FM Radio...

Wednesday, October 3rd, 2012 FM Radio Tuner Radio which still exist today on average in each area is FM, AM radio rarely still airs. even though it has a lot of HP which can also be used as a radio, but it does not hurt us exercise make your own radio, FM radio tuner that is Anti hiss. Actually radio proposed here in the market has also been a lot, because it follows a series published by the famous PCB maker is Ronika SC-907, and where she challenged ??? Well, the question may arise of your minds, is now used to prepare a series of Ronika komponenya appropriate, but eet PCBnya create yourself ........ I'll be practicing making PCB, OK! How to make PCB layout there are two, namely manually and using computer software, up to select which one? but if times have advanced so better to use a computer, it was counted as exercise also makes PCB layout software, can use Express PCB, EWB or another, now become more ilmukan ??? ya example make a PCB itself, although still less than perfect, but okay ........... continue by moving to the CCB / PCB plain how ?? there are two ways more trendy today, ie after drawing the layout printed using a printer LASERJET or Copied, the way is: a. Taped and then ironed, so that the existing image on the paper moved to CCB / PCB plain, but after a few times of practice there are obstacles such as: the first paper to be paper photo / glossy could also use the former is certainly the glossy calendar. The second moment is moved using if the iron is too hot, the copper can be bothered to peel .... wah donk. b. This method is often attempted and thank God a lot of success, ie after layout diprinter with Laserjet or Copied enough with better 60gr plain paper, then put the water that has been given SOFFEL (anti mosquito), after CCB / PCB plain cleared with the dregs, stay taped and swiped unidirectional using a ruler flat lined with plastic to paper rips, then remove the paper and thank God so. Well stay dissolve into the liquid PCBs ferichorit, remember a mixture of water and ferichorit must fit, so fast and secure means not make another chipped. followed by drilling and installation of components. in order to quickly see the layout of the component layout below. well hopefully this experiment is successful, though more stable not include a picture series of the Official PCB maker Ronika following SC 709 ..........
