I decided that interface between ZIF-socket and host machine will be implemented with help of this antique ISA backplane manufactured in 1984 (I bought it for about $20 last month):I cut out it a little to remove part with pull-up resistors, because...
There are designs on the net for this, but they all seem based on a design with a fundamental error. They asynchronously reset the 8-bit counter when it reaches 207. This means it cycles through states 0 to 206, then very briefly becomes state...
TL;DRI'm proposing a minimalist Class AB power amp to drive an 8-Ohm speaker with AVR PCM audio as input. It uses two heatsinked TO-92 complementary BJTs and puts a quarter of a watt into an 8-Ohm load (the loudspeaker). Distortion is low for an...
Sunday, 13/08/2023, 10:55. I can't believe I'm saying this, but I think I will go back to the reversibly actuated artificial muscles. Yes, I know, I know, I just wasted so much time taking each single approach for their efficiency and now I'm throwing...
With integer division, comparison, subtraction already implemented, it was possible to squeeze in integer square root as the algorithm can reuse these operations. Note: all values in TOS are treated as positive (unsigned) integers, so it will never generate...
ESP8266 ESPboy CHIP8/SCHIP emulator packed with 90 games About chip8/schip: https://en.wikipedia.org/wiki/CHIP-8 Special thanks to: Igor (corax89) https://github.com/corax89DmitryL (Plague) https://github.com/PlagueRusJohn Earnest https://github.com/JohnEarnest/Octo ...
MethodThe idea is simple, just build the SDK in normal Dual Core configuration, but pin all tasks to the first core. We then can run a task on the second core which should (in theory) run uninterrupted by everything.But: We can't be sure nothing is running...
The EVE chip has a number of built in fonts. You can access them directly using the "cmd_text" command. I've added a new basic command in addition to the PRINT command - "GDPRINT"You can specify the font (#16-31), cursor position and colour, plus a string...
Remapping the KeyboardGiven most of the work is done with the "basic shift logic" how hard could it be?The basic shift logic:Well much harder than expected, here is the schematic:Now many will recognise this as a PLA (Programmable Logic Array).Designing...
Time to fully disclose the operation of the CPU ! The complete schematics can be found in the files section, SQ1C1841.PDF. REGISTER B Let's start with the simplest part. Since the CPU has no ALU, the most important task of the CPU is moving data...
I recently revisited the peak detect issues after a long break working on other projects. I was still dissatisfied with the accuracy of the peak detect circuit. I spent an evening playing around with LTSpice trying various tweaks...
Sunday, 20/08/2023, 15:02 There is no way I wil be able to finish this project log in a single day or even a single week, so I will just post this here, so if someone wonders "is this project still being actively worked on?" then, they will know...
Code RebuildI rebuilt the code for a different staing point. Instead of: B(t)=(1-t)^2*B0+2*t*(1-t)*B1+t^2*B2I refacted the equation to: B(t)=(B0-2*B1+B2)*t^2+2*(B1-B0)*t+B0The error squared for each "t" is: e^2=((Bx0-2*Bx1+Bx2)*t^2+2*(Bx1-Bx0)*t+Bx0-Xi)^2 ...
OptimisationI have been considering what to do next with the software PLL. Do I go the simple low pass filter and move on or spend more time optimising. It is a question of time versus likely outcomes. I have a good result, is it worth trying to make...
In this chapter, the fundamental concepts of hexapod robots such as walking gaits, stability, kinematics and dynamics are covered which are essential to obtain a better understanding of the control architecture that is delivered in the next chapter....
