Reverse engineering - first steps
Log from Late 90s GPS time unit repair & 1024-week bug fix
At this point it was late November. The obvious thing to do, given the device was working, and just displaying (and outputting on the serial port) the incorrect time, was look at using it as an accurate 1-PPS source and connecting it to a Raspberry...

Building a weather station from the TinyMLCookbook
Details from Building a weather station from the TinyMLCookbook
For more interest, I decided to build my model on another platform instead of the one suggested by the author (he implemented the case using TensorFlow Lite). I opted for a free-to-use platform, Neuton TinyML, in order to compare metrics of the resultant...

Have you tried turning it off and on agian
Log from RC5 Madness
Or: getting the correct codes I can send codes to the device, and they are recognized there ✅ Next, I need to find out what code I need to send to make the receiver go to standby. And to wake it up again. A nice bonus might be volume control. I already...

Alula Electric Conversion
Details from Alula Electric Conversion
I bought an Alula a few years ago. It was everything that Dream Flight said it would be, but my old damaged elbow joints did not tolerate the process of throwing the Alula repeatedly. The Alula is a DLG (discus launched glider) from DreamFlight. I bought...

Z80 SIO Emulation (part 2)
Log from 3-Chip Z80 Design
SPoC Code Side The PSoC will need to poll the IO_Stat_Reg and wait until it sees IORQ* asserted along with either CPURD* or CPUWR*. It should then read the AdrLowIn status register. Using this information, the PSoC should then perform the IO operation. ...

Power Analyzer
Details from Power Analyzer
Working Principle The ATtiny814 controls the electronic dummy load with its internal digital to analog converter (DAC). All of its 5 internal reference voltages are being used in order to get the maximum accuracy and resolution of the DAC. The DAC is...

Power Supply Issues
Log from GPS Driven Clock
This clock has been operating just fine for the last 11 months until about a week ago. We had a power outage due to an electrical storm. When the power shut down, it oscillated on and off rapidly for about 30 seconds. Apparently, this fried the buck...

0-30V, 0-7A Adjustable Switching Power Supply
Details from 0-30V, 0-7A Adjustable Switching Power Supply
DC to DC buck converters is a famous topology in the electronic and a widely used circuit in electronic devices. A buck converter steps down the input voltage while it increases the output current. In this article/video, I have discussed a DC to DC buck...

no remote, no problem
Log from RC5 Madness
First I wanted to find out, If the power socket on the back would turn off, if the device was in standby. Unfortunately, I do not have a remote and no way to reach standby without it, just proper off and on. So I threw together a circuit and tried using...

DIY legendary op-amp Big Muff
Hacker page by teardownit
Welcome to my guitar effects workshop! Today, we will study the circuit and history of the pedal, which is copied and improved by dozens, if not hundreds of companies and masters. And, of course, we will build and listen to our own copy. Almost every...

Safety and IoT to plain-old heater
Details from Safety and IoT to plain-old heater
I don't have a RaspberryPi Zero. In the meanwhile I am prototyping with Arduino Nano.In most parts of Pakistan, winter is short. The intense cold, that requires the use of space heating only lasts for about 6 weeks. Most households do not have central...

Lattice-Boltzmann fluid flow in matlab
Details from Lattice-Boltzmann fluid flow in matlab
Lattice BoltzmannLattice Boltzmann methods can be used to simulate fluid flow on a grid of cells. The goal is to parallelize the LB calculation onto the FPGA, but there are a few steps to do first. First figure out the algorithm and tune it in matlab....

Coin Cell Discharge Tests
Log from Coin Cell Jump Starter
Early on I figured I'd need to test some CR2477 cells to see how much energy they could practically supply in a short time. I finally got around to building the tester and putting it to work (not to spoil the surprise, but things don't look great...

12/21/2017 - A suitable display is found, design of the PCB continues.
Log from Sinclair Scientific Calculator Emulator
A previous search revealed that there were LED modules that were 15mm wide and had 3 digits. We need 3 of those side to side to get the 9 digits a Sinclair Scientific needs. Previous implementations using two packs of 4 bubble LED modules needed...
