Q: Should I assemble with standard PVC solvent cement or just assemble dry? Seems like it would leak, but the instructions don't say anything.

Arrived safely, despite being very poorly packaged for what, in the end, is a fairly delicate piece of equipment. These relay boards are quite interesting. They use an 8051 core MCU on the main board as the master to control an ESP-01S wifi device. In other words, the WiFi co-processor has far more capability and performance than the host board. That said, they work well and since these are genuine LC Tech relay boards, have excellent support out there. After getting the board working with the ESP-01S standard AT firmware, I switched to a version of Tasmota using a blend of the instructions found here https://tasmota.github.io/docs/devices/LC-Technology-WiFi-Relay/. The board that I received used the Nuvoton MCU so used a combination of the rules for the older 4 STC-based relay board and newer two relay Nuvoton units. If you don't have the serial receive/send part in the rule set then the board will eventually work, but will take a long time to start up. Note that to work, the Tasmota firmware needs the board in the mode with the red light, not blue as you might expect. Once that is done, it will work flawlessly. All in all a good board. They have good isolation between the possibly mains voltages at the relay and are as compact as you could possibly hope for.

I bought this toy for my daughter who loves the Jimny, especially in this colour. It is beautifully detailed and even has live axles front and rear. As an RC vehicle, it is surprisingly fun to drive, particularly when camping.

Q: Does the Shunt have to be placed in the ground line, or can I place in the positive line instead? For a grounded vehicle, it is usually easier to tap into the positive. I can't see how it can make any difference electrically since the red/black shunt line should just be measuring a voltage across the shunt, no matter what the total potential is.

Surprisingly good. I have no idea how the little valve works, but it does, and holds a decent vacuum as long as needed. Great for storing 3D printing filaments.

Input is tolerant to 6V solar panel so works well for using solar charged remote ESP32 for example as long as the unit never goes flat.

Excellent little car, be aware that the motor pinion and main spur gear is exposed so avoid areas with sand and grit. Will make a good donor chassis for my Tesla Cybertruck build, once I make a custom 45mm longer chassis.

Good drop-in replacement for the stock plastic extruder that also works with direct-drive conversions. Easier to feed in filament than original.

Very easy kit to work with. Everything that you need to get the BL-Touch going on your Ender 3. Note that if you are building a custom version of Marlin 2.0 for the 8 bit control board that it is extremely hard to fit good ABL support in along with advanced movement such as Linear Advance. I have an SKR-Mini E3 on the way so I just did 3 point levelling for now. I did not try the standard firmware suggested in the instructions.

This pump really sucks, which since that is it's purpose, is just fine. Pulls a lot of air quickly, perfect for evacuating storage bags.

Good value with a wide range of drills. The hand-held drill is well machined and the chuck holds bits well. Micro PCB drills came in their own little hard plastic case.
