yup, that's where this project started, or something similar.

Hey, I built 6 sensors over the past weekend. I'll calibrate them this weekend.

Looking forward to seeing the results.

Do you know where to buy Hamamatsu G1118 in the USA ?

you have to call up the US Hamamatsu division. They're in Jersey but it's not practical dealing with them. That's why I used the publicly available photo diode instead.

Hey, I'll post 5 meters up in the 'For Sale' sometime in the afternoon tomorrow EST when I'm back from a meeting

I just got a quote for minimum quantity of Hamamatsu G1118 from Hamamatsu in Middlesex, NJ. Minimum quantity is 5 pieces for $18.80 a piece + shipping. They also have to order it from Japan which will take additional 2 to 8 weeks. I do not want to buy 5 pieces and I wanted to check if you want to buy 3 and I would take 2 for myself. If not I will just tell them to cancel the order as $100 for this is too much for me.

No, I don't need it anymore. They are a hassle. I think you need to be a business to buy them too from what I can remember.

The sale is up.

dzaninov · 02-11-2013, 09:21 PM

Ok.
They did not seem to care that I am not a company and did not ask to do a background check. The only problem for me is that the price is way to high unless somebody needs it too. At this price I would rather just buy the Apogee sensor.

Oh, I don't think we mentioned this but O2Surplus build in a FTDI connection into the meter. You can get a usb/ftdi adaptor and read the values from your computer, or read from your favorite microcontroller.

Actually- A USB/FTDI adapter is what's needed to make the connection. The adapters are widely available anywhere that Arduino parts/shields are sold.

**mistergreen** · 02-12-2013, 05:54 PM

right, oops, I got uart in the brain with another component.

Set the serial baud to 115200 to get the data through.

Hey gents,

When is the next batch on for sale?

Whenever I'm free. I still have ~14 more to build. After that, that's it for me.

14 more to go.... LOL. We've created a monster, and I'm sorry. I won't point a soldering iron in your direction again.... unless you ask me to! LOL

lol, it's actually pretty easy now. It should go pretty fast. By the way, the meter you build is quality stuff.
