.. by Elite Worm with an Arduino clone, laser, and sensor for about half that cost (Figure 1). You’ll also need a 3D printer for the housing, though you could probably get creative if one’s not available. Рисунок 1. Laser ...
.. short circuits but can push the power supply above its nominal load value. This scenario occurs with typical loads such as printer heads and small motors. When facing such a load profile, the power supply can easily trigger its protection ...
.. in most PC add-on cards. One more approach is to attach a simple 16-bit counter, such as the CD4040 and CD4520, to your printer port using the necessary buffering and control (Reference 1). In the last two cases, you can exploit a ...
Tachometer is a device that measures the rotational speed of any shaft or disc. The unit of the measurement is usually revolutions per minute or RPM. The traditional method of measuring RPM of a rotating shaft was based on velocity feedback concept ...
.. one of them on when switching the rest off, a slave switch is often used. Applications which spring to mind are a computer/printer/scanner etc or audio amplifier/record deck/tuner combinations or perhaps closest to every electronics ...
.. know what you are doing. The Makefile in lcd2usb/firmware/Makefile assumes, that you are using a simple STK200 compatible printer port adapter . Connect the assembled device (no display required yet) via USB to the PC. It will not be ...
.. to provide a cheap generic i2c interface to be attached to the usb. It is meant as a replacement for those simple and cheap printer port to i2c adapters. A USB solution has several advantages incl. the built-in power supply and a more ...
.. wire which was installed where needed. Notice from the photo that I use homemade wirewrap pin labels - I print them on the printer and push them down over the pins. Works quite well. I also print out top of board ID labels. This project ...
.. Clock. Since we tend to loose power on a semi frequent basis, this would have been a handy feature. I used regular laser printer paper for the lexan and then laminated it and stuck it to the front panel using double stick tape. The ...
.. the drill is operating. Another example: a desk lamp could be connected to the Control Socket and a PC, a Monitor and a Printer could be connected to the Switched Sockets and will be running after the lamp is switched on. Switching off ...
