Designing the custom LCD
Log from Fluke 8060a Custom LCD
Dave at eevblog posted an excellent video series on designing custom LCDs, so I watched those a number of times. I also found another eevblog user who posted a great writeup of a replacement LCD he designed for his Tandy/Radio Shack TRS-80...

I added the Tindie logo
Log from Hackable Electronics Badge Alternate Logos
At the OHSummit, I was joined by Amber Cunningham, community manager of Tindie. While Hackaday and Tindie have the same overlords ruling over them, we can't really have Amber going around with a Hackaday logo on her badge, can we?...So I spent 15 minutes...

Rev1 Voltage Test
Log from Multimeter
I did another test with the rev1 prototype, this time only measuring voltage, and bringing it all the way to the maximum voltage of 60V. Again I am doing calibration and comparison to my Fluke 101 Multimeter. This has a problem as the Fluke 101 does...

Plasma Effect for TMS9918
Log from Game Boards for RC2014
Plascii Petsma by Cruzer/Camelot has one of the nicest looking plasma effects I've seen for the C64. Since he included the source code, I was able to port it to the Z80 and TMS9918. On top of the features in the original C64 version, I have...

Understanding how the computer works
Log from Apollo Guidance Computer
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...

ROM checksum code
Log from Re-UD-80 - a larger display for Epson PX-4 / PX-8
The 5.21E ROM works file with the current board, but the 7.11A ROM uses a different pin for the vertical sync signal. This can be fixed, but then the 5.21E ROM results in no display. Rather than fixing the hardware (with a jumper to be changed when the...

3. Fundamentals of Hexapod Robot
Log from Hexapod Modelling, Path Planning and Control
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....

Terminal-BASIC programmable calculator
Log from Terminal-BASIC
I think about Terminal-BASIC based programmable calculator, like MK-90 I am planning to use Arduino DUE, TFT screen schield and custom matrix keyboard of40-64 keys.Does anybody know, if this shield is compatible with arduino DUE?Actually, I'v just tried...

We Have Blinkenlights!
Log from 2:5 Scale KENBAK-1 Personal Computer Reproduction
With the wiring complete I wrote a small program in Python to test the lights, buttons, and switches on the front panel. To be clear this is NOT the KENBAK-2/5 emulator running a program (yet). As it turns out I did have to replace one of the LEDs...

side quest: temperature measurement
Log from automated gardening - reservoir infrastructure
I must confess I haven't spent much time looking at NTC curves before. My prior knowledge was that they are somewhat ill-defined and can only deliver reliable measurements when calibrated individually. source: https://support.belimo.us/Documentation/Standards-Compliance/957165601/What-is-the-difference-between-NTC-10K-Type-2-and-Type-3-sensors.htm...

Debugging
Log from 8 Bit TTA Interpreter
Debugging Need to get this project working. One problem is that the Nano does not have enough pins. So I have used a Meduino (a Mega2560 Pro Mini). Here is the schematic: Here is the PCB: The ports (P1 & P2) match the TTA8 bus. A problem with the Meduino...

Different SD card MBR formats
Log from OSI SD Card Operating System (OSISDOS)
I tried a couple of other cards and found that they have different MBR formats with no header. I noted this in a previous log. There's an offset at 0x01BE that points to the MBR. My theory is this is true for "bigger" cards. I think the reason I could...

Micro-coded controller deep-dive
Log from Custom circuit testing using Intel HEX files
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...
