What is the COP of a heat pump operating against this temperature gradient?

Quoting from their linked website: > Our heat pump can generate up to 3 times as much heat as a resistor, using the same amount of electricity. Though it doesn't mention the temperature at which this is achieved, only that the range is from 160 to 550°C.

That 'up to 3 times' is a very generic sounding Carnot cycle number. It's about the upper limit for heat pump performance, so it's not a very meaningful number IMO.

Not quite a startup yet, more a partially implemented idea, but I'm making a set of "retro consoles" to fufill a lifelong dream of making proper second screen games, in the style of Four Swords for the Gamecube. I've been honestly disappointed in the existing implementations, so I figure it's time to do it myself. Lua for game coding, fpga based gpus, and proper hardware expansion options. And that's all for the handheld. It's still in prototype stage, but it's an idea I've been mulling over since the DS released.

is it cross domain solution?

It is. Supports file transfers (sftp push and pull), XML (basically file with schema validation, different filters on each side of the protocol break), and TCP and UDP steaming. We’re proud of how fast it is, among other things.

Sounds interesting. Do you have any formal verification tools in your tech stack?

p.s. are you hiring?

Loads of hardware startups, but the communities are not in the Bay, Seattle or NYC. Most of the activity is not being generated by Americans or in America. Lots are being started in India, Dubai and China. Even the ones based out of the US or Singapore spend most of their time in Shenzen. In the US, I routinely see robotics and Healthcare hardware startups in Boston or San Diego, pseudo attached to the local universi…

Another consideration is that a lot of hardware startups focus on industrial applications with customers that don't operate out of tech hubs. There are tons of small companies making hardware for oil & gas applications, but you'll mostly find them in areas where their customers are located (e.g. Texas, Alberta) and/or LCOL cities where you can find cheap real estate. This also applies to other industries like agricul…

Where do you find these companies? I imagine crunchbase isn’t the best spot

I run 2 small IoT startups. One is smart agriculture related, we do ambient and soil moisture sensors https://pycno.co Second, (from the learnings of the first one) offers a smart IoT gateway (cellular, WiFi,LoRa, etc.) with modular cartridges (like SNES) for connecting sensors and actuators from any 3rd party vendor https://deeporbital.com

Seems very niche May I ask how you got in this venture?

Hardware is hard:founding hardware engineer, we were acquired 4 years ago by a corporate. We place WiFi sensors around your network that behave like typical clients. We report on user experience and show when there are issues in your network. WiFi technician in a box. The fact that it’s subscription based is what made us float. The initial capital outlay, supply chain, compliance and design work is so funding intensi…

we use such a thing called wyebot. it fits the description of that business model but afaict they all do. we went with to not be stuck with vendor proprietary systems eg aruba uxi.

it’s been horrible. feels like a hardware hobbyists product and not an actual solution. will stick with whatever the vendor offers next time.

a successful version of this product seems to me much more of a software product than a hardware product. the hardware is a couple of radios in a non offensive box. it’s nothing novel unless you go with SDR and even then i mean it’s been done. maybe poe power is a real challenge on that i’m not sure.

We are doing a military IoT products, for blue force tracking, supply chain control and low bandwidth datalink operations. Full stack - cases, pcb, firmwares, antennas, software and deployments. Can’t do show as we have only one customer now. As we are working in aggressive environment sometimes it is hard to keep cost in a reasonable range. Also finding a VC or fund interested in dual purpose or military hardware is…

How did you secure that first customer? Congrats

We make an e-commerce subscription that uses a smart scale to trigger re-orders at the perfect time. The timing is dynamic for each customer’s usage patterns. The scale lasts 1.5yrs per battery charge. Our customers cancel subscriptions at a way lower rate compared to typical subscriptions because their experience is way better. We bootstrapped to over 100 customers. We 3D printed the devices and hand soldered dev bo…

Brilliant idea

How did you convince the first customers to adopt this without a case study? I imagine selling a individual scale to each consumer is tough no?

#handWaveEmoji. Hello from Tapster Robotics, where we make small shoebox-sized robots for testing phones and other touchscreen devices (like payment terminals). Kind of an extension of my web and app testing work with Selenium and Appium.
