I must not be the only one who wanted a tracer unit that was integrated into the silencer making your gun about 3 foot long so I was looking up Hop up tracer units and if you want to buy one of them its like £ 30 for the special hop-up * bull shit* and £40 for the led unit to go onto your special hop up all sounds like such shit. So I went about researching and making my own cos £70 for a tracer unit is a bit crazy. Research So I went about researching it and a lot of people have done Hutu unit but don't document the process well and all have different setups so I'm just documenting the one that worked best for me. LED LED wise I used 3mm UV LEDs which have a common brightness which is about 3,000mcd which in common I couldn't find anything higher but if you could find a high mcd then I would say get it. It would be hard to as UV light doesn't register on the scale the same way. I have heard to use 12,000 mcd blue led but they didn't perform as well as the UV LEDs the reason for this is the substances the BBs are coated in react to UV light very well as you can see from the picture below. My chose is 3mm UV 3,000 mcd BBs (UV light on bb picture ) BBs BB colour is up to you but I tested Blue, Red and Green and green was the best one by far it gave the best contrast in most settings in most conditions obvious in the sunlight no matter what colour it's very hard to see. so my chose is Green BBs Equipment Now that you know what LEDs and BBs to use it would be great to know what sort of equipment you would be using, Hot Glue Gun Black glue sticks Dremel / Rotary tool Rotary cutting disc Clear coat nail polish JST wires Drill 3.1mm Drill bit Some Wires Super Glue 6mm Dowel UV led ( non diffused ) Resistor A battery capable of 30 amps that's all you need Prototype 1 So on the prototype, I used two LED on an old plastic G&G sr25 to know what I needed to do, So I drilled two holes using a 3.1mm drill bit for the hop up once this was done. I then worked on the LED you to want to trim this down as low as you can without touching the element this will get a cloudy white colour an easy way to bring the clearness back is to apply a thin coat of clear coat to the LED leave these to dry I then insert the dowel into the bottom of the hop up so the led wouldn't interpret the path of the bbs I then used a little bit of super glue to hold the LED in place on the edge of the led so it doesn't diffuse the colour. The then wired LEDs up in series so connecting the positive to the negative side and adding the JST lead on hot glueing everything down to stop any light bleed out the side of the gun The BB glow was a little bit dead the glow was really weak so I would need to wire them into parallel and add in a resistor as my first prototype lasted 48 hours before the first led failed as my battery was delivering over 38 amps. Parrel or Series So after a little research, I realised that in series the battery voltage was cut in half for the LED so if I added more LEDs it would just decrease the voltage for each LED reducing the brightness so I would need to run it in parrel and so all the LEDs will get the same voltage allowing for a better overall performance so I did a small test to compare brightness. In Series In Parrell From this small test you can see the LED in Parrell are a fair bit brighter so for the second mockup I will add the two more LED brings the total to 4 and add in a 320ohms resistor. Prototype 2 For the second prototype, I added two more LEDs to bring it to 4 ass you can see comparing it is a fairly big difference in brightness I also added the resistor to the end of the positive LED leg that goes into the JST plug this limited the position I could put the cables into feed the through the gearbox to the battery into pistol grip. I know what to do for the final unit I will be making. I had an idea of drilling into my prowin unit but I drill wasn't strong enough neither was my drill bit as one warped under the pressure and heat generated but the concept carried over. Final HUTU unit for the final HUTU unit, I used an SHS plastic hop up which is the same as the Prowin and SHS aluminium, So I drilled out the led holes using the 3.2mm bit the same as the first prototype, cut down the LEDs and clear coated the same way. Glued them in the using super glue wired them up in parallel and added the JST plug onto the end. I then added the resistor into the extension cable so it gave me way more space to flex the cable giving it a nice compact look and allowing the hop up unit to fit right and compact without getting in the way Once this is done I then connected everything in and made a bypass cable that allows me to run the Wolverine trigger board and Hutu of the same battery the one I'm using that give me a nice smooth 30 plus amps that give the Hutu enough amps to run at full brightness and the trigger board to run as it should. Turnigy Graphene 950mAh 2S 65C. Below is the Hutu all wired in and Video of it firing. The video isn't the greatest quality so I may change it if I can get a better video recorded.The green glow is from the tracer round inside the hop unit. Video Slow Mo Video AEP tracer Video Any questions let me know. I will be working on an AEP pistol internal tracer unit I posted the info for this in my Cyma 030 / TM g18c upgrade thread.

Just picked this gbbr up for a steal

Soooooo... Yall remember that Vector that I may be able to get for $600?... Well, was browsing the local sales page on one of the lesser known apps (like Craigslist), and came across one for $200 with two mags... Guess who's just decided to spend $200? haha

So... I actually ended up getting that p* refunded because a HPA Scorpion Evo (with tank and line) popped up and I just thought "well... I want that more than an M4" (which is true, only I couldn't afford a scorpion when I started airsoft) So yeah... Change my last post to say I'm nursing the wound from an upgraded HPA Evo, and mag pouches 😂 One tank leaks but it's probably just an o ring... Not sure if the case is included or just for showing photos 😂😂 Also add on buying an extra 3 mags.

I keep saying I’m gonna build one of those glass desk PC’s where it’s all looking pretty underneath

Did anyone else read that as platecarrier?

At least you probably use it. I built a water cooled i7 with a gtx 1070... don’t think I’ve played anything more strenuous than solitaire on it 😂

Stop it! I swore I’d never buy a kwa. Stop making me look at the beautiful thing!

Take a Number and get in the queue ! 😂😂😂

100m Laser line measurer. Just made Tippmann M4 my into a DMR, maybe I'm being optimisitc 😀

The gang is all here! PTS GBB Pmags arrived quicker than expected. PTS Masada GBB build completed!

I never bat and eye lid when I spend on airsoft, no matter the cost, but anything else... I just spent 1.7k on PC components and I am just thinking about how much airsoft stuff I could have bought 😥 All the shiny stuff 😭

If I close my eyes when listening to that, I see Slim in my head.

I`m now the proud owner of a KWA vector 😍 On the outside its definitely not the most pristine example out there but for the price who can complain, i plan to use it in CQB anyways so its bound to get dinged up here and there so a few minor marks doesn't matter too much. Already stolen the sight off of one of my other guns just for the time being until i can get my hands on a holographic sight so its a bit funky at the moment. I've already gone and installed the maple leaf CNC hop adjuster (lucky find on that online and in the UK!!) on order is a silencer adapter and the hop rubber with tensioner to go with the ML unit i have already, Also with some advice from RDB I`ve ordered all the parts ( I think at least 😂) to make myself a remote HPA magazine to give me somewhere in the realm of 2500 rnds.(that should be fun). So far im super impressed with just the hop adjuster made such a difference to my range with some 0.25s (struggles with anything more at the moment hoping the rubber and tensioner fixes that so i can use .28s like in my scar and g18) before I couldn't quite get the hop right for the 25s. Hoping to get a barrel for it aswell to extend out into my silencer but as im finding not the easiest thing to find it seems !!! Big thanks to @rocketdogbert for his help and guidance with my new gun and for the parts he had locally to me without having to scour the country for them. 👍👍

2 x MP7 mags... then realised they are for a AEP not a GBB (no wonder they were stupidly cheap) DOH!!

She's all dressed up ready for The Mall on Thursday... Holo, torch/laser combo and tracer unit. Love the TM HC 🙂
