PICAXE Goes Wireless , Pt 2 -  Networking.  logging data, plus light & temperature sensors__ SiliconChip

PICAXE Humidity Measuring using the HopeRF HH10D -  Recent SILICON CHIP articles on HopeRF 433MHz data transceivers have drawn our attention to other monitoring modules made by this Chinese firm.  Amongst their offerings is a well-priced and calibrated humidity sensor, the HH10D.  This has shown itself capable of extremely simple interfacing to even the humblest PICAXE, although factory calibration values first need reading via an I2C-level PICAXE such as the 18X.__ SiliconChip

PICAXE Infrared Remote Control -  Here's how to add infrared remote control to all your PICAXE-08M projects  (including Rudolph) __ SiliconChip

PICAXE Micorcontroller Controls Motor Speed-Direction -  Here we are going beyond PICAXE Controls TA8050P H-Bridge Motor with PORT Programming to not only stopping and changing direction of motor rotation, but to also control rotation in either direction.  I'll cover only the speed control part here. __ Designed by Lewis Loflin

PICAXE Microcontrollers -  Find out about PICAXE microcontrollers and their use in renewable energy projects.   __ Designed by REUK-Renewable Energy UK website

PICAXE Net Server, Pt.3 -  Over the last couple of months, we described how to built a demo board for the PICAXE Net Server  (PNS) and then configured a home network to make it accessible over the Internet.  This month, we look at building the first of two Internet-enabled demonstration projects.__ SiliconChip

PICAXE Net Server-Pt.1 -  Control your next electronics project from virtually anywhere on the planet using the Internet and a tiny web server - the PICAXE Net Server!__ SiliconChip

PICAXE Net Server-Pt.2 -  Accessing the PICAXE Net Server via the internet__ SiliconChip

PICAXE Operates H-Bridge Motor Controller -  Here we are using a PICAXE-18M2 microcontroller to operate a Toshiba TA8050P H-bridge.  While built on a PIC ship related to PIC16F628A it has a built in basic interpreter.  These functions while far easier to use than assembly still allow easy low level programming.  Like Arduino direct access IO ports, one has the same direct port access for speed and ease of connecting hardware. __ Designed by Lewis Loflin

PICAXE Project Development SystE - M -  With the abundance of microprocessor/microcontroller variations available these days it is no small wonder that many of the designs produced by electronic enthusiasts use one type or another of these components.  And most commercial equipment these days has a micro controlling it.  But how do you get from an idea to a working design?__ SiliconChip

PICAXE the Red-Nosed Reindeer -  It's based on the new PICAXE-08M chip, flashes its nose and eyes and plays popular Christmas tunes and mobile phone ring tones!__ SiliconChip

PICAXE VSM: the PICAXE Circuit Simulator! -  Ever wondered whether your latest scathingly brilliant PICAXE project idea would actually work? Well, now you can find out before you build it, with the new PICAXE circuit simulator software! Mr PICAXE, Clive Seager, talks us through the latest PICAXE software offering from Revolution Education.__ SiliconChip

PICAXE-18X 4-Channel Datalogger -  It features four input channels that can be sampled and stored  (or logged) at user-defined intervals.  An onboard EEPROM stores the data.__ SiliconChip

Picaxe-18X 4-channel datalogger -  Pt.3: adding a humidity sensor, more memory & a liquid crystal display__ SiliconChip

PICAXE-18X 4-channel datalogger Pt.2: -  Adding a real-time clock__ SiliconChip

Picaxe-Based 433MHz Wireless Thermometer -  You've no doubt heard of Murphy's, Ohm's and Moore's Laws but how about Swan's Law - "You can never have too many thermometers"?__ SiliconChip

PIC-based "TDOA" RDF (radio direction finder) antennunit -  Microcontroller based electronic circuit__ KA7OEI

PIC-based Flexitimer Mk.4 -  Here's a new and enhanced version of a very popular project: an easily-programmed low-cost electronic timer module.  It's compact, easy to build and offers a choice of either a single on period or continuous on/off cycling with independently programmable periods.__ SiliconChip

PIC-based Motor Controller -  On these pages, I will introduce a control circuit for stepper motor.  The software of this project is adapted to Embedded Systems  (Lab13) for 2002 of Cleveland State University.  PIC16F84A __ Designed by Seiichi Inoue

PIC-Based Musical Tuning Aid -  This compact device will help you tune almost any musical instrument - acoustic or electronic.  It can produce any note on the tempered musical scale    (standard pitch) in any of the eight most commonly used octaves, with an accuracy of better than ?0.08% or 1.3 musical cents.  The selected note is compared with that from the instrument either by ear or visually by using an eight-LED stroboscopic beat indicator.__ SiliconChip

PIC-Based Water Tank Level Meter Pt.2 -  Last month, we published the circuit of the Water Tank Level Meter and described how it worked.  This month, we show you how to build both the basic and telemetry versions and detail the installation.__ SiliconChip

PIC-Controlled Swimming Pool Alarm -  Reduce the possibility of a drowning in your swimming pool.  If someone falls in, an excruciatingly loud siren sounds.__ SiliconChip

PIC-DAS, a PIC based Data Acquisition SystE - M -  The PIC DAS was designed to fill a very real need which I always have in the Lab, which is: "How do I quickly read some data or control some hardware when the whole system isn't available?" I solved this with the PIC DAS a PIC based data acquisition system.  The PIC DAS contains a PIC Microcontroller __ Designed by Steve Hageman

PicoDetector : a PIC-based Simple Circuit & cheap metal Detector -  The idea of this circuit is to hack PIC oscillator circuit, by replacing the crystal by a coil : the frequency of the oscillator then depends on presence of metal near the coil, just like in a classic metal detector.   __ Designed by Bruno Gavand

PicoWeb V5.1 (AT90S8515) tiny web server -  Schematic Only __ Designed by Lightener Eng'r

PICProbe: a versatile Logic Probe -  A versatile PIC-based logic probe that fits inside a Biro case!__ SiliconChip

PICs in Space -  The circuit diagram is shown to the right.  You can get a larger version or a PostScript version if you prefer.  The design is based around a Microchip PIC16F628A microcontroller.  At the time of writing, this device is available for less than one pound from  (among others) Crownhill Associates.  All the work, including colour video and synchronisation signal generation, is done in the microcontroller, and so there are no other active components.  Purists who contend that the LED is an active component may replace it with a light bulb. __ Designed by mail at quinapalus dot com

PIC-Tock video clock -  PIC-Tock is a video clock using a PIC16C61.  In the tradition of Marv Newland's "Bambi Meets Godzilla", there is far too much ROM space spent on credits, which are smooth-scrolled horizontally on the bottom of the screen.   __ Designed by Eric Smith

Picxie 2 8x8 Animated LED Signboard -  The firmware supplied incurrent sourcecode archive is VERY BASIC.  I do intend to draw more patterns.  However, a vast workload coupled with possible emigration has putfinished firmware on hold.  Please do go ahead and build this circuit thoughsupplied firmware is fully functional.  You can have hours of fun designing your own patterns and effects!UsesPIC16F84 __ Designed by Lewin A.R.W. Edwards

PID Temperature Controller -  What's a PID controller? PID stands for "proportional integral differential" and relates to a process which seeks to continuously correct the error between a measured variable and a desired setting by calculating an appropriate correction process.  In practice, it can largely avoid the large overshoots and undershoots that occur in simple temerature control systems.__ SiliconChip
