Thanks everyone for the replies. Yes it is a Ti-83 with a Vernier LabPro attachment. This is only the second time I have had it out of the box so I still know little about how to use it. Today I have two other projects I need to do while daylight is burning. First I have harvested two dozen beautiful cedar posts from our forest. In an attempt to get our ranch more sustainable I will be making more products from our main resource, trees. I have been using an old timey draw knife to debark the cedar posts. This is unheard of around here, most of the ranchers now use steel posts. Steel posts are imported to this part of the US and for all I know they all come from China. The heck with that. Back when the ranchers did use wooden posts here in the southwest unpeeled cedar posts were employed. Cedar is a great wood for posts as it has lasting qualities not found in other wood found locally. We have found that the wood borers like to get under the bark and begin to deteriorate the wood quickly, Thus cedar lasts about ten tears in the ground. Anyway, we have been peeling the posts which is tough because our cedar is quite bracnhy. I worked out a rig for holding the posts while I use the small chainsaw to smooth the sides. The drawknife then slips through the bark fairly easily.
The second part of my project today is tied nicely to the first, I worked out a trade with a local organic gardener in posts for garlic for planting. He has fantastic growth of garlic during the last five years and he lives up in the mountains just like us. Boy howdy, I guaranty you haven't tasted garlic this hot and spicy. So, we are totally inspired to expand our garden next Spring to include a large patch of garlic. Planting time for garlic is now, he says. He has invited me to come to his place this afternoon and learn. I will bring the posts which he needs to build a deer proof fence as a second line of defense from the deer, on the way back we will stop be the local purebred horse ranch where they give away manure which has no hay or weed seed because they have rubber mats in the stalls for the fancy horses. It is our plan to mix the manure with wood chips from our forest and begin a large scale compost pile for next Spring. Yep I am going to be a regular farmer not just a tree farmer! How scatterbrained is this? Sorry Keith. Just teasing. This evening I will break out the book for the TI-83 and see how to use it. In the kit there are several probes, the one I am interested i is a pH sensor p# PH-BTA. Now that I look at this manual it has about fifty sensors available, starting with a 3-axis Accelerometer...Radiation monitor... Magnetic field sensor... Light sensor.. O2 Gas sensor, pretty much a you name it, they got it. Sincerely, Brian Rodgers On 10/21/05, David Howard <[EMAIL PROTECTED]> wrote: > A pH meter using a Ti-83?
