Basic PIC18F4550 USB Communication Interface - When the device is
connected to the computer, a Virtual COM Port (VCP) will be created.
This is shown at the Device Manager Window under Ports(COM & LPT). In this
case, COM5 was created when the PIC18F4550 was attached to the USB Port. It
may be interesting to note that if you plug in your PIC in different USB
ports, the VCP created will be different. ….(electronic schematic added

Basic routine simplifies factoring - 09/12/97 EDN-Design
Ideas.... Logarithms greatly simplify mamatical operations. Factoring,
however, presents a problem Pocket calculators are clumsy when it
comes to that operation. The program factor.bas (Listing 1]is a....[Design

Basic Stamp Based Altimeter - A method of determining altitude is by
use of barometric pressure; however, it is not done without difficulty. The
relationship of pressure vs. altitude is not a linear one, it is actually a fairly
complex one, which army came up with in 1930's. This is
equation for calculating(added 4/05) |

Basic Stamp Computer Eases Prototyping hassles - 04/09/98 EDN-Design
Ideas....Many of today's complex ICs use a common three-wire serial interface to
provide programming access. These ICs typically end up in circuits that include a µC
or a CPU, and the controller or CPU then has the burden of programming the serially
controlled....several circuits included, scroll the find this one....[Design Idea by

Basic Stamp I & PC Relay Controller - This project shows you how to build a
relay controller using the Basic Stamp I interfaced to the PC serial port. The
Visual Basic 5 software developed for the interface lets you interact with the Basic
Stamp to turn ON/OFF up to (2) relays attached to the Basic Stamp I/O pins. As
shown below in the screen capture of PC-Relay, it's easy to select the desired com
port using the drop-down menu....(electronic circuit added 4/05) |

Beam Robot - Most of the BEAM robots I've seen on the net are using hardware
analog electronics. It seemed that a PIC would work very well for this kind of
project. Very little extra circuitry is needed to do both forword and backword
walking sequences along with a few other tricks. The PIC16F818 has a lot of
features that work well in this situation....….(electronic schematic added 08/08)

Bench Supply - This unit delivers 0 to 20 volts at up to 4 amps in 0.1 volt
increments. The entire device runs on a PIC16F870 (about $3 in small
quantities). This is basically a switching power supply with the voltage
regulation done in software…. [Luhan Monat - Mesa Arizona] |

that I wouldn't have to keep buying batteries for the headlight. The headlight
is a 12 watt Malibu light from Home Depot complete with a very good diffraction lens.
The horn is a scavenged auto alarm from Walmart. I just use the horn with….

Boot loader for TMS320 uses bytewide EPROM - 04/25/96 EDN-Design Ideas The
price of high-speed DSP chips continues to drop. The devices pack a lot of horsepower
into small packages and are widely available. In contrast, high-speed (<-4-nsec]EPROMs
are not only expensive, but also scarce. To enhance the usefulness of their chips,
DSP-chip manufacturers include an onboard boot-loader ROM....[Design Idea by Robert

Bootstrapped Boost Converter operates at 1.8 Volt - 04/23/98 EDN-Design
Ideas....Many circuits, such as those that use batteries or solar cells, must operate
in the face of decreasing supply voltages. The circuit in Figure 1 maintains the
maximum load current as the supply voltage drops. The regulator boosts a 2.5 to 4.2V
input to 5V....File contains many circuits, scroll to this one....[Design Idea by Tom
