# Summary of IRC Log from #hplusroadmap (March 28, 2015)

* A user shared information about Lymnaea stagnalis (pond snail) as a potential model organism for neuroscience research, noting it has big neurons and a well-defined 20k neuron central ring ganglia that is relatively easy to prepare.

* Discussion about cloud chamber construction techniques, with recommendations for using server power supplies capable of 50A output (~£17 on eBay) to power Peltier cooling elements, and the importance of using adequate cooling fans.

* A user ordered 360W worth of Peltier elements for a cloud chamber project, along with CPU coolers, temperature sensors and PWM controllers from DealExtreme.

* A link was shared to exploit-exercises.com, a resource for learning computer security concepts through practical exercises.

* Users discussed Arduino IDE support for the ESP8266 WiFi module, which was described as "exciting" development for IoT projects.

* A user shared a project for measuring specific gravity in fermentation using ultrasound at 2MHz with a 100MHz ADC and FPGA processing to avoid interference from yeast foam.

* Discussion about Python programming concepts, particularly regarding object mutability, in-place modifications, and merging dataframes with timestamp alignment.
