Choosing a selection results in a full page refresh. High-end AEGs can be complicated with low resistance wiring, MOSFET switches, and electronic triggers. thanks for bringing it up. This will improve your airsoft gun's battery life and internal electrical durability, along with adding enhanced firing capabilities. The LED shows the sketch is programmed OK, so it must be a hardware issue. Check them out below. I doubt you'll find the right parts from that, it's only a couple dollars to buy the parts anyways. VGS =10V;ID = 40A <<<<<< this requires 10v to get the stated resistance. Use left/right arrows to navigate the slideshow or swipe left/right if using a mobile device.

This is a very powerful gun, hence the need for the MOSFET in the first place. the chart above indicates it can pass 10A at 5V. The MOSFET unit is pretty much an electrical switch attached to your AEG airsoft gun's wiring. Unless the device is fully on it will have more resistance and could overheat. on the other had, if the mosfet were between the supply voltage (e.g. For a better experience, please enable JavaScript in your browser before proceeding. We make great efforts to maintain reliable information on all airsoft and tactical products presented on High Speed BBs. The basic understand of what a MOSFET does is that is handles electrical loads and current in optimized ways by routing electricity through a series of circuits with electronic switches. Yes it can handle 40 amps no problem.

You can make your own MOSFET switch with components, wire, and a soldering gun. No way can it be fully on at 4.5V if that's the case. wondering how you did to "fryed" them. Can you make it so there is a variance in voltage so there is no complete circuit until it reaches, say, 7V, by which time the trigger has stopped bouncing? However, they do not have the same connective capabilities as their advanced counterparts (like Bluetooth). i used a mtb40b10e (40A 100V) to drive a small 12V DC motor and it seemed to work with the gate at 5V (i.e. MOSFET switches modify the circuit found in AEG airsoft guns described above by adding a MOSFET unit which connects the battery and motor directly and by passes the trigger (while still being activated by the trigger). I also know that the Battery can safely put out a maximum of 65A for an extended time, though the charge will not last long in that situation. No way can it be fully on at 4.5V if thats the case. The airsoft product offers that appear on the website are from respective airsoft industry companies, suppliers, and stores from which High Speed BBs receives compensation. All the stuff about contact bounce and 555's and other oddball stuff is hokey poke. guess ive never had a problem is the mosfet that had a gate threshold voltage that was higher than what I was driving it with and had a higher Rds than I could work with.

this has a pretty low Rds (< 0.01) very high current (80A). Min Max If the threshold voltage can be as high as 4V, that means the device is fully off below 4V. VGS(th) Beware of the threshold voltage rating - its not relevant to using a MOSFET as a switch. Is there a safer way to go about protecting the chip while still providing adequate cooling? now when i connect the motor on semi it acts like a normal switch?

I having the issue of the FETs getting really hot as the replica is fired, until it finally locks closed and burns itself out. I have a dead graphics card I can salvage parts from, I Googled airsoft mosfet schematic and got this, http://unconventional-airsoft.com/2009/08/26/how-to-make-a-basic-mosfet-switch/.

Maybe it could be better. does it need to be if you're driving a small motor that draws maybe 200 ma?

2022 HighSpeed BBs. For all things airsoft. it looks like you're diagram is correct. However, the product information listed on highspeedbbs.com is provided without warranty. See the unconventional airsoft link restartgaming posted, You can order MOSFET parts from Digikey for about $5-10. it should be safe unless you flinch on the trigger and try to shut off the mosfet with a hundred amps flowing through the motor. You might think that, youd be completely wrong. hey guys so i got the mosfet and wired it all up how i have in the picture. 12V) and the motor and the gate set to the supply voltage, then the source would be slightly below the supply voltage.

I would guess that it would still turn on at a lower gate voltage but with a higher Rds. isn't it true that as long as the gate voltage is above the source voltage, the mosfet will conduct? Concerning amperage, I know for a fact that the gun pulls a sustained 2A-35A draw depending on the position of the gears. In a standard AEG airsoft gun wiring harness setup, the AEG's trigger, battery, and motor are all connected in a "circuit" by the connecting wires. Highspeedbbs editors select and review airsoft products independently. The MOSFET setup is pretty simple. Press question mark to learn the rest of the keyboard shortcuts. (which i believe you show). Look at RDS(ON) in the data sheet and see if there is a rating for the voltage level you will be using i.e. mosfet resistance is often measured in milliOhm, meaning that a mosfet needs to dissipate very little power when passing relatively large currents. Won't pass the 24V threshold: Even considering the volatility of Lithium Polymer batteries? i had never heard of a logic level mosfet. connecting an Arduino digital output to the gate and setting it HIGH should make the mosfet conduct and drive the motor. If you want to better understand MOSFET switches, we should talk about the different types available. the schematic below shows common use of a mosfet to drive a motor. ok guys so my goal is to use an arduino with a mosfet to control a motor. MOSFET stands for "metal-oxide-semiconductor-field-effect-transistor". The mosfet connects the motor to ground. this is all very interesting and I understand that there are subtleties to this that I don't understand. Here's another way to look at it. Could be power related or EMI related - switching big currents is prone to induce spikes into nearby wiring and/or knock the supply voltage down briefly. with 2 switches For an airsoft RIF, so i want to press say switch one to make the motor do spin once. http://unconventional-airsoft.com/wp-content/uploads/2009/08/Simple-MOSFET-Setup-2009-06-22.jpg, http://www.chaolimotor.com/EN/product.asp, http://www.infineon.com/dgdl/irlb3034pbf.pdf?fileId=5546d462533600a40153566027b22585, http://www.airsoftguns.ie/2857-thickbox/ad-classic-aeg-standard-motor-long.jpg, airsoft trigger dual mosfet long wires.png, http://m.ebay.com/itm/321057005593?_mwBanner=1, Arduino to Airsoft Gun interface Critique, converted atx supply to power multiple 9.6v 1600mah airsoft guns. JavaScript is disabled. gcjr: VDS =VGS;ID =250A <<<<<< next to nothing for Drain current 250A. i appreciate the comments. maybe before testing with a motor, use and LED and 1k resistor. Automatic electric airsoft guns (AEGs) are high-performance airsoft guns. i'm surprised i couldn't find a schematic for the Airsoft PicoSSR. Please read the rules, Wiki/FAQ, and use the search bar!

The airsoft guns using the basic switches can still be setup for burst timing once they are manually programmed. Two wires from the motor to the mosfets will help balance the current because the wires have a little bit of resistance in them. Drop-in MOSFETs include several different types form more advanced wired-in solutions to simple plug-and-play units attached in-line with the airsoft gun battery connectors. when i press it in the motor runs intill i lift of the button, when i press the full auto button down it pulse's like it should, what could the cause be? Gate threshold voltage is the level where the MOSFET is OFF. if i use a led, the code works fine, turns on then off in "semi" and in "full auto" it blinks on and off, this is what is suppose to happen. ClassicArmy M133 With 4 Tracers what do you guys think Cry all you want, it won't remove the carry handle from NFTs arrive to airsoft extremely late to the party. Press the space key then arrow keys to make a selection. i have no basic electronic knowledge, so if anyone could help me getting power to the arduino is no issue, i just need help with the wiring. Okay I'll make it and see how it performs. i had never heard of a logic level mosfet. While this works, it is not the most efficient setup. Here is a decent logic level MOSFET, but there are many others. I would guess that it would still turn on at a lower gate voltage but with a higher Rds. thanks for bringing it up. why would the gate need to be above both the source and the drain voltage (you said 10-12V)?

Note that in that diagram the MOSFET shown, STP80NE06, is not a logic-level MOSFET and wouldn't work properly from a 5V Arduino. I am interested in part numbers for mosfets, or maybe just fets that at adequate for the small motors i'm using and can be used for braking.

For most MOSFETs that's 10 to 12V. Basic MOSFET switches have the basic setup and electronic load controls found in a MOFSET system. Last update on July 21, 2022 // Source: Amazon API.

Well no but I'm curious what you guys are using. it was more on than off). assuming my numbers are correct, what do I need to do to make the system work? In full automatic firing mode, they can shoot a lot of airsoft BBs really quickly. Many of the modern MOSFET switches on the market are advanced versions. The first part to understanding MOSFETs is learning what it is and what it does. 8.5 10 . so despite that fact that the gate threshold voltage < 5V, this is not a logic level mosfet because Rds would be too high.

that current can create high voltages. Find an AEG airsoft gun which comes with a MOSFET! All of these features contribute to the electrical efficiency of the gun, improve battery life (causing a single battery charge to last longer during airsoft games), and increase the gun's durability. Let's talk about MOSFET's and their uses in guns. of course this is not an ideal part for what i'm doing and your comments are making me appreciate that I should find better parts. The actual voltages vary significantly between lots due to manufacturing spread too, so its best not to push your luck. so i can get it to turn on and off with a delay with this code: but it keeps going when the button is pressed, Powered by Discourse, best viewed with JavaScript enabled. Why would power in the diode make the FET get hot? A 10k resistor is often between the gate and source to deplete any residual charge on the gate so that the mosfet turns fully off. Get a IRLB3034, a 2200 and a 100 ohm resistor, and a 5KP18A TVS diode, New comments cannot be posted and votes cannot be cast. Pistol Games are fun, but Reloading Pistols is Just as Press J to jump to the feed. I build little MOSFET systems for Airsoft guns to save the trigger from arching and decrease overall resistance. This setup controls power sent to the airsoft gun's AEG gearbox effectively, efficiently, and reliably. Gate Threshold Voltage The battery is an 11.1V 2200mAh 30C LiPo hobby battery. We may earn affiliate commissions from buying links, which help support our testing. Go by the power dissipation being I-squared-Ron. (diode?). What's everyone's opinion on the Bang Bang rule? Typical threshold voltages for logic level FETs are 0.51.0V. Users should always check the manufacturer's official website for warranties, user manuals, terms (if any), and product details.
