Momentarily used a cardboard box for the laptop. It was a pain to set up, but worked. The only use was capturing MIDI in Finale, which was a painful program to use on a Mac. Stand bolted to piano: What lions used before. Too small...
Here is the electric Line Diagram of the Top Case, incl. 15 Switches to route the energy to the desired device(s). The 12V Input is connected with the 12V Output of the Bottom Case.Depending on the amount of activated devices (and power consumption)...
Here is a picture of one octave assembled. I'll cover more in detail each parts.Below is each extremity of the thing. You can see the Main Power line that is used to bring power to the Leds, and the Category 5 cable and outlets that are used to bring...
Thursday, 06/07/2023, 12:40.(I wrote this project log before copy-pasting it here) Anyway, back to DIY electric motors: I can't simply use two 10:1 reduction ratios (which would give 100:1 in total) simply because if I want to reach 30 rpm with...
Just had a major "EUREKA!" moment! CLEAN PORTABLE 120V/60HZ POWER ON DEMAND FROM TRASH GAS! One thing that's been bugging me as the deadline for the Hackaday Prize approaches is that the reactor part of the system is very simple to build and requires...
Monday, 10/07/2023, 08:52. Well, sh1t. Just now I remembered that there is a reaction between iron oxide (rust) and hydrogen gas: I can use this reaction to make pure iron powder in any grain size I want. In fact, there are tons of tutorials on how to...
Tuesday, 11/07/2023, 17:54. Well, I believe this will be my last project log on "theorics" of electric motors, and if you didn't notice, that's more or less "my last attempt", first I will list everything I need to do, then later I will make project...
I built my first ovens out of CMUs (cinder blocks). I already had a bunch of CMUs in my studio, and they had the advantage that they could be rearranged to change the shape of the oven, or taken apart and used in different projects when I was done....
Greetings, fellow hackers.Now I (really?) understand the philosophy of the jury. Push everyone to hack more. If you have success with your project, push for more and rise up. If you fail, push for more and rise up. Never give up. Never let yourself...
17/04/2023, Monday, 08:08 Well... Hello and good morning, I guess. Like I said in previous Project Logs, I calculated that I would need around 6000 watts electric motors (or 8 horsepower electric motors) in order to be able to lift...
from mcmaster-carr ($40)1) 1/2"x12" hardened stainless steel threaded rod with nuts for main propeller shaft. This allows me to clamp the prop, pulley and bearings to the shaft.2) 10mmx6" nitronic stainless rod for intermediate...
Dan Maloney 3:00 PM OK, welcome everyone, let's get started. I'm Dan, I'll be modding today along with Dusan as we welcome Nyeli Kratz to the Hack Chat. Today we're talking about biomedical engineering. Walter Lite 3:00 PM hi dan Dusan Petrovic 3:01...
I needed to reprint the bearing holders several times with slight variations in offset to align the shafts and get the right tension on the belts. This is much easier than reprinting the pulleys. The shafts need slight angles...
Saturday, 25/03/2023, 10:25Edit²:I kinda have a confession: I'm kinda procrastinating too much with this project, and I think I know why.You know how much I tell in these project logs that Mechs and Exosuits aren't viable and...
