Thanks for the fast replying I really appreciate it ...I already did what you suggested about trying different values ,because I thought from the first sight 10kR might be too much , then when I made it , the LED emitting was dim . so after some time I figured the optimum value for that resistor was 1k . more than 1k will cause dimming of the LED, lower than 470R will cause LED flickering or Fail of LED Emitting with some transistors , dont know why acully anyway the project was handy and fun to make, so here is my last version of it with SMD componentsand thanks again for the link , helped alot.
Thanks for checking out my Instructable and welcome to the electronics hobby.I would love to say that I painstakingly calculated each resistor value for the optimum performance but honestly I made this project when I was just getting started and most likely copied the resistor values from another of my projects or a transistor schematic I had found online and didn't understand myself what they were doing.Looking at my terrible schematics (I have gotten better) I see that I used a 470ohm resistor as the current limiter for the LED. To avoid damaging the LED we need to limit the maximum current. The same is true for the base of the transistor. The 10K resistor limits the maximum current that will be allowed to flow through the transistor. If you have extra transistors and LEDs I suggest you try different values to see what happens, the worst that can happen is you burn up a few cents worth of transistors and LEDs and the best is that you learn what values of resistors are required. Also if you haven't already, check out how a transistor works from the best teacher on YouTube: Dave Jones. https://www.youtube.com/watch?v=qUeK7pHe0rI&index=6&list=PLvOlSehNtuHtWlH0UOZNtOn-FlFCn1GYw Don't worry about if you don't understand all of it, it is not necessary but still interesting and a good look into transistors. Check out his other videos, I have learned so much from watching random videos of his.Have fun!
Thanks , I've been looking for this circuit for long time , I just started the Hobby so I hope u don't mind, Can you explain to me why we used this values of the resistors at those specific locations Thanks Again

ola galera eu nao concigo abrir um servidor online ja tentei de tudo algum me pode ajudar.....???? se alguem tiver desponivel agradecia ......eu tenho o windws 10 e esta dificil metr o servidor online alguem que me possa ajudar gostava de poder fazer o meu proprio servidor online agradeço desde ja .... fico ha espera de uma resposta. obrigado
someone told me to configure Nat ! so me need to build a route or MAP from the IP address of your router, to the IP address of your SERVER (IPCONFIG). who can do this for me or tell me how to do it step by step ! www.facebook.com/inidri
This is very interesting. I broke the little handle gear last night and took mine apart. Thankfully I did not break the bearing thingies! I would have had to call my brother. I emailed Sizzix and hope they send me the gear soon. Ugh, two layers of denim on the tattered florals die. Is this the only die that breaks a Big Shot? LOL!!!
