I already have the basic skeleton of my computer ready, so it's starting to take shape. On the top floor is the backplane with the cards and on the bottom is the ATX power supply and HDD.
Abandoning the mess that was V1, I made a fresh start and designed easel frame 2.0. The basic shapes were dictated by:Full-sized ATX power supply on the bottom.Handle on the topTriangular easel frame to connect them, providing a means to support the...
NOTE: This post contains sponsored content. I finished rev 1 of a 5 slot backplane and sent it to PCBWay who were kind enough to send me some free boards to try out in exchange for a review of the service. Check out the end of this post for...
I did some tests of the 555 timer based temp feedback. The resolution at operating temperature was poor ~7 degrees. The resolution at room temperature was a lot worse ~30 degrees. The refresh rate was also poor. Seems the sensor chip was outputting at...
The enclosure is now completed: I added the connectors for the spindle, motors and power supply in the back and wired everything inside, including the ATX fan. Here's few pictures
LM1085 is too hot. I was trying with voltaje divider, OPAMP voltaje regulator, LM317, LM1085... Next I will going to get 3.3v with a step down converter but before I'm going to quit the LM1085 and get's the 3.3v from ATX power source directly.Also I...
Experience showed it was better to raise it all the way than lower it all the way to free up space. The original idea 20 years ago was to mount it on chains from the ceiling. The standing desk is about as close as it's ever going to get. ...
Summary1) The new driver board works2) An ATX supply makes a good DC supply for the driver3) An ATX SMPS transformer can drive an ultrasonic transducer4) I've ordered parts from DigiKey5) My ears hurt, and I don't know why...ATX supply makes a good DC...
For a looooong time I have only been able to find absurdly expensive programmers, none at a reasonable price. It SUCKED. Some on ebay were even 1000+ dollars! Ridiculous! Finally I found one for 42$ on ebay here. It came in the mail today and I finally...
With the waterfall part of the project working reasonably well, I’ve moved on to the electronics side of the project, beginning with control of the WS2812B LEDs.To power the LEDs, I found it convenient and cheap to use an ATX power supply. At full power,...
The very first proof of concept worked, and then some! I managed to cut some foam board with a makeshift foam cutter (Add one part ATX Power Supply, one part Nichrome Wire, one part wood, and a sprinkle of various metal hardware), and fit two 40mm EDFs...
A family photo of all the parts that went in. However, the heatsink was removed when it became apparent that i would have space constraints. The capacitors were switched out as well. Not shown is a USB hub I burnt out a while back that I used for the...
My old boards were an incredible step forward, but they had limited functionality, were not built with power/input/simplicity in mind, sometimes were unreliable, and were starting to die.The new boards have proper ground planes plus some cool new features...
Well, my 3D printer's hotend went belly up, so, I guess I'm going with my first design, the 8 slot case. The replacement hotels won't be here for a couple weeks and so, I can't do the top half of the modular case. The STLs are good though.I ran some...
No PC related build is complete without careful cable routing. I 3D printed some simple cable management loops which clip into a base plate attached to the side with some transparent double sided tapeAfter some careful research it turns out if you're...
