(prego i modz di spostare nella sezione adatta, grazie) Non ricordo di aver visto ancora nulla in merito su SAM, ne approfitto dunque per far notare l'uscita di questo nuovo circuito FET programmabile per Gearbox Ver.2, mentre è in preparazione quello per Gearbox Ver.3 Premessa: AWS Airsoft è una piccola azienda statunitense nata nel 2007 che si sta specializzando in quello che essi stessi definiscono Advanced Wargame Systems; Progettano e producono circuiti FET atti a migliorare in modo estremo la reattività del grilletto ed offrire tante altre opzioni a tutto vantaggio di un maggior effetto "realismo" sulle ASG. Ad AWS Airsoft viene accreditata l'invenzione mondiale dell'active breaking per ASG. Il prodotto è stato presentato alla fine del 2011, ed il primo batch prodotto è andato a ruba, esaurito in un batter di ciglio. Ad oggi lo si trova in pre-order presso i distributori autorizzati da AWS, io ne ho ordinato uno e mi hanno preannunciato circa 2 mesi di attesa, data l'enorme richiesta. Il circuito è di dimensioni assai contenute va a sostituire in toto l'interruttore originale che viene azionato dal grilletto delle ASG.

Caratteristiche: Advanced Technology
- Driven by a powerful PIC18LF2321 microprocessor for both speed and versatility.
- Uses the latest in ultra-small SMD components and PCB technology to minimize dimensions.
- On-board supercap and voltage booster allows normal operation under voltage droops as low as 2.5V.
- Short-circuit, under-voltage, over-voltage(ESD), and over-current safeguards.
- Advanced thermal management allows the controller to remain cool under sustained firing.
- Micro-amp sleep current allows batteries to remain connected for many years.
MOSFET Trigger
- Eliminates damaging electrical arcing of the trigger switch contacts.
- Lower resistance compared to mechanical switching, increasing motor current.
- Rated for 100A continuous operation and 400A startup inrush current.
Active Braking
- Eliminates the motor spin-down time, preventing piston over-travel on semi-fire.
- Allows semi-fire to properly reset the piston in any AEG setup, preventing component stress.
- Specially designed to dissipate the braking heat in the wires instead of the controller.
Cycle Completion
- Gearbox always completes a shot cycle regardless of when the trigger is released.
- Allows ANY firing mode to properly reset the piston regardless of AEG setup.
- With the piston always reset, every shot gets the smoothest possible motor startup.
- Allows the anti-reversal latch to be removed (although not recommended).
Burst Fire Mode
- Available burst trigger groups:
- Safe - Semi - Burst
- Safe - Burst - Auto
- Safe - Semi - Burst (no interrupt)
- Safe - Burst (no interrupt) - Auto
- Safe - Semi - Burst (hold for auto)
- "No interrupt" option fires the remaining burst rounds if the trigger is released early.
- "Hold for auto" option allows burst to switch over to full auto if the trigger remains held down.
- Sensor detection of each cycle provides reliable and foolproof burst fire operation (no timing involved).
Semi-only w/ Precocking
- Safe - Semi - Semi (precocked) configuration converts any AEG into a semi-only rifle.
- "Precocked" option stops the piston when ~75% compressed so the next shot is near-instantaneous.
- Offers realism for DMR-style AEGs and compliance to semi-only laws in certain countries.
Adaptive RoF Control
- Adaptive RoF reduction to EXACTLY 10, 15, or 20 rnd/sec on any setup.
- Every cycle runs at full speed and pauses between each shot to reduce RoF.
- Very realistic sound and feel when enabled on very high-speed AEGs.
LiPo / LiFePO4 Monitoring
- Monitors LiPo and LiFePO4 batteries to cutoff power before overdischarge occurs.
- Calculates the cell voltages via the main line, reducing wire clutter.
Serial Comm Port
- Communication port for transmitting signals between custom add-on circuits (ie: ammo display).
- Ouput signals include "shot fired", "trigger pressed", trigger released", etc.
- Input override signal allows add-on circuits to take control of the FET.

Trigger Reliability
- Eliminates the notorious trigger jam on semi-fire, caused by the gears stopping at a certain position.
- Improved cut-off mechanism prevents the fragile cut-off lever from ever breaking.
- Semi-fire no longer requires fully releasing the trigger to be able to fire the next shot.
Simple Drop-in Install
- Drop the FET into the gearbox, modify the fire-select plate, and its ready to go.
- No soldering involved, no wire rerouting, and guaranteed to fit!
