This is an LED flasher kit based on NE555 and 74HC595. The LEDs on this kit scroll and give a water flowing effect. The bistable circuit formed by NE555 and 74HC595 generates an oscillating pulse and adjusting the value of RP changes the oscillating frequency so that the flowing speed of the LEDs can be…
I recently built a DIY electronic game kit. It has 4 games: tetris, snake, plane and racing. This is the fanciest electronics DIY kit in our catalog. A do-it-yourself arcade video game! The 8 x 16 dot matrix display is of course not up-to-date, in the age of 4k UHD. But it is a lot…
We have been using different online Gerber viewers for checking our Gerber files before sending the PCB designs for manufacturing. We have now started using EasyEDA’s Gerber viewer because it helps us to visualize the PCB that would appear after it is manufactured. The application is pretty straightforward and we can check different files to see the changes on…
