Un transiluminador es un instrumento utilizado en experimentos de biología molecular principalmente en procesos de electroforesis en aplicaciones de PCR, clonación, secuenciación o detección de ADN. Su principio se basa en transmitir luz de longitud e intensidad específica a travez de una muestra, lo cual permite visualizar proteinas específicas o ADN.
Para efectos de la instrumentación, consiste en un dispositivo que controla una gran cantidad de LEDs. De este modo, el dipositivo debe encargarse de generar los voltajes de operación y la corriente de los LEDs. Las variables objetivo para ser controladas son:
- voltaje de operación.
- Intensidad de iluminación.
- Tiempo de exposición.
En algunos dispositivos más complejos existen variables como tipos de curva de iluminación, o algunos cuentan con cámaras para la obtención de imagenes en el dispositivo mismo. asdavsd
Requisitos del dispositivo.
El dispositivo a desarrollar debe contar con las siguientes caracteristicas:
-
Alimentación de entrada de 12V. De esto se desprende que el dispositivo debe contar con un regulador DCDC tipo boost para los LEDs.
-
Capacidad de controlar diferentes configuraciónes de LEDs de salida.
-
Control de intensidad de los LEDs por medio de un control lineal de corriente.
-
Driver de corriente de hasta 1A por canal.
-
Capacidad para controlar de forma simultanea 2 canales.
-
Lazo de control para monitoreo y calibración de intensidad luminica.
-
Microcontrolador integrado.
-
Modo de operación manual, stand-alone con curvas pre-configuradas o modo de conexión a un host( pc o web app).
-
Monitoreo de la temperatura de los LEDs y sensor de temperatura externo.
-
Interfaz de usuario por medio de panel y pantalla OLED.

Questions
How big is the Transiluminador PCB?
It measures 90.4 × 88.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Transiluminador use?
104 parts, built around the CH340C, ESP32-WROOM-32D, MCP4728-E/UN and TLC272CD. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Transiluminador KiCad files?
From the iowlabs/TransIluminador repository on GitHub, at the commit this page was made from: the board is electronics/controlador/Transiluminador.kicad_pcb and its schematic electronics/LEDs/LEDs_10x10/LEDs_10x10.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Transiluminador design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
