Win a Tenma Power Supply

A great use of this PSU would be to create and test safely, your own homemade components! Always fun to try replicating traditional components(Resistor, FET, Coils, ect) with items around the house.

Hi Hasan,

My brother has a bearded dragon that I gave him several years ago. Since we live where it get very cold in the winter he has his grandkids catch insects all summer which he freezes so the "Dragon" as he is called will have frozen TV dinners all winter. The dragons make a great pet.

I have a pet bearded dragon that spends its days under UV and infrared bulbs during the day, and near heating mats/ceramic infrared bulbs at night. I always wonder if it appreciates having so much AC power just a few inches away from it. I would love to power it’s heat from clean and stable DC power so it’s bathed in a soothing DC Electromagnetic field rather than a harsh monotone 60Hz AC EMF. I try to take it outside on sunny days but ... winter is coming.

If the supply is adjustable with a control signal then I could even make it turn on slowly to mimic the sunrise and sunset. A mere relay to control the lights is too abrupt.

Would go great with my Model 72-375 Freq counter!

     In present day technology the number of electronics devices are increasing day-to-day in households, offices, colleges, hospitals, restaurants, theaters, function halls, parks, digital worlds, streets, from mini devices like wrist watch to industrial robotics. As the technology increasing parallel the learning skills, maintenance and replacements of minor components are also increasing. To make the perfect replacements of the damaged components the power rating should maintain exactly their are many power sources developed by the companies available in market but he one which I was exposed by this event was exceptional to hear the salient features of TENMA Power Supply.

Tenma power supply which was introduced in this document really help the professionals like me to utilize it in different way in different areas.

I am glad to brief the importance of the Tenma Power Supply in day to day usages in different fields on my personal experiences and detail study of documents (datasheets, videos, blogs, etc) on the kit. It can be used in many fields such as:

College Laboratory Kits:

In colleges/Universities their will be Electrical, Electronic and communication Engineering courses, Electronic Sciences apart from their theory they will be different types of Laboratories like Analog and Digital lab, Communication system design Lab, Digital circuit design lab, Microprocessor & Microcontroller lab, Robotics Lab, VLSI, Phyicsl Science Lab, Electronic Science Lab, etc. In each and every lab their will be electronic and electrical devices running at different DC voltages.  In our university I am the Asst.Professor and Lab Coordinator and we frequently upgrade the lab facilities with latest devices and systems to make the students up-to date on the technology. In our institution lab their are about 20 different types total above 1500 number of DC power supplies with different standard ratings useful in different experimental purpose in different individual laboratories, about 4000 students are benefited in the academic year by their usage. Some of the power supplies in Physical Science Lab are shown below:

When I was teaching about the series and parallel combinations of the battery sources some of the student raise a doubt that "why can't we add the regulated power supplies in those combinations in our lab similar to batteries". Then I answered their was no such smart device at present, but after careful observation of the manuals of TENMA kit through this document I was wondering to see the kit consists of series and parallel combinations and also Master-Slave tracking and soon salient features. It will be good opportunity to win the kit to showcase the importance of the kit in our institution to replace the damaged power sources with the TENMA kit in feature. In my opinion this kit can replace at-least 10-15 types of power sources kit as a common kit in Lab. I feel if this kit of one can be used to eight different experiments in our Lab and the space occupied by the kits will be reduced on the workbench.

It can be used in lab experiments like electromagnet power supply for hall effect, electric tuning fork vibrator power supply, PNP & NPN characteristic studies, Diode IV characteristics studies, Ohms law verification, Laser sources, Solar simulator light intensity, AM, FM circuit design for communication, Stepper motor power supply for robotic arms, Digital logic circuits design, Microcontroller kits, etc. If the manufactures power sources was suddenly damage the TENMA kit can be used as an alternative by adjusting to the suitable power rating until it is replace by companies product in-order not to disturb the students lab.

Maintenance and Repair shops:

In the present days digital world all the electronic items are digitized and their power supplies are purely DC sources. If the components damages, for replacement a proper power rated components should test and fit. TENMA kit has varying power rating options with two different channels which will help the technicians in reparing and supplying a proper power rating for Television set, Audio devices, motors, etc equipment. Lead acid batteries of different size and rating can be charged using the TENMA series and combination feature. It help the technicians in designing the recommended power sources for mobile phones, laptops, gadgets, wearable devices when their original power adapter got damaged.

Electrical and Electronic Shops:

When purchasing the electronic items initially we check the functioning and conditions of the items. In testing the devices may have different power ratings based on the manufacture company specification it will be tough job for the seller to place the multiple power sources on his test bench to show the device working. If the single power system like TENMA kit, it will help them to select different power ratings from the common kit so that the test bench will be free to place the testing components. Like wise the TENMA kit can be useful for the electronic items seller

     In my opinion after personal experience in various places like in students labs, research labs, maintenance and repair shops, seller shops the TENMA kit will be economic and handy device. The example briefed in this comment was limited but their are enormous amount of usage of the DC power source in different applications. If I have the opportunity to utilize the kit I am willing to showcase it importance in using one instead of many power sources in our institution to upgrade the damaged DC power kits with TENMA power supply kits and to the community members with different blog postings. After seeing the detail specifications of the TENMA power supply kit everyone like to have it because it draws such attention with its salient features.

Thanking you.

in this device we have 4 displays - maybe "hack" internal PCB and display "current" time I see 2 ways - connect to internal PCB with display and add there some custom logic or mount some servos on knobs and set voltage to actual hours, others for minutes etc.

Every electronics should build a clock - why not from PSU?

Why not break down all the old disc drives, snatch up the diodes and the sliding trays, make yourself a laser engraver, with a regulated power supply the laser would last way longer than normal, as long as there isn't any spikes.

Or better yet, get a piece of metal you can etch on to, like a blank coin, outline something on it with nail polish, put in a bowl of salt water connect positive to object and negative to a line going into water, wait 10-15 at 12 Volts and viola engraved with your kids birthday.

I wouldn't call this creative, more like a solution to a problem I ran into. My work area is a little dark as it is in the corner of a room.  I bought a cheap desk lamp and a inspection inspection mirror . The mirror was on the expensive side but the lamp was cheap. Anyway one day working on some stuff my lamp began to flicker and then it just quit. So I turned on the inspection lamp on and PooF . That quit as well. So in the darkness i took them both apart and found check electronics fried. So I went and installed some new high powered leds and wired it directly to my bench power supply. It is a dual channel so I am not completely without power options. But it made for a nice fix and with being able to control the current . I do not have to worry about smoking the new leds I installed.

Unfortunately, I am not that advanced in electronics to find a unique way of using this power supply as I have seen in the comments, but I am getting into electronics and would use it from charging batteries, powering various rc drone components, testing them, powering the new arduino uno and everything I could think of. In short - experimenting, hopefully not burning down my room . Learning about it all and it is fascinating for me.

I will use the power supply for powering BMW modules,  for diagnosis and repair
