  1. Just got back from setting up my Ameristep Doghouse blind, putting down corn and setting up an LZ10, H55, W100 and S600 at a friends place. This is the back of a sub-division I have been hunting. Killed two there last year. I am always surprised how close the main deer trail is to the back of his house. Can't be over 25 or 30 yards!! Took a look at it today and it is being heavily used. My shooting window looks down this trail. I'll post pics as I get them. Had some big bucks on camera last year but never saw them when hunting. Maybe this year???? Will also be hunting on some Corps of Engineer's land on the river. Have to camp in the boat there. Good Luck everyone!! Bill
  2. Something new to me!!

    Battery Internal Leakage

    Your welcome. I sure have to be a lot smarter as far as managing my stash of NiMh batteries. Bill
  4. I've been doing capacity checks on all my batteries on an annual basis. After testing the IR (internal resistance) I discharge them to the OEM recommended discharge voltage then charge them in a charger that shows how many maH were put into the battery. This has worked very well for me but by accident I discovered I had a few batteries that had lost considerable capacity sitting in the closet for a few months. One or two were completely flat. I only discovered this because my XTAR VC4 chargers show the maH put into the battery and it took a lot longer to charge these cells back up. In the future I will first recharge all the batteries to see how many maH are put into them before I do the capacity test. Found this on this site. Good rule of thumb on when to replace batteries. Quote- NiMH and NiCd belong to rechargeable batteries that have the highest self-discharge; they need recharging before use when placed on a shelf for a few weeks. http://batteryuniversity.com/learn/archive/the_secrets_of_battery_runtime Self-discharge increases with age, cycling and elevated temperature. Discard a battery if the self-discharge reaches 30 percent in 24 hours. Chart for NiMh batteries: The energy loss is asymptotical, meaning that the self-discharge is highest right after charge and then tapers off. Nickel-based batteries lose 10 to 15 percent of their capacity in the first 24 hours after charge, then 10 to 15 percent per month. Figure 7 shows the typical loss of a nickel-based battery while in storage. Self-discharge as a function of time I now have a standard to measure my batteries against. No use installing batteries in a build if they will exhibit unacceptable self discharge while in the field. Bill

    Bad day for slaves

    I only buy Vivitar 2800 flashes now. Have had real good luck. Only had 1 or 2 arriving unworking but the seller had stated that. I bought those for the circuit boards. Over the years I have had to replace a few transistors after much use in the field. I do agree Ebay seems to be more of a crap shoot nowadays. Bill

    Panasonic LZ10 Pics

    LZ10 Build Vivitar 2800 Slave Flash with one of bigbassman's orginial flash boards. Bigfoot Trailmaster Control Board with Panasonic Programming (15 sec. delay for night pics so the flash will have time to recharge and 3 sec. shutter delay to give camera time to focus) Gary did it for me and it works great. Even with the delays the LZ10 takes blur free pics very quickly. The only way to go. Two C cells for external power The LZ8 and LZ10 fit in the Otterbox 3500 just right with no modifications needed to the box or the camera. http://www.batterystation.com/otter3500.htm Bill
  7. In December 2017 I fully charged and conditioned my stock of PowerEx Imedion 2400mah batteries before I went to Florida. Charged up some today after they have been setting in my closet and all are taking a little less than 560mah before they are full. That's about 560mah depletion just setting in the closet. Be sure to charge all your batteries before installing them in the cameras!! Bill

    Question for the Electronic gurus

    Looks like it is a transistor. http://www.weisd.com/Mobile/MobTop.php?PN=ST25A Bill
  10. Thinning out the hogs in our deer woods. My brother-in-law jumped them and they ran head on into me. Have to use shotgun since it is turkey season. Using 3 inch magnum number 2 lead shot. One shot was at about ten feet. Saw about 20 hogs total. Sure tearing up our deer woods. Bill

    I'll do it when I get home in March. In sunny and warm Florida right now. Bill
  12. Excellent reviews!! Looks like it does a really good job of measuring battery capacity. http://budgetlightforum.com/node/55720 http://budgetlightforum.com/node/55835 On Amazon: https://www.amazon.com/Universal-Zanflare-C4-Rechargeable-Batteries/dp/B07428G1G2/ref=sr_1_1?ie=UTF8&qid=1518204280&sr=8-1&keywords=zanflare+c4 Bill

    Software driven analyzer

    May be worth a try. I do a lot of small battery testing at home. Reluctant to deploy cameras when the batteries have an unknown capacity after long periods of use. Thanks for the update!! Bill
  14. May be more than some need but looks very useful for those who are looking for a software driven analyzer. http://www.candlepowerforums.com/vb/showthread.php?443753-Test-review-of-West-Mountain-Radio-CBA-HR-(Battery-analyzer) http://www.westmountainradio.com/cba.php?navcode=/adwords_CBA Bill
