As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
This device is difficult to set up properly and takes some doing to master. Also it is not tolerant to reverse connection. I tried to charge a battery and blew out a diode rendering it inoperative. My suggestion is they should add a fuse to protect it. Also there are 2 pots for voltage and current limit. My suggestion is to replace this with DAC and turn it into a front panel setting instead of pots.
