Simple null modem without handshaking
“only the data lines and signal ground are cross connected in the null modem communication cable. All other pins have no connection. An example of such a null modem cable without handshaking can be seen in the figure below.”
This is a Linear Dynamo LED Torch which uses a SuperCapacitor to store the energy. Easy to repair and maintain if necessary.
Forever Flashlight
It uses no batteries and requires only the single LED included. You can even leave the flashlight unused in your car’s glove box for years and you’ll always get that all-important light when you need it most. Forever Flashlight lll pays for itself quickly by saving you the cost of batteries and bulbs.

Jonathan Westhues site of Intriguing Projects include A Test Instrument for HF/LF RFID and a compiler that starts with a ladder diagram and generates native PIC16 or AVR code.
Toy SMPS or an Overkill White LED Driver
I sense the load current and control the duty cycle. The PWM pin on the AVR drives the gate of the FET through a couple of BJTs. Note the absence of any input capacitance; Vin looks terrible but it works. The micro power supply section is isolated with an RC.
delabs Notes
This is a nice way to start, learn uC and Power electronics in one go. It does not matter if it an expensive solution for LED Lighting. It certainly is an excellent Educational Project.
It may also be useful to use Intelligent Systems (uC and Firmware) to monitor and manage LED Arrays and control their brightness and color. Large Arrays can be Interfaced to PC by XBee for Home/Office or Factory Lighting Automation and Energy Consumption Optimization.
uC Real World Interface
uC I/O is Keyboard and LCD when you Build a calculator or a Text/Morse Communicator. When you control a motor it is Drive/Speed and Direction for Motor and Tacho or Opto Counters for Feedback. In both cases you have Input and Output which is Logic or Analog which has to reach the CPU.
Pinguino is an Arduino-compatible open source hardware electronics prototyping platform. It supports different 8- and 32-bit microcontrollers, all with built-in USB module
Pinguino – Arduino-compatible for PIC
Pinguino Software is an Integrated Development Environement (IDE) which gives everyone the ability to write, compile and upload programs on a Pinguino board.
Pingubot is a small robot based on Pinguino 8 bits. Furri and Bastian designed this board to teach how to drive a robot with Pinguino.
Before Hams invented DIY Electronics and even before Electric Current gained any respectable position in the Manufacturing Community. The thing that was making many heads nod in unison, was Steam Engines.
Coal, Steel and then Steam Engines made the word Industrial Manufacturing very Meaningful.

Electronics Australia and EA Today
Electronics Australia was one of the longest running and most respected electronics publications in the world.
Electronics Australia & Silicon Chip Magazines
Dave now supports the only remaining Australian electronics magazine – Silicon Chip.
This was made by me when i was a kid, it was even published in a magazine, i think it will work, it was used on a very old huge ornamental valve philips stereo system in the remote speakers.
Recently i captured this circuit in eagle to publish online, it seems to have a small design error. It worked well for many years. The step-down transformer is used as a step-up here. The secondary winding was around 50mA so the resistance was protecting the 2N2222. (SL100 was used in the original one). C1 and R3 may need tweaking to get the desired adjustment range in R2.
The voltage across the speaker is fed to C1-Gnd, which blocks DC component. R1, R2, R3 form a threshold bias for T1. 2N2222 chops the 12V DC in tune with the music. The chopped DC current flowing in the 12V winding of TR1 is stepped up into AC pulses over 100V, this lights the Neon in flashes synchronizing in real-time with the beats. Known Issues – It does not perform well at low Bass like 20Hz.

Wouter van Ooijen runs VOTI is an engineer who has worked on many software and systems projects. He has a Webshop with PIC Parts and Kits. His PIC FAQ and “blink a LED using one of these flash PICmicro controller” is great for beginners.

A circuit that generates a voltage that rises slowly from 0 to 10 Volt and (when a switch is flipped) slowly back to 0. The request did not pose much restriction on the wave form, but a rise / fall time of 30 minutes should be possible.
I got a mail question, which i logged here Long Duration Linear Sweep or Ramp Generator. The above project could be an neat answer.

Arduino Nano is like the Arduino Mini, but smaller. Allows rapid prototyping on a breadboard.
Comes with chip version 3.0 ATMega328. ICSP connector for external programmer. USB mini-B connector for programming and serial communication. Integrated voltage regulator. Pins-spaced 0.1 “DIP for insertion directly on a breadboard
“I was goofing around the other day thinking of ways that I could use NFC with RoboBrrd. I got a few NFC tags and was also getting a robot achievement badge (thanks Adafruit!), so there had to be some way to connect these things..” – What a Hat can do
This is an Interesting Life Form. The RoboBrrd reminds me of Ancient DictaBird from The Flintstones (1994) Movie.

I would prefer one that that may be useful on the Desktop like the DictaBird. That reminds me of another Bird called ‘SMS’ in Asterix and the Vikings. So an Interactive desktop communication helper in the form of a Extra-Smart bird. Like Daisy perhaps. Something Fuzzzy or with AI like …
Daisy’s primary purpose is to be able to converse with humans.
“What separates Daisy from Billy (and most other chatbots) is that Daisy has no pre-programmed (or hard coded) language of any kind. She starts with no knowledge of anything, but then is able to gain knowledge as she observes what humans say. From this, she is able to remember patterns of words, and the probability of these patterns occurring. Using this data, Daisy is able to actually generate her own..”
See on the right is another green bird, it could have been inspired by the DictaBird. He is Peedy the Green Talking Parrot, he also happens to be an MS Agent.
