cogitoErgo: Sorry Princejude, I used my laptop and I saw the price list, with 16f887, everything will cost 13000naira.
@princejude, I just saw something on BBC Click program now and I dont know if microscale could also organise such thing in Nigeria, its called Maker Faire! its a kind of an exhibition where all home techys and tech hobbysts will show their handwork and have a chance to interact.

cogitoErgo: @princejude and others, please I need a little help here! I have this project idea where several switches (reed switches, like 8 ) will be connected to a PIC, if any of the switches closes(one at a time), a message will be displayed on a 16x1 lcd. The message displayed depends on the switch closed.
Please, which PIC module do you think will be most suitable for this type of project?

princejude:

PIC module? ...do you mean PIC internal peripheral module or PIC microcontroller?

cogitoErgo:
sorry, PIC microcontroller

princejude:

any pic (from 14-pin I/O) can do that.

usisky: PEACE ALL.

@ Jude. i wanna know: what fascinating projects have u designed thus far as an electronics expert or enthusiast? PEACE!

usisky: ^^^peace bro'. Cool! Wish u success. Are u strictly into digital designs or do u do analog designs as well? I mean like power electronics stuffs? Maybe SMPS designs....either DC-AC, AC-DC Or AC-AC power conversion systems? Just curious, dats all! Thanks and good job

Vision

Microscale’'s long term vision is to be a world recognized leader in the creation of intellectual property i.e. patents and royalties for the global semi conductor hardware and software design industry currently estimated to be worth $260 billion

Mission

Our mission is to promote electronics as a viable industry in Nigeria and to be a one stop shop for products and services required to produce all electronics product.

Welcome to our Student and Hobbyist Webpage

There are so many electronic projects you can embark on that cost you less and brings you much pleasure and commercial benefits. A lot of electronic devices available in the market today started from a simple hobbyist project and have become house hold products generating revenue in millions.

To all our Electronics Hobbies enthusiasts and Students, Electronics designers who are determined to improve their knowledge of electronics, acquire practical skills through DIY design, build final year projects, Customized Electronic Devices, we provide the support, materials and training that you need.

Our objective is to improve the quality of engineering graduates, Electronic Designers in Nigeria by providing them with low-cost products and services. Our products and services make it affordable for an average student, beginner to be able to develop his engineering skills. You can Source your electronics products using our online store or contact us directly. We have supplied Million worth of components to buyers all over Nigeria using our 24hrs delivery service.

Furthermore, our on line tutorial provides useful material with lots of example projects that you can use to accelerate you learning time. Visit our online tutorial via http://microscale-embedded.com/blog/

Tips on getting started

1. Get a simple electronics text book that shows you how to identify, read and test electronics components

2. Buy some basic components like resistors, capacitors and transformer and design your power supply

3. Get more materials on project design via the website and carry out experimental projects

4. Contact us for technical advice where necessary or apply to us for more practical training from

5. Start today

Online Store

Our online store is designed to cater for students, hobbyist and research institutes who want to buy components in small quantities to produce their prototype.

Our range of components covers microcontrollers, LCD display, LED, sensors and transducers, modules for RF communications, GSM Modem, GPS modules,Finger print reader, RFID etc. Customers who want to do production should use our contract design and/or manufacturing service, where they can get a lot of discount on their BOM.

Please browse through the categories below and use our online shopping cart to make your order. Completed orders will be processed as soon as payment is made to Microscale. Packages will be delivered to the customer by DHL or via other special arrangements, such as ABC transport.

Adeyinka olu: @princejude. Please where are you from? Are you from lag? I need you to teach me this micro controller stuff. Am an electrical and electronics engineer. Graduated last year. Please i wil be looking forwad to hearing from you

Adeyinka olu: @prince. Please do know any body that you can refer me to in lagos state. Who can be of assistance for me. I need to know this micro controller stuff.

Adeyinka olu: @prince. Please do know any body that you can refer me to in lagos state. Who can be of assistance for me. I need to know this micro controller stuff.

hopefullman: @princejude.pls do you have FLC meter(frequency inductance capacitance) and how much is it.thank you.

princejude:

We don't have ready made but we can build one for you. We designed one as a student project for one of our client recently.
