bigclivedotcom on Odysee

The trashiest electronic channel on YouTube. We test and use affordable electronic soldering equipment and tools to build, teardown, modify (and sometimes destroy) random electronic stuff. Many of the builds and projects featured here operate at full mains voltage and carry a high risk of shock and fire. As such they're really intended for either entertainment value or for those who do similar stuff. The videos are generally uncensored and may contain tasteless jokes, profanities and even blood and electric shocks when things go wrong. So just like a normal workshop really. So kick back, grab a beer and enjoy the ride.

  Professional haze machine circuit exploration

  Sep 16, 202628 min

  This video is an exploration of the circuitry used in many professional haze and fog machines used in the event industry. Notably the Haze Base, Unique Solutions machines. These machines share a common base control system, but differ in physical appearance. By understanding the circuitry it will help with fault diagnostics and identifying if a PCB needs replaced. The most common problems with these machines are pump failure, heater blockage and moisture issues on the control PCB. But relative to the heavy use equipment like this gets in the entertainment industry, they are very reliable units. Many of the problems can be attributed to user error and the rough life touring equipment has. These machines use a water and glycol based fluid (probably triethylene/propylene glycol) which is blown as bubbles of fluid through a heated pipe at around 200 to 250 degrees celsius. The sudden heat boils the water component, shattering the glycol into tiny airborne droplets. Mike Page has mentioned that the diodes in the thermocouple circuit are probably for an open-circuit test. If the test circuit is active and the thermocouple is intact then it will shunt the test current, but if it is open circuit the output from the amplifier will go very high. The unit I've just looked at did actually have a physically broken thermocouple, which flagged up as an E1 error. The vibratory air pump had detached from its mounting plate inside the unit and had probably rested on the thermocouple wiring, causing the bond to fatigue on the heater.

  Inside a cheap but impressive laser cube

  Sep 14, 202615 min

  These things are very widely available, which is a slight issue, as in the wrong hands they can pose a risk of permanent eye damage. This device should not be aimed at people's eyes and should NEVER be given to a kid as a toy. The circuitry is notable for the way the microcontroller is powered via its own regulator, and then turns on the rest of the circuitry by enabling another adjustable regulator set to 3.1V. That has two advantages. It greatly reduces standby current by disabling most of the circuitry in standby, and also allows the voltage to be chosen to suit the lasers with simple current regulation using a resistor. The rotating diffraction pattern disk runs far too fast in this unit, but that could maybe be slowed with the addition of a series resistor to the motor, noting that too high a value may cause the motor to fail to start rotating. I'm not sure if the voltage drop across the MOSFETs was due to PWM for laser current control or if they were not turning on fully and operating in their linear region. The green laser in this unit appears top be a DPSS module (Diode Pumped Solid State) that uses an infrared LED to stimulate a crystal to lase at a different infrared wavelength, and then that infrared laser passes through another crystal that frequency doubles it to visible green light. Unfortunately that means that a lot of invisible infrared laser energy comes out, and very few companies make any effort to filter that out. This is made especially dangerous by the critical nature of the frequency doubling crystal, which can be affected by temperature and other factors. It means that in situations like a cold environment it can look like the laser is very dim or barely glowing, and masks the fact that the full strength infrared laser component may still be present. Here's a link to the item on AliExpress (not a sponsor). This is an affiliate link, but that will not affect the price you pay. https://s.click.aliexpress.com/e/_c2uNstuL The item may not appear in some countries due to them proactively blocking lasers for safety reasons. The price also varies widely between sellers. Aim for less than £10.

  AliExpress unbagging joy - WLED controller, signage LEDs, timer module and more

  Sep 13, 202621 min

  Another gadget-blitz of technical goodies from AliExpress for us to explore. These videos are not sponsored by AliExpress. I buy all these items myself. Here are some links to the items. These are affiliate links, but that will not affect the price you pay. Keep in mind that these products may not meet your country's standards. Some listings may not work for some countries and some may just be sold out or disappear. When paying on AliExpress, let the transaction complete before leaving the purchase page as otherwise it may not go through. The WLED controllers are preloaded with the WLED firmware and have all the extra circuitry required, including onboard voltage regulation for the internal circuitry, level shifters for the data outputs and a MOSFET to turn the power to the LEDs off when not in use to reduce standby power. (Addressable LEDs have a small standby current that can soon add up.) The "warnings" that come with the controllers are just reminders to enable the output MOSFET. The WLED controller based on an ESP8266:- https://s.click.aliexpress.com/e/_c4ULJbJ7 You can also get a more powerful ESP32 version:- https://s.click.aliexpress.com/e/_c3v6oMjJ The 8X8 LED panel I used to test the units:- https://s.click.aliexpress.com/e/_c3HL5GMH The body sensing cosmic starfield toilet light:- https://s.click.aliexpress.com/e/_c4V5n9cz Miniature solid state relay available in AC and DC versions:- https://s.click.aliexpress.com/e/_c3z5hOXn When I said Osram I was thinking of Omron a prominent relay brand that gets cloned a lot. 1 minute to 8 hour timer module with or without case (case recommended):- https://s.click.aliexpress.com/e/_c4Mp5RPx There is a chart showing switch settings for the 16 time delay options. 12V addressable LED signage modules:- https://s.click.aliexpress.com/e/_c30uvhiZ Wireless Zigbee temperature and humidity sender:- https://s.click.aliexpress.com/e/_c3O0FXWZ Universal WiFi controlled switch for Tuya and other smart home systems:- https://s.click.aliexpress.com/e/_c4CnFDSZ The super-thin 12V 3mm LED strip:- https://s.click.aliexpress.com/e/_c38DFWVL I was hoping this might have a clear gel covering to see the LED and resistor arrangement.

  Total teardown of a common solenoid valve

  Sep 10, 202611 min

  I've actually made a video about this type of solenoid actuated valve before, but it's always good to have a revisit for those who may not have stumbled across the older video. This is a very common valve sold on the usual online marketplaces. It seems quite well made, but as always, you should use one from a prominent local supplier for any critical applications where failure could cause flooding or other adverse scenarios. But for experiments and prototyping, this valve will probably be perfectly acceptable. I like the way that the valve is entirely serviceable, so that if it fouled up inside, it would be viable to clean it out fully to restore normal operation. The entire valve assembly is so cheap that it's viable to just keep one in stock for quick replacement if needed. I got this one a while ago. I think it came from an eBay seller, but it is widely sold on AliExpress (not a sponsor). Here's a starter affiliate link to one:- https://s.click.aliexpress.com/e/_c3FKkTXZ Guide price £10 or less. It's available in various voltages. If you enjoy my videos, you can buy me coffee, cookies and gadgets by supporting the channel on Patreon.

  Russian Fakita bug repelling device

  Sep 8, 202610 min

  It turns out that Russia does have a huge mosquito problem in some parts. I didn't know that. This unit is basically a self regulating pad based insecticide vapouriser. It takes standard pads that are preloaded with a pyrethrin oil. When the unit is active it heats the pad to slowly release a small quantity of vapour that affects the nervous system of insects and inhibits their normal behaviour including biting. Pyrethrins are based on a natural plant extract from a species of chrysanthemum that has a long history of being used to deter insects from crops. Most devices like this use a synthetic pyrethrin like transfluthrin, allethrin, metofluthrin etc. The heater in this unit is based on a PTC disk that adjusts its resistance based on temperature, so it heats up quickly with higher current and then self regulates down to a lower level. The pads often have a colourant added that indicates how much of the oil in them has been used. They usually go from being blue to white. The unit is designed to be powered from the fake Makita (Fakita) themed batteries often supplied with generic power tools. Those batteries tend to have a low-voltage shutoff feature built in, which is important with this unit, as it just acts as a continuous resistive load. This unit came from our favourite supplier of weird technology - AliExpress (not a sponsor). Here's an affiliate link to the item shown:- https://s.click.aliexpress.com/e/_c3wHCjhH If that one doesn't show up in your country, try this link:- https://s.click.aliexpress.com/e/_c3enNm41 And if that doesn't work, try searching for the keywords - makita mosquito.
