Three years ago when I started this project, I thought I would upload all the parts to an online machine shop and hit submit. After > $20,000 quote I decided to go with additive manufacturing & investment casting instead -- and what a journey this has...
2020.3.20 // AC Servo buying for test update.As I was modeling, I was trying to figure out which motor would fit my robot, and I decided that AC servo motors were suitable, and I found a servo motor store in 'Aliexpress', a Chinese shopping mall that...
In this project, instead of using a standard embedded processor and programming it to execute 3 tasks at hand (parsing HEX character stream, generating HEX character stream, and writing character stream to video RAM driving VGA), I created 3 independent...
After the explorations with #YGREC-РЭС15-bis, I reached several limits and I decided to scale it down as much as possible. And this one will be implemented both with relays and VHDL, since the YGREC8 is a great replacement for Microchip's PICs....
Dyson V6 Setup and Running System Dyson handheld vacuum cleaners utilize high RPM brushless DC motors. Specifications indicate that some models can reach as high as 125000 RPM. I’ve disassembled DC56(V2), V6, and V10 models. Each has a brushless single-phase...
NEDONAND-6 is 8 multiplexers 2:1 with common control (straight select and inverted select):Board already ordered through OSHPark:Pins description:1.1) GND - ground 1.2) O0 - output of multiplexer 0 1.3) O1 - output of multiplexer 1 1.4) O2 - output of...
From OpenCores PDP-8 page: Features In this FPGA implementation, the PDP-8 CPU can be configured to emulate the instruction execution of a PDP-8 (Straight-8), PDP-8/S, PDP-8/S, PDP-8/I, PDP-8/L, PDP-8/E/F/M, PDP-8/A, HD-6100, or a HD-6120. The...
Original forum discussion from January 2017: https://www.brutman.com/forums/viewtopic.php?f=1&t=607 One of the slots (2x15 contacts) of IBM PCjr are intended to be occupied by modem, so we can re-use it, because that modem was useless anyway ( 300...
Now that i know how to access and decode the data lets try the Raspi GATTTOOL default BLE handler:Native to Debian and a lso to a bunch of linux distros or so i've heard of . First i reset the bluetooth of the raspi, just in case: sudo service bluetooth...
Fortunately most of the NASA documents are available. They can be found on-line at https://www.ibiblio.org/apollo/Documents/ The following documents are what I leaned heavily on in gaining an understanding of how this computer...
Right so it's been... checks notes... 36 hours since I wrote the log saying I don't know how to progress further. I've now essentially finished modelling the entire thing, and it should be smaller, better, faster and stronger than the previous...
As for the equation that will be used to determine whether a neurotransmitter triggers one of the intervals in a neuron, it will be as follows:where the numerator represents the sum of the specific neurotransmitter (t) from the neurons that are active...
On a lazy saturday evening I had nothing better in mind than hacking together a breakout board for my EA DOGL display. This type does need 9 caps and works with 3V3 only. So I had to add 5 level-shifters (10 resistors).Top view:Back view:Looks a bit...
When you're developing something that lives only inside of an emulator, there's a big chance that the code, which seems to work just fine in a debugger, will fail to work on real hardware. That's exactely why I wanted to hook up a logic analyzer and...
