Hi,
Mr C,
Could you help me sort out the cct? When I ground R5 nothing happens....How should I go about finding what is going wrong in the cct. Any help would be appreciated. TIA...RMHC.
Hi Mr C,
I would really appreciate any help you can give me getting the striking circuit to work. I have double checked the breadboard connections but still am getting no count o/p. Looking forward to hearing from you. RMHC.

I was going to write the code for you but hey this makes it easier on me too now.

So you probably want to check out post #60 where member "cruts" was nice enough to provide what looks like a working design. You can probably tweek the timing to suit your needs.
Mr Al,
I am still looking for help with my clock striking project. Unfortunately the circuit I received is not working and I want to proceed in the direction you put forward. The count is triggered by a pulse from a pair of contacts on the clock at every hour. The counter has to count up to 12 and the reset to 1-in other words it should not strike 13. I would appreciate any help you can give me regarding what I need to purchase and how to get it working. Many thanks RMHC.

Measure the voltages on all the counter pins and post them here.

So have you given up on the microcomputer idea? It would be much much smaller than a discrete solution. An 8 pin DIP IC, a handful of resistors , a couple of push buttons and one logic level MOSFET. I’ve written the code for you already.

I’m sitting at a bar, and thought of a different way to set the number of chime. I’ll provide a change if you want to try a micro.

@crutschow Just wondering? When the circuit is turned on, how does it know the current time? Doesn’t it need to know where to start chiming?

Maybe that is readable. I sure hope so.

Hi 'disfantasi'
I am interested in your idea for a microcomputer chimer, please give me more details regarding the IC chip needed for this and how it is programmed. You say you have written the code but how would I load it on the chip? I am having trouble getting the discrete circuit running also space is a concern on the clock. Please give me a part # for the IC, I have a L L N channel Mosfet already and scads of resistors etc. Looking forward to your next email. RMHC.

So, the chip you would need is an ATTiny85. If I remember, it’s about $3.00.

To load the code, you’ll need a development environment and a programmer.

I recommend the Arduino IDE. It is free! Copy the code and paste it into the IDE code window.

I recommend that you purchase a plug and play programmer. The programmer will plug into your computer/ laptop. The Arduino IDE will recognize it. All it takes to load the code is two or three clicks. I use the programmer from Sparkfun.

If you understand this much, I’ll provide more detail. While you wait for me, download and install the Arduino IDE. Check out some sample codes!

Im about to get on a ride at Disney. TTYL?
