    Default RoboShop @ Ri , your wishlist ??? ...

    Soon ill start a small RoboShop @ Ri. My plan is to make things affordable and available.

    We are mainly interested in selling boards , as components a lot of other sites sell and they are priced decently.

    So i would welcome ideas from all of you guys to tell what you think is required and would sell .

    Here is the current approx price listing of items planned

    AVR USB Programmer - Rs 200
    Arduino Serial ( ARP 1.0s ) - Rs 300
    Arduino USB ( ARP 1.0u) - Rs 400

    You think something would sell and others are overcharging please let us know ...

    PS : For those not clued to ardunio its a awesome development platform based on At Mega series of uC's.

    @vikas: I loved your Idea from the start! However, the selection that you have put up is relatively incomplete. Arduino boards are relatively incomplete without the basic shields. Here are some basic shields I think you should keep.:
    1) Motor control shield (2 DC Motors) + Servo Motors.
    2) Motor control shield (2 Stepper Motors) + Servo Motors.
    3) LCD (16x1, 16x2, 16x4 etc.) Shields.
    4) Ethernet Shield (based on commonly available ENC28J60 in DIP package).
    5) GPS Shield
    Plus maybe something like this (clickie)

    Regards,

    Debu

    We have the following shield in the plan

    Motor Shield - L293 based + Servo
    Proto Shield
    Serial LCD's
    A starter Kit.

    Ethernet and GPS we would maybe introduce later on. Slowly we will increse the item in the shop.

    I also like your Idea very much.

    We are mainly interested in selling boards , as components a lot of other sites sell and they are priced decently.
    I would sugget keeping the commoly used parts/componets as well, even though they may be available at decent price else where, this will save the extra shipping charges incurred by getting components from diffrent places.

    Make it "one stop shop" commonly used items.

    Gradually this can be turned into something like sparkfun (Although I have never analysed their pricing ).

    If you decide to keep the commonly used items we can decide upont the list.

    Well this is just my suggestion, deciding upon the feasiblily is your take.

    Make a ready to use RF module with documentation... it will sell like hot cakes also a wireless serial communicator... been seeing a lot of demand for that lately on the forums.. gps is too advanced for now and I dont think "most" students use the boards for anything more than entering competitions..

    Also, a bunch of engineering schools are popping up out of nowhere and they all have 8051 used in labs.. how about something affordable based on 8051 on which students can practice their stuff.. means business...

    But on the other hand, how many students actually work in college

    Somehow i dont think 8051 is any more affordable than AVR or PIC .

    Its just that Indians are stuck with the old legacy stuff.

    c2051 costs about Rs 30 and Atmega8 costs about Rs 50 , But price / performance difference is no where comparable.

    Yep we plan to introduce affodable transceivers .

    Even if 8051 chips like AT89s52 etc are no where comparable with AVRs they have very large user base coz must college have 8051 in course but not AVRs or PIC.
    Also many industrial designs i know are based on AT89S52.


    Not only Indians are sticking to old technologies, I recently supplied my USB 89S52 programmers to a company in UK. They have some industrial automation based on AT89s52 which they wanna field update by laptops.


    So 8051 is still very hot!

    Servos from Hitech, Futaba. Sensors like SRF05, Sharp IR. Geared motors (plastic and metal)with wheels.

    Thanks,
