Frequency division by any whole number in software is trivially easy. Even fractions aren't too difficult. There is minimal advantage in choosing a specific...
You all talk about free-running crystal osc as a clock source, no matter how expensive the osc is and how well it is adjusted, it will drift over time and the...
... I have noticed that mains clock frequency sourced timing causes my clock to run upto 5 seconds out across the period of 1 day, re- synchronising later for...
Hey Nixians, Ever since the conception of the JK flip-flop, it has been a complete mystery what "JK" really stands for. The prevailing theory suggests that J &...

Recently, we got a great collection of National Semiconductor MM53XX series clock chip data sheets, along with info on the 7-segment Panaplex deriver, the...
I just added another couple boards with one more SP-353 and ten or so DM8880/DD-700 panaplex drivers to the auction below. They also contain three extra...

... This is indeed true, but a "hybrid" timebase is the ideal solution. Use a crystal-based time for the 1 second ticks, but recalibrate it once each 24-hour...
Hi, perhaps someone can help. The clock is running too slow. The clock uses the following ICs inside: F 38170 PC 7646 V Does anyone have a datasheet for them...

Hi Tom Frank, Yes the water cannon and the camera are included in the plan..I forgot to mention them ;-) I have pumps and som micro color cams. Your idea with...

There was a part that did what you all are talking about. I think the National part number was MM5369. It would take a color burst crystal and divide it down...
... Dave, The color burst is related to 60 Hz, but in a completely unusable way. The old black and white TVs scanned at 60.00 Hz vertical rate. Then color came...
