Tech Help - Projects Page / Harbinger One 2015 not working...
Last post by Kardnez - March 14, 2025, 03:57:33 PMHello,
I've finished building my Harbinger One (2015), but it doesn't work. The bulb glows continuously but quite dimly, and can only be adjusted with the Gain control. The Offset control has no effect on the bulb. The operating voltage is 18V. There's no signal coming from the circuit either, only in true bypass mode. I've checked the components without success and searched the board for solder bridges and cold solder joints. The Speed ��Pot is connected correctly. I've measured transistors Q11 and Q12, as well as capacitors C23, C24, and C25. When turned on, LED 1 flashes once.
The LFO isn't working, but as I said, there's no signal coming from the circuit either.
What could be the problem?
Thank you very much
Holger

General Questions / Re: Total recall
Last post by madbean - March 13, 2025, 05:25:16 PMYes, but you should use a 1/4W (or 1/2W) for R59 which is 10 Ohm.

General Questions / Total recall
Last post by badzuri - March 13, 2025, 03:26:44 PMCan I use 1/8 watt resistors for total recall in stead of 1/4 watt?

Good on your kid for designing the board too.

Build Reports / Breath of the Wylde
Last post by mjg - March 12, 2025, 09:39:03 AMForgive me Bean, for I have sinned. It has been 3 years, 8 months since my last pedal build confession.
This one came about because my son expressed an interest in building a pedal, and he chose the Zakk Wylde branded MXR ZW44 distortion, and ZW90 phaser as something he wanted.
I whipped up a schematic, then set him up with a quick lesson in board layout in Eagle, and let him design the board. Manufacturing was done by Elecrow. He had a great time doing the board design.
Next step was soldering, and he completed the ZW44 side of the board, and it fired up first try, which was impressive. I then soldered on the 4 SMD parts, and left it for him to finish up the phaser side.
About a year later, after bugging him every few months to finish it, he finally admitted that maybe I should finish it for him. Half an hour later, it was done.
I've fitted it into a Jack Daniel's metal tin, which is apparently appropriate for the artist involved. As it's thin metal, and is prone to dinting and bending, I've put the switches and board onto some steel sheeting, to make it a bit more solid. The power and jacks are connected with detachable plugs, for easy access if any repairs are needed.
The lettering has been done using a Cricut cutting machine with some sticky vinyl. It was a bastard to get all the lettering lined up, but I'm super happy with the end result. It almost looks like it is part of the original print on the tin.
Gold numbers on the knobs, and orange leds, to invoke the colour of the drink.
Overall, it's such a tacky concept, but perfect for a teenage boy who's just shy of being legally allowed to drink (here in Aus). And just to show that class is something you have to learn, and teenage boys just don't tend to have it... the pedal with his matching Jack Daniel's brand flying-V guitar. So tacky that it almost works.

Tech Help - Projects Page / Re: Anamorph question
Last post by madbean - March 11, 2025, 11:32:17 PMIs this in stereo or mono? In stereo mode I would say there is definitely a "bloom" effect in mixing the wet and dry signal. This is due to the wet signal being inverted before mixing to the stereo output. But,it should not be present in mono output.
