LED Light Bulbs in LED Lighting

LED Lighting is not another Florescent Lamp or CFL, it has a Luminous future. Some Manufacturers have hurried a bit and made some below average quality products. We can say many are on Beta Stage. Let us not spoil its reputation or market, due to these guys.
Keep improving, there is no other alternative. Edison lamps i like, but are power hungry. CFL's are fragile and fail often. LED is important, we need to make it happen. Every designer and manufacturer has to be reliability concious and be very serous about it. If we cannot do a good job, let us not do it at all.

Quick look at Some stuff i use – made



Its a Paper Mache Ball on Ferrite. The Base is a DIN Bezel. Many parts are Electromechanical and Electronic Metal Hardware. Plastic Caps and Reed Relays too.


Thanks Weller for making the Best Soldering Iron

Prototyping to prove a Design Concept

Before simulation in EDA tools. First stage of concept proof or design tweaks were made on BreadBoard, Stripboard or General Purpose PCB.

Even now it is used after simulation or directly. Many RF and Power electronics designs may have to be verified and modified on Pilot Production. Digital Designs and Software/Firmware checks don't need hardware prototypes, but need a proven framework to test it on.

Prototyping to prove a Design Concept

Hobby and Education learning must use breadboards alongside simulation, even though educational eda tools are used. Breadboard connects us with the reality, the way it is. Then you will even simulate better. Robotics and Developing Mechatronics Solutions may need prototyping and modifications many times over.

Soldering and Shiny joints are everything in electronics. One dry solder, a cut track, a solder bridge or splatter near the IC can make a card malfunction.

Thin copper tracks taking high currents, HV and LV circuit isolation, Ground loops, RF Antenna Effect, Ground Plane and Guard rings are just some things to know on Component to Component Connections, that make a huge difference.

In Design Notes of Soldermans Basic Electronics you will find my learning notes in electronics. How this learning happened ?

I had setup my Hobby Science/Electronics Lab when i was in School, In college i was helping others learn practical electronics. I worked in Product Design and Engineering Departments when i was Employed. During this time my Electronics Lab was a Free Training Center, sponsored by my own pay. Then i started my manufacturing firm.

Gabotronics – Oscilloscopes and Embedded Kits

Designs and manufactures embedded systems. Specialized in 8-32 bits microcontroller projects, instrumentation and data acquisition, PCB Layout, custom electronic designs and engineering consultation. Based in Palmetto, FL.

Gabotronics - Oscilloscopes and Embedded Kits

COMA+ The All in One Instrument, will enhance the original specifications, like using a TFT display and using a few external ICs to simplify the design, like the ICL7135 multimeter IC, and a DDS to generate the waveforms, probably the AD9833.

Is it a Calculator, Oscilloscope, Multimeter, Analyzer….; No it is The Coma+ .

Gabotronics - Oscilloscopes and Embedded Kits

Some Features

  • 2 Channel, 8bit 16MSPS Oscilloscope
  • FFT on acquired data
  • 8 Channel Logic Analyzer
  • Arbitrary Signal Generator
  • Frequency Generator
  • Multimeter:
  • Volt Meter, 1 M ohm Input impedance

Coma+ - An Instrument that propels an Engineer to a Superconscious State, It is under development. It was preceded by Coma an instrument capable of performing multiple tasks, data acquisition, signal generation and multimeter.

School Bus Conversion to Steampunk

He has many achivements to his credit; From converting a Thomas Saf-T-Liner, a flat-nosed diesel school bus into a family camper To a DIY Op-Amp Hot Tub Temperature Controller.

 DIY Op-Amp Hot Tub Temperature Controller

Look at Mr. Jake von Slatt, How he done things. This is what we learn from him …SteamPunk Workshop Guitar Amp

Jake's School Bus Conversion and Other Projects

Jump into the problem and solve it, See the way a Creative DIY Enthusiast solves an automation problem at home. The Job gets done this way, such seasoned people are rare. Now the idea is …

Think - Deliberate - Draw - Build - Test - Install

We all get stuck at the 'Deliberate' step, If its team work, a few should leave the desk and the conference rooms and start Prototyping and Simulating. This helps understanding a tough problem. Better still find a fast and simple solution.

Then there is that Sensational Site That Jake Built - The Steampunk Workshop. This is where it all Happens.
