WTB: Little Bee Current Probe, used or make a new one for me

[the_cake_is_a_lie]

I missed the crowd sourcing campaign, it's sold out on Mouser and Weston posted it's discontinued. I can pay $100 USD flat for a used one made by Weston, including shipping to ship to me in the US.

I don't trust myself to make a sensitive piece of electronic equipment. If you make a new one from the GitHub design, I could pay $160 USD, half upfront. I'd have to see a decent 20 Hz - 20 MHz bode plot comparable to the original's before shipping.

I only need to measure current distortion 5A and below, so this seems perfect for me.

Whats wrong with the used one?

Sourcing the parts is very difficult.

I don't know, all the parts are readily available on Digikey. Just for the IC it's around 38$

hehe yes, he is looking for an used one or want someone to make one for him. The title says it all.

Why somebody would post a "WTB used or new" if he already had access to one ?

Thanks all for the responses. Alas no offers in my inbox.

I can step up to $110 used if it looks mint in pics. Problem with DIY is I have no experience with making or calibrating electronic measuring devices. I also don't have a PIC programmer. The price point is low enough that I'm happy to pay a premium and avoid the time and labor.

I don't see a BOM with links to buy the components but on the current-sense PDF:

• HMC1041Z: 11.49
• AD8129: 5.33
• PICO16F1776-ISS (I think is the same): 2.65
• MCP1640 (not sure of packaging): 0.81
• 2x TLV3542: 2x1.80
• 2x TMUX1219: 2x0.73
• 2x DMG6601LVT-7: 2x0.39

$26.12 + 6 Shockley diodes, 3 LEDs, 2 "small" ferrite beads, 1 fuse, 1 SPDT switch, connectors and passives. I assume 1% resistors, 10% 1uF ceramic, 20% uF electrolytic and 20% 4.7uH inductor. I'd pay extra for tantalum 22uF.

You're welcome to use any official distributors. I don't mind non-RoHS components or leaded solder.

What about the 3D printed clamp portion?
PCBs?

Oh shit my bad, I thought Weston WAS offering a used one for that price.

[the_cake_is_a_lie]

I don't about PCB needing to be 4 layered or needing to 3D print the clamp, fair points. If one person prints the clamp and one person does the assembly, I can pay each of you a cut of the $150. I was really just expecting someone to have the current probe collecting dust. I don't use everything I buy.
