Let's get cracking, get the Carambola up and running. I like to connect to the serial terminal, the development board features a usb ftdi chip allowing me to use a terminal program like PuTTy to connect.Connecting to serial terminalFirst step: see that...
When the junction box is roughly where you want it, collect a relay, and place it in the bottom of the junction box.Using self-drilling dry-wall screws, drill through the hole in the heat sink of the relay, through the junction box, and into the wood. ...
If you can't safely wire 120VAC, please stop here. I bear no responsibility for any bodily injury, death, or loss of property as a result of mimicking this project.Wired 120VAC through the Solid State Relays, outlets, and switches shown in the schematic.Within...
1) Come up with a simple good idea.2) Add good ideas to it.3) Try to implement it.4) When it fails, start to strip down the design to try to get it to work.5) Strip it down more6) More...7) Rejoyce when something simple works8) Add a few simple things...
Go to your local Big Box hardware store (Home Depot, Lowes, Menards, Ace, …). Find a nice employee in the lumber section and ask for "Four cheap two-by-fours, and someone to cut them for you". Getting the boards cut in store saves you time,...
make or find a pretty box. over build it.a round box is cool, but a bit of a painmake your box hard to open unless you have neat toolsthis box is planned for being epoxy and screwed to a wall outside
Expose the ImageLay the transparency on top of the photo paper and set it outside under a sheet of glass or acrylic. Professionals would use a UV light box (some of you may already have one for making PCBs), but 20 minutes in the California sun works...
Now that the PSU is done, Arguably the most difficult part, the rest is pretty easy. There are two major components that need to be built now: The control circuit for the HV psu, and the Hand sensor.These are the last two critical custom...
In this step, how the Arduino shield stack gets assembled, and how to wire your wave shield will be discussed. If you remember the note from the top in step 1, You hopefully used stacking headers to build your wave shield. If you didn't,...
First, here is the block diagram:You'll note that there are two relays in this circuit. These are used to connect the HV output to the hand electrode, and turn on the 12V supply to the Amp and HV power supply. You can spider wire them in...
To get a good idea how we made the electrodes, you can read the project update entitled "The Hand Thingie". If you want to use the same sensing set up we used, this worked well. Any sort of Object that is fairly ergonomic and can have the...
Find a small wooden box with a lid that has a transparent panel in the lid. My box had a thin wooden panel so I had to carefully cut out one end to remove the panel. Remove all the hardware. Stain and finish the box. Cut a piece of plastic from a CD...
Test fit all the components in the box to find the best arrangement. Cut a piece of strip board 8 rows wide and up to about 25mm long that will fit flat on the floor of the box. The strip board will act as a bus to connect to the header. I placed the...
Bend the pins on the header at a right angle. Drill 8 holes 1/16-inch (1.6mm) diameter in a line spaced 0.1-inch (2.54mm) on centers. Pass the pins through the holes with the header on the underside of the box.
