I wanted to try this cheap fucking tester on offer on Aliexpress.
I don’t have much to say, it works quite well, i tried to make some measurements of a couple of electrolytic capacitors and making the comparison between LCR-T7 and the PEAK ATLAS ESR+ (paid almost 15 times more) the measurement result it’s almost identical.
Surely the positive side of this small and fragile object that will surely stop to working one day to another :-D which allows you to measure/test a fairly vast category of components.
Example:
- Diodes
- Zener diodes
- Resistors
- Potentiometers
- Electrolytic/Tantalum Capacitors
- Ceramic/Polyester capacitors
- Inductors
- SCR
- Triacs
- Transistors (N-E-MOS,P-E-MOS,N-MOS,P-MOS,N-JFET,P-JFET,N-IGBT,P-IGBT)
- Transistors PNP,NPN
- Battery (max 4.5v)
It also has an infrared remote control decoder which i find absolutely useless.
The microcontroller used in the LCR-T7 is a clone of the ATMEL ATMEGA328, the Lucky Green LGT8F328P which is practically identical to the ATMEL but with additional capabilities such as higher speed and has a higher resolution for converting analog signals and having a digital-to-analog converter as well.
Below are the photos of the inside.

Finally a useful object that works very well and i have tried many.
This mini vacuum cleaner (4hapa) that uses a BRUSHLESS motor (be careful when choosing which model to buy) besides the “vacuum cleaner” mode it also has the “blower” mode and i assure you that it BLOWS and quite a lot (two selectable speeds).
So finally i can finally say goodbye to compressed air spray!!!
The package includes over 4 spare filters (washable), various adapters, the USB battery charger (5v to 9v) and a bag.
The only negative note; Yes! it makes some noise! i’ll get a reason.

Observing these two displays at first glance there are no big differences are noticed.
Wrong! the Display where you reads V2.0 (updated version of the previous one), also works perfectly if inserted very close to the PCB of a Switching Power Supply, the other one instead at Random resets and displaying 888 just move it 10 CM away from the Switching Power Supply PCB and it works perfectly.
I wanted to share this news because i’m not the only one with this bizarre problem.

A new version of the firmware for the Ultimate-64 (U64/U64E) / U2 / U2+ / U2+L by Gideon is released.
This release has again some significant changes for the firmware upgrade. Please read the manual before installing 3.10i.
Background:
If you would take some time to check the commit history of the repository at GitHub, you may find over 500 commits since the last released version, 3.10a. This is a lotttt more than it usually takes to release a next firmware version. The version is still 3.10, so there are not many functional changes. Yet, files have been touched, updated, or just made compatible with the new Ultimate-II+L hardware. It was more difficult than expected to get the Lattice FPGA to work correctly and keep compatibility with the existing hardware platforms.
On top of the new introduction of the Ultimate-II+L, there is still a need to support the “good old” 1541 Ultimate-II (or simply: U2). There have always been issues with the Microblaze processor and the compiler from Xilinx. Every version of the Xilinx compiler had different bugs that caused the Microblaze based firmware to be broken in one way or another.
Since the U2+L runs well on the Risc-V, it was decided to upgrade the CPU inside of the U2 and ditch the Microblaze forever. Unfortunately, the CPU that was chosen to run inside of the U2+L did not fit in the same space as the Microblaze clone, so I decided to write my own Risc-V compatible CPU. This is the CPU that will be used from now on in the 1541 Ultimate-II.
General Fixes:
- [Important] Fixed ExFAT filesystems with 128kB clusters (Fixes failing D64 mounts from some ExFAT thumbdrives)
- [Facebook Discussion] EasyFlash save function now saves all chip chunks to support incomplete CRT files
- [Issue-271] GEORAM at boot (MarkusC64)
- [Issue-279] Support for 2 MHz operation for any cartridge, including EasyFlash
- [Issue-246] Fixed: Virtual Printer crashes when file cannot be created.
- [Issue-234] Deleting last item in directory makes selection invisible
- [Issue-236] Confirmation modal asking a question only gives ‘OK’ instead of ‘Yes/No’.
- [Issue-R17] Added mapping of ESC key to RUN/STOP.
- [Facebook Request] Added: Leave menu on mount (can be selected per drive)
- [Facebook Bug Report]: Fixed starting Kingsoft Business Basic cartridge
- [Facebook Bug Report]: Allow Maverick (and others?) to write wrong sector headers on MFM tracks.
- [Facebook Bug Report]: Unable to select GeoRAM. Is now a mode of the RAM Expansion Unit.
- [Facebook Bug Report]: Fixed color palette not loaded at boot (U64 only).
- [Facebook Bug Report]: Fixed USB sticks not recognized
- [Messenger Report]: Improvements to palette file read. Rejects faulty files. Fixes hang-up
- [Messenger Report]: Fixes ‘Create DNP’ when run from Telnet. Turned out to be a stack overflow.
- [Email Discussion]: Adds EEPROM segment to GMOD2 when it is missing in the CRT file
U64 core fixes:
- Multicolor graphics side border bug (core version V1.41 => V1.42)
Modem fixes:
- ACIA NMI pulse extension to extend over bad line. This allows the 6502 to see it always.
- Performance optimization ACIA / Modem
- Allow spaces after ATDT command.
- Minor fixes in the modem emulation layer from Scott Hutter (xlar54)
Cartridge Support:
- [Issue-314] Added support for Blackbox V9.
- Additional C128 cartridge variant that allows banking and offers some RAM (U2/U2+/U2+L only).
Additions:
- Firmware target added: Ultimate-II+L; the Lattice version!
- System Information page (F4) now shows elaborate version info.
- GEOS support functions from MarkusC64
