About a year ago: One morning a colleague notices that a particular Windows share used by every EE in the multi-national company now contains encrypted files and generic request for ransom. Highlight of the e-mail thread that followed: &quo

The same reason small companies exist at all- they are more nimble and don't require to operate at large enough scale to survive. IMO, it would be pretty mad to start a company today around general-purpose conversational AI or general

If I understand it right, it takes this robot ~ 90 minutes to fold 5 towels.

In my experience, pip inside virtualenv manages dependencies very well. Completely agree on type checking point though.

> shipping is free That's why you get them in 3 weeks as opposed to 2 ;> With free shipping from DirtyPCBs my boards arrive to Latvia in ~5 weeks since order, so you should consider yourself luckier than you currently do :)

DHL shipping is another 20-25USD + VAT on import makes it closer to 50. But very cheap, anyway. Drilling itself is not the problem- just buy a nice set of drills with larger diameter shank and a small vertical drilling machine (Proxxon make

I have experimented with various at-home PCB production techniques: engraving, toner transfer, UV litography. The main limitation for all of these is fine pitch parts (less than 0.5mm) and plated holes (vias and through holes). The fine pit

It looks like you still need Calibre GUI to add books- this is read-only interface. I was hoping that this could replace my Google Drive folder with various papers on interesting topics I'd like to read.

I thought that this was a recently added feature. Turns out it has been there since at least 2011 (based on a forum thread about it). Will have to try it!

Now that you're asking- I don't really have an answer what exactly remains powered on. I have seen reports of people achieving sub-10uA sleep currents, so my result could be improved by a factor of 2 (LDO I put on board has Iq of

And Espressif got their act together this time and are working on a good and open-source SDK (ESP-IDF). I just tried it out this week to make battery powered wireless temperature and humidity sensors. Sleep current for the whole system is n

Technology getting cheaper allows to apply this technology to problems where it was not economically sustainable previously. IMO it's a good thing.

Hannover fair this year? Damn, I skipped this one, would have been great to chat with you. I am actually working on a prototype of something similar- Pi, camera, small touchscreen, distance sensor and small number of IOs. The two specific u

That's great. Are there any modules with support for camera and/or screen (HDMI/DSI) planned?

Have you tried SLC, pSLC or at least, industrial grade MLC cards? They are more expensive, but might be worth it in such applications. See this whitepaper on why: https://www.cactus-tech.com/files/cactus-tech.com/d

It's hard to tell from pictures, but are do IO modules have pin-headers instead of wire terminals?

Having to run cmake before make is usually avoidable. If you aren't using globbing but are specifying source (and header files) explicitly, just running make will do the right thing. Just running make also checks if you have modified C

I'm wondering about two things: 1. Can laptops with, say NVidia 1070 or 1080 GPUs keep them cool at their stock frequencies for a few hours? My work laptop with non-U i7 (Thinkpad T440p) starts thermal throttling in just a few minutes

You can also take the Kinect 2 apart and modify it for using external power input and regular USB3 (Type B?) cable. I have done that and it works well, see: http://www.tatsch-it.de/kinect-2-usb-3-modification/

I have been following this project since it was published on hackaday.io. Congratulations to Oskar and the rest of the contributors for getting it to at least alpha production. Question: I could not find information on what kind of control

I've had the opportunity spend about a week debugging incorrect configuration of SDRAM by BSP team. At first I blamed third party library with no source code available. Then it occurred to me that my initial SDRAM tests were doing wor

I understand it might be a trade secret, but what LTE modem do you use on receiver side? I would like to use LTE more, but finding suitable modems for embedded uses has been a challenge.

Cool, kudos for taking a responsible approach!

I hope the next revision of MAVLink (one of the most common message serialization/transport protocols used for UAVs) will have built-in encryption. While systems can encrypt MAVLink messages in transit, I have not seen it actually done

The problem with projects like Kafka is that they are geared towards cluster scenarios on beefy machine and cannot be embedded in other projects and used as a message bus. An example for which Kafka is not a good fit: embedded system which

While I haven't used Erlang, I have used other systems with nice messaging systems (PX4 autopilot and ROS) so I will try: 1) Data is passed between threads/processes using a message bus (essentially, a queue). This means, no need

Thanks for the responses! I have a feeling that projects involving vision will become more common with the fall in camera and image processing so I'm interested to learn from other's experiences. > Slick! Do you use that to det

By expanding the training set you mean that a each new sample is added to next training set by default? Do you use artificial augmentation of the training set (random rotations, translations)? Somewhat related aside: I have also worked on a

Cool build! I'm really interested in the classification process: 1) What's the input image resolution? 2) How many classes you have? 3) How many samples per class did you need to achieve acceptable accuracy? 4) How long did the tr
