inigohe Posted January 24 Posted January 24 (edited) Hi...Im trying to renew old fashioned rudder peddals... Simped Vario F16 from Hoffman´s, replace whole electronics whith an 10 bits system like ProMicro with Mmjoy2, and remove the oldest 4 bits system with gameport connection able only to connect to Hotas Cougar from Thrustmaster. Let me know if you have some links, content about those kind of hardware modification . My idea its use magnetoresitive sensor for the main axis and use load cells with an analogic amplificator to each toebrake, the connect three to Mmjoy2. Best regards and thx for your attention, Ignacio from Spain. Edited January 24 by inigohe Add detail of old electronics Quote
inigohe Posted January 24 Author Posted January 24 The really strange its... Come two wires from toebrakes... When standard hall effect sensores have three wires as analógic devices like potentiometers has!!!. Seams to be a diferent kind of sensors like switches o similar stuff. Quote
inigohe Posted January 24 Author Posted January 24 (edited) The sensor works fine with Mmjoy2 then the toebrakes are working whith Presure sensors... 2wires...then whith an resistor and a capacitor to gnd I can connect second wire to an analógic pin of Mmjoy2 as I did whith the hall effect sensor.

The 90s: 2-Wire Hall Sensors (4-Bit Era)- Technology: Analog current modulation.- Resolution: Very limited (4-bit = 16 discrete steps).- Precision: 360° / 16 = 22.5° per step.- Interface: Required an external ADC or comparator network (e.g., LM339) to convert current into binary logic for the CPU.- Use Case: Basic position switches and simple industrial counters. 1. Années 90 : Capteurs Hall à 2 fils (Ère 4 bits)- Technologie : Modulation de courant analogique.- Résolution : Très limitée (4 bits = 16 niveaux distincts).- Précision : 360° / 16 = 22,5° par pas.- Interface : Nécessitait un CAN externe ou un réseau de comparateurs (ex. LM339) pour convertir le courant en logique binaire.- Usage : Interrupteurs de position basiques et compteurs industriels simples. 2. Modern Era: TLE5010 + Arduino- Technology: GMR (Giant Magneto-Resistance) digital sensor.- Resolution: High fidelity (12-bit = 4,096 discrete steps).- Precision: 360° / 4,096 ≈ 0.088° per step.- Interface: Digital via SSC/SPI protocol; Arduino reads sine and cosine values directly.- Processing: Arduino uses the atan2 function to calculate the exact angle in real-time, impossible for 4-bit processors. 2. Ère Moderne : TLE5010 + Arduino- Technologie : Capteur numérique GMR (Magnétorésistance Géante).- Résolution : Haute fidélité (12 bits = 4 096 niveaux distincts). Edited January 25 by inigohe Quote
inigohe Posted January 25 Author Posted January 25 I will show whole job soon... But seams finally will not upgrade to Tle5010. Whith original hardware its enough to have a renew Simped Vario F16 Usb. Quote
inigohe Posted January 26 Author Posted January 26 (edited) Esquema electrónico – Toe Brakes con FSR y MMJoy2 Este documento muestra un esquema visual y conceptual del circuito usado para conectar sensores de presión tipo FSR (Force Sensitive Resistor) a MMJoy2 para simular toe brakes en simuladores de vuelo. El diseño es válido y comprensible tanto para personas con conocimientosde electrónica como para principiantes. Conceptos clave usados en el esquema • FSR: Resistencia variable dependiente de la presión. • Pull-down: Resistencia conectada entre la entrada analógica y GND. • Divisor de tensión: FSR + resistencia pull-down. • Filtro RC: Resistencia + condensador para eliminar ruido. • Entrada analógica: Pin A0 / A1 de MMJoy2. Funcionamiento resumido Cuando no se pisa el pedal, el FSR presenta una resistencia muy alta y la resistencia pull-down lleva la entrada analógica a 0V. Al aplicar presión, la resistencia del FSR disminuye, el voltaje en la entrada analógica sube progresivamente hasta ~5V y MMJoy2 interpreta ese cambio como fuerza de frenado. El condensador filtra microvariaciones y elimina vibraciones indeseadas. Notas prácticas • Un circuito idéntico se usa para cada pedal (Left / Right Toe Brake). • La resistencia y el condensador están en paralelo entre A0/A1 y GND. • El filtro RC no introduce retardo perceptible en simuladores. • Este diseño es el más utilizado en pedales DIY con MMJoy2.
