IRF840 is not reccomended, its got too high on resistance.

C1 and C2 change to unpolarized UVP series 100uF 25V

I hope the capacitance value is not crucial here. I just placed order for 47uf 25V non-polarised caps.

 

[v4lve lover]

No the capacitance value is not critical, and the mosfet above will work.

@v4lve lover

What is the size of the inserts on the board? 6.3mm version? Thanks

 

[v4lve lover]

Fs1536/nc at TME

Due to popular request im doing another batch of 10. Ive sold 4 sofar so there will be 6PC available.

Price is €35 each.

Cheers,

[v4lve lover]

I have four modules ready to ship!

[v4lve lover]

Bump!

Four modules available

 

[v4lve lover]

all modules are sold.

perhaps i will do another batch if there is enough interest.

Received the first four bords sold a few time ago and they are very well done by @v4lve lover , they also works great.

 

[Bas Horneman]

I suppose they will also work at 2.5Vac to 2.5vdc? Will test it myself...but thought I might as well ask as well.

 

[v4lve lover]

No, they wont work for 2.5VAC to 2.5VDC i think, there is not enough drive voltage for the mosfet in that case. 4VAC to 2.5VDC should be possible through. I used IRL540 mosfets in the latest batches, these have low threshold voltage.

 

[v4lve lover]

Im doing another batch, four remaining of the next batch.

Cheer,
V4LVE

 

[v4lve lover]

BUMP 2 remaining

 

[v4lve lover]

Bump, two modules ready to ship

 

[v4lve lover]

bump, two modules available

 

[v4lve lover]

Bump, ordered boards for the next batch

 

[v4lve lover]

Bump boards came in, need to order parts

 

[v4lve lover]

bump, will finish 20 modules by friday, PM when interested

 

[v4lve lover]

Bump, 20 modules ready to ship
