While commuting in tram from one end of Bratislava to another one, I noticed massive sparks on collector head of pantograph when tram crossed via crossroads. That could be handy for welding the tabs to 18650 cells, I thought, but quickly came to conclusion...
Okay; I'm doing it.I still plan on fixing design files for previous designs but I'm going to try and make a new PCB for this thing. I keep finding contradictory information though, based off of the square reader it would seem that a tape head transducer...
I'm starting to become really nervous about the breadboard-based nature of the project as it grows and becomes more complex. This was really brought home to me a few weeks ago when I had to transport the board to work where I was demoing it to some interested...
The goal of the Open Modular Electronics Bench is to provide a modular and easily extensible benchtop instrumentation system, in order to facilitate a community-driven ecosystem of instrument modules. Haphazard design choices will kill adoption of any...
After half a day of soldering, the board looks like this: Everything fits like a charm, and it really starts to look like a Jupiter ACE. So it's time to start testing, and carefully insert all chips. Step 1: Check what is + and - on the power connector....
20200219 - Tuesday From now on I'm going to refer to the NICs by their most obvious identifier for two reasons: It's shorterI'm probably returning the original, but would like to easily be able to refer to either. I'll refer to the original as PT. I'll...
In an effort to improve the finish on my cuts I picked up a Hozly 1/8" two fluted down cut bit from Amazon. They came in today so I made a few sample 30 mm boxes to test them out on from a piece of poplar I had on the machine. From left...
I should have my test board for the 2SK3018 transistors back next week, but in the meantime I've been thinking about other changes.In the interest of adding more I/O capabilities, I think I've settled on adding an I2C interface to the Q2. I2C is...
The handles came and I'm finally done! For now it is just resting on the baes of the drill, I will probably attach it more permanently just to make things more safe, but otherwise I have nothing left to do. Someone suggested removing all but...
One of the most rewarding moments of Aiie, for me, is turning it on. I flip the switch; the screen becomes filled with inverted @ symbols; it beeps; and then I see "Apple //e" across the top of the screen. It's just like my original; I...
I thought some who are following along may want to see the internals of one of the gears as the YouTube videos aren't the easiest format to do detail. BLUF, this gear failed to produce torque beyond the same torque that the first hypocycloidal gear produced,...
Power ConsiderationsBecause each LiPo cell has a nominal voltage of 3.7 volts, to achieve our 35 watts of power we would need to discharge at (35/3.7 = ~9.5 amps) continuously. During start up, against wind, or up a hill the required power will be much...
As I mentioned earlier, I don't have much experience in designing any mechanical devices that move, so I knew this part of the project would be the most difficult for me. With that in mind, I started here so I knew if this project would even be possible....
(update: add note to Structure:Alignment)Here's an attempt to describe some of what makes this extremely low cost sub-mini CNC mill work. Hopefully having it somewhere to refer to will simplify writing more about how to make one for yourself! Axes Looking...
Thursday, 18:32, 18/05/2023 Bruh, I posted this one earlier by accident, lol Well, I felt guilt because I feel I didn't try hard enough on the previous project log, so I decided to finally make a drawing so I can visualize the final...
