Wiring input voltage directly to 24V PSU and output ground to the original 24V mainboard fan connector is necessary to a) not fry your mainboard transistors and b) allow mainboard to start/stop the fan. Wire coloring in the pictures is red/orange:...

Remove the top cover, two screws that hold the transistor heat sink, and the electronic board. Also remove the transparent plastic film. Place the two inner supports as shown in the picture (#2) and then reassemble the PSU. Attach two screws with...

The chosen transistor for the inverter is a BC547, a reference in signal amplification, so you shouldn't find it difficult to locate. This circuit, unlike the ones designed for commercial purposes, does require that we identify, in our card printer,...

HP41C Full Nut with the two-transistor PCB. This design was modeled in order to take as much advantage I could for finding bare PCB areas to glue the lower screw post assembly onto. Other PCB variations would benefit from a different custom...

The computer was transistorized and so interactive - it didn't just use punched cards. That led to a few innovative firsts on the PDP-1 but also beyond. The PDP-1 was somewhat based on the TX-0 and TX-1 computers where magnetic core memory cam...

The enclosure has two places for 50*11 fan holders (my fans are 10.5mm thick to cool the transistors and drivers) and a wide opening to put an extension card (replication) on the sensor and endstop connectors (opening of 30mm) and a compartment for...

I created a PCB that holds a ULN2803A octal darlington transistor array to drive two stepper motors. It also contains a DS1302 real time clock chip, its crystal and battery. The board is driven by an Arduino Pro Mini. Eagle files are included; I used...

Ingredients: * PIC12F1572 microcontroller * BC 337 NPN transistor * Several LEDs * Cheap handset with a 2.5mm 4-pin jack * Various resistors * Generic Micro USB to A lead * Keyboard key for the hang-up switch * Multiple 3D printed parts * Four...

Normally I control steppers using NPN transistors but as these motors are bipolar I had to use a 4 full bridge drivers to control the two motors. Note that when the motors are turning at a very low speed the driver can get a bit warm. I may change...

Because of the MOSFET transistor FDD8780, it can be used to load up to 50W without any extra cooling. There are several extra options available: In Configuration_adv.h file, uncomment them by removing the '//' Line 263: #define CASE_LIGHT_ENABLE...

The transistor and washer are now designed with a clip-in attachment through the side holes; I strongly recommend gluing in place for a permanent connection. Two plugs have been uploaded to attach other pieces through the connector (right or left...

So I modded that lamp, added: two brightness steps: 50%, 100% (400mA, and 700mA) replace radiator to better one with fan timer More info about red light therapy code and schematics: https://github.com/polihedron/PowerLED-timer BOM: PAR38 Bulb...

Here's what you'll need to buy: * Two bistable relays rated for 5 volts * One ATTiny85 * Two low-voltage switches * One high-voltage switch * A LED * Resistors (five 10kOhm, one 100kOhm, and one 470 Ohm) * Capacitors (three 100nF) * C-Mos 2N7000...

Fun fact: bipolar junction transistors can be used as current sources, outputting a set current regardless of the supply voltage or load resistance! ...You can find other maker coins made in the class here:...

Several methods are available for pulsing this device, and I prefer the simple one-transistor Bedini SSG circuit. Parts needed include #6 - 32 X 3/8 inch brass or stainless steel bolts at all locations. Magnets should be 1 inch x 1/4 inch x 1/8...

You can print your own one with the desired size.\r\n\r\nThere is room on the vertical support for installing a DC-DC converter (XL 4015) to use power supplies with 12 volts or more.\r\n\r\nA MOSFET has been added to the circuit to turn off the...

Here's what you'll need to make one of these: * Springy wire (like paper clips) for the battery contact - check its resistance (less is better) * AA battery * LED (I used RGB LEDs and white warm steady light versions) * On/off switch (project using...

You can also mirror the designs to fit your needs.With an ESP8266, a 1,3 inch OLED display, some transistors and some bright leds, this was pretty easy to setup. When creating the lithophanes, make sure that the uploaded images are the sames size on...

It also controls the fans within the case using PWM signals and a transistor, so as the temperature rises, the fan speed increases accordingly. The fan speed is displayed as a percentage, and there's even a graph to represent the temperature readings...

The 80mm fan blows directly over the Stepper motor drivers and power transistors, maximizing performance. These 80mm fans offer excellent airflow strength and are easily found online, unlike smaller 40mm fans. This design allows users to easily swap...

All parts can be printed with normal settings, except the diffusor.DiffusorPrint at 0.2mm layer height (first layer as well!) with, I'd recommend White PETG, as PETG seems to be a bit more translucent than other plastics, but try experimenting...

Two transistors in the circuit have 2SB1182F5/Q Ik max = 2A, diode RB051L ~ 3A. My li-ion charger is 0.7A, so the radio circuit can be modified. It's not difficult to tune the circuit to provide more charging current. The charging current, set by the...
