# Key Points from IRC Log (September 23, 2014)

• A neuroscience-related image was shared by user archels showing what appears to be from DiPino's work in Frontiers in Systems Neuroscience 2014, potentially related to neural interfaces or brain mapping.

• An open-source syringe pump design was discussed, with links to a Michigan Tech news article about how researchers can now print their own syringe pumps, making science cheaper and faster, along with a link to the NIH 3D Print Exchange repository.

• A paper on neural array technology was shared, discussing electrode densities of around 4.5 electrode sites per mm², which generated interest among participants working on neural interfaces.

• A "Lost PLA" casting technique was mentioned with a link to a wiki page (fosscar.faikvm.com), likely referring to a method for creating metal parts using 3D printed PLA patterns.

• Microsoft's "Sharks Cove" development board was mentioned, which can be used to develop hardware and drivers for Windows and Android systems.

• A discussion about Bitcoin occurred, noting that BitPay and PayPal had formed a payment partnership, and that a mining company called "megabigpower" had begun offering mining franchises.
