  • v2.1 boards are built
  • Log     from HC-SR04 I2C Octopus "octosonar"
  • The new boards are built and a very pretty blue they are.I mounted one up on the greenbot and it works as designed.I made up a test jig and an arduino sketch to wiggle all the pins and watch them from another PCF8574.I did run into some timing issues...

  • Due SPI problems
  • Log     from Memristor Simulator for a Neural Network
  • I spent way too much time working on the SPI interface on the Due today. Ultimately I found I was writing to the wrong address in the pot. However, I also found out that I can't seem to change the SPI clock frequency or mode using the Arduino library...

  • Animatronic E.T. Puppet
  • Instructions     from Animatronic E.T. Puppet
  • More details to come, including build out plans and implementationFind & paint milk crateEyeballs: sand eyeballs; paint irises, cover with XTC-3D epoxyBuild 3d model of head via photogrammetryPrint positive mold, then paper mache over moldFubarino Mini?...

  • Bleh...
  • Log     from Atmel SAMC breakout
  • (A couple of people have recently "liked" this project, so I thought I should post an update...)I'm ready to call the existing PCB design a failure.Aside from the non-presence of USB in the chip, the PCB was designed with the "sweet spot price" prototype...

  • Operating instructions
  • Instructions     from Braille Printer
  • To operate the printer open the arduino serial monitor. cells are drawn by punching dots anti clockwise from the top left position then moving the the start point of the next cell when complete"commands are entered in 3 character decimal."100" activates...

  • Control system now working
  • Log     from Manual SMT Pick and Place Machine
  • The machine can now be controlled by fingers!I revamped the breadboard circuit (3rd time) and got all 4 axis's working using an Arduino Mega 2560 and four L293E motor control chips. 8 of the analogue ports had to be used as digital ports, which was fine....

  • Connect the CO sensor
  • Log     from P.A.M.
  • Next session we will try to connect the CO sensor to an arduino to obtain our first values. How should we proceed? These are the schematics of the connections:https://www.dfrobot.com/wiki/index.php/Carbon_Monoxide_Gas_Sensor(MQ7)_(SKU:SEN0132) From the...

  • End of the sessions: where are we?
  • Log     from P.A.M.
  • Well, this is the end of our sessions, it came a litlle bit sooner than we expected.So where are we?We manage to make a device with two sensors: O3 and CO2. We just need to sold the battery to make it complete.Sensors values are taken thanks to a code...

  • Log 4 : 04/07/2017 - fusion 360 and troubles

  • Log     from M.A.B
  • getting further on fusion 360 ;)We are going to have one main frame with a second part that will slide in from the top (Y axis), this part will be a "L" that would cover the top too .For the way to "lock it" , well we are still thinking about it ......

  • ECU Software
  • Log     from Turbo Lexus IS200 (on the cheap!)
  • I have been working on the code for the piggy back ECU over the last few days. I am currently using an ardunio micro to simulate the factory ECU by creating 6 injector pulses at variable pulse lengths (engine load) and frequency (engine RPM).The injector...

  • Modification of Infrared Thermometer
  • Log     from DIY Thermal Camera
  • Luckily, the thermometer's circuit board has an unpopulated header that's ready for hacking. I wanted to keep my setup flexible so I used an old cable with the right number of wires and soldered a set of header pins onto the board. By making a hole in...

  • Programming the glider
  • Instructions     from OSUG: Open-Source Underwater Glider
  • Plug in the charging cable and connect it to the power adapter. Connect the tether cable to the Fathom-S topside board and connect the topside board to you computer. Download the latest demo code from either the glider’s GitHub repository or from the...

  • Design thus far
  • Log     from Modular Open-Source AV Receiver
  • A summary of my design thus far (work very much in progress) - 8 channels of digital audio (considering upgrade to 16 or more) - Backplane with PCI-express connectors (cheap connector with many pins, saves cost on module) - Daisy-chain modules to allow...
