Hop up tracer unit project

Thanka for that Simon thats an awesome resource, can definitely see me buying from them in future. I've done a quick calc and I reckon I'm looking at about 3hours continuous run time from 2x cr2032 batteries..... How that works in practice with volt drop we'll see 😁
-
I haven't calculated it - ideally want to mock up the circuit first and check the current it actually pulls, but based on the LEDs having a typical draw of 20mA and peak of 30mA (as per the eBay sellers description, who knows if that's accurate) and the 2032s being 225mA (ish) it should be a couple of hours at least I'd have thought. If it is going to make significant difference then I may scale it back to 2 LEDs, but would need to recalculate the resistor values. Would you mind sharing the setup of your circuit?

Thanks Simon. Going to take your advice and go for a separate battery pack, going to use a couple of 3v cr2032 cells, which I reckon I can wire to the front and install within the handguard in a way that I can still access the switch. Plus this will make it easier for splitting the receiver in future. Planning to use 3x UV LEDs with 3.6v forward voltage, individually throttled down via 120 ohm resistor. Should be able to get decent brightness and run time, and keep it small and simple. Cost of parts should be less than a tenner, including the "prototype" hop unit

One for the techy guys more than anything I think...... Gonna have a go at making my own hop up tracer unit, to go in my G&G Raider 2.0, I'm planning on wiring it to the main battery tamiya connector. Planning to use a pair of 3.2v UV LEDs for this - I'm aware I'll have to use a resistor to limit the forward voltage. Question I have is am I going to have issues with power surges as the motor fires up? Will I have to also use some sort of diode as a protective measure? What's the simplest way to run the wiring? What size cable should I use?Has anyone got experience doing this?

I was really considering one of these but ended up spunking the extra money on an E&L, had a more basic double bell which my nephew now has, gearbox etc seemed ok for the very cheap price I bought it for.

Ok forget about this thread and came across it searching for other Ak based info.... Thought I'd update to help people out. Seems with this gun you take out the 4 screws in and around the magwell, then you kinda expect the front and rear to split apart, as I believe TM types do. Nay Nay my friends, not yet. If you look at the front sight front the barrel end, you will notice a round pressed in plastic cap, you will need a small screwdriver to pry this off. This will reveal a large Allen bolt head, which runs through the top handguard into a metal lug on the other end, which holds the 2 pieces together. Remove this and the sections will separate apart. Hope that helps someone else and saves them scratching their head for longer than they really need to 😂

Macmillan style sniper rifle, sorry can't remember what make it is. Bolt action, polymer stock with metal action. Comes with Victoptics 4x32 scope which is a lovely clear little scope. Only used about half a dozen times, just sits in a cupboard so seems a shame to keep it. Sorry no postage cause I'll be honest I cant be bothered with the hassle£80

Bought this as a bit of a two prong idea, firstly to have a go with an AK platform gun, and secondly as a learning tool. At the £69.99 i paid for it, I'm not too bothered if I make a mess of it. Trouble is, I am not sure how to go about getting the gun apart. Seems I can't remove the hop up and barrel without splitting the gun (like the TMs do I believe) but even with the screws underneath removed it doesn't seem to want to come apart. Anyone got advice on this please?
