Pic Development on Ubuntu
I am about to try PikLab with SDCC (Both available via Synaptic Package Manager) and an ICD2. To install the IDC2 I followed this tutorial. It’s supposed to be for the Pic Kit 2, but its just about the same for the ICD2. SDCC also requires GPUtils, so install that too.
One problem so far is [...]

Voltage Amplifiers Vs. Charge Amplifiers for Hydrophones
I have come to the conclusion that voltage amplifiers are better than charge amplifiers. Equations state that the gain should be the capacitance of the hydrophone divided by the capacitance of the integrating capacitor. When creating two circuits with (about) the same gain, the voltage amplifier always outperforms the charge amplifier.
This could be because of [...]
Phased array V0.1 Finished :D Doesnt Work :(
I have implemented a new microcontroller that has simultaneous sampling and a slightly higher sampling rate. I could then interpolate the data with pretty good results using a simple padding + band pass filtering technique. The higher the SNR the better it worked.
However, I have hit a great big wall. It all [...]
