[Ultimate Robotics] has been working on designing and producing an extremely small ECG that can stream data real time. Typical electrocardiogram equipment is bulky: miniaturization doesn’t do much for a hospital where optimizations tend to lean towards, durability, longevity, and ease of use. Usually a bunch of leads are strung between a conductive pad and […]
Bobble-Bot uses the standard inverted pendulum problem to teach modern robotic control using a Raspberry Pi, RT-Linux, and ROS. We’re really impressed by the polish and design effort put into this project, and it’s no surprise that it’s a finalist in the 2019 Hackaday Prize. Bobble-Bot is a top heavy bot sitting on two BLDC […]
[Jakob Kilian] is working on a glove that he hopes will let the blind “see” their surroundings. One of the most fascinating examples of the human brain’s plasticity is in its ability to map one sense to another. Some people, for example, report being able to see sound, giving them a supernatural ability to distinguish […]
[Dan Kitchen] has a great solution for making servos easy to hack. Every hacker has a drawer full of servo’s somewhere. Just about every project that uses them starts off by measuring the spacing and designing some obscure bracket to meet that unique motor’s size. However, what if you could use common wood screws and […]
We’ve seen a lot of motor driver boards for robots and the odd electric skateboard. What we haven’t see a lot of is one big enough to drop into an electric vehicle. The Axiom motor controller was a winner of the bootstrap contest and is a Finalist in the 2019 Hackaday Prize. The driver aims […]
SmallKat is a cute little robot with a lot of capability designed around teaching and experimenting with dynamic robot control. It’s a shame we haven’t covered SmallKat yet, as it’s both a finalist in the 2019 Hackaday Prize and was one of the Bootstrap Winners this year. Many hobby robots move by repeating a pre-programmed […]
[BlueFlower] sends in this cool wine bottle engraver. It’s a simple machine that reminds us of the infamous EggBot. One axis can move in x and z while the other axis rotates the work piece. The EggBot works in spherical coordinates while this one lives in a cylindrical world. The base of the device appears […]
[flow] is a little disillusioned with commercial Data Acquisition Systems (DAQs) and channeled his frustration into his own, very cool, FPGA based solution. The project takes form as a back plane into which various cards can be slotted. The the interface is just a PCI-e connector. If you need analog input, simply insert the card […]
We all know how important bees are to our ecosystems and [Kris Winer]’s bee monitor provides a great way to monitor these amazing but delicate creature’s habitats, hopefully alerting us before a disaster strikes a vital hive. The board is based around LoRa sensor tile called Cicada but redesigned to make it smaller and cheaper. […]
[Jan] is solving a problem many of us have had, deeply discharging our project’s batteries and potentially damaging the cells. His board can handle batteries from 6 to 34 volts and supports both LiPo or Lion batteries. The board can be flexible about its cut-off voltage. It also has a feature we really like; the […]
