Elektor MultiCalculator Kit (based on Arduino)

  • BrandElektor Labs

Description

The Elektor MultiCalculator Kit is an Arduino-based multifunction calculator that goes beyond basic calculations. It offers 22 functions including light and temperature measurement, differential temperature analysis, and NEC IR remote control decoding. The Elektor MultiCalculator is a handy tool for use in your projects or for educational purposes.

The kit features a Pro Mini module as the computing unit. The PCB is easy to assemble using through-hole components. The enclosure consists of 11 acrylic panels and mounting materials for easy assembly. Additionally, the device is equipped with a 16x2 alphanumeric LCD, 20 buttons, and temperature sensors.

The Elektor MultiCalculator is programmable with the Arduino IDE through a 6-way PCB header. The available software is bilingual (English and Dutch). The calculator can be programmed with a programming adapter, and it is powered through USB-C.

    Mooie en betaalbare elektronica calculator! Die direct aktief is na inschakelen.

    Vandaar dat ik hem kocht in vergelijking met de altijd langzaam opstartende android smartphones en tablets met hun elektronica apps.
    Alleen las ik dat er nog een berekening aangepast moet worden in de ino file omdat anders uitkomsten niet correct zijn.
    Het uitprinten van de keyboard toetsenaanduidingen op juiste grootte was nog een dingetje en kan alleen als je beschikt over Photoshop of vergelijkbare tool om de juiste 10mm x10mm afmetingen uit te kunnen printen. (Bij 40 x 50 mm voor alle knoppen en die dan uitknippen en in de transparant houders plaatsen).
    En in de instructie bouw handleiding staat C3 hoogstwaarschijnlijk met zijn polarisatie verkeerdom afgebeeld. (uitgaande vd weergegeven tekstzijde op C3).

    Mogelijke verbeteringen

    The USB connector is removed when the USB is unplugged.
    It is difficult to ajust the keyboard in the black frame even if the switches are soldered very carefully

    Snel gebouwd, maar de toetsen waren wat lastig in de behuizing te krijgen en dus blijven zo ook wel eens "plakken".
    De functies zijn goed en eventueel uit te breiden.

    Le calculateur est bien conçu, il est dommage que le logiciel ne soit pas au top,
    Comme signalé sur le site, j’ai eu des problèmes avec 2 touches la racine carrée et la flèche qui sont gérées par une entrée analogique et sur mon kit, je ne sais pas si d’autres clients ont eus le même problème les seuils de fonctionnement n’étaient pas correct.
    Après modification du soft tout va bien

    Easy to build

    Leuk hebbedingetje. Snel gebouwd.
    Enkel de toetsen in het plaatje krijgen was wat moeilijk…
