Instead, you will have to solder the yellow wire to the arm next to the screw hole, making sure the solder is low profile not to interfere with fitting the antenna through the slot. January 17, at 3: As an experienced kit builder, I wasted no time in getting started. I wonder if adding some holes in the back of the case would help.
To adjust the FM alignment, you need to use a flat blade screwdriver and adjust the right brass screw on the rear of the variable capacitor datasheeet. I must have used the wrong screw for the antenna as it became loose and I ended up replacing it with a self tap of slightly larger size. Use a fine-tipped iron and keep the tip clean. The IC type is YD I tracked down a datasheet and put it on my site. The only English you will find is in the listing description, which isn’t for FM reception, with the only datasheet I could find being in Chinese.

In reading the datasheet I had missed the part about them needing to be at 0 for the circuit to count normally. I am also concerned that my chip may be damaged from static discharge, however I think that is unlikely and my problem is a wiring problem. I was unsure what to do with the carry in and carry out pins so I left them unconnected cx4029 may be part of my problem. Each time power is applied to the circuit the LEDs seem to turn on in a different order. When I turn the power on the LEDs all come in a random order and stay on after the counting cycle has finished.
I redid the entire circuit from scratch, and eatasheet am still facing the same problems, so i don’t think it is a simple error that I made. When I tried to hookup the circuit according to the datasheet my circuit didn’t work as demonstrated in this video. My current problem is that I do not understand what I would need to do with the carry in and carry out pins of the to make the counter work as stated above. There seems to be very little information on how to use this ic. CD datasheet & applicatoin notes – Datasheet Archive I have studied the datasheet, and I still can’t figure out dataeheet to wire this up on a breadboard. I am trying to build a circuit that counts up to 15 or in binary using a ic and 4 LEDs as demonstrated in this video. The CDBC is a presettable up/down counter which counts in either binary or decade mode depending on the voltage level applied at binary/decade input.īy using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
