Ever wished/wanted to use a Raspberry Pi as part of a LEGO Robotics Experiment, or need an alternative method to attach you BrickPI to a Robot you are building? Well, thanks to HansH and with the use of a 3d Printing Service you can have such a LEGO Compatible Raspberry Pi Base. The Raspberry Pi […]
BrickPi turns your Raspberry Pi into a LEGO® Robot. Your credit card sized computer enters the physical world. BickPi is a system that converts Raspberry Pi into a robot. The project is a board and case that connects LEGO® Mindstorms Sensors, motors, and parts to turn your credit card size computer into a robot. The […]
Finally my new Hongshun HAO301 arrived today after 7 long weeks of waiting. The Hongshun HAO301 is a USB Digital Storage Oscilloscope & Logic Analyzer. The HAO301 should make debugging LEGO Mindstorms and Raspberry Pi add-ons. Debugging will be a lot easier now as I will be able to visualize the Waveforms and Logic States […]
Dexter Industries are currently working a LEGO Mindstorms NXT Interface/ Shield for the Raspberry Pi. The Raspberry Pi is a credit-card sized computer that plugs into your HDTV. Add a mouse and a keyboard and you have a capable little PC which can be used for many of the things that your desktop PC does, […]
I've brought myself a 'Raspberry Pi' and I am planning to attached an external Hard-drive to it, in order for it to be used as a Stand-alone Media Server. I will use it to serve music to my Sony CMT-MX750Ni Mini Hi-Fi System. Unfortunately the Sony Hi-Fi can' access an external Hard-drive, just USB Thumb-drives. […]
Both the LEGO 7.4 Volt Rechargeable Batteries for Mindstorms NXT, are of Lithium-ion Polymer construction. Lithium-ion polymer batteries are light weight rechargeable batteries.
Do you own an NXT 'Intelligent Brick' with a flickering or non-working display? Steven Canvin, LEGO's Community Manager for LEGO MINDSTORMS, has asked us to pass on this message – Link to this post!
I've been experimenting with my new Mindsensor NXTCam. As most people are aware of the inherent issues associated with optical sensing, mainly due to changes in lighting level, can be very frustrating. In attempt to minimise this lighting issue, I decide to construct a stable light source for the NXTCam. To begin, I needed to […]
Still got that container on the bench with a pile of unsorted resistors left over from projects, or perhaps have purchased a mixed-lot of assorted resistors to begin with. Resistors have colour bands printed on them, rather than numeric values, which makes them more difficult to sort in you don't know the resistor colour-code of […]
I needed a LEGO Mindstorms NXT Cable Checker to allow me to Verify my NXT Connector Cables for connectivity or faults. A tester is particularly useful for when you are crimping your own cables. I picked up a cheap Network Cable checker of eBay for $2.50, and hacked it to suite NXT Cables. Unfortunately it […]
Below is Lego Mindstorms Compatible Laser Unit uses a 650nm 5mW (Red) laser module. I wanted to create a small compact Laser Unit that fitted in as small a footprint as possible. The Laser Module and other electronics fits easily into a standard LEGO '2×4 Brick', with a '2×3 plate' & Technics Connector attached to […]
I've been working on an NXT Keyboard for an Ordering System to use with my LEGO Mindstorms NXT Robot Crane with Ball Sorting Conveyor System, in conjunction with my NXT Line Following Dump Truck. The Keyboard uses 6x RCX type Touch switches connected to my RCX-TouchMux Sensor Multiplexer. Ordering System's Input Keyboard for My Ball […]
InThe Microsoft Xbox 360 Kinect sensor, is a horizontal bar connected to a small base with a motorized pivot, and is designed to be positioned lengthwise below the video display. The device features an “RGB camera, depth sensor and multi-array microphone running proprietary software”, which provides full-body 3D motion capture, facial recognition, and voice recognition […]
I brought this Hamy, 2.4Ghz Wireless 1/3 Sony CCD Rechargeable Camera to use with my Robots. It has a Sensitivity: of 0.5 Lux at F1.2, which makes it great for lowlight conditions. As can bee seen from the Video made with just the light coming through a doorway into a large room, its sensitivity is […]
I decided to modify a Lego Power Functions Battery Box and fit with an 11.1 Volt Li-Poly Rechargeable Battery Pack & use a Regulator I.C. to provide the regulated 9Volts required by Power Functions type Devices. The modification was easy, but time consuming to remove the excess plastic in order to get the Li-Poly Rechargeable […]
The Wii Nunchuk is designed to work together with the Wii Remote on the Wii console. Contoured to fit perfectly in your hand, the Nunchuk adds extra buttons, an analogue joystick, and additional motion-sensing control to expand the game play possibilities. It is also an I2C type device which makes interfacing to the Lego Mindstorms […]
This Lego Mindstorms NXT Appliance Controller allows you to turn on-and-off your Household mains powered equipment such as lights, radios, heaters, etc. All via your Robot. Using this Controller in conjunction with a Lego Temperature Sensor you can control your aquarium, and even as a incubator control to hatch out bird eggs. This […]
I have built a Lego Mindstorms NXT, 8 Input RCX Touch Sensor Multiplexer for use with the old style RCX Touch Sensors with full construction details Here in an Earlier Post. I finally got around to nutting out a Driver Library for use with John Hansen’s Lego Mindstorms NXT Programming Language NXC: Not-eXactly-C.
The NXT RCX_TS_Mux: NXT – 8 Input RCX Touch Sensor Multiplexer Unit with Sensors attached I have built a Lego Mindstorms NXT, 8 Input RCX Touch Sensor Multiplexer for use with the old style RCX Touch Sensors. I personally think these retro Touch Sensors are far, far easier to use in models due to their […]
