Astable 555 timer - 8-bit computer clock - part 1

Hi Ben. Are you using a logarithmic potentiometer?

Hi Ben, Thanks so much for these 8bit computer videos, it made remember me when I worked with my OSI C1P in 1979/80, you can google it OSI chalenger C1P superboard, I had just the board, this in Brazil, probably one of the first personal computers in Brazil. I did build the clock as on part1, the led is blinking but it blinks very fast and if I adjust the potentiometer just a bit, it stops. Are you sure you used a 1MOhms potentiometer? Is it not a 100KOhms? Thanks very much for your help.

Also RE: Power Supply - I don't know if you watch EEVblog but he has a video on "Fake Apple USB Charger Teardown"- it make you wonder if you really want to use one of those USB chargers. Here is the Video >> <a href="https://youtu.be/wi-b9k-0KfE" rel="nofollow noopener" target="_blank">https://youtu.be/wi-b9k-0KfE</a>. I would like to make a suggestion to an alternative power supply: SparkFun's ( I don't work for them, but I bought this long time ago, and it works with out the worry of being electrocuted. ) <a href="https://www.sparkfun.com/products/13032" rel="nofollow noopener" target="_blank">https://www.sparkfun.com/products/13032</a> . It uses a Wall Adapter Power Supply to run it >> <a href="https://www.sparkfun.com/products/298" rel="nofollow noopener" target="_blank">https://www.sparkfun.com/products/298</a> if you want more power >>> <a href="https://www.sparkfun.com/products/114" rel="nofollow noopener" target="_blank">https://www.sparkfun.com/products/114</a>

Ben, sorry I cant find where you talk about the power supply but I wanted to point out that you made a Buck Converter with using the long leads. All that wire between the Apple power supply and your bread board is acting like a really neat inductor boosting your power.
