Unprecedented Innovations from a young group of Scientists who may change the way we interface with the Electronic Environment around us.

EMS Laboratories – Hobby Electronics

Meggy Jr RGB is designed to be programmed through the popular Arduino software environment, when you hook it up to your computer with an FTDI USB-TTL cable

Meggy Jr RGB

Meggy Jr RGB is a new kit that we designed as a platform to develop handheld pixel games. It’s based around a fully addressable 8×8 RGB LED matrix display, and features six big fat buttons for comfy game play.

A unique feature of Meggy Jr RGB is that it is designed to be mounted inside a “handle set” — a wooden or plastic case that’s safer and more pleasant to hold than a bare circuit board.

The following was submitted on July 11th, 2007. Message: I want to combine Ne555 with 74154 IC.The indication of the outputs must be shown with LED’s but up to so far it need 15 outputs ,is it possible the way i did? if not i will need your assistance

Mail from CY

LED running lights are used to decorate Christmas Trees, Festival Surroundings and even  Buildings. A Clock and a counter are basically required. Many LEDs can be used in parallel with driver transistors. Upto 15 count is is good enough. Many colors can be used and with a PWM or VCO you can make it Audio or Music effects lights like strobe lights.

Multi-Colored LEDs and drivers and even PIC microelectronics with Visual Effects in the form of ROM tables can make Alphabets and Numbers appear in LED arrays. Some have made Mini Ocillosocpes and Toy Spectrum Analyzers too in LED DOT Matrix Arrays.
LED Sequencer Circuit

The above circuit is another variation of a basic LED sequencer circuit. Note again the use of the 555 as a clock. The 555 is likely one of the most versatile chips ever invented. The output of the 555 is coupled to a 4017 Decade Counter Divider another very widely used chip

With the best wishes for you. I found your address and browsed your website. I have a question and hope to take your help and answer.

I need to good metal detector’s circuit and I find several in the web, any of them worked ? what is a problem in them and where can I find one that works with best depth? Could you design or point the mistake in some circuits? Thank you for your answer beforehand.

Thank you for your answer and sites. But some of them that are professional namely “twin loop” built but it has problem and didn’t work.

I think it may be a indicated, there is a problem with them. How can I make it correctly? could you proper design such circuits?

I am not professional and of you do, I will pay for your works.

Reply from AS

If you clearly specify what you want with a drawing, And indicate what you may be able to pay and your contact details too…….

Then, I will publish your request in my site. People visiting my pages may contact you. You can Try it out, I may not be able to help now.

Christmas Tree - CircuitStew

Develop a Skill this Christmas, Build these small LED Trees and give it to people who need a little bit of cheering up.

Christmas Tree – CircuitStew “This was the first and last complete prototype that I made on proto board. This style of prototyping produces circuits that are very difficult to understand, debug, and modify. Because of all the extra work involved they also take forever to assemble. Suddenly I became very interested in designing and fabricating custom pcbs….”

The name CircuitStew refers both to the jumble of electronics presented here and to circuit boards suspended in neon green copper etching solution. – Derek Wolfe
