Why I wanted to save all those parts kits from my EE lab classes. What parts kits am I talking about exactly? These, including the others I got from friends who didn’t want them:
You see, I had this ability to know I was going to need them in the future for some sort of awesome project. Well Joe has been trying to get a project done to gather some info and I finally just said send me the schematic and I’ll build it. Amazingly when I saw the schematic it all became obvious. I saw what was being done and how it worked and figured out values that I could actually achieve. Spent some time at Radio Shack tonight and picked up parts and now every thing is in a nice clean box.
At some point I may rebuilt it to use the extra connector that is available for power, currently it is using a 9V battery on the inside. Currently this device is already on battery number two. I missed a soldier bridge and didn’t ohm it before hooking it up. Once I cleaned the bridge I did a full functional test with my ohm meter and it worked exactly as intended.
Now you may be wondering what exactly this little box is for. I will give you a hint otherwise you’ll have to wait for the video. The first three terminal blocks will have current flowing through them. The silver BNC connector on the right is for telemetry. Remember that this box is supplying the current. I would give you a schematic but it would become obvious. Those who already know, don’t spill the beans. You might also consider who the customer is on this one for an idea of what we’re doing.
I will say off on the side I have 100ft of speaker wire and another 25 feet of coax cable. Now I just need to put some labels on it and we’ll be done.
I will say when the Radio Shack guy asked me what I was building, I made sure to pay first. The reception as it usually is though was, “Awesome, take video and send it to me.”
