So I'm putting the finishing touches on everything so I can post it all online for your consumption, the project is done though, so I'm calling this a win. I created a set of labels for PICxie:That should be 1:1 scale by the way, to give you an idea...
Or how one should never trust existing footprint libraries without double and triple checking everything!This morning I decided to finally test the Computer with all cards inserted and... no clock! Not only did I swapped X1 and X2 on the CPU board, which...
Using more 1"x1" aluminum extrusion, I made a frame for the y and z motion of the gantry. The y motion is similar to the x motion; a pair of linear rails with bearings will allow it to slide freely with the motion being controlled...
There were a few hiccups along the way that I thought I would share for the benefit of future hackers.Initial Design ProblemsOne of the first challenges was having eyes bigger than my PCB. This project is an entrant in the Square Inch Project so I was...
We attached everything to a plywood sheet, we attached the sheet to an old metal stand, we got all the help we needed from our awesome team members, students and interns.Panaflex poster was printed with a simple background and header, attached to the...
Imagine you're me: A broke grad student with dreams of turning his scanning microscopy hobby into something more. You scrimped and saved until you could afford old blu-ray players and a 12 dollar USB microscope, then sold plasma until you could upgrade...
Big things come in Tiny PackagesPICxie is a very tiny (1"x1"x1"!) but feature packed development kit for the Microchip PIC18F series of microcontrollers. Specifically the PIC18F26J50.Powerup your Projects with PICxie!PICxie is a stand-alone development...
Code for the big boat has been taking up most of my time, but in the mean time I've still been working on the sails for the little boat. The original sail design didn't work -- I couldn't get enough weight on to balance it against the overly long lever...
After digging through my collection of scrap building materials, I've revised my plan for mounting four concentrators in a box together down to three. It turns out that I've got at least twelve 2.4m (8') lengths of 4x2" pine, but only one length that's...
Built this out in Fusion360. Now I'm going to put the power supplies in the main LED cabinet. This will be hidden inside, will have three 120v fans, to move air over the power supplies. Will have panels to route the air across the power supplies....
Disclaimer: this is my first big 3d print project, and I was learning Freecad as I went. And Kicad. And 3d printing. The version of the custom software shown in the pictures isn't fit for general release but I do hope to release the next version of...
A few boxes arrived this week, so I got started on the thrust measurement frame this weekend. I watched a number of videos on safe CFRP working procedures (since I'm cutting simple shapes myself at home), including the one in the previous post. I spent...
