Upon recently stocking the BA1404 FM Transmitter IC chip, I began to build a transmitter using one and I realized that 38KHz oscillator crystals are needed, so I ordered several of them and we now stock them for your convenience. You can get yours from our store at http://mklec.com/38khz-crystal-oscillator.
The ROHM BA1404 DIP-18 IC is a truly unique chip. With this IC and a few external components, you can build your own stable FM stereo transmitter. That means you can make your own wireless FM microphones, pirate radio station, and car stereo transmitter so you can play your MP3/iPod/iPhone music through your car stereo with clarity. The great thing is this chip operates on a single 1.5 AA battery and features low power consumption. If you don’t have one yet, you can get yours in our store at http://mklec.com/ba1404-fm-stereo-transmitter-ic
There’s a few crucial external components you will need to build this circuit. I’m going to be using the circuit found at http://www.electroschematics.com/54/ba1404-fm-stereo-transmitter/. I’ll make a complete parts list soon, but the main things outside the standard components is the 38KHz oscillator crystal and the 3.5 turns RF coil.
We’d love to hear from you on your experiences with this IC and even show off your build. Please feel free to post a comment below and/or visit our Google+ Community and share there.
I’m pleased to announce a new product we’re carrying … 29mm (1-1/8in) diameter small/mini speakers. These small project speakers are excellent for audio output applications where a small, lightweight speaker is the most ideal choice.
These are rated at 8ohms 0.25watts.
We’ve added another assortment pack to help starters/hobbyists/enthusiasts/etc. stock up on a variety of products. We’ve assembled a diode assortment value pack that includes 1N4148, 1N4007, 1N5819, 1N5399, 1N5408, 1N5822, FR107, and FR207 diodes.
I wanted to let you know about a product I’m excited to offer and one I personally have needed when I was getting started with electronics.
I’ve assembled an assortment/variety pack of multilayer monolithic ceramic capacitors containing 29 values, 5 of each value. This pack will prove very valuable as you build various circuits and discover how it has the values you need, meaning less time ordering/waiting on parts and more time building your projects!
