As explained earlier, the coil design has an usually high resonance frequency. With traditional Si-MOSFETs it is very hard to build a efficient fullbridge at this frequency. This is mostly because of the high gate charge and switching losses of mosfets...
See Update BelowContext being more that of the puzzle of cases not one case "to rule them all," but I digress. The past week I've been going through a few catalogs to find an enclosure for D-DAQ's mainboard. Previously, the PCB's form factor was based...
This represents a complete OPCODE list with 14 Constants (int values) available and 10 Labels (byte values) available for creating subroutines. Constants were favored over Labels, but this is up for evaluation. NOP and HCF were both added to the official...
First up, the latest revision. Small changes from the last version including tightening up various current loops in the buck converter and moving the battery-side transient TVS diode to the anode side of the reverse-polarity protection diode to...
In the first log I investigated the methods of growing bacteria, and extracting ,then purifying their PHA granules into usable plastics! A major roadblock is the usage of toxic solvents in the extraction and/or purification process. This means...
A quick update, with some of the high-risk high-gain aspects of the project!CC3000 WiFi Module and ChipKit Library PortIt's great to get out of your comfort zone and learn new skills or expand your familiarity with different aspects of design. For...
So, I got a little distracted. I was thinking about the user interface for the receiver end of this project. I've always planned on using a 4-line LCD ( or VFD ) display to present water consumption data to the end user. But it occurred to me that once...
I just had to follow the leads and trust my intuition. I had noticed that the last digits of the gPEAC moduli had a strange behaviour but I only dared to dig the matter these last days and oh boy was it worth it. I had already noticed that maximal...
So that we have our pads/traces setup, the next question is how do we best connect our transistors ?For a refresher on transistors SparkFun has a pretty good tutorial, including amplifier applications, so here just the basics we need for this project.Also,...
Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....
YouTube How to update CircuitPython firmware This method is suitable for the BPI-PicoW-S3 board that already has tinyUF2 firmware. If the flash of the board is erased or the failure to enter the UF2 mode occurs, you need to refer to the method of burning...
In a world of tech fairy tales, there would be nothing wrong with telling the Spark Core story as yet-another Kickstarter miracle that surprised everyone, especially its founders, who were subsequently left with only one option - to go ahead and change...
Following our post on IoT platforms, Spark guys reached out and asked if we can do a full interview. Given the unique position Spak is currently in (post-successful Kickstarter, betting heavily on Open Hardware and Open Software...) - we were more...
It seems you can't mention the Raspberry Pi these days without someone bringing up the Odroid. Named after the combination of Open and Android, the current Odroid brand covers several boards – the U3, the UX3 with its 2 Ghz Samsung quad-core processor,...
