Speed Controllers

[razerdave]

I will bring the two prototypes to the AWS so you can see the size but I don't think I will ever convince David to have connectors

Nope

Although to be fair I much prefer the second board now it's all compacted to the size of the actual board .

im guessing the lemon Rx failsafe properly? picked up a couple of my ant but have yet to test them properly

[peterwaller]

Yes they do failsafe.
The throttle channel failsafe position, which is the one normally used for the weapon, is set when you bind it to the transmitter to what ever the throttle stick is set to at the time, so you can set it where you like.
The other channels fail to no output pulses which with most controllers will cause the robot to stop.

I am now happy with the new board and intend only to offer these controllers other than in exceptional cases.
As before I only build them for people I know who pay via paypal and I can offer the two connector option shown below.
Option L/st straight connectors

Option L/ra rightangle connectors

The units will cost £40 + £2 P&P which includes the receiver, loom, and bind link.
There may be a third option later with some flying leads depending on my finding an easy and reliable way of connecting them to the board.
With the receivers on about a 3 week turn around I may not always be able to turn them round in a week.

I have done a little more work on the new controllers and I think I have come up with a better layout.
First the bind pins are now right angle and the the fairly bulky white connector has been replaced with a 6 way right angled header.
The power leads which have the red JST connector already fitted are soldered to the first two pins so they cant be plugged in the wrong way round and the motor leads are plugged in using a 4 way version of the standard servo connector.
For those of you ( David ) who can't stand the idea of connectors you can if you like solder the motor leads to the other 4 pins although the shell and 4 pins only weigh 0.6 gms so by the time you add the solder and sleeves you are only going to save about 0.3 gms.
I have also decided to fit a small red silicon sleeve to the full battery voltage pin on the servo connector to avoid damage by plugging in servos in the wrong position.
Here are a couple of shot af the now standard version, one with the motor and servo connectors plugged in.

Has removing the white connector changed the cost and the overall weight of the board ? I ask because I am looking to buy one or 2.

[peterwaller]

The weight of the unit is 8.5 gms but that now includes the battery wire and connector but overall with the motor connector and wires as well it has gone down from 11.2 to 10.7 gms.
The unit is now a couple of mm thinner at 32 x 32 x 10.5 mm and the cost is still £40 plus £2 P&P including the receiver, motor loom and bind link.

[peterwaller]

I have recently had a couple of enquires for more information on the controller I make and having looked through the thread I now realise how spread out and difficult to find it is so here goes at an attempt to clarify it.
First I only build them for people I know or meet at antweight event.
The controller includes the Lemon DSM2 compatible receiver and so the unit is only compatible with DSM2 transmitters such as DX6i, DX5e, MLP4DSM but not the DX6.
The unit is 32 x 32 x 10.5mm and weighs 8.5 gms including the power lead and connector with a further 2.2 gms for the motor loom which is supplied.
It has a 5v BEC capable of supplying up to 1.5A on two cells and drive / steering mixing is built in. This is elev/ail mixing so single stick operation on mode2 tranmitters and drive on the left and steering on the right on mode1.
There is a 4 pin connector for the third channel, the first 3 pins take a standard servo connector and the 4th pin sleeved in red brings out the full battery voltage for high voltage servos.
A standard 2 pin connector is available for the bind link and a link is supplied with each unit.
The motor drive is 2.4 Amps continuous on both outputs and the controller is rated for driving the following:
2 high power motors or 4 standard motors on two cells or two standard motors on three cells.
The units cost £40 + £2 P&P by Paypal only.
The picture below shows one unit as delivered and one with the motor loom and a servo plugged in.

As most of you know I got into building speed controllers almost by accident having made some for myself and then for other people by request until I got into it on a fairly regular basis.
Now there is a good local alternative which is also cheaper (NanoTwo) I feel it is a good time to stop so I shall not be offering controllers in the future.
If any one has a problem with an existing recent unit then they can still contact me for help but otherwise I am retiring from the controller game.

[razerdave]

I understand why you wish to quit making the boards but it's still a massive shame, the latest board is everything in one (mixing, DSM2 compatible, Voltage selectabilty for the servos) and would have been great for anyone starting off on a budget (Dx5e mixing, 'nuff said).

Thank you for all the help over the years with the controllers
