For sale: Delta Pulse boards

[eclipse]

I've got few boards left for a Delta Pulse.

They are in pack of 2: top board is Sound, Power Supply, Low battery; Bottom board: oscillator, transmitter, amp, sampling.
The 2 boards are connected with 7 solder joints. Boards size is 90x100, designed so that they can be plugged in 100mm casing with rails.

There are no differences with the original board except for the mosfet driver, decoupling caps for everything (X7R 2.5mm pitch), 12V regulator (can be omit) to be powered by 4x18650 battery pack, bi-color single status LED.

I'm also including NOS LF357 - 2 different pcs. If you need the mosfet driver (MCP1407), I can include that too under few conditions, it can be omit but it will help improve turn on/off times of the mosfet, solve some problems you can get with some 556 chips, etc. (same as for the STTH1210D)

The cost + shipping is 22 Euro / 25$

Yes, I deleted some old messages, btw your box is also full
I'll send you the info.

On the mosfet driver basically the deal is that I don't have them in stock but I'll be making an order with mouser, so if you want the driver, there will be delay 4-5 days,
also plan B is to pull out from my build. I have made 2 builds, so I can spare 1.

received all today, many thanks all fine

take attention while soldering
the distance at some traces to copper mass is very small
take fine solder wire 0,5 and check all solder joints after work
good luck

eclipes can you upload a video of your finished and working delta pulse if you have some free time?

wow just few days till got delivered after postage, nice. use solder no clean flux and clean with isopropyl alcohol. i havent made any videos nor got time to do that. I use frame coil for it 12 windings 1mm2 wire - 650uH inductance, 1.9 ohms with the cable.

I will send you the files you requested. Also note on Stth1210 diode it should be mounted the other way around - not like the layout on the board.
