I'm not a hoarder, but I like to salvage scrap wherever I can. Having just moved into a new apartment, I've dealt with more than my fair share of IKEA packaging. The flat packs are great for random bits of foam and large expanses of clean cardboard....
Late last year I was looking for an adapter or something and stumbled across these PCIe switch cards that insert in a PCIe slot in a PC and fan out to multiple slots. I was already using 16x GPU cards in 1x slots with surprising success, and thought...
I started this writeup/log with a plan in my head, but not written down here in detail. It looks like it is time to take a step back and look at the whole picture...A quartz clock epoxy blob contains the following logic (more or less):We got an oscillator...
Before i get too far into this this is a NON ISOLATED 5v supply really only for driving a small micro . What this means is you can not connect PC, scopes or any other ground test gear without understanding where and how your earth ground interacts with...
Open question does anyone know how i would go about removing the noise the main switching fet is making.I have been reading this:http://www.ti.com/lit/an/slpa010/slpa010.pdfPage2 is basically what I am seeing.Also get the same ringing when the with the...
This would not fit inside my trackball.Chopped it, soldered it, hacked it.Dead bug style. I soldered the wires long through the holes to keep air space underneath.The black 20 gauge wires soldered on top work with the female jumpers. These are for backup...
Long Story:Well I took a look at the design size and shape I first posted for you all to see and realized that I don't want a smart car. (The width is 4ft. wide) After a week of driving the dually truck for my father in-law and his nice turbo diesel...
I really liked the original design but it was just too small. So I stretched it out and added some of the important components for scaling and dimensioning. Old Design:Front end was more of an Audi R8 style with a Nissan GTR tail.New Design:I decided to...
When working on a new project its always a good idea to plan ahead, its easier to build around parts you have then to find parts that will fit what you have built.This is a preliminary list of components for the mechanical aspect of the Medicycle and...
This is a preliminary list of components for the balancing and power electronics and where to find them.Arduino Unohttp://store.arduino.cc/index.php?main_page=index&cPath=11Arduino Megahttp://store.arduino.cc/index.php?main_page=index&cPath=11OSMC Motor...
For the past two days I have poured over ssd1325 datasheet and also figured out most of the schematics. I used the multimeter contuinity tester,a pair of custom made probes for tracing back the connections, a 5x magnification lens and a lot of patience....
Mechanical drawing of my EPD ePaper display GDE021A1 is shown below. Signals to the display are connected via a 24-pin flex flat cable. The pitch between pins is only 0.5mm. A suitable matching connector is MOLEX 52435-2471 FPC RCPT 24PIN 1ROW.On Thursday...
10/15 UPDATE: Good 3rd Gas Engine test! See bottom for details...Ok, so things are finally in a good state to start doing the second round of testing. As I did before, I'll be updating this project log as I go, instead of making multiple logs. I'm trying...
Well, I said I'd be able to fix the vehicle quickly and go back to testing right away. The weather did not cooperate. There was about 4 inches of standing water underneath Goliath on Saturday and it's still drying out. Unfortunately I'm out of time to...
