TC66C Reverse Engineering

The TC66C Reverse engineering the TC66C USB-C Meter This is an interesting little USB-C meter, which I quite like. It has a very similar feel and operation to the meter I modified previously (TC64). This meter does support bi-directional measurement, so no modifiations were required to be able to use the meter at the device end of the cable. This unit will also act as a trigger unit which is really handy for devices that lack USB-PD functionality (Looking at you TS80, grumble, grumble)....

MDP-XP 90W extendable portable lab supply

The MDP-XP combo MDP by Miniware This is an interesting idea, taking the conventional power supply system and giving it the “Miniware treatment”, which I like to think of as, a nice aluminium housing and a jump in portability. I have reviewed a few Miniware designs recently, and generally I have found all of their products to be a really nice premium feel and quality. Probably the lowest quality (and cheapest unit) is the TS100, which has become rather well known as a portable soldering iron....

DS213 Mini oscilloscope review

The DS213 DS213 15MHz 4 Channel Scope The DS213 is a very small handheld scope from Miniware. Its marketed as capable of up to 15MHz on two of the channels, and 1MHz on the other channels. However, at 15MHz input, it is starting to round off and struggle with the signals fairly badly. At 8MHz (somewhat common for SPI), the SPI signals are easily understandable, and I generally use the two high speed signals for CLK and the signal I care most about from MISO and MOSI....

TS80 QC3.0/QC2.0 cousin to the TS100

The TS80 TS80 by Miniware The TS80 is an interesting spinoff from the TS100. Origionally called the TS200, it was intended to fill the market gap for an even more portable solution for soldering in the field. The soldering iron is designed to be powered using QC power banks at either 9V or 12V. The markings on the unit state 9V 2A (~18W). Which is a really low wattage for a typical soldering iron....

Reversing the current detection of a USB tester

RUIDENG TC64 The RUIDENG TC64 is a very low cost (<$15) USB-C inline power meter. It’s small with a very nice colour OLED screen. It tries to automatically detect if the USB lines are running in a few modes (QC, DCP etc). This unit is very handy for measuring the power consumption of USB-C devices, and it is moderately accurate (Good enough anyway for the price). It’s over on BangGood over here...

SPI Flash IC Notes

SPI Flash ics SPI Flash chips are a fantastic way to store a medium amount of information for a microcontroller when you dont wish to impliment a whole filesystem layer. This is great for when you do not wish to use a large ram footprint (no large buffer needed!). They can provide relatively high density storage for a low cost, and enable high speed data storage. This page will be updated in future, as my code progresses....
