I Love Wire

Posted by jw0752 Top Member Aug 17, 2017
Yes I admit it, I confess, I Love Wire!     A while back Alpha Wire announced the release of a new wire called Thermo Thin Hook-up Wire. Here is their announcement on e14 in case you missed it.   https://www.element14.com/community/groups/alphawire/blog/2017/06/08/alpha-wire-releases-all-new-600v-thermothin-hook-up-wire   The announcement offered a free sample so I signed up. That was June 8th. Today two months later I received 2 FEDEX packages each containing 2 feet of ...
If you have followed the previous 3 posts about this project you know that we are at the point where the rubber meets the road. I have now put the interface circuits, that were previously on bread boards, on to an Arduino shield board. The shield will make all of the necessary connections to the Arduino. The connections from the interface board to the rest of the circuit are being assembled so that I will be able to easily disconnect and remove the interface board for modification or service if ...
The purpose of the Process Duration Timer (PDT) is to provide a means to set up an experiment and time a process, whether it is the discharging of a battery, the discharging of a capacitor or some other process that one does not want to sit around and watch. The PDT allows the experimenter to set up the experiment and walk away. The PDT watches the voltages and pushes the button on the stop watch the second that the process voltage crosses the target goal.   In the last three blogs we hav ...
     I will begin this blog by showing you how I have mounted the power supply into the project box that will be used for the Process Duration Timer. After a lot of searching in my transformer grave yard I found one that will allow the power supply to deliver 0 to 30 volts for the Target Clock Off Voltage. I have mounted a Recon R78C9.0-1 DC to DC converter to the power supply board. This will supply Vin to the Arduino as well as power the clock and the voltmeters for the Tes ...
