More than a Mosfet, this is the only microcomputer you will ever need for your AEG and at a great price.
Now everyone can have a Mosfet, no wiring no installation, just plug and play, read on for more information and check out the videos at the end of the page.
AEG Burst Wizard LV Userís Guide
The Burst Wizard is a microcomputer based product, please treat it well and donít spill any water on it.
Use a small Philips screw driver to assist with turning the burst count selection knob. The black knob (POT) at the side of the board is relatively fragile, so be gentle when turning it with a small screw driver. For the Burst Wizard to work, simply connect it in-line with your original battery to AEG connection. For the AEG Wizard to activate the LIPO protection function, always use it with a properly charged LIPO battery (11.1V and 7.4V are supported). If the LIPO battery used, is not charged to at least 80% first, then the unit will not always protect the battery by shutting off the AEG.
If LIPO battery is used, we recommend that you do not disconnect or exchange the battery once the AEG Wizard is installed for the duration of the whole discharge cycle. In other word, use the battery from when it is fully charged to when the AEG Wizard shuts off your AEG for low battery protection. The AEG Wizard relies on the initial voltage to determine whether it is a LIPO or not, if you plug and unplug all the time, the Burst Wizard may not enable the low voltage detection and shut itself off. That is the only feature that you may lose.
FOR SAFETY PURPOSES, ALWAYS UNLOAD YOUR AEGíS MAGAZINE BEFORE CONNECTING THE BATTERY TO DO THESE STEPS ON THE AEG BURST WIZARD:
1) POT (knob) turned fully anti-clockwise before connecting the board to the battery:
Sniper mode: The AEG Burst Wizard will enforce a 1 second delay after each burst. You need to turn the POT clockwise and pull the trigger at the same time to tune to your desired burst count. You should feel the delay of about 1 second between bursts.
2) POT (knob) is not turned all the way to the clockwise or anti-clockwise position before connecting the board to the battery:
Regular burst mode: Set the burst count just like in mode 1). Turn the POT to your desired burst count but without a sniper delay.
3) POT (knob) is rotated fully clockwise before connecting the board to the battery:
ROF adjustment mode: At this position, the AEG Burst Wizard is a simple MOSFET device that has soft start and current limit protection for your motor but has NO burst control. Now, when the POT is turned anti-clockwise and the trigger is pulled, you will realize that the ROF has been changed. Set it to where you want. Please do not overdo it and potentially overheat it by turning the ROF too slow. Please be realistic! We prefer that you operate AEGs in this mode only when they are loaded so that you won't go firing 100s of rounds with no BBs. The MOSFET and the small board really appreciate your cooperation.
Now, the AEG Wizard is ready to operate. You are welcome to fire at will! You don't have to finish the burst round before releasing the trigger! Just pull the trigger anytime or anyway you want and the AEG will fire immediately. But if you hold down the trigger at any time, the predefined burst count will be fired and then the AEG will stop immediately. You have one second to release the trigger to prevent it from going into full auto mode. (You can lock out this feature. See the LV feature Userís guide)
If you are using the AEG Burst Wizard in the normal Regular Burst mode, your burst count setting will not be lost by disconnecting the power to the unit as long as you are using the same type of battery and the same AEG. For the other two modes, sniper mode and ROF adjustment mode, you have to reprogram it as explained earlier every time battery power is lost to the unit.
During the end of the battery discharge cycle, if the shot count is a little bit off, you may have to readjust the count or replace the battery with one that has been freshly charged.
LV Feature Userís Guide
To activate the LV functions: First plug your Burst Wizard into your gun. Then plug your battery into the Burst Wizard and pull and hold your AEGís trigger within 5 seconds until the Burst Wizard announces (vibrates out) the battery voltage. The first vibration always represents 6.0 volt. Vibrations that are 0.5 second apart represent 1.0 volt increment. Vibrations that are 0.25 seconds apart represent 0.1 volt increment.
For example, a 9.6 volt battery will be vibrated out with 4 vibrations 0.5 second apart and 6 vibrations 0.25 second apart. ( _ _ _ _ _ _ _ _ _ _ )
The full-auto, non-stop firing function is disabled after the voltage is announced. Now, the trigger can be released and you can continue setting up the Burst Wizard as explained earlier.
Trick: If you just want to know the battery voltage but still want the full-auto function, you just have to unplug the power to the battery for 1 second after the LV announces the voltage before plugging the battery back in. Then wait for 5 seconds or more before pulling the trigger or turning the POT on the unit. Now, after a burst round firing, the Burst Wizard will go into full-auto if you still hold on to the trigger for one second or more.
AEG Burst Wizard special features:
1) Allows special burst mode firing: User selectable from 1 to 7 shots. Shot count is easily adjustable by turning the POT (knob) on the circuit board. Accurate timing resolution! For a 25 rounds per second AEG, you get a 1/20th of 1 shot timing adjustment to ensure an accurate shot count setting and allowing the piston and the spring to return to most relaxed position all the time.
2) Enforces LIPO battery low voltage protection. Prior to disabling the firing function, the AEG will vibrate when the trigger is pulled to inform the shooter to change the battery. The AEG will stop firing when the battery reaches its critical voltage.
3) Works for LIPO, NIMH and NICD batteries at voltages of up to 16VDC and up to 80A.
4) User set sniper mode for 1 a second dead zone after each firing. This feature enhances the fairness and competitiveness of the game! The shooter has to aim at the target much more accurately before pulling the trigger; otherwise the target may disappear before the AEG can be fired again. Thus helping to train the shooter to make better shots in the future.
5) If sniper mode is not enabled, the trigger can be pulled immediately and released at any time. But if the trigger is held down, the preset burst count will be fired and the AEG will stop shooting immediately when the burst is complete.
6) Resumes back to full auto if the trigger is pulled and held for more than 1 second after the previous burst has been completed. Releasing the trigger will immediately stop the firing. (The new LV has an option to disable this feature.)
7) Trigger Switch arching reducer feature by allowing high current to pass through the switch only when it is well engaged and remove current from the switch long before the user disengages it. Soft starts the motor every time the trigger is pulled. This feature extends the life of the gearbox and the motor by not driving them too hard but you won't feel any sluggishness at all.
8) Actively brakes while in burst mode after each burst has been fired. Helping to extend the life of the gearbox and to give better trigger response. This feature also ensures that the shot count be very accurate during the whole discharge time of the battery.
9) No modification to your AEG is required. It is in-line with your battery and AEG connection.
10) Very compact in size. Board size is only 2.25" x 0.65"W L x 0.4" H and fits into most AEG battery compartments.
11) Pure MOSFET mode with ROF adjustment from 100% down to 50% or even lower.
12) Announces the battery voltage at power up. Accuracy is +/- 0.1 volt (LV function)
13) The AEG Wizard consumes very little power and will not drain your LIPO battery even if you leave it connected overnight before the game. As a matter of fact, it will take as long as 62 days for the AEG Wizard alone to drain down a 1000mA hour battery! The normal leakage power just from the battery itself is more than the draw from the AEG Wizard.
We do not recommend that you leave any battery in your AEG over night
If you ever need to replace the connectors that come with the AEG Wizard to match with the type on your AEG (for example to Deans type connectors), BE CAREFUL to observe proper polarity and destination. The RED is always the + end and the black is always the Ė end. The Burst Wizardís connector that the battery plugs into is always a male type connector (with a locking latch on the housing). And the Wizardís connector that connects to the gun is always a female type connector.
The LONGER pair of wires should go to the battery connector side. The SHORTER pair of wires should go to the AEG connector side. Reversing any wires or destinations will burn your AEG Burst Wizard beyond repair!!
IT IS NORMAL FOR THE BOARD TO RUN WARM DURING USE, THE BOARD IS DESIGNED TO HANDLE IT
INFORMATION ON MINI TAMIYA CONNECTORS
This type of connectors is rated at only 15 amp maximum current. Since a typical AEG with an M120 spring draws between 12 and 15 amps of current from your battery, a near-perfect connector mating between the female and the male side is important to deliver the power, allowing the battery to have full discharge voltage range and prolong the life of the connectors. Especially for a 9.6V NIMH or lower, if your AEG side connector (or BW battery side connector) is loose (typical condition after prolonged plugging and unplugging of the battery to it) you need to use a metal pick or tweezers to return the receptacle hole back to its original size before connecting your AEG to your battery or BW LV. Otherwise the useful discharge range before the AEG stops to work because of insufficient power to the motor will be significantly shortened. In other words, the motor will not move or will just give you a clicking sound. We recommend serious AEG players to convert all connectors to DEAN connectors as they are rated to 50 amps and are quite small in size andare easy to use.
NEVER REMOVE THE FUSE IN YOUR AEG. THE BW DOES NOT REPLACE YOUR FUSE.
