 :-+ If that does not push the BB3 over the funding edge...

It already has started to go faster right after christmas. I guess more people spending their christmas money ;)

Well time to look into ordering components.

I'm hoping Dave has pushed this over the edge. But it is SO MUCH MORE than a power supply.

It's the BB3's versatility that makes it 2019's standout open-source bench instrument.

Whhoo-Hoo!! You must have been refreshing the page as often as I was.

All of a sudden that stretch goal looks achievable.  :box:

Well done!

I'd love one of these but can't justify the cost, sadly.

EEZ BB3 protection mechanisms
« Reply #112 on: January 01, 2020, 07:03:59 am »
A short video about various built-in protections like the detection of cooling fan failures, output states on power up and protection trip, full-range OVP crowbar, display lock, module power failure, reverse polarity protection of both power outputs and remote sense inputs, power recycling with connected battery, and inhibit mode.

Just made an order for the bare boards + enclosure (sorry it took so long to do).
Congratulations on meeting the funding target!

Simple curve tracer
« Reply #115 on: January 04, 2020, 07:33:06 am »
MicroPython scripting is used to create curve tracer for NPN BJTs and N-ch MOSFETs.

Shortly we'll enter the final countdown (last 48 hours). We are missing little below $6K to reach stretch goal ($100K). After that campaign will enter pre-order period when the following changes will happen:
  • DCP405B module, and all kits that include it, will no longer be available due to lack of interest. 2-ch "full" version will stay and 4-ch "full" version will be introduced.
  • Price of BB3 Enclosure & Bare Boards will be increased from $145 to $160, 2-ch "full" version from $599 to $650 and 4-ch "full" will cost $750.

Current ranking list of our backers still include US, Australia and Germany on the first three positions. Actually, most of backers comes from California, strange isn't it :).
We are really missing this time folks from Austria, Italy, Spain and Russia.

Thank you for the inspiring design and congratulations on meeting the funding goal.

What will happen to the price of the "BB3 - Starter (Without Peripheral Modules)"?

I'm still in doubt wether to order this in addition to the full unit now. I want to have space for future modules because I see a lot of potential for interesting modules (loads, low power measurement, references, waveforms, USB PD, ...).

Thanks for your support. This pledge level is not yet discussed with CrowdSupply team. In a worst case scenario it price could rise for a few percentage.

Thanks for the details on the changes. What's the precise cut-off time in UTC for the campaign?

Any more thoughts on making it possible to keep front-panel USB at least as an option if you make the $100K stretch goal?

It looks like you can see the time left to run on the top RHS of this screen. About 46 hours to go as of this post. https://www.crowdsupply.com/envox/eez-bb3/updates/our-campaign-is-live

It will be difficult to keep both versions if we are going to move connectors to the back. I have few enclosures with connectors on the front left from test run is someone is interesting, but MCU module one has to build its own, i.e. order r1B6 PCB and parts, or move parts from assembled new design (r2B2) and solder them to the r1B6 PCB.

Yeah, when I asked it was showing only days. Changed shortly after I asked. ☺

Oh, I was hoping for using cables to remote the port from the board to a case cutout, as typical for PC motherboards and USB ports in a case. But I'll "stay on the reservation" and get whatever everyone else gets.

My idea is to use this type of cables:





I think that we'll need another round of voting like:

1. Move both sockets to the rear
2. Move only Ethernet socket to the rear

New MCU is presented here (if we are going with solution #1), but another revision will include jbb's suggestion to move BOOT0 switch from AUX PS to MCU.
