Day2: more exploration ...
Log from Tsukuyomi
1. Datasheet.So thanks to the datasheet, we know now that Lunii chipset is based on a 16bit DSP core and I also found out that the 10 pts connector is belonging to ICE-Debug (very known in the arduino/avr world) and not for UART or SWD.Unfortunately...

A brief Theory on Hydroponics
Log from Teleimperium
Hydroponics is the act of growing plants without the use of soil. When growing plants in soil, water serves to make nutrients in the soil soluble and provides oxygenation for the plant's roots. In Hydroponics, however, the nutrients are instead made...

The strawberry died
Log from GrowInBox
It's been a long time since I last posted a project log and I've been trying to get myself to writing this one for a long time. I started writing it a long time but my computer crashed mid-log.Anyway. I left the strawberry resting on the windows sill...

Quick Update 03/10/22
Log from UltraTower
Currently, I am checking the new PCB and changing the code. As soon as it's ready I'll publish it. Corrections: There were2 errors on my PCB one on the pin of the DHT22 and one on the 5V pump which consumed too much power for the 2N7000. Everything...

20230216b -- "Files"
Log from ROM Disassembly - AlphaSmart Pro
The gist of this unit is that you type text into a discrete 'file' and then you can edit and later transfer to a separate computer via the keyboard emulation. While whizzing through the code doing other things, various strings caught my eye, such...

Building a model system
Log from Teleimperium
Since last post we've won a LightBlue Bean from http://punchthrough.com. It is a neat little Arduino compatible bluetooth dev board, hopefully we can integrate it into our project. The first step to this project is to get a simple hydroponics system...

When the Chips Hit the Fan
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
I received my AD8648 op amps from Digikey. For small orders weighing 13 oz or less (including packaging), you can't beat their price of their first class USPS shipping. I get my orders on the east cost within two or three days for only a few dollars....

We’ll be on Maker Faire Kyiv this weekend!
Log from uECG - small open source wireless ECG sensor
Quite symbolically, this Saturday, on March 2, Kyiv will host the first Maker Faire Kyiv in a long time! The last one was in 2018.Where, in addition to uECG and uMyo, we’ll present our first project in collaboration with TURFPTAx The device working...

We’ll be on Maker Faire Kyiv this weekend!
Log from uMyo - wearable EMG sensor with wet/dry electrodes
Quite symbolically, this Saturday, on March 2, Kyiv will host the first Maker Faire Kyiv in a long time! The last one was in 2018. Where, in addition to uECG and uMyo, we’ll present our first project in collaboration with TURFPTAx The device working...

20230221a -- File Deleting/Erasing
Log from ROM Disassembly - AlphaSmart Pro
Previously, while rummaging for scan codes, I was correlating known behaviour with key codes. One of those keys was the Clear File key (0x56). I forgot to post about that find, but it's still worthwhile to mention the file clearing operation...

Final PCB : Cost and Modularity
Log from UltraTower
This latest version of the board allows you to choose what you want to monitor in the tower. This board has been designed to be modular to suit your needs. We will look at each module one by one: Main module : This module is mandatory. It is the brain...

PCB V2
Log from UltraTower 2023
Like the previous PCB, you can choose the modules you want. This board has been designed to be modular to suit your needs. Update : - New alternating current circuit for disks and current control circuit (log)- Power supply voltage changeover from...

Nutrient Solution Maintenance and the Reservoir Revisited
Log from Hydroponic Garden Control with IUT
I have been working on the instrument assembly that would be partially submerged in the nutrient solution sump tank; both from a reservoir refill perspective as well as a nutrient replenishment standpoint (compensating for evaporation and rain-fill)....
