Hi! Let it first be known that I have absolutely no training or real knowledge about circuitry or electronics. I'm hoping to get better at it, but I've never gotten any formal training and all that I've learned is from the internet. I'm pretty sure my soldering technique is wrong somehow.
Now that that's over with, I need help on a little project I'm working on. For the past two weeks I've been trying to construct the micro FM transmitter from this website: http://anarchy.translocal.jp/radio/micro/howtosimplestTX.html
The website is a little hard to navigate, but it's all there. This transmitter was said to be a good beginner project, but I've run into some problems. Whenever I plug the 9v battery in, it starts to overheat. I'm not sure whether it's actually broadcasting anything since I've never left the battery in long enough to find the frequency it's transmitting at. I've built it twice and I've had the same problem both times.
I substituted the default transistor for the NTE123AP as the website suggests and shifted some things around to account for the different lead positions. The trimmer capacitor I use ranges from 5-25 pf. Aside from that, I've followed the picture quite faithfully. I've double checked with a multimeter that no solder is touching the ground where it shouldn't. One possible problem is that I've damaged the transistor while soldering. Would that cause the battery to overheat? I may have held the iron on the leads too long or held it too close to the plastic body.
Any help at all would be greatly appreciated!
