# Summary of #hplusroadmap IRC Log (Feb 17, 2015)

* Research on long-term heat stress application (8h/day, 4 days/week for 10 weeks) showed significant muscle strength increases (~5.8%) and hypertrophy without exercise training, potentially through stimulation of ATP synthesis via increased UQCRB gene expression.

* A paper on Savitzky-Golay filtering was discussed, particularly its application in smoothing electroanalytical data while preserving important features like cusps at turning points in cyclic voltammetry.

* A new approach to SHA-256 ASICs using carry-reduced adders was shared, potentially improving cryptocurrency mining hardware efficiency.

* Discussion of 3D printing capabilities for metal objects, including print-to-cast methods, conductive ink, and industrial metal powder sintering processes.

* Neuromuscular electrical stimulation (NMES) research was shared, noting that low frequency burst modulated alternating current produces greater force than the commonly used "Russian current" technique.

* Open source vehicle projects were discussed, including efforts to create printable car designs and the challenges of keeping such designs truly open source.

* Various DIY/open hardware projects were shared, including MySensors (open source hardware for IoT/home automation) and castnow (a command-line Chromecast player).
