The recent aquisition of a pair of vintage Infinity RS-5b speakers prompted a search for an amplifier to drive them. According to the documentation that came with my speakers, an amplifier between 35W and 135W is recommended (not my 10W at 10% THD piece of garbage Sharp 3-in-1). Initially, I looked at commercial amplifiers (Yamaha,…
MLF QFN package with an integrated hard solder, a fine job .. how soldering with hot air gun in the video have been shown to help, of course, indispensable materials (flux, collets, etc..) Is used. Repair jobs you’re dealing Practice your hands get used made in China some digital pictures of machines MAXIM production advanced…
I used to implement a rampant LM3886 application BPA300 LM3886 notes will take a lot of time, but I couldn’t find the çizmeside circuit was just a search, I found the drawing but the pcb is double trouble. If you want to make, single-layer pcb design, symmetrical supply circuit, the input amplifier, 220v with soft…
TQFP32 in integrated circuits do not require soldering, especially for microcontroller projects, going to work is a handy TQFP32 DIP32 very good craftsmanship In handmade converter pcb solder after filling up with left, right bars soldered onto the sections. In order to facilitate the placement of the chip, the chip will form part of the…
Line following robot project, control of MC68HC908QB8 and PIC12F508 microcontrollers. Motor drive circuit used the L298. The system is complicated and cumbersome, but there’s a different robot projects useful sections PIC12F508-American SFH506-36 IR receiver solid (Infra Red Proximity Detector uses Sharp 38 or 40 kHz IRM) IRE5 sensor solid power supply regulated etc. is a…
12v dc voltage 240v dc converts to 2 different circuit. someone ir2153 with the other is crafted with 100w power output drive circuits can give tl494 floor transformer obsolete high voltage, tesla circuits made with voltage diode capacitor, we see the connection there usage restricted circuits the multiplexer also aren’t very healthy fee too but…
The Servo Digitizer is developed to channel control input from a model airplane radio remote control, the Futaba Skysport 4, to a flight simulator program running in a PC. It translates a pulse-width modulated signal output from the remote control into ASCII data and sends them to the PC via an RS-232 serial port. A…
Implement a simple user interface design using the Motorola Nitron microcontroller as the interface controller. Design the user interface with cost, reliability, adaptability and manufacturability in mind. The user interface design must be unique and provide a new novel concept in user interface design. Utilize the capabilities of the new Motorola E-field sensor. 68HC908QY4 An…
The Motorola 68HC908QY4 is used to produce an NTSC video signal which can be used in several applications. One is an NTSC Test Pattern Generator which produces simple test patterns in order to evaluate a TV’s geometric distortion, high voltage regulation, and interlace quality. Another is a VCR Pacifier to allow a VCR to record…
Ever wonder what the birds, deer, or bear were doing in your back “40” when you weren’t around? Just set up the Remote Observation Station, and you can watch the wildlife on your TV in the comfort of your living room! The station includes a camera and transmitter that sends a picture to your TV,…
