Are UAVs a growing threat?

That's interesting. A small drone would obviously be more susceptible to buffeting by the wind so an INS that didn't need outside reference would be more difficult to implement.

I sporadically mess around with building a 'black box' recorder for my car, one module of which was to have a gyro/accelerometer to measure attitude and G forces. Unfortunately my inner idiot burned up 3 boards by omitting the 5v regulator and connecting them directly to the car's 12v.



The Apache might be a tad excessive now you mention it. :D
On second thoughts helicopter downwash probably wouldn’t be enough to force a drone down. After the turbulence it probably would just recover to its original altitude and path.

One is a gobsh!te. It all worked fine on a breadboard but when I soldered it onto stripboard I messed up. Instead of properly checking, I assumed it was the cheap Chinese board that failed so I swapped it out. And swapped it out again.:redface:
5V regulators don't like 12V, I've made just as stupid mistakes myself, only slagging ya. :wink:

Chris Grayling, UK Transport Secretary, postponed the introduction of new anti drone legislation because of the workload of dealing with BREXIT. BALPA, the main pilots union, and ATC bodies have been highlighting this problem for years but Grayling was on TV yesterday warbling on about how this is a new problem.

Depends on the current that the regulator is handling but most of the 1A 7805s are fine with a 12V input voltage. The 7805 regulators are generally rated for an input voltage between 7.5V and 35V. (best read the datasheets). The higher the input voltage the more heat dissipated via the regulator's heatsink. That's why some of them will need an extra heatsink in some situations. There are other options if that is the case.

The breadboard prototype was powered from the arduino 5v but the stripboard version dispensed with the arduino and used a bare ATmega328. I powered the controller correctly from a 7805 but for some stupid reason I took vcc for the MPU6050 from the 12v input of the car ciggy lighter rather than the output of the 7805.

All part of the fun of learning and the cost is only pennies when buying from China.

Just ban the things except for licensed operators for commercial use .Ensure the few that are licensed have identity numbers like a plane and then introduce crippling eye watering fines for anyone without a license ......

Better that than every fringe protest group or loons shutting down airports at will

I have not been constructing for a while now but you are whetting my appetite just listening to you. Aurdino and raspberry pi were gamechangers without doubt. Smell of solder flux is also addictive :D

You wouldn't be up to the Chinese lads and their back doors. Speaking of back doors there's probably a full report in Beijing as we speak from Baron Von Biffos drone and photos of Lady Von Biffo's drawers being circulated far and wide at a Conference of Party Delegates.

Expect more of this......

A drone attack on a Yemeni government base by the rebel Houthi movement has reportedly killed six soldiers.
The drone exploded above a podium at al-Anad base, in the southern province of Lahj, where high-ranking officers and officials were watching a parade.
Medics said army deputy chief of staff Gen Saleh al-Zindani and Lahj governor Ahmed al-Turki were among those hurt.

Haven’t we seen thousands of deaths already from US drones?

I’m guessing those Houthi lads didn’t glue that together themselves.
We're speaking of different types of drones. Not military drones. Incidentally - and I don't want this to be taken as support for their deployment - military drones seem to have an astonishing rate of clean kills. I mean that in the dreadfully euphemistic sense of not having a high rate of "collateral damage". Figures from Pakistan indicate a rate of around 25% of civilian deaths when they are deployed. 25% is, of course 25% too high, but conventional methods typically involve a bycatch of around 65%.

It's a dreadful discussion. Which way of killing enemies is most clinical.


I'd always feared that young people sitting in bunkers remote from the action and far from threat would be psychologically immune to the dreadful outcomes of their actions, but it seems that that same remoteness is allowing calmness and precision.

The Iranians supplied them or perhaps it’s a locally manufactured copy of an Iranian original....

...but that incorrectly describes the engine as a gas turbine....it’s not. It’s a small petrol engine. It’s relatively low tech but long range but and with a fairly hefty 30kg payload. These things are cheap, easy to operate, very accurate, low risk to the attacker and very difficult to counter.

I’d be sceptical of those low civilian casualties and basically any figures from Pakistan and thereabouts. Two strikes on Zawahiri are reported to have killed over 100 people.

Sniper teams. But that involves a lot more planning, current intelligence and support. It also means getting the team in range of the target and extracting them. With a drone strike, it may be possible to visually identify the target. In terms of conservation of assets and resources, a drone strike means that highly skilled people who have taken years to train are not put at risk. If you want to know where information driven warfare is going, there's a good book called "Rise And Kill First" by Ronen Bergman that details Israeli operations against suicide bombings.

Off topic but anyone know what became of Des Quirell who started this thread?
