I would say that it seems a miracle there were working badges on time. Both EE and Defcon gave everything they could to make this happen.

But this breakdown in trust, too short timescales, using a new chip, not backing it up with extra funding and choosing this engineering company remains Defcons responsibility for running the project and realising a product.

Without full payment of the development costs, the IP for the PCB probably was still owned by EE and they could have stopped production. This shit show could have been prevented.

DEFCON did not do proper estimation, risk analysis and due diligence with ordering these badges. Also if the cat design and other things were done by the Defcon orga and the electronics by EE, then this already sounds like a complicated mess.

If I look at the Defcon30 badge from 2022. It's the same thing. A small random engineering shop is selected and gets the order. And you get a nice little badge that can do stuff.

For the Dutch hacker camps we look a bit more long term and the engineers and designers have been part of the core team since 2017. And for 2025 we're already well underway.

It depends on the contract. I will never just do a single SOW contract and risk it all. I will do an hourly contract and maybe give a discount if a certain amount of money is spent because things get tough. The client will get an estimation but in this day and age, prices will vary in a few months.

Entropic Engineering should not have gone through with this project on this timescale of 6 months with a new chip. Defcon badge team doesn't know how to properly outsource electronics, collaborate and do risk management.

I recently bought a Brother B/W laser printer. It has duplex, linux support and wifi. Only 81 EUR.

It works great.

"The authors argue that the major problem in many negotiations is that people assume positions that are either Hard or Soft. They suggest that, rather than being either hard on the people and the problem, or soft on people and problem, it is possible to be soft on the people and hard on the problem. They call this approach Principled negotiation or Negotiation on its merits." Getting to Yes - Roger Fisher, William Ury

And my personal motto as a system tester: "It's my job to show that stuff is still broken and tell in it such a way that my head won't be chopped off and people stilltalk to me."

The virtual hells computers were a sort of AWS for civilizations that became space faring and had religions that instituted them. But did not want to run the hardware themselves, because it was too icky. So a whole collection of hells ran on those computers for different societies and different reasons.

The real money for IoT is not in domestic appliances. But in companies that already had networked devices. For example: Logistic, City automation, large medical devices, factories, Transportation and more of these capital goods. Which can afford to have these different vertical silo's for the coming time.

The domestic sector will remain screwed and you're better of to roll your own open source solution. Another solution would be to use a blockchain or one single database were the other appliances can see what is happening and roll their own interpretation of it.

Or we remain screwed and only put in an automatic light in toilet and done with IoT.
