DIY cables for power hungry pedals (& how to use a Multimeter)

[@danielcaparroz299]

Thank you so much, helped so much to solve my problem! 30 mins of work and voila! Cheers from Brazil

This is awesome. I've got my HX working perfectly. Would the same process for your voltage doubler work for a voltage tripler? 3x 9v wired in series for 27v? I have a Tronographic Rusty Box in the post, and it runs from 24v to 40v.

There are splitter cables to connect two pedals to one source. You can use them in reverse as a current doubler without soldering!

Thank you for this. Extremely useful

Hey! Very informative video, but I have a problem. I have a power source Harley Benton iso2 pro, which has 2 outputs with 500 mAh, and 5 with 300 mAh. The problem is when I run the hx stomp with a diy current doubler cable on the two 500 mAh outpus and two analog pedals( sansamp bass driver 25mAh, and a boss oc2 with 4 mAh consumtion) and the power adapter gets very hot. This model of power source is powered with a separate adapter with 12V , 2A. The overall power consumtion of my pedalboard is around 1A, which is half of the capacity of this power source. I tried replace this adapter with another with the same 12V 2A specs and the result was the same, it gets very hot, hotter than it should. Should i make a power quadrupler cable to the four 300mAh outputs to get 1200 mAh for the hx stomp to avoid the heat?

[@DIYguitarGuy]

Hi, thanks for reaching out. Do you have headphones connected to the Stomp? It might draw more than 1A when using them. You can try the quadrupler, maybe it helps. Power supplies do get warm in general and I think these inexpensive ones don't have cooling as the priority.

[@replikasbuzi]

@@DIYguitarGuy wow thanks! So this is the case! I have a jack to headphone jack adaptor constantly connencted to the stomp and I use the hradphone out almost daily. I'm gonna check this today! I'm not an electrician, but I know how to solder and to use the multimeter, but I did not have take in considrration the fact that it could draw more current if I use the headphone out! Thanks again!!!

[@bestprato]

I fear that the current drawn is much greater when you plug in a headset and turn up the volume. Have you checked?

[@DIYguitarGuy]

I haven't but that could be the case, I don't use the headphone output when it's on my pedalboard. If it does draw too much current from one power output, maybe a separate headphone amp connected to another power output can solve the issue.

[@shawnTTshawn]

Could you do a test on pod go? Is the power consumption same at 0.9A?

[@DIYguitarGuy]

I don't know, I don't have a Pod Go

[@kaskas55]

Thanks! Will it be the same concept if the other ends is RCA? (Cioks)

[@DIYguitarGuy]

It will do. Just make sure which part of the plug is the positive and negative side and use a multimeter to confirm the power outlet is truly isolated. But knowing Cioks it's probably isolated. Good luck!

[@kaskas55]

@@DIYguitarGuy thanks for the reply. Im going to diy the current doubler since the CIOKS cable is not available where I live. Cheers!

[@DIYguitarGuy]

@@kaskas55 Cool, let me know how it works out!

[@jst601]

Do you know of any way to test the actual output of each individual output on units such as that Iso? I need to verify my Iso 1. I think it's delivering much less than 450ma at each output. The specs say that each output will output @ max 500; it does not state a *minimum* milliamp output. I cannot power my Dept 10 dual drive with any output of my brand new ISO 1. The unit shuts down within 10 minutes or so. It pulls about 430-440ma. I tested it on my true tone milliamp tester.

[@DIYguitarGuy]

Hi, there are Electric Load devices which will simulate a load wile measuring voltage and amperage. But what I guess in your case is that either device gets too hot and shuts down or there's too much connected to it. Reading the quick start manual it states that it can't exceed 18 Watts in total, so when every output is used they can't draw more than 250 mA each.

[@TomaszGutka]

Can I triple the amperes by using daisy chain cable to connect 3 12V 300mAh fully isolated outlets of T-REX PowerPlant Chameleon to power up Friedman IR-X that requires 12V 800mAh? Same polarity, same voltage as 3 outputs, sum of 3 outlets has sufficient amount of mAh and all outputs give equal current, but is the regular daisy chain cable but plugged in reverse (instead of powering 3 pedals, it's plugged into 3 outlets of power supply with just 1 pedal at the other end) what I need? Or it can only double but not tripe? Are all regular daisy chain cables parallel so that they double the amperes and not the voltage?

[@DIYguitarGuy]

Yeah that should work. Daisy chains are in parallel so when you plug them in reversed, they should add all the maximum currents, in this case triple it. T-Rex says the Chameleon has isolated outputs, so I don't see a reason why it shouldn't work. Let me know how it works out.

[@raynunez6027]

Do you have any update on this? Did it work?

[@TomaszGutka]

@@raynunez6027 it did, but eventually Friedman made an update for the firmware that allowed running IR-X with a lower current. I also changed T-Rex to Cioks DC7 where it's no longer the problem
