (left) I pulled out from an old TV so I can use it to generate high voltages. The high voltage cap on the right side.

51. This is a keypad I used to design a password and control entry system for a security system.

52. I used this board to design another security board.

53. One of my favorite 2 by 16 LCD. Can be used as 4 or 8 data pins. I used in many of my designs.

54. This is a 27 MHz wireless transmitter that I used for controlling various devices.

55. I used this board to program the Free Scale Microcontrollers in my microcontroller-based designs.

56. I designed this smart switch that connects to a Microcontroller and recognize claps to do various actions such as appliances and equipment control.

57. This is a dev tool that I used to program my 50 MIPS microcontrollers.
