content: Hi all!In the last few months I've developed a FPGA dev board named Icepi Zero - it is an compact FPGA development board with a Raspberry Pi Zero form factor.This development board is powered by an powerful ECP5 25F with 256 Mbit of SDRAM, allowing serious designs to be made. It also has all the I/O boards a Pi Zero has: 1x Mini video output, 3x USB connectors, 1x uSD card slot, 5x LEDs and 2x Buttons. (But with an upgrade! The USB connectors are now USB-C!)Thus you can use this dev board to emulate old systems, to develop custom cores, or just to use it as a Pi Zero hat for hardware acceleration.This was originally meant to give out to my friends who wants to dive into FPGA development using Icestudio's GUI programming interface, but after getting a lot of emails asking to buy one decided I've put it up on Crowd SupplyFind out more information here!https://www.crowdsupply.com/icy-electronics/icepi-zeroThe project is also fully Open Sourcehttps://github.com/cheyao/icepi-zero.Added with the open source toolchain for the ECP5 means that you can have an entirely open source design flow.Any feedback would be appreciated!

content: You are absolutely right: it is always worth asking whether existing tools can achieve the same results, especially for professionals. From what I have found, while tools like LabVIEW, Tinkerforge, Phidgets can handle parts of the problem (e.g. logic visualization, hardware interaction, robotics control) none provide a fully tangible programming experience that combines mathematical problem-solving, algorithm visualization, and hardware control in a physical, hands-on way. A dedicated physical programming kit for professionals would be something new and could offer a different way to interact with computation.

New Open-Source ESP32 Robotics Kit for Modular, AI-Powered Projects - Page 1

content: Hi folks, I want to share with you a product that my team and I have been working on for the past years to help breaking into engineering, and specifically, robotics easier for everyone.We launched the first CYOBot last year as an open-source legged robot called CYOCrawler. It featured a WiFi-based coding interface (MicroPython and Blockly) but faced limitations like limited SRAM, causing memory errors with multiple peripherals, and basic ADC audio that didn’t support clear voice commands. The previous design also lacked modularity, making hardware extensions challenging.After selling roughly 100 units last year (I know for some folks this number is not that much, but we're still learning and iterating from feedback), we just recently launched CYOBot V2, addressing concerns and wishlists from customers and the open-source community. We’ve upgraded the development board to use ESP32-S3 with 8MB Flash and PSRAM, allowing it to handle larger libraries and multitask efficiently. The new I2S dual microphones and speaker with a dedicated audio codec enable clear audio for voice commands. Plus, the modular design now allows easy swapping between robot configurations or custom bases.We also developed a learning platform for the robot, so that you can play and practice skills in machine learning, control theory, IoT, kinematics, and embedded systems. This is particularly important for students that we have interacted with, as having a hardware platform does not necessarily mean that they know what to do with it. This platform will soon be integrated with an online IDE that can interface with the robot using a websocket, so that the users can read the challenge prompts, load the activity directly to the IDE and start solving/learning right away.See the new design in action on our campaign here:https://www.kickstarter.com/projects/cyobot/cyobot-a-transformable-quadruped-robot-for-innovation-and-fun?ref=6waexzOn the other hand, the schematics and source for the board are available on Hackaday:https://hackaday.io/project/199084-cyobot-v2-transformable-quadruped-robot. The project is OSHWA certified.Would love to hear your feedback on the campaign and the product! At the same time, we'd appreciate having you backing us. Thank you!

content: Hello all,I wanted to share our new IoT focused board. We are aiming to start a kickstarter campaign by the end of January.When we got a question of a client for a low volume NB-IoT based sensor with GPS possibilities we found out therewere no boards on the market which are CE/FCC certified. There was the PyCOM GPy but it is discontinue and thecompany was/is very unstable (went into administration).We therefore set out to create a board which combines an ESP32-S3 and a new generation LTE-M/NB-IoT modemwhich also has GPS capabilities. The board also has efficient DC-DC conversion on board and a MosFET switch 3.3Vout so you can disconnect peripherals to save that last bit of power when needed.To make the end application as cost effective as possible we have included the GPS pre-amp and filter on-board whichmeans you only need to connect a passive GPS antenna. For example Molex has some really nice stick-on antenna's whichgood reception.We have made a website for Walter:https://quickspot.io/If you are interested in the board and it's crowdfunding campaign it would be great if you register for the newsletter.Kind regards,Daan

content: Thanks for your interest and queries.For reliable communication, WiSer have few retransmits and acknowledgement mechanism. It doesn't cache or store any data. It is a true wireless replacement of USB-TTL converters available in market. You can expect the same behavior as in those converters.WiSer uses ESP-NOW which intern uses vendor specific action frames by IEEE802.11 specification. Internally it uses checksum for data integrity.There is no latency in data. Please check out this live demohttps://www.youtube.com/live/unGk0qNVlIE?si=vzhuWo-_K_Zyiz54&t=1964. We presented it in an interview with Alax on hackster.io. In the demo, we access the serial debug port of the Raspberry Pi, and you can observe the response to commands, just as you would expect from any USB-TTL converter. We have also demonstrated the wireless programming of an ESP32 Dev kit using WiSer at the highest baud rate, 921600.The default configuration involves pairing one WiSer-USB device with one WiSer-TTL device. Therefore, with the current setup, achieving communication with two TTL devices using a single USB port on your PC is not possible.However, if I understand correctly that you aim to communicate with two TTL devices using one USB port on your PC, this can be accomplished by pairing two WiSer-TTL devices with one WiSer-USB device. Some adjustments to the existing WiSer firmware would be needed to facilitate this configuration.

We shipped Twine 12 years ago and are still supporting it.Twine was the seed of a good idea that still doesn't exist. Arduino is like building your own car. Smart home devices are like leasing a compact sedan. A PLC is like a Mack truck. So we built Pickup, an environmental monitor/controller that works out of the box but has a modular architecture to fit your task.It's a flexible little outdoor computer for growing, monitoring air quality, DIY science, etc. Plug in sensor cartridges or build your own; output analog signals, HTTP and MQTT to integrate with your software; and ready to drop anywhere. Yes, we like to tinker, but not to solve the same rote connectivity, power and deployment issues every time. This takes care of those, so you can focus on solving the interesting problems of your particular task.Pickup has hit its goal on Kickstarter (our fourth!):https://www.kickstarter.com/projects/supermechanical/pickup-is-a-sensor-power-toolI know it's not for most EEs, but there's a lot of people who need something specific to their business without the industrial-strength controller's price.

content: https://www.crowdsupply.com/tikstation/pika-power-boardHey everyone, I wanted to share with you a new power supply solution that I've been using for my DIY electronics projects. It's called the Tikstation Power Board, and it's been a game-changer for me.One of the things I love about the Tikstation Power Board is its compact size. It's only 2.5 x 2.2 inches, so it's small enough to fit in the palm of your hand. This makes it perfect for taking with you on the go, or for using in tight spaces where a larger power supply would be unwieldy.Another great thing about the Tikstation Power Board is its versatility. It can be powered by a 9V battery, a DC power supply, or a USB port, so you have plenty of options for how to power your devices. It also has multiple output options, including a 5V USB port, a 3.3V power rail, and three sets of 3.3V/5V jumper pins, so you can easily power a variety of different devices.I also appreciate how easy the Tikstation Power Board is to use. It has an on/off switch and a power indicator LED, so you can easily control and monitor the power supply. It also has a built-in voltage regulator, which ensures that your devices receive a stable and consistent source of power, even if the input voltage fluctuates.Overall, I'm really impressed with the Tikstation Power Board and I would definitely recommend it to other makers and DIY electronics enthusiasts. It's a great tool to have in your arsenal, and it's really helped me to power my projects with ease and reliability.https://www.crowdsupply.com/tikstation/pika-power-board

The individuals who are running the project have been very well supported and are now shipping. The full history of their project should be accessible via their website. They have done a particularly good job of showing the progress of the project and in so doing, still have the support of their subscribers. I think there's a lesson in that for anyone contemplating something like this.Very interesting details about the production of the unit and the challenges associated with ramping up production numbers.https://blog.flipperzero.one/shipping-started/

Just plug in a USB cable, open Arduino IDE, and change the contents of the screen with few lines of code.The cost is $109 to $129 dollars.I've used it for a B/W photo frame and Weather Viewer (where I modified their example). They have plenty of examples.I like the way black and white photographs look on this device.Here is the website:https://inkplate.io/https://www.crowdsupply.com/soldered/inkplate-6plus

content: Group Gets paired my tCam-Mini Wifi thermal imaging camera board with the special  priced Lepton FS camera module and is running a campaign right now. Pricing is really reasonable. Great if you want to start playing with thermal imaging. I've also just released new firmware for tCam-Mini that improves performance and adds features (as well as a matching companion desktop application version).https://groupgets.com/campaigns/978-tcam-mini-with-lepton-fsFull disclosure: The Lepton FS is a Lepton 3.5 that didn't pass all their tests so can't be guaranteed to hold to all the specs. But it is cheap! It will show thermal gradients. Of course tCam-Mini can be bought with a Lepton 3.5 and with the new firmware installed also works with Lepton 3.0.

content: HelloI plan to do a big project in sometime next year (still in development), but I don't and won't have near enough money for it. Thus decided that crowd funding is the only way it can happen.However, I am from Jordan and we are not supported as creators in kickstarter, indiegogo, or crowdsupply (also, project is not open source for this one). Searched but couldn't find a way.So do you guys know a way it can happen?The product will be a video scaler device which is capable of outputting up to 4k60. It takes all analog video formats (cvbs, s-video, component ypbpr, rgb scart, and rgbhv vga) and hdmi input (up to 4k60) + dvi input (up to 1200p or so)... then scales or downscales them to any resolution from 240p up to 4k60. it has 2 independent digital outputs plus one analog video output.it is made for gaming application (especially retro gaming, similar to framemeister) but works for everything else.The price to make one product is about 500$ assuming 100 quantity, so selling it for 700$ is the minimum I can do. even at 700$, most people won't be willing to get it since there are cheaper devices which can do 1080p\1440p very well so no need for 4k for them.4k60 scalers only exist from Extron and they have quarter the features and triple the price at this moment. So I figured 700-800$ could attract people to get it.best regards

This allows for multi year battery life.Details on how it works:1) Every 10 minutes it wakes up to read temperature and humidity.2) Samples are written to a circular buffer on an NFC EEPROM.3) The buffer is base64 encoded and forms part of a URL.4) A web application (also open source) opens automatically when the cuplTag is tapped by a phone.5) The web app unwraps the circular buffer, extracts samples and plots these in a graph.No app needs to be installed on the phone to view temperature and humidity samples on the tag. Use of a web application means that data can be shared with others or viewed on a PC easily.If you like what you see, please support me on Crowd Supply! Any questions, I am happy to answer on here.
