AVR HV Rescue Shield Kit - mightyohm.com
Includes PCB with pre-assembled DC-DC converter, all components required to build the kit
The AVR HV Rescue Shield is a high voltage parallel mode fuse programmer for Atmel AVR microcontrollers. It currently supports the ATmega48/88/168/328P series and the ATtiny2313.
I found this bright flash of information when i was looking for supercap vendors
On this page of Microscopic Society of Southern California (MSSC), i was enlightened about this Battery Less wonder. This is a boon for rural areas and an emergency tool which depend only on your will and your tendons.

PICAXE - Powerful uC Programming
The 'PICAXE' system is an extremely powerful, yet low cost, microcontroller programming system designed to simplify educational and hobbyist use of microcontrollers.
The buggy is a mobile robot having microswitch sensors- LED eyes- piezo sounder and worm drive gearboxes using high quality solar motors.The microcontroller and battery pack is built onto the buggy- so that it is totally self contained.
N5ESE - Gizmos for QRP Ham Radio
At "GIZMO's" page, where you'll find over a dozen weekend projects that are tailor-made for the QRP homebrewer. (#17, below)
N5ESE's Version of the W8DIZ Frequency Reference
"Dieter Gentzow, W8DIZ, of Kitsandparts.com provides an inexpensive ($17) kit that generates a trimmable, crystal-based signal of reasonably good stability for use as a hobbyist frequency standard"
Pic Projects from Mondo Technology
These are many projects you can try out with Microchip PIC. Code and schematics are there. You can build it then start tweaking or altering the code and later modify circuit. This is another way of learning. You must be sound in building analog and logic circuits first.
This is the order of learning ..

NE555 Applications and Specifications
Probably the very first Datasheet and Application Note of 555 the e-lego.
Signetics made the 555, This is one IC that is like a E-LEGO, this along with Op-Amps and other components can make many interesting projects. On some pins like Control Voltage it responds to analog signals and on Reset and Output the signals are Digital like. The 7555 a CMOS version consumes lower power and oscillates at higher frequencies. This evergreen or perennial chip is the favorite among students and hobbyists who want to learn electronics. Here is an original datasheet from Signetics i found online, it has very nice illustrations which will act as an appetizer for learning this science.
I want students to look into these specs pages as it will make your study more invigorating.

Model Railroad Electronics - Rob Paisley
"Electronic circuits that are mostly for model railroads. Shown are designs that were developed to solve certain problems or achieve a desired control function. There are throttle, train detection, animation, control and general purpose circuits on this page."
There are also some ideas for LEGO Brick
