dsPIC30F2012 breadboard

Bernard introduces us to the dsPIC microcontroller. He shows us his Arduino like project board for a dsPIC and gives advice on software development tools. This article was submitted by Bernard Klinc as part of the “Hobby parts for articles” program. Bernard received a graphic LCD module for this great article. You may remember Bernard

FTS 8 subtone encoder

FTS-8 subtone encoder

Many Yaesu transceivers from the 1990s and thereabouts could use an optional FTS-8 module, that provided subtone generation for transmission, and subtone decoding for CTCSS reception. One of the radios that used this module was the FT-736 multiband, multimode full-duplex VHF-UHF rig. I bought one of these radios in 1992, to use it on the

Hand Sign Lock

Introduction Security using technology is a growing and expanding field to protect against the user’s identity or property. As more advanced tools are developed, security has begun to expand to utilize a person’s physiology as a key instead of a password; for example, newer models of IPhones by Apple have fingerprint sensors as an option

Voice controlled wheelchair

Voice controlled wheelchair

The Project aims at controlling a wheelchair for handicaps by means of human voice. The speech recognition system is a useful way of implementation and is easy to use programmable speech recognition circuit. Programmable, in the sense that user can train the words (or vocal utterances) he needs the circuit to recognize. This board allows

Barcode Scanner

Barcode Scanner

Introduction In our final project, we used CMOS camera to identify interval binary 0 and 1 sequence represented by black and white bars. Then, we used WIFI module to transmit the sequence to personal computer and displayed it on a web page. In our projects, we chose OV7670 CMOS camera and ESP8266 WIFI module for
