Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

Excuse me while i do something dangerous
You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.
Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

Hi folks!
I have some kind of memory problem on Lenovo laptop. I was initially able to install windows after several tries since the laptop did freeze in middle of those attempts.
Eventually I discovered that it was related to moving the laptop.
Later on it even stopped booting unless I pressed around the memory slot. (no keyboard LEDs only power button responds)
If I remove the RAM I get the beeps that RAM is missing. Inserting the RAM there is silence and it will not boot most of the time. No picture.
I removed the board got one of those memory slot testers... -
Hi friends
I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board... -

I got this device yesterday and did some testing on some tabbing and some incandescent light bulbs and it seems to work very well from what I can tell but how do I know how accurate the m-ohms section is what can I use to verify it accurately I also tested some li-ion battery cells and this seems to be fairly accurate because I have another tester and they seem to agree with each other
I also checked some capacitors with it that were brand new and seem to show about what I expected to see with my blue capacitor tester so I think it... -
Hi everyone! Been a while!
So I have a CM MWE 750 Bronze - V2 PSU powering the following:
Ryzen 5 3400G
Gigabyte B450 Auorus Motherboard
32GB DDR4-3600 (2x16)
ASUS TUF 1660 TI 6GB DDR6
1TB NVME
This was purchased by a friend about 3 years ago for her kid and now it showing signs of instability. The PC had this problem of the screen becoming garbled after it was booted up and idling in Windows. It also sometimes gets a BSOD. So I did some stress test by starting with Prime 95 and noticed that the torture test just fails and stops immediately.... -
When I first turned this battery testing machine the fan for the switching power supply was a little bit noisy but once I recapped the switching power supply board it quiet down considerably then I put a temperature controlled fan that does the mosfets control board was really noisy but now that it is cooled with temperature controlled fan that sensor was moved from the fan to the heat sink so now that the fan is controlled this way the fan runs according to the temperature of the heat sink
This switching power supply was really fun to recap the quality of the board was very good...
