  • EC Sensor
  • Log     from UltraTower
  • EC is the abbreviation for Electro Conductivity. It is used to determine the nutrient concentration of the solution. This factor is essential to optimize the soilless culture. Indeed, the nutrient concentration will not be the same for a seeding as for...

  • Building an EC sensor.
  • Log     from Autodro
  • The end goal for the Autodro is a complete monitoring system for under $10. This means that cheaper, simpler, less accurate sensors are needed. I've started with a simple EC sensor, and am hoping to design something around $1.So far, I've created a sensor...

  • EC firmware dumped
  • Log     from Reverse engineering Toshiba R100 BIOS
  • After another long hiatus, I've come back to this project. Let's break this thing!I've etched a new board that lets me access important pins (serial TX, RX, CLK, BUSY ; RST and power lines) without having to fiddle with the previous hacky breakout board.I've...

  • Improvement of the EC sensor
  • Log     from UltraTower
  • It is better to read the EC sensor log before reading this one. I wanted to test the stability and accuracy of the EC sensor! So I replaced the EC probe with a fixed resistor (to mimic the resistance of a solution).   The EC probe was replaced...

  • Day 8a: convoluted ALU design
  • Log     from Detritus, the 8-bit ... computer?
  • Having picked a crazy overkill instruction set, it's easy to see how those functions map out in an ALU. 2 registers; an adder; and four logic functions. I spent some time over the weekend thinking about how this maps out to a final design, and in particular...

  • Orchestra 80/85 Support
  • Log     from TRS-80 Model 1 on a PIC32
  • The PWM has been in-place for quite some time (and is used for the 'cassette sound' feature that many games use), but I had never gotten around to implementing the Orchestra 80 support, even though it should be simple.  Part of the reason was that...

  • Soldering perfboard
  • Log     from Earth Lander 84
  • I took a perfboard and soldered up power and the data/address busses of the MCU, SRAM, NVRAM and the address bus latch.I did't really care about the exact order of the bits when wiring them up, I just went for the easiest layout. I'm not really sure...

  • [T] A3 Contact Image Sensor
  • Log     from Tetent UMPC [gd0149]
  • It's almost certain at this point that Leti will be over 300mm long, so only having a scanner that can do 210mm seems like a bit of a missed opportunity. Unlike A4, a handheld A3 document scanner basically doesn't exist. There are A3 all-in-one printers...
