I found this on Amazon. DSD TECH SH-B23A Bluetooth 2.0 to RS232 Serial Adapter with DB9 Converter. The pictures in the Amazon listing didn’t show jumpers. Some sites say you need to hold the switch while powering up others just change the jumpers ahead of time. I think it depends on what hardware DSDTECH actually ships you.

Software to set the baud rate can be downloaded from DSDTech-Global

Manual for the device.

Set the baud rate. For me I connected a serial adapter to the serial port on SH-B23A and set BAUD to 9600 and com port to 7 and selected the tab for HC-05 in the software. Set the jumpers to PC and powered up the SH-B23A then pushed the micro-button and the DSDTECH tool software would get an ok when I sent an AT command. There is going to be some trial and error here. When done move the jumpers back to Device for connection to a switch or whatever you are using. I have two of these and just set one at 115200 and the other is left at 9600 as those are the most common settings for me. Default connection in the software is 9600 mine below is set to 115200. The DSDTech website says to use HC06, mine worked with HC05 and failed with HC06.

Remember to switch the jumpers from “PC” back to “device” after changing baud rate.

If you don’t get an “OK” after pressing “test”, you’re not connected to your computer. And even though it looks like you are changing the device parameters in the software, you are not. Worse, You will still be able to “connect” or “pair” via blue tooth with another device, but the baud rate likely won’t be correct (because you never actually changed it) and it will be connected via blue-tooth, but it won’t work (ie will not transmit data).

I used Windows 10 for my setup, may not matter.

Connected to the USB port on the front of a Cisco 3850 works well for power.

I am going to cut some holes in the case so I can press the micro button and move the jumpers without taking out the screws. Just need to use tweezers and something like a paper clip to push that button. I ended up not using the top half of the case.

Instructable with setup information. Another version with slightly different setup steps.

Amazon picture is different than what I get when I order, but what I have works fine.

I have several of the 18650 Ultrafire batteries in different sizes from 2500 mAH to 4000 mAH. I left a couple of them sitting unused for six months and when I came back they had discharged completely and would not take a charge.

I found on Google that I could direct connect power from a USB port and get these to charge up enough that my regular charger was able to bring one set back to a usable level of charge.

The second set wouldn’t charge in anything I had so I ordered a new charger from Amazon in the hopes that it would be able to revive this pair of batteries. Lucky for me it did and they now test out over 3.7 volts with a multi meter.

These were the 4000 mAH Ultrafire battery and they seem to be working fine now. the second pair are 3000 mAH and they just didn’t want to charge in either of the two chargers that I have. The new charger doesn’t seem to have this problem and so far the batteries have not even heated up while on this charger.

Recent events have brought to light the decline of civilized society and entitlement of the entitled people. I speak of those parking in handicap spots without a permit and those parking along side a handicap van that is in a marked spot with the parking space next to it marked in blue paint to ensure there is room to load and unload the van occupants.

Usually those lines n the pavement are painted blue and accompanied by signs on posts to make clear for the more dense. You could contact the local police however by the time they arrive the offender will usually be long gone and it will have further inconvenienced the people trying to use these spots by having them wait around for longer periods of time then what would happen if they just left a note on the offending vehicle and left.

For these special people that insist on parking in these spots remedies have been suggested such as leaving a note, placing a sticker on the vehicle or just shooting the vehicle with a paint ball gun.

Maybe that sticker is to much, also keying the offenders car or shooting with a paintball gun have been determined to be to much as well. This is something that has irritated me for years as my father had one bad leg that limited his mobility. Its possible this made me more aware of the situation and the problems it can cause.

I prefer the turtle coloring page but you can’t always have one available when you need it.
