# Summary of #hplusroadmap IRC Log (November 14, 2013)

* A discussion about safety concerns in DIY biopotential measurement circuits (like EEG/ECG/EMG) highlighted the importance of following medical standards such as EC11, EC13, and 60601, which require single-point failure protection and ESD protection to prevent potentially dangerous currents.

* Participants debated the safety requirements for transcranial direct current stimulation (tDCS) devices, noting that many DIY designs lack proper safety features like ESD protection, transient protection, current limiters, and galvanically non-coupled power supplies.

* A user shared information about ligand binding assays with a helpful visual explanation link (http://www.htrf.com/sites/default/files/htrf/products/ligand-binding-assay-description.gif).

* A business idea was discussed for customizable inflatable "moon bounce" structures that would allow children to design them using 3D modeling software before playing in them, with cost estimates ranging from $600-$2000.

* A paper was shared via paperbot about a Nature article (http://dx.doi.org/10.1038/nature.2013.12190), demonstrating the channel's focus on sharing scientific literature.

* A user inquired about research on cryopreserved cells reintegrating within tissues from the same individual, showing interest in cryonics and tissue preservation technologies.
