- Four weel drive with kink steering - Electric mowing height leveling - Two 85 watt mowing motors, each equipped with two very sharp blades, able to snap back on hard obstacles - On the fly interchangeable LiPo-battery with voltage monitoring, about...
12/13/15Doing feasibility study. Looking at Electric Imp modules, but open to anything. Data plotting will be key. I also like the idea of adding in statistical control limits which will flag shifts and aberrations of signal performance. Likely there...
We are developing an assistive exoskeleton for people with limb disorders. The idea is to develop a strap-on system for disabled users; which will help the user move around or help them to train the limbs. The exo will be controlled by measuring muscle...
147KV Brushless DC motor 2 5200 mAh 6S 20C batteriesTurnigy AE-80A Brushless ESC (We're waiting for a VESC on backorder)Custom transmitter/receiver: Arduino/Attiny & NRF2401IMAX B6 AC balance chargerReceiver-Side (on board) control logic in hope to increase...
A few weeks ago Simon Merret posted a question about how to control an electric wheelchair. The topic was closely related to a previous project I posted here about the path-planning of a similar vehicle. I decided to study the kinematics a bit further...
The plan is to build a fully automated system for my indoor and balcony garden. The basic hardware was already in place with some timers and other off the shell hardware, like 'click on click off' and a sensor set from GroThings. That worked, but; Unfortunately...
A project to graphically monitor your electric fence from the house using 433 Mhz HC-12 wireless modules. It is an original, unique approach to maintaining fence integrity This project avoids any need to deal with HV, as it uses a very cheap current...
At the beginning of the project, we have done a brainstorming with all the group to regroup our idea. All the group were agreeing to do a project about conversion of energy. The idea was to convert mechanical energy to electric energy. We were inspiring...
Here is the basic concept for the thermal circuit: The heat source feeds a heat pipe to a Peltier based thermo electric generator. There are two heatsinks: one on the Peltier and one in between the Peltier and the heat source to prevent extreme...
How does a Microphone Work ? A microphone is an acoustic to an electric transducer or sensor that detects sound signals and converts them into an electrical signal. In short, wind is not sound, will this project work ? My answer is...
Output Backlash: ~0.13 degree Gear Ratio: 7:1 (Can easily be modified to 3:1, 4:1, 5:1, 9:1, or 10:1). Motor: Herlea X8318S or Turnigy 9235 See the Github page for instructions, BoM, and CAD.
Part 1: Hot Foil Stamping This is what the end result of a stamp should look like And this is what an industrial machine looks like I started to look for cheap option on Etsy and Ebay and all I could find were some handheld device with a heat controller....
This probe was made for probing (what else) of electric field. Its input impedance should be about 1 MOhm in parallel with the gate of BF998 (about 1.5 pF). Its output impedance is 50 Ohms (tuned using both simulation and TDR). Just connect one SMA cable...
TODO: Add encoder for servo control. The idea was to drive all 6 motors in the same direction for torque but when approaching the set-point reverse a few motors and provide backdriving to prevent over correction. You can drive 3 forward and 3 backwards...
The boat hull is complete build of wood with a fiberglass paste to reinforce and smooth the bottom surface of the hull, this feature has required a lot of attention in terms of painting and water protection paint, there are 3 layer of pore stopper, 3...
