Counter Objects with Calculator and Laser Beam

Counter Objects with Calculator and Laser Beam - This project of an object counter uses a common calculator to do the counting and a laser beam pointed at a sensor to detect the objects to be counted.

Genius. its impressive how you did the counting without making programming any microcontroller and a display.

[@atulsoti1827]

Nice work, I did exactly the same thing in 2011 to make a tachometer.

[@mohammadebtaprakarsa7679]

very smart tweak of calculator :D
thank you so much for sharing the idea

[@crisium]

Thanks for watching

[@plexus07]

yes but how can you handle this if the calculator goes like off or somehow ? how do you get your the var++ ?

[@densek510]

nice, and thanks! ... but is there an app for such counting ? =)

[@yfaheem]

nice piece of engineering, a DIY counting system!

[@crisium]

Thanks for watching

[@guitarguy9402]

This would be very good to put on a basketball rim to count your shots

[@27-nguyenthaiduong41]

thanks you. I want to make this become my project. Can u agree?

[@hongsangang1224]

great video. Which laser receiver did you use ? pls reply, much appreciative.

[@techtinkerin]

It was a large transistor with the top cut off but there's probably something more suitable tbh

[@ritesh7285]

Light dependent resistor may be use or not?

[@manavarora3410]

Can we use any other transistor??

[@সাহিদুল]

Does any other type transistor work Without mj 11032?

[@sethawuku1729]

Can I use any other transistor

[@gouravsales7039]

1amp ka tranzistor laga sakte hai kya?

[@iamcurios]

Which transistor used?? Specification plz

[@jorgecostaphotography]

Nice video
Can we remove the red light of laser?!!

[@tanismansuri6889]

LDR can be used instead of sensor?

[@nitheshnithu9027]

Which kind of transistor that one plse let us know

[@crisium]

transister MJ 11032

[@snehamishra6694]

How did you get the transistor without a metal cap-like structure on it?...or if you had that how did you remove it?(I have the same model as yours i.e MJ11032). Please help.asap.

[@techtinkerin]

You carefully hacksaw the top off

[@VoiceofRuralRechapally]

what is use Transistor capacity number is not clear 2N62..? please tell me i am doing this project but not success

[@crisium]

transister MJ 11032

[@madhuradharme9131]

Genius

[@crisium]

Frozen Fire Thanks for watching

[@pratiknandurkar]

I can't able to find the transistor so any alternative for that?

[@mankind8776]

What u put on transistor

[@Walagaming26]

I can buy this?

[@omersurucu1453]

Amazing.

[@kelsevi6779]

does any kind of transistor work?

[@AbdulSattar-hc8yf]

Bro ap ny ya banaya hy

[@mohammedhusainhii2748]

Bhai yah transmitter ka number kya hai please bataiye na

[@vigneshc235]

Transistor name plzz tell

[@Pawandhiman_kapoor]

Sir PLEASE MAKE A RPM LASER METER PLEASE SIR

[@pp-jh4ig]

nice

[@satriorudi1979]

Good hack

[@crisium]

Thank you for watching

[@AbdulSattar-hc8yf]

Bhi tnansister ka number pata hy

[@xhtml5for1.0]

I will remove my stuff to nuclear

[@riyazshaikh8627]

Switch ka naam bata do

[@AbdulSattar-hc8yf]

Bhi transister ka number to bta do

[@crisium]

Abdul Sattar transister MJ 11032
Thank you for watching
