Nothing like an extra week of competition and some great competitors to provide motivation... Father's day was launch day for flight 2 and with one exception it was a success! A 36" nylon parachute from Apogee Rockets was just the ticket for a safe return to earth.
I started with a slight...
Introduction
My project was to make a device that tracks and analyzes skateboard tricks.
This would be important for training and activity logging. The device would be able to recognize tricks, and also analyze how much force and speed is being applied to monitor your progress.
I chose this...
I had mentioned in an earlier blog that I was using a couple of 74HC4067s to expand my data acquisition system to 32 input lines and 4 MAX7219s to display this data with the help of 32 7-segment LED displays . In this blog, I'll elaborate on the programming that went into making this happen...
This phase in the project seems to be progressing slowly - probably because the activity I find myself involved in is very "non-electronic". I ended up riding across town to a distributor's warehouse and found myself a cylinder of CO2.
It's a refillable canister of CO2 used in a table-top soda...
Even though Rob kept insisting we start documenting our work, I figured I had time and I'd do it in the end and what resulted was a very painful last-minute rush yesterday. Thankfully, there's a 1-week extension and I plan to update this blog on a daily basis, starting today.
My name is...
Introduction
My goal is to create a Fitness Wearable gathering data from the BMI160 IMU. From the data collected I'm going to filter it to get linear movement using the Fourier Transform then save the data in the microSD and finally use the PAN136B module to connect wirelessly to an Android app...
Introduction
My project is to build an impact sensor using the IMU of the max32630fthr. Basically I wanted to be able to attach the sensor to an object so it could measure the impact force when the object is moved and store the readings to an sd card.
The difficulty level for this project is...
Introduction
"MAXBOT" is a low cost Robotic Kit using MAX32630FTHR board has the main Controller Core and is mainly designed to initiate development of Low cost Robotic kit as alternate option to costlier Kits like LEGO Mindstorms NXT & EV3 to ensure avoiding cost as a barrier for...
Introduction
MAX32630FTHR is a really powerful board with quite a lot of onboard peripherals. Most noticeably are the built-in accelerometer and the dual-mode Bluetooth low energy chip which unlock the door to use this board as a VR controller without any additional components.
The most...
My entry for the #makewithmaxim contest is a data acquisition and telemetry payload for a model rocket, a base station and software to control the payload and analyze its data.
The project, although not entirely successful in its first flight was a lot of fun. Perhaps some aspects of it...
Introduction
Many people suffer with pelvic pain and pelvic floor dysfunction mainly caused by aging, surgical procedures and accidents. The pelvic floor muscles are a group of muscles that attach to the front, back and sides of the pelvic bone and sacrum. They are like a hammock or a sling...
Introduction
This project initially sought out to create a VR data glove using the MAX32630 mbed controller to collect inertial, position, and finger information postion information and send that information via bluetooth. The TI CC2564 bluetooth chipset required a bluetooth stack to operate...
Bill Gates once said, "It's fine to celebrate success but it is more important to heed the lessons of failure". Yesterday's launch wasn't the complete success I had hoped but was fun, we got some great data and learned a thing or two for subsequent launches.
The rocket flew well, up until...
Ready to fly. I removed the reed switch and now power is turned on by plugging in USB power briefly and turned off by via a shutdown command. I also added a little more structural support for the boards, re-soldered the GPS receiver to increase the amount of solder holding it in place and...
So I was excited to receive the email that I had won a maxim board and even better surprised when the maxim board itself came in with the hdk device, but sad to realize that as soon as summer came, I became more and more busy. I would still like to try to make my solution for deaf and deafening...
Just a quick update. I have some software now running. The basic system is operational on the MAX32630FTHR board communicating with all sensors and radio. SD-card logging is not yet implemented, nor is being able to mount the device as a remote USB storage device. It uses a number of mbed-os...
Introduction:
The term "Analog and Mixed Signal design verification" means verifying analog and mixed signal designs concurrently. Hence, the traditional verification flow e.g. stand alone analog verification or stand alone digital verification is not sufficient to verify Mixed Signal ICs in...
The rocket and electronics package are built.
The electronics package sits on a 3D-printed base which mounts at the base of the nosecone using two screws. A 16GB Micro-SD card is more-or-less permanently attached using double-sticky tape to hopefully prevent vibration or acceleration...
Recent Electronic circuit failures (un-repairable) have convinced me that 7 years is the useful life of most integrated circuits and circuit paths even when covered with solder mask. The culprit apparently is the Tin (Sn) element whisker growth in Tin-Lead solder. Tin whiskers will short out...
Introduction
The aim of the project is to detect early risk of forest fires and to inform the forestry department to do prevention before the risk became a disaster. The sensors will sense the flammable gas in the air, rain intensity, temperature and humidity of both soil and air, it will also...
