"No worries - this is an important discussion and you're right, it's not at all easy to measure. We've spent a lot of time helping people (mostly b..." | Read more » almost 4 years ago

"Nice! Yes, light intensity and phi2 are linked at the hip, and changes in light intensity will produced changes in phi2 on the millisecond timesca..." | Read more » almost 4 years ago
"This is a really elegant project! How do you address the differences in light temperature (RGB) and intensity throughout the day? I wasn't sure i..." | Read more » about 4 years ago
"When our project was still a hand-populated circuit boards + ball of wires, I first found publiclab.org. I totally loved the spectral workbench. ..." | Read more » about 4 years ago

"Awesome! I think given our workload, ordering one may be easier... I'll just wait till I hear more on that front. Do you have a device yourself a..." | Read more » over 4 years ago
"Thanks! Yeah we've kept the data site hidden for a while because we're going to move it to the main site pretty soon. But you can find the curren..." | Read more » almost 5 years ago

"Still working on it. We made a revision to the detector which delayed us a bit. We're shooting for early march to ship. As a result, the beta si..." | Read more » over 5 years ago
